Introduction<br />
The <strong>I+ME</strong> CAT (CAN Analyzer Tool)<br />
CAT is an improved portable CAN Analyzer Tool. It is designed to connect a PC with RS232 interface<br />
to CAN (Controller Area Network). With its features it is an ideal general-purpose hardware for<br />
automotive analyzes and diagnostics on the single wire CAN, the mid speed CAN and the high speed<br />
CAN.<br />
<strong>I+ME</strong> designed CAT specially to use together with Laptops for testing a vehicle. Therefore the user can<br />
configure the layout of the windows application to his or her specific needs. E.g. it is possible to enlarge<br />
the used fonts of received signals or frames.<br />
With CAT the user can visualize and influence bus traffic within a CAN network. CAT supports even<br />
some Diagnostic Services in accordance to ISO 15765.<br />
CAT allows to transmit messages to the CAN bus, the user may set filter conditions to focus on special<br />
CAN ID or on special CAN messages. Trigger functionality supports in analyzing the bus traffic.<br />
The logged data can be exported into text files that are readable by standard PC applications, e.g. Excel.<br />
In this way the user can generate statistic diagrams etc. to analyze the acquired data.<br />
Discover CAT by browsing through this Help document or just use it in real at a CAN system. As long<br />
as the user is not familiar to the CAN bus and the usage of CAT there must be precautionary measures<br />
to assure that the CAN system cannot be destroyed or do any harm to the environment.<br />
<strong>I+ME</strong> <strong>ACTIA</strong> appreciates comments for the usage of CAT. Send faxes or e-mails to the After Sales<br />

System Requirements<br />
The host PC has to fulfill at least the following requirements:<br />
- Windows 95, Windows 98, Windows NT 4.0, Windows ME or Windows 2000<br />
- 200 MHz IBM compatible PC,<br />
- 16 MB RAM,<br />
- 10 MB free HDD space for CAT software,<br />
- additional free HDD space for databases,<br />
- VGA graphic adapter or better,<br />
- COM port 1 or COM port 2 available,<br />
9
Software Installation<br />
Note: It does not matter if the Software or Hardware is installed first.<br />
Installing the Software<br />
1) Insert 3.5" floppy (disk1) or CD ROM and start SETUP.EXE.<br />
2) Follow the instructions to install all necessary files to the hard disk.<br />
3) Start CAT by clicking on the corresponding icon within the program group.<br />
CAT will look for the Hardware connected to COM 1 or COM 2 of the PC. If the Hardware has been<br />
successfully installed, the application will start directly. Otherwise a message box will inform the user<br />
about missing Hardware. Acknowledging this message allows the use to work in the Offline<br />
respectively Diagnostic Offline mode only.<br />
Assuming successful Hardware Installation CAT LED switches from red (Power on State) to green<br />
displaying the Firmware-Download then indicating the Offline State by blinking 2 times: red, green,<br />
pause.<br />
(See the LED Interpretation for more details.)<br />
10
Installation<br />
Note: It does not matter if the Software is installed first.<br />
Installing the Hardware<br />
CAT has two interfaces. These interfaces are:<br />
• Host interface (to be connected via the 25 pin D-Sub to 9 pin D-Sub RS232 PC adapter cable)<br />
• CAN interface (to be connected via the 9 pin D-Sub to 16 pin SAE J1962 (OBD) CAN adapter cable)<br />
Note: The CAN interface is also the power supply of the tool. Disconnection from the CAN bus<br />
results in loosing the data in the Hardware. The buffer content is stored on the Hardware as long<br />
as you load it up into the application. (See Buffer Handling .)<br />
To install the hardware CAT has to be connected to the serial port COM 1 or COM 2 of the host PC. CAT hardware<br />
COM port is the female 25 pin SUB-D. If the PC has a 25-pin COM port connect CAT directly.<br />
If the PC has a 9 pin COM port connect CAT with the RS232 PC Adapter cable. Therefor the female 9 pins D-Sub of<br />
the PC adapter cable must be plugged into the male 9 pins D-Sub of the PC. The male 25 pins D-Sub of the PC<br />
adapter cable has to be connected to the female 25 pins D-Sub of CAT Hardware. (See CONNECT in Picture above.)<br />
Connect the male 9 pins D-Sub of CAT Hardware to the female 9 pins D-Sub of the CAN adapter cable and make<br />
sure that this cable is connected to a power supply. CAT LED becomes red displaying Power-On State.<br />
See the following Wire Description of the standard CAN Adapter Cable for details.<br />
11
Uninstall<br />
The CAT Software can be uninstalled by using the uninstall feature of the control panel.<br />
13
Re-Install<br />
Before Re-Installing CAT software, it is recommended to copy Databases and Sessions that shall be<br />
used further on into a separate additional folder. Then uninstall the existing software first.<br />
Nevertheless it is possible to Re-Install on the already existing software without having it uninstalled. In<br />
this case be aware that the existing CAT specific files are overwritten by the original files.<br />
This means individually done settings for the diagnostic protocol and templates (see CAT Diagnostic<br />
Setup , Session and ECU Template) will be replaced by the original standard settings.<br />
Additionally the Database folder Db1 and the Session folder S1 will be overwritten. (See Session and<br />
Database Management for details.)<br />
14
System Overview<br />
15
Terms & Phrases<br />
Block Size (BS) The BS (Block Size) defines the maximum number of frames which can be send before another<br />
flow control frame has to be sent.<br />
Buffer Used as synonym for the data of the circular buffer on the Hardware. See also Buffer Handling .<br />
Configurations All the setups that are done to change or modify a session not the database. Though there is an<br />
access to maintain the databases via the menu item Configurations.<br />
CPID Control Packet Identifier. 1 Byte value identifies a packet of data bytes to control and manipulate<br />
ECUs (Devices) externally.<br />
Database The term database is here used to determine the data that describe vehicles by the build in<br />
ECUs, the frames of each ECU and the signals of each frame.<br />
Parts of a Database are:<br />
16<br />
- included vehicles,<br />
- included ECUs,<br />
- included Frames and Diagnostic data,<br />
- included Signals.<br />
Each vehicle contains ECUs; the ECUs contain Frames and Diagnostic data. Frames and<br />
Diagnostic data each contain Signals.<br />
DID Data Identifier. 1 Byte value identifies static information stored in the ECUs.<br />
DPID Data Packet Identifier. 1 Byte value identifies a packet of diagnostic data bytes containing nonstatic<br />
information.<br />
DTC Diagnostic Trouble Code.<br />
ECU Electronic Control Unit. Here in the meaning of electronic boxes that are build in vehicles and that<br />
communicate via the CAN bus.<br />
Filter CAT provides Pass Through Filter only. The data are already filtered by the Hardware.<br />
Frame The frames are the messages that are transported via the CAN bus.<br />
FSA Functional System Address. Identifies a group of ECUs that build up a functional system.<br />
Layout The layout means the desktop and desktop configuration of CAT application.<br />
Padding Padding means to fill up the Data Byte Field of CAN Frames with 0's, so that the frames always<br />
contain 8 Data Bytes.<br />
Separation Time The ST (Separation Time) defines the minimum amount of time in ms, which must be between<br />
consecutive frame transmissions of a multi frame message.<br />
Session The term session is here used to describe the settings done to work with CAT<br />
Parts of a Session are:<br />
- the link to a database,<br />
- the frames that shall be displayed in the frame list window,<br />
- the signals that shall be displayed in the signal list window,<br />
- the configured frames that shall be transmitted inclusive the conditions,<br />
- the filter conditions,<br />
- the CAN setups (selected or configured physical layer / Baud Rate),<br />
- the buffer division sizes,<br />
- the buffer content (when uploaded)<br />
- the layout settings for the graphical user interface, column / fonts sizes and windows<br />
arrangements.<br />
Signal The signals are the interpreted data of the CAN frame. See also chapter Signal Types.<br />
Trigger Trigger used as short form for trigger event. There is a trigger event when the trigger conditions<br />
are fulfilled. Trigger events are not necessarily frames that appear on the bus. See also chapter Configurations |<br />
Trigger.

Application Structure<br />
CAT can recognize four different modes. Depending on the mode the user can analyze the traffic on the bus using<br />
different (Views) windows:<br />
- ONLINE Mode<br />
Frame List View<br />
Signal List View<br />
Status Bar<br />
Additional to the View windows to monitor the CAN bus, there are Online Control windows to allow the<br />
user to send frames and diagnostic services:<br />
Transmit Table<br />
Main Diagnostic Launch Table<br />
- OFFLINE Mode<br />
Frame List View<br />
Signal List View<br />
Trace List View<br />
Status Bar<br />
Additional to the View windows to monitor the CAN bus, there are several windows to configure and set<br />
up our system.<br />
- DIAGNOSTIC ONLINE Mode<br />
Diagnostic Online View<br />
Additional to the View window to monitor the request and response messages for one diagnostic service,<br />
there is an Online Control window that allows to launch the service.<br />
- DIAGNOSTIC OFFLINE Mode<br />
Diagnostic Output<br />
Status Bar<br />
In each mode there can be Status Information windows displaying Status Information e.g. about the<br />
buffer upload process.<br />
CAT Application consists of an (opened) Session and a Database the session<br />
points to. Another important part is the buffer content.<br />
Main parts of a Session are:<br />
- the link to a database,<br />
- the layout settings for the graphical user interface (e.g. windows arrangements),<br />
- the configurations of filter, trigger, transmit frames and diagnostics,<br />
- the system setups for the buffer usage and for the connected CAN bus,<br />
- the buffer content (when uploaded).<br />
Main parts of a Database are:<br />
- included vehicles,<br />
- included ECU's,<br />
- included Frames,<br />
- included Signals.<br />
Each vehicle contains ECU's, the ECU's contain Frames and Frames contain Signals.<br />
Buffer<br />
The total 50.000 frame buffer contains two parts:<br />
- the Normal Buffer,<br />
The normal buffer contains all CAN data that are received from the bus (unless there is no filter) and the data that are<br />
transmitted by CAT.<br />
- the Diagnostic Buffer.<br />
The diagnostic buffer contains the diagnostic data that are received from the bus (unless there is no filter) and the<br />
data that are transmitted by CAT.<br />
See Buffer Handling for details.<br />
18
! If the user disconnects the Hardware from the Power Supply (by disconnecting the CAN<br />
adapter cable) and has not uploaded the buffer the user will loose the logged data!<br />
19
Online Mode<br />
The Online Mode of CAT allows visualizing and logging the traffic on the bus. See Changing CAT<br />
Modes for details about how to go Online.<br />
For visualization the Online Mode offers:<br />
20<br />
Frame List View<br />
Displaying up to 10 frames that has been selected to be displayed<br />
Signal List View<br />
Displaying up to 20 signals that has been selected to be displayed<br />
Status Bar<br />
Displaying always the most recently received frame from the bus.<br />
Additionally the user can open:<br />
Transmit Table<br />
Displaying the names of up to 10 frames that has been defined to be transmitted.<br />
Main Diagnostic Launch Table<br />
Displaying the addressing of some Diagnostic Services that are supported by CAT.<br />
Note: The configuration / setup of the Main Diagnostic Launch Table is even possible when being<br />
online already by opening the Main Diagnostic Setup dialog under Configurations.<br />
Being Online the received and transmitted data are logged to the buffer on CAT Hardware. The Buffer<br />
content is first stored only on the Hardware. Only after uploading the buffer there is access to this data<br />
in the Offline respectively Diagnostic Offline Mode.<br />
! If the user disconnects the Hardware from the Power Supply (by disconnecting the CAN<br />
adapter cable) and has not uploaded the buffer the user will loose the logged data!<br />
CAT allows in online mode the following actions:<br />
- Activating the self defined Filter ,<br />

comfortable way to analyze the logged data. See also Buffer Handling .<br />
22
Diagnostic Online Mode<br />
The Diagnostic Online Mode gives the user the ability easily to send diagnostic services even periodically and to see<br />
directly the corresponding responses. The set up of a diagnostic service to be transmitted is much easier in diagnostic<br />
online mode than in online mode. Opposite to the Online Mode it is possible to visualize the whole communication<br />
process: Request, Multi-Frame Responses and also Flow Control Frames.<br />
Additionally the DTC read out by service "Read Trouble Codes" are converted from hexadecimal DTC data into the<br />
SAE DTC code.<br />
The Diagnostic Online Mode of CAT allows visualizing and logging the diagnostic service that has<br />
been launched and the response to this service. See Changing CAT Modes for details about how to go<br />
Diagnostic Online.<br />

Hardware<br />
43
Hardware System Structure<br />
CAT Hardware system consist of the Interface Box with the implemented LED – usually called CAT<br />
Hardware - and a PC Adapter Cable. See the Hardware Installation for details about how and when to<br />
use the PC Adapter cable and how to connect the CAT Hardware system to a CAN system.<br />
CAT is a CAN-Bus tool that operates in combination with a standard Laptop or PC. The main parts are:<br />
- CAT Hardware,<br />
- the main application program (AP) cat.exe.<br />
Due to the fact, that CAT hardware is intelligent, the software uses the RS 232 interface in order to<br />
communicate with CAT hardware, therefore a high priority Windows driver is not necessary.<br />
General Characteristics of CAT<br />
Interface type Intelligent RS232 – CAN Interface<br />
CAN Interfaces 2 * Dual Wire CAN according to GMW3122<br />
1 * Single Wire CAN according to GMW3089<br />
Connectors 25 pin SUB-D RS232 Connector and 9 pin SUB_D special CAN interface<br />
Power Supply 6.5 - 16 V DC power supply via CAN interface connector,<br />
max. 250mA, typical 70mA at 12 V DC with physical interface PCA 82C251<br />
Temperature<br />
Range 0° ... + 70 °C := + 32°... + 158 °F<br />
44
LED Interpretation<br />
Normal States:<br />
1) Power-On = red.<br />
Default after hardware reset.<br />
2) Firmware-Download = green.<br />
The 1st part of the firmware loader switches the LED to green.<br />
3) Normal operation OFFLINE = blinking 2 times: red, green, pause.<br />
Normally it blinks 2 times, that means all is ok.<br />
The 1st blink shows the OFFLINE state = red or the ONLINE state = green.<br />
4) Normal operation ONLINE = blinking 2 times: green, green, pause.<br />
Normally it blinks 2 times, that means all is ok.<br />
The 1st blink shows the OFFLINE state = red or the ONLINE state = green.<br />
5) Block-transfer errors while receiving commands on the RS232<br />
= blinking 4 times: red|green, green, green, green, pause.<br />
The RS232 reception module has detected problems with the RS232-block-transfer and waits for a transfer<br />
pause to reinitialize his buffers.<br />
6) Normal operation (after RS232-errors) = blinking 3 times: red|green, green, green, pause.<br />
After detecting RS232-block-transfer-errors and buffer re-initialization it is back to normal operation. It<br />
never goes back to blinking 2 times.<br />
Special States:<br />
7) Firmware-Initialization = red for 20ms, green for 20ms.<br />
The short red-green makes CAT-firmware in the first part of the initialization. It shows that the firmware<br />
now starts.<br />
8) Internal error<br />
Any other blink code indicates an internal error.<br />
In this case please note the blink code you see and send a short description about this to <strong>I+ME</strong> <strong>ACTIA</strong>.<br />
To: info@ime-actia.de<br />
<strong>I+ME</strong> <strong>ACTIA</strong> appreciates support.<br />

Getting Started<br />
46
Basic Steps<br />
After successful installation there are a few basic steps required to work with CAT:<br />
1) A session has to be created (See Create a new Session ) or an existing one has to be opened (See Open a<br />
Session ).<br />
2) The Baudrate has to be chosen in accordance to the CAN system you want to analyze. See CAN Setup .<br />
Now CAT is ready to go Online. The CAN traffic is displayed only in the status bar.<br />
CAT LED displays being in Online State by blinking 2 times: green, green, pause. Additionally<br />
"Online" is added to the capture of the main application window.<br />
3) Go Offline and Upload the buffer .<br />
4) The Trace List View in Offline Analyzer Mode allows reviewing the buffer content.<br />
CAT LED displays the Offline State by blinking 2 times: red, green, pause. Additionally "Online" is<br />
removed from the capture of the main application window.<br />
To get frame and signal information already Online the following steps should be taken.<br />
5) A database and a vehicle should be selected to choose the "car" to be analyzed. If no database, vehicle and<br />
ECU exist the user may define them. (See Database , Vehicle and ECU)<br />
6) Select frames and signals to be displayed in the Frame List and Signal List. If no frames and signals exist<br />
the user may define them. (See Frame and Signal)<br />

File Management<br />
54
Session Management<br />
The following is highly recommended to be done only by experienced PC users.<br />
All Session related data are stored in session folders named S# (S1, S2, ...). These folders are located in<br />
the folder "CAT_Destination_Folder"\Session (CAT_Destination_Folder is the folder that have been<br />
chosen when installing CAT).<br />
S# in brackets is written in the title bar behind the name given to the session.<br />
Use the standard file managing programs (like Explorer or File Manager) to copy, rename or even<br />
delete these folders.<br />
Copy sessions from one platform to another<br />
- Copy always the complete S# folder.<br />
Tip: Directly after copying, before pasting the folder into the target platform, it is recommended to<br />
rename it. Do not use any S# as name but e.g. user initials and date. Then paste it into the folder<br />
\Session of the target system and may keep an additional backup.<br />
- Check the target platform for an unused S# name and rename the folder into this unused S# name.<br />
- Start CAT on the target system and open the session. Open Database Configuration and select the database<br />
the session originally was linked to.<br />
Note: In the session the link to a Db# (Database) Folder e.g. Db2 is stored. But on the target platform<br />
the database you want to link to might be stored in another Db# folder e.g. Db4, or even does not exist<br />
on the target platform.<br />
- If the database does not exist on the target system copy it from the platform. (See Database Management .)<br />
55
Session Template<br />
The following is highly recommended to be done only by experienced PC<br />
users.<br />
When creating a new session CAT automatically uses the settings of the session template as default<br />
values for the new session. Depending on the PC system these default values may not fit totally the<br />
requirements.<br />
To create the own session template do the following steps:<br />
- Setup a session corresponding to the PC system and general needs:<br />
- link to a database,<br />
- set the layout for the graphical user interface (e.g. windows arrangements),<br />
- configure the filter, trigger, transmit frames and diagnostics<br />
- setup the system for the buffer usage and for the usually connected CAN bus.<br />
- Look for the S# in brackets that is written in the title bar behind the name given to the session.<br />
Note: All session related data are stored in session folders named S# (S1, S2, ...). These folders are<br />
located in the folder "CAT_Destination_Folder"\Session (CAT_Destination_Folder is the folder that<br />
have been chosen when installing CAT).<br />
- Copy the content of this S# folder into the folder ...\Session\Template, especially the files session.cfg and<br />
session.wsp.<br />
Use the standard file managing programs (like Explorer or File Manager) to copy this files.<br />
The next time when creating a session, the done settings will be the default values.<br />
56
Database Management<br />
The following is highly recommended to be done only by experienced PC users.<br />
All Database related data are stored in database folders named Db# (Db1, Db2, ...). These folders are<br />
located in the folder "CAT_Destination_Folder"\Data (CAT_Destination_Folder is the folder that have<br />
been chosen when installing CAT).<br />
Db# in brackets is written in the title bar behind the name given to the database (when a database has<br />
been chosen in the session).<br />
Use the standard file managing programs (like Explorer or File Manager) to copy, rename or even<br />
delete these folders.<br />
Copy databases from one platform to another<br />
- Copy always the complete Db# folder.<br />
Tip: Directly after copying, before pasting the folder into the target platform, it is recommended to<br />
rename it. Do not use any Db# as name but e.g. user initials and date. Then paste it into the folder \Data<br />
of the target system and may keep an additional backup.<br />
- Check the target platform for an unused Db# name and rename your folder into this unused Db# name.<br />
Now there is access to this database independent from the session that might be open or being created.<br />
57
Database Template<br />
The following is highly recommended to be done only by experienced PC users.<br />
When creating a new database CAT automatically uses the settings of the database template as default<br />
values for the new database. Vehicles, ECUs, Frame and Signals are linked to the Database as well as<br />
Diagnostic relevant Data. But the original delivery software of CAT contains no default settings cause<br />
these are mostly company and test bench specific data.<br />
To create the own database template do the following steps:<br />
- Use an existing database or<br />
- Setup a database corresponding to general needs:<br />
- Create a database<br />
- Create vehicles that shall be defined as default.<br />
- Setup ECUs corresponding to the general diagnostic needs of the vehicles:<br />
- define DPIDs and DPID signals,<br />
- setup DIDs,<br />
- define special DTCs,<br />
- setup the FSA List,<br />
- and define CPIDs.<br />
- Create Frames linked to the ECUs that shall be defined as default.<br />
- Create Signals linked to the Frames that shall be defined as default.<br />
- Look for the Db# in brackets that are written in the title bar behind the name given to the database.<br />
Note: All database related data are stored in database folders named Db# (Db1, Db2, ...). These<br />
folders are located in the folder "CAT_Destination_Folder"\Data (CAT_Destination_Folder is the<br />
folder that has been chosen when installing CAT).<br />
- Copy the content of this Db# folder into the folder ...\Data\Temp_db.<br />
Use the standard file managing programs (like Explorer or File Manager) to copy this files.<br />
The next time, when creating a database the done settings will be the default values.<br />
58
ECU Template<br />
The following is highly recommended to be done only by experienced PC users.<br />
When creating a new ECU, CAT automatically uses the settings of the ECU template as default values<br />
for the new ECU. Frames and Signal Definitions are linked to the ECU as well as Diagnostic relevant<br />
Data. But the original delivery software of CAT contains no or only a minimum of default settings<br />
cause these are mostly company and vehicle specific data.<br />
To create the own ECU template do the following steps:<br />
- Create a new vehicle in a database of the choice.<br />
- Setup an ECU corresponding to the general diagnostic needs of the vehicles:<br />
- define DPIDs and DPID signals,<br />
- setup DIDs,<br />
- define special DTCs,<br />
- setup the FSA List,<br />
- and define CPIDs.<br />
- Create Frames linked to the ECU that shall be defined as default.<br />
- Create Signals linked to the Frames that shall be defined as default.<br />
- Look for the Db# and V# in brackets that are written in the title bar behind the names given to the database<br />
and vehicle.<br />
Note: All Database related data are stored in Database folders named Db# (Db1, Db2, ...). These<br />
folders are located in the folder "CAT_Destination_Folder"\Data\(CAT_Destination_Folder is the<br />
folder that has been chosen when installing CAT. These folder again contain V# folder storing vehicle<br />
related data and contain also ECU# data.<br />
- Copy the content of the ECU1 folder located in "CAT_Destination_Folder"\Data\Db#\V# (# corresponding<br />
to the entries in the title bar) into the folder ...\Data\Temp_ecu, especially the folders Diagnost and<br />
Standard.<br />
Use the standard file managing programs (like Explorer or File Manager) to copy these folders.<br />
The next time, when creating an ECU the done settings will be the default values.<br />
59
CAT Diagnostic Setup<br />
Attention: It is highly recommended not to manipulate any files of CAT software e.g. by the use of an editor.<br />
The following is highly recommended to be done only by experienced PC users.<br />
Professional users of the diagnostic features of CAT may need to change the diagnostic parameters<br />
defining the handling of diagnostic frames. Therefore an editor has to be used to change the default<br />
settings in CAT.INI file.<br />
The file CAT.INI is located in the folder "CAT_Destination_Folder"\BIN. (CAT_Destination_Folder is<br />
the folder that have been chosen when installing CAT)<br />
Block Size<br />
The PCI (Protocol Control Interface) parameter RespFlowCtrl_Bsmax (is set to 5 in sample above).<br />
The BS (Block Size) defines the maximum number of frames which can be send before another flow<br />
control frame has to be sent.<br />
Separation Time<br />
The PCI (Protocol Control Interface) parameter RespFlowCtrl_STmin (is set to 100 ms in sample<br />
above). The ST (Separation Time) defines the minimum amount of time in ms that must be between<br />
consecutive frame transmissions of a multi frame message.<br />
Padding<br />
The PCI (Protocol Control Interface) parameters PaddingSWC, PaddingMS, PaddingHS (all are set<br />
to 0 in sample above meaning No Padding). Padding means to fill up the Data Byte Field of the CAN<br />
Frames with 0's, so that the frames always contain 8 Data Bytes.<br />
Set parameter PaddingSWC to 1 to have padding for the Single Wire CAN (SWC), when Single Wire<br />
CAN has been chosen as physical layer in the CAN Setup .<br />
Set parameter PaddingMS to 1 to have padding for the Dual Wire CAN Mid Speed (MS), when Dual<br />
Wire CAN Mid Speed has been chosen as physical layer in the CAN Setup .<br />
Set parameter PaddingHS to 1 to have padding for the Dual Wire CAN High Speed (HS), when Dual<br />
Wire CAN High Speed has been chosen as physical layer in the CAN Setup .<br />
Note: Padding -when activated- is only done for the frames send out by diagnostic services but not<br />
for frames set up in the Transmission table.<br />
60
Offline CAN Acknowledge<br />
The Firmware parameter OfflineWithCANBusOn (is set to 1 in sample above meaning activated).<br />
CAT is able to acknowledge CAN traffic even when being Offline respectively Diagnostic Offline. This<br />
is especially then useful when CAT communicates only to one single ECU (CAN node).<br />
This behavior can be switched off to have no impact to a CAN network when CAT is Offline.<br />
Set parameter OfflineWithCANBusOn to 1 to have CAN acknowledgement even in (Diagnostic)<br />
Offline mode.<br />
Set parameter OfflineWithCANBusOn to 0 to have no CAN acknowledgement in (Diagnostic)<br />
Offline.<br />
61
Diagnostic Data by ID Edit<br />
The following is highly recommended to be done only by experienced PC<br />
and CAT users.<br />
Professional users of the diagnostic features of CAT may need to read out the content of pre-defined<br />
ECU data referenced by a Data Identifier (DID) or to write these data into the ECU.<br />
To change especially long data (up to 128 Byte) CAT allows to store the data and to import them again.<br />
The stored data might be manipulated before they are imported and written into the ECU. Therefore an<br />
editor could be used. See Export Read Data by ID for details about the location of the data file.<br />
Change only the hexadecimal byte values as required. Do not change the general order of the values.<br />

system. A warning appears if the file name already exists and asked if he/she want to overwrite it.<br />
Using Excel to review the file the user is allowed to use all the typical Excel features to analyze even<br />
the content of large tables.<br />
72
Export Read Data by ID<br />
The diagnostic service Read Data by Identifier allows to read the content of pre-defined ECU data<br />
referenced by a Data Identifier (DID) (e.g.: the VIN Vehicle Identification Number). The Diagnostic<br />
Output window allows reviewing the diagnostic buffer content including an interpretation of these data.<br />
To store this data activate the window below by using the assigned Session Menu item.<br />
Note: The command Export Read Data by ID gets enabled when the first response frame - containing<br />
the first part of the ECU data – is in the first line of the buffer review window Diagnostic Output. (In<br />
this case, this frame is displayed in the status bar too.)<br />
Tip: Use the Find it feature to find the first response frame ( 3 rd data byte must be 5A).<br />
The default settings of CAT propose to store the logged content as data.s1a (Service 1A file) using the<br />
s#[CAT internal session number] folder as destination folder.<br />
The user is free to change name and destination according to the PC system and used operating system.<br />
There will be a warning if the file name already exists asking if it shall be overwritten.<br />
Experienced user may manipulate the stored data. (See Diagnostic Data by ID Edit for details.)<br />
The stored data can be imported again when using the diagnostic service Write Data by Identifier .<br />
73

Data Byte/Bit Presentation on the CAN Bus<br />
The samples below depicts how to send data bytes within a CAN frame.<br />
Condition: Data byte 1 of the frame below will be sent out first to the bus.<br />
- 3 signals in bytes 2 and 3 16 bits total which start in byte 2 bit 7<br />
As shown there could be 3 different signals embedded in bytes 2 and 3. For presentation on the bus the important<br />
thing is byte 2 bit 7 is sent first and byte 3 bit 0 is sent last. The location of the signals in the bytes is only important for<br />
encoding/decoding signals of frames (see below).<br />
- A 13 bit unsigned integer which starts in byte 2 bit 7<br />
- A 10 bit unsigned integer which starts in byte 2 bit 4<br />
- A 20 bit unsigned integer which starts in byte 2 bit 6<br />

Boolean<br />
CAT allows the user to edit or remove already existing Signals assigned to Frames. The user can also<br />
create new Signals using CAT.<br />
CAT can recognize eight different types of signals and allows other different formats. To edit or create<br />
a Boolean Signal open the Signal Definition window shown below.<br />
Note: If you edit a diagnostic signal assigned to a DPID you see<br />
DPID: instead of Frame: and Byte is default '1'.<br />
Format<br />
A Boolean Signal may have the format Bitmap or Bool. If the format Bitmap is chosen an interpreted<br />
value can be defined in a Bitmap Definition Table .<br />
Position in the Frame<br />
Byte: Describes which Data Byte of the frame is the first one used for this signal. (Starting Byte) Bytes are<br />
counted upwards:<br />
Byte 0 means the signal could be maximal 8 Byte long<br />
Byte 7 would mean that the signal must fit into this single (last) Byte.<br />
Bit: Describes which Bit of the chosen Data Byte is the first one used for this signal. (Starting Bit) Bits are<br />
counted downwards:<br />
Bit 7 means the complete 8 Bits (7 – 0) of the chosen Byte will be used.<br />
Bit 0 would mean to use only Bit 0 of the Byte and then to use Bit 7, 6, ... of the following Byte.<br />
Length: Describes the absolute Length of the signal.<br />
For a Boolean signal the length is always only one Bit.<br />
See also Data Byte/Bit presentation on the CAN bus.<br />

Transmit Definition<br />
After choosing a Transmit frame in the Transmit List and clicking the Assign button the user reaches<br />
the Transmit Definition window shown below. Here the frame and conditions for transmitting can be<br />
setup.<br />
If frames shall be transmitted that are already defined in the "car" system that shall be analyzed, the user<br />
can select a frame here by choosing the assigned ECU and then the frame. The frame ID, format,<br />
number of data bytes and the default data will be implemented automatically. Then the user will only<br />
have to define the type of transmission and in case of periodic transmission the rate. Nevertheless the<br />
user can modify the automatic implemented frame corresponding values.<br />
Key: Shows the hot key that is assigned to this Transmission frame. Depends on the line that has been<br />
chosen in the Transmit List.<br />
Database: Shows the database the user is working with. Only predefined frames from this database can be<br />
chosen.<br />
Vehicle: Shows the vehicle the user is working with. Only predefined frames from this vehicle can be<br />
chosen.<br />
ECU: Here the ECU that the predefined frame is assigned to can be chosen.<br />
Frame: Here a predefined frame of the database can be chosen.<br />
Otherwise or even if the user has chosen a predefined frame one can edit another name for the transmission frame.<br />
These can be:<br />
a) the name of a predefined frame that has been chosen from the database by selecting the ECU before.<br />
b) the edited name of a predefined frame. E.g. when the assigned data have been edited too.<br />
c) a new name that shall be used for the new defined transmission frame.<br />
In any case the name in this field will be shown as Transmission Name in the Transmission List.<br />
Note: Editing a frame or defining a new frame here has no influence on the Frames<br />
listed in the database!<br />

Trigger<br />
CAT allows defining a Trigger Event based on Frame Identifier and Data. This Trigger is used to set a flag into the<br />
logged buffer and to stop the logging of data. Therefore the user can define by Pre/ Post Trigger how many frames<br />
shall be stored before and after the trigger event occurs.<br />
The feature Time Out Trigger allows to trigger on the lacking of a frame. To use a frame from the database there is an<br />
easy access button to the frame list. (See Trigger on existing Frames)<br />
Choose menu item Configurations | Trigger from the main window to open the Trigger<br />
Configuration... window shown above.<br />
Enable Trigger: Click into this box and get it marked to enable triggering on the defined conditions. Otherwise the<br />
occurrence of a defined frame will have no influence to the logging process at all.<br />
Note: Enable trigger has to be marked to enable the input or edit from all other<br />
input fields in this dialog.<br />
The trigger sign in the status bar becomes yellow when Trigger is enabled.<br />
Use Frame List : Click this button to access the Frame List allowing choosing one or more predefined Frame. Then<br />
the frame ID, format, number of data bytes and the default data will be implemented automatically in order to create a<br />
trigger condition.<br />
Format: Choose standard (STD 11bit Identifier) or extended (XTD 29bit Identifier) format.<br />
Number<br />
of Data Bytes: Choose the number of data bytes that the trigger condition to be triggered on must have.<br />
Tip: Input "0" to trigger only on the Identifier. The Data Bytes will not be<br />
considered as trigger condition.<br />
Note: If a frame contains more data bytes then required it still is a trigger condition<br />
as long as the data bytes, which are required, fulfil the Data Byte Trigger conditions<br />
described below.<br />
123
Example: Trigger conditions are ID = 7XX, Number of Trigger Data Bytes = 1, Data<br />
Byte 0 = $BB then the frame ID $7FF and Data BB BB BB will pass the filter.<br />
Identifier: Insert Frame Identifier to be triggered on at the Bit level. Click directly in the boxes showing the binary<br />
values of the ID Bits. The value changes with each click, from X to 0 to 1.<br />
Identifier HEX: Insert Frame Identifiers to be triggered on at the Hex level. An X is defined as all 4 assigned Bits<br />
are don't care bits.<br />
Data Byte 0 – 7: Insert Data Bytes to be triggered on at the Bit level. Click directly into the boxes showing the<br />
binary values of the Data Bits. The value changes by each click, from X to 0 to 1.<br />
Data Byte HEX: Insert Data Bytes to be triggered on at the Hex level. An X is defined as all assigned 4 Bits are<br />
don't care bits.<br />
Scrollbar: Select "" to define a trigger event if a received data byte is bigger than the defined hexadecimal value.<br />
Note: Selection is only enabled when a real hexadecimal value is put in. If Data<br />
Byte HEX field contains any X as don't care this scrollbar is disabled.<br />
Pre/Post<br />
Trigger Enable: Click in this box to mark it. This will enable the Pre- and Post Trigger. This feature controls the<br />
normal buffer content.<br />
Frames as fit into the defined Pre Trigger buffer size will be stored in the normal buffer before the trigger event occurs.<br />
The logging of frames into the buffer will stop automatically as soon as the defined Post Trigger buffer size is reached.<br />
Pre Trigger size: Select the size of the normal buffer in % that shall be used to store the logged data before the<br />
trigger event occurs.<br />
Note: The size of the normal buffer is configurable by the user (see Buffer Setup ).<br />
Only after enabling the Pre/Post Trigger any selection will be possible.<br />
Post Trigger size: Select the size of the normal buffer that is used to store the logged data after the trigger event<br />
occurs.<br />
Note: The size of the normal buffer is configurable by the user (see Buffer Setup ).<br />
Only after enabling the Pre/Post Trigger any selection will be possible.<br />
Time Out<br />
Trigger Enable: Click in this box to mark it. This will enable the Time Out Trigger.<br />
Disabled: The trigger event is the occurrence of the above defined trigger condition on the bus.<br />
Enabled: After receiving the above defined trigger condition for the first time CAT looks for a periodic receiving of this<br />
trigger condition. The trigger event is the missing of the trigger condition on the bus for the defined time.<br />
Time [ms]: Input the time during a frame that has to occur on the bus, otherwise it is the trigger event.<br />
Click on OK to acknowledge the input.<br />
124<br />
Note: Only after enabling the Time Out Trigger any input will be possible.
Trigger on existing Frames<br />
When the user is defining the trigger condition in the Trigger Configuration window he/she can activate<br />
the Frame List for the Trigger Configuration window shown below.<br />
If the user wants to use frames that are already defined in the "car" system that shall be analyzed, the<br />
user may select a frame here by choosing the assigned ECU and then the frame. The frame ID, format,<br />
number of data bytes and the default data will be implemented automatically in the trigger<br />
configuration. The user still can modify the automatic implemented frame corresponding values.<br />
Database: Shows the database the user is working with. Only predefined frames from this database can be<br />
chosen.<br />
Vehicle: Shows the vehicle the user is working with. Only predefined frames from this vehicle can be chosen.<br />
ECU: Here the user may choose the ECU the predefined frame is assigned to.<br />
Frame: Here the user may choose a predefined frame from the database. The data assigned to this frame will occur<br />
in the Trigger Configuration window.<br />
125
Diagnostics<br />
CAT allows setup and addressing predefined diagnostic services. In the Main Diagnostic Setup window<br />
it is possible to define for each service if CAT shall correspond to single nodes (Physical Addressing) or<br />
to multi nodes (Functional Addressing). Therefore the Diagnostic CAN Ids for the addressing can be set<br />
up.<br />
Some services require a preliminary and then continuously sending of the service Tester Present. CAT<br />
allows defining for each supported service this behavior individually.<br />
Additionally to this and the addressing of the services there is access to the setup of the sub-functions<br />
and parameter of the services. There is direct access as well to the DID, DTC and FSA Definition.<br />
Beside the setup for the launching of the services the user can also define which service and related<br />
messages shall be displayed in the Diagnostic Online View and the conditions to launch this service<br />
when being Diagnostic Online.<br />
Choose menu item Configurations | Diagnostics from the main window to open the Main Diagnostic<br />
Setup... window shown below.<br />
Note: The configuration / setup of the Main Diagnostic Launch Table is even possible when being<br />
online already by opening the Main Diagnostic Setup dialog under Configurations.<br />
Functional Addressing<br />
Put in the Diagnostic CAN ID corresponding to the Identifier Type to be used. (E.g. $101 for All Node<br />
request.) Then select the Extended Address (Ext. Addr.) hexadecimal value corresponding to the<br />
Functional System you wish to communicate with. (E.g. $FE for All Functions.)<br />
The name of the chosen functional system is displayed above 'CAN ID:'.<br />
Assign the services to be functional addressed by clicking the left radio button at the end of the line of<br />
the service name.<br />
126
Physical Addressing<br />
Put in the Diagnostic CAN ID ($24X) corresponding to the USDT request to be sent. (Here $241 has<br />
been assigned to the ECU named ECU.)<br />
The name of the chosen ECU is displayed above 'CAN ID:', if the Diagnostic CAN ID index (here 41)<br />
has been assigned to an ECU in the database. See ECU for details. Otherwise 'unknown' is displayed.<br />
Assign the services to be physical addressed by clicking the right radio button at the end of the line of<br />
the service name.<br />
Note: It is not required that the ECU corresponding to the CAN ID exists in the chosen database as<br />
long as a real node within this Diagnostic CAN ID is part of the CAN system.<br />
Tester Present<br />
Assign the services to be send out with preliminary and continuously send out of Tester Present by<br />
marking the box in front of the line of the service name.<br />
Note: GMLAN requires for some diagnostic services that right before they are sent out by a<br />
diagnostic tool the service Tester Present has to be sent preliminary and then continuously at least every<br />
5 seconds. For the services that require this behavior the boxes are marked with a "*".<br />
Service – Id – sub-function<br />
This table gives an overview about all the diagnostic services and their ID's that are supported by CAT.<br />
Additionally the sub-function ID's, corresponding to the Setup of the service, are displayed (see below).<br />

Diagnostic Services<br />
129
Read Trouble Codes<br />
This service ($A9) allows a tester to read the status of node-resident Diagnostic Trouble Code (DTC)<br />
information from any controller, or group of controllers within a vehicle. This service allows the tester<br />
to do the following:<br />
- Retrieve the status of a specific DTC and FaultType combination.<br />
- Retrieve the list of DTCs that match a tester defined DTC status mask.<br />
- Enable a node resident algorithm, which periodically calculates the number of DTCs that match a tester<br />
defined DTC status mask. The ECU shall send a response message each time the calculation yields a<br />
different result than the one calculated the previous time.<br />
Depending on the required action the service has to be configured. Therefor the Setup button in the<br />
Main Diagnostic Setup window could activate the dialog box shown below.<br />
$80 Read Status Of DTC By DTC Number<br />
To retrieve the status of a specific DTC and DTC Fault Type Byte (symptom) combination, setup the<br />
sub-parameter $80 Read Status Of DTC By DTC Number. The user needs to put in the DTC number<br />
(DTC High Byte and DTC Low Byte) and the DTC Failure Type Byte. Acknowledge the settings by<br />
OK.<br />
$81 Read Status Of DTC By Status Mask<br />
To retrieve a list of DTC numbers and DTC Fault Types, which satisfy the defined status mask, setup<br />
the sub-parameter byte $81 Read Status Of DTC By Status Mask. The user needs to select a mask. By<br />
click on Select Mask the user opens the dialog shown below or the user may put in directly a one-byte<br />
hexadecimal value that defines the mask.<br />
Note: CAT uses the End Of DTC Report message to determine when all UUDT responses to a level<br />
$81 request have been sent. For a given node, transmitting another $Level $81 request prior to receiving<br />
the endOfDTCReport message may result in undefined operation.<br />
$82 Send On Change DTC Count<br />
To enable a node-resident DTC count algorithm that periodically calculates the number of DTCs that<br />
match a defined DTC status mask, setup the sub-parameter $82 Send On Change DTC Count. The user<br />
130
needs to select a mask. By click on Select Mask the dialog shown below appears or the user may put in<br />
directly a one-byte hexadecimal value that defines the mask.<br />
Note: The send-on-change status mask and DTC count information are lost upon a $3E time-out,<br />
after a $20 service request, or after power is cycled.<br />
The DTC Status Mask contains 8 DTC status bits. To check for a logical '1', a set bit the user has to<br />
mark it in the list. In the sample above all bits are marked so the DTC Status Mask hexadecimal value is<br />
a 'FF'.<br />
Warning Indicator Requested State<br />
Warning output status reports the status of any warning indicators associated with a particular DTC.<br />
Warning outputs may consist of indicator lamp(s), displayed text information, etc.<br />
- Logical '1' = Warning indicator requested to be ON.<br />
- Logical '0' = Warning indicator not requested to be ON.<br />
Current DTC Since Power Up<br />
This indicates that a DTC became current during the current ignition/power cycle.<br />
- Logical '1' = DTC became current this power up.<br />
- Logical '0' = DTC did not become current this power up.<br />
Test Not Passed Since Current Power Up<br />
This indicates a logical '0' once the test indicates a passed result. A logical '1' indicates that the test has<br />
not run, or that the test has run and failed.<br />
- Logical '1' = Test not passed since current power up.<br />
- Logical '0' = Test passed since current power up.<br />
Note: This flag is reset to a logical '1' with each ignition cycle.<br />
131
History DTC<br />
A history DTC indicates that a "current" DTC status has met sufficient criteria for storing a code into<br />
long-term memory.<br />
- Logical '1' = DTC is history.<br />
- Logical '0' = DTC is not history.<br />
Test Failed Since DTC Cleared<br />
This indicates that a current DTC is or has been set sometime since the last time the DTC status was<br />
reset.<br />
- Logical '1' = Test failed since DTCs have been cleared.<br />
- Logical '0' = Test not failed since DTCs have been cleared.<br />
Test Not Passed Since DTC Cleared<br />
This indicates a logical '0' once the test indicates a passed result. A logical '1' indicates that the test has<br />
not run, or that the test has run and failed.<br />
- Logical '1' = Test not passed since DTC cleared.<br />
- Logical '0' = Test passed since DTC cleared.<br />
Current DTC<br />
A current DTC indicates that test conditions have been met and the test results show that a fault is<br />
currently present. This flag indicates the results of the last diagnostic test performed.<br />
- Logical '1' = DTC is current.<br />
- Logical '0' = DTC is not current.<br />
DTC Supported By Calibration<br />
This indicates that a node will trigger the test associated with a particular DTC as soon as the criteria for<br />
performing the test have been satisfied.<br />
- Logical '1' = DTC supported<br />
- Logical '0' = DTC not supported<br />
132
Read Failure Record Identifier<br />
The service Read Failure Record Data ($12) is used to obtain failure record information that was<br />
captured due to a fault detected within the node.<br />
CAT provides two already predefined setup levels of the Read Failure Record Data service:<br />
- The Read Failure Record Identifiers (sub-function parameter = $01),<br />
- The Read Failure Record Parameters (sub-function parameter = $02).<br />
Read Failure Record Identifiers (sub-function parameter = $01) allows CAT to obtain the information<br />
necessary to send a request to retrieve the data parameters associated with a specific failure record<br />
stored in a node.<br />
Note: This level is only used to obtain the failureRecordDataStructureIdentifier parameter and the<br />
failure record identifiers. The data bytes contained within a particular failure record are retrieved with<br />
the Read Failure Record Parameters ($02) level.<br />
There are no additional setups needed / allowed for the Read Failure Record Identifiers level.<br />
133
Read Failure Record Parameters<br />
The service Read Failure Record Data ($12) is used to obtain failure record information that was<br />
captured due to a fault detected within the node.<br />
CAT provides two already predefined setup levels of the Read Failure Record Data service:<br />
- The Read Failure Record Identifiers (sub-function parameter = $01),<br />
- The Read Failure Record Parameters (sub-function parameter = $02).<br />
Read Failure Record Parameters (sub-function parameter = $02) allows CAT to retrieve the data<br />
parameters in the failure record associated with the failure record identifier. Failure record data<br />
parameters consist of ECU inputs, outputs, and calculated values, which provide information about the<br />
operating conditions of the vehicle at the time the DTC, is logged.<br />
To read out the parameters of the failure record the Failure Record Identifier has to be configured. The<br />
Setup button in the Main Diagnostic Setup window could activate the dialog box shown below.<br />
The Failure Record Identifier consists of 4 bytes, which include the Failure Record Number and the<br />
DTC Identifier (2 byte DTC number + 1 byte DTC fault type).<br />
Note: Valid failure record identifier data values are obtained by CAT from the Read Failure Record<br />
Identifiers ($01) level of this service.<br />
Input the desired Identifier and acknowledge the setup by OK.<br />
134
Clear Trouble Codes<br />
The Clear Trouble Codes service ($04) is used by the tester to clear diagnostic information (Diagnostic<br />
Trouble Codes and assigned data) in one (physical addressed) or multiple (functional addressed) nodes'<br />
memory.<br />
The service Clear Trouble Codes does not need / allow any setup.<br />
See also Diagnostics for information about functional and physical addressing.<br />
135
Read Data by Identifier<br />
The purpose of this service ($1A) is to provide the ability to read the content of pre-defined ECU data<br />
referenced by a Data Identifier (DID) which contains static information such as ECU identification data<br />
or other information which does not require "real-time" updates (e.g.: the VIN Vehicle Identification<br />
Number).<br />
Note: "Real-time" data is intended to be retrieved via the Read Data By Packet Identifier ($AA)<br />
service.<br />
This service has to be send out with exactly one DID, that's information is requested. Depending on the<br />
required information the service has to be configured. The Setup button in the Main Diagnostic Setup<br />
window could activate the dialog box shown below.<br />
The corporate defined DIDs could be selected from the provided list or the hexadecimal value of a user<br />
defined DID might be entered. Acknowledge the setup by OK.<br />
136
Write Data by Identifier<br />
The purpose of this service ($3B) is to provide the ability to change (write/program) the content of predefined<br />
ECU data referenced by a Data Identifier (DID), which contains static information like ECU<br />
identification data, or other information, which does not require "real-time" updates.<br />
This service has to be send out with exactly one DID and the data that shall replace the previously<br />
stored information for this DID. Therefore the Setup button in the Main Diagnostic Setup window could<br />
activate the dialog box shown below.<br />
DID<br />
Only one Data Identifier, which is supported by the ECU, shall be included in the request message.<br />
Corporate defined DIDs could be selected from the provided list or the hexadecimal value of a user<br />
defined DID might be entered.<br />
Data<br />
Input the data that shall be assigned to the DID as hexadecimal values in byte format, divided by<br />
commas as shown above. The number of data bytes is dependant upon the size of the data referenced by<br />
the Data Identifier parameter.<br />
Acknowledge the setup by OK.<br />
Note: This service should be requested using physical addressing. See the Main Diagnostic Setup<br />
window for details about addressing.<br />
137
Import<br />
Use the import button to re-use the data that have been preliminary read out and stored (see Read Data<br />
by ID and Export Read Data by ID ).<br />
The dialog box shown below allows selecting any ECU data that have been stored before as Service 1A<br />
file.<br />
138
Read Data by Packet Identifier<br />
The purpose of the Read Data By Packet Identifier ($AA) service is to allow a tester to request data<br />
packets that contain diagnostic information (e.g. sensor input or output values) which are packaged in a<br />
UUDT diagnostic message format. Each diagnostic data packet includes one byte that contains a Data<br />
Packet Identifier (DPID) number, and 1 to 7 bytes of additional data. The DPID number occupies the<br />
message number byte position of the UUDT diagnostic response message and is used to determine the<br />
data contents of the remaining bytes of the message.<br />
Note: This service is intended to be used to retrieve ECU data, which is most likely changing during<br />
normal operation (e.g. ECU sensor inputs, ECU commanded output states, etc). Static information such<br />
as VIN or Part Numbers should be retrieved via the Read Data By Identifier ($1A) service.<br />
The DPIDs requested via this service can be sent as a one-time response or scheduled periodically. Each<br />
DPID scheduled can be transmitted at one of three predefined periodic rates (slow, medium or fast).<br />
The Read Data By Packet Identifier service request message includes a sub-function parameter and at<br />
least one DPID number when the request is for a one time response (sub-function parameter $01) or<br />
periodic transmission (sub-function parameters $02 through $04). A single request to stop sending one<br />
or multiple periodic DPIDs (sub-function parameter $00) may be sent with or without additional DPID<br />
data.<br />
Depending on the required action the service has to be configured. Therefore the Setup button in the<br />
Main Diagnostic Setup window could activate the dialog box shown below.<br />
Sub Function Parameter<br />
Stop Sending $00<br />
Stops periodic transmission of the DPIDs that have been chosen to be requested.<br />
Send One Response $01<br />
139

Request to schedule DPID(s) in the request at slow periodic rate.<br />
Schedule At Medium Rate<br />
Request to schedule DPID(s) in the request at medium periodic rate.<br />
Schedule At Fast Rate<br />
Request to schedule DPID(s) in the request at fast periodic rate.<br />
DPIDs to be requested<br />
These are the DPID numbers that are requested. The data values identify to the corresponded node<br />
which DPID(s) to transmit or stop transmitting (as indicated by the preceding sub-function parameter<br />
byte).<br />
Selectable DPIDs<br />
These are the DPID numbers that have been defined for the ECU that is addressed to this service. See<br />
Main Diagnostic Setup Window for details about how to choose the ECU and how to address services.<br />
DPID Definition<br />
Use the DPID Definition button to create, edit or remove DPIDs of the DPID List of the chosen ECU.<br />
See DPID List for details how to use it. See Main Diagnostic Setup Window for details about how to<br />
chose the ECU.<br />
140
Read Memory by Address<br />
The purpose of this service ($23) is to retrieve data from a contiguous range of ECU memory addresses.<br />
Depending on the required address range the service has to be configured. Therefore the Setup button in<br />
the Main Diagnostic Setup window could activate the dialog box shown below.<br />
The range of ECU addresses is defined by a three-byte memory starting address parameter and a twobyte<br />
length (memory size) parameter included in the request message.<br />
Input the ECU address as hexadecimal values and the Memory Size as decimal value (up to 65535).<br />
Acknowledge the setup by OK.<br />
141
Device Control<br />
The purpose of the service Device Control ($AE) is to allow CAT to override normal output control<br />
functions in order to verify proper operation of a component or system, or to reset/clear variables used<br />
within normal control algorithms.<br />
Manipulating predefined bits and/or bytes within a message, to indicate to the device which outputs or<br />
control functions the tool wants to override, performs device control. The first data byte (after the<br />
service identifier) of a device control request message is a Control Packet Identifier (CPID). The<br />
remaining 5 bytes are used to provide output control information. However, it is not required that a<br />
CPID contains 5 bytes of control information. CAT will send out only as many data bytes as defined.<br />
CAT allows setup up to 10 CPIDs and the assigned CPID Control Bytes. Therefore the Setup button in<br />
the Main Diagnostic Setup window could activate the dialog box shown below.<br />
Note: This service should only be requested using physical addressing. See the Main Diagnostic<br />
Setup window for details about addressing.<br />
Request to known ECU<br />
If there is an ECU addressed that is contained in the Database, the CPID Table contains the predefined<br />
CPID and Control Data. But CAT allows modifying the existing entries. Put in the required CPID and<br />
control bytes. Use the radio buttons to select the CPIDs that shall be requested. Acknowledge the<br />
settings by OK.<br />
Request to unknown ECU<br />
142
If an ECU has been addressed that is not contained in the Database, CAT allows creating a CPID Table<br />
without the need to create an ECU that would be added to the database. Put in the required CPID and<br />
control bytes. Use the radio buttons to select the CPIDs that shall be requested. Acknowledge the<br />
settings by OK.<br />
143
Device Control Reset<br />
The purpose of the service Device Control ($AE) is to allow CAT to override normal output control<br />
functions in order to verify proper operation of a component or system, or to reset/clear variables used<br />
within normal control algorithms. See Device Control for details about this service.<br />
In generally Device Control Reset is absolutely identical to the service Device Control. Even the same<br />
CPID table as shown below has to be used. But the fact that CAT provides this service twice allows the<br />
user to set up these both in different ways. Meaning the user selects a different CPID (of the max. 10<br />
available) for the Device Control Reset service than for the Device Control service.<br />
This allows the user to launch two different Device Control services without going offline to change the<br />
settings. Especially to Reset the service this feature is needed.<br />
Note: This service should only be requested using physical addressing. See the Main Diagnostic<br />
Setup window for details about addressing.<br />
144
Security Access - request seed<br />
The purpose of the service ($27) Security Access is to provide a way to access data and/or diagnostic<br />
services, which have restricted access for security, emissions, or safety reasons.<br />
The security concept uses a seed and key relationship. The seed and key are each 16-bit numbers (2<br />
byte). The key has to be sent to an ECU to enable ("unlock") Cat's access to specific services. The seed<br />
using an encryption algorithm can derive the key. Therefore an individual seed is stored on each ECU.<br />
CAT provides two already predefined setup levels of the Security Access service:<br />
- The Security Access – request seed (sub-function parameter = $01 or $03),<br />
- The Security Access – send key (sub-function parameter = $02 or $04).<br />
To setup the sub-function parameter to request seed $01 or $03, the Setup button in the Main Diagnostic<br />
Setup window could activate the dialog box shown below.<br />
Sub-function parameter $01 is the request seed level used for ECU programming via the SPS system.<br />
Sub-function parameter $03 is the request seed level for enabling vehicle manufacturing specific device<br />
control restrictions (as opposed to having service device control restrictions enabled).<br />
145
Security access - send key<br />
The purpose of the service ($27) Security Access is to provide a way to access data and/or diagnostic<br />
services, which have restricted access for security, emissions, or safety reasons.<br />
The security concept uses a seed and key relationship. The seed and key are each 16-bit numbers (2<br />
byte). The key has to be sent to an ECU to enable ("unlock") Cat's access to specific services. The seed<br />
using an encryption algorithm can derive the key. Therefor an individual seed is stored on each ECU.<br />
CAT provides two already predefined setup levels of the Security Access service:<br />
- The Security Access – request seed (sub-function parameter = $01 or $03),<br />
- The Security Access – send key (sub-function parameter = $02 or $04).<br />
To setup the sub-function parameter to send key $02 or $04, the Setup button in the Main Diagnostic<br />
Setup window could activate the dialog box shown below.<br />
Sub-function parameter $02 is the send key level used for ECU programming via the SPS system.<br />
Sub-function parameter $04 is the send key level for enabling vehicle manufacturing specific device<br />
control restrictions (as opposed to having service device control restrictions enabled).<br />
146
Tester Present<br />
This service ($3E) is used to indicate to a node (or nodes) that a tester is still connected to the vehicle<br />
and that certain diagnostic services that have been previously activated are to remain active. Some<br />
diagnostic services require that a diagnostic tool send a request for this service ($3E) preliminary and<br />
then periodically in order to keep the functionality of the other service active.<br />
The Tester Present service is activated and transmitted each 2 seconds automatically by CAT, when<br />
defined in the Main Diagnostic Setup. (See Diagnostics .)<br />
The service Tester Present does not need / allow any setup.<br />
Note: Use the service Return to Normal Mode to stop the periodical transmission of the Tester<br />
Present service or go Offline respectively Diagnostic Offline.<br />
147
Initiate Diagnostic Operation<br />
This service ($10) allows the tester to perform the following tasks:<br />
- Disable the setting of all DTCs while the tool continues to perform other diagnostic services.<br />
- Allow ECU DTC algorithms to continue to execute while the Device Control ($AE) service is active.<br />
- Request a gateway ECU to issue a wake up request.<br />
Depending on the required task the Sub Parameters of this service has to be configured. Therefore the<br />
Setup button in the Main Diagnostic Setup window could activate the dialog box shown below.<br />
Choose the desired Sub Parameter and acknowledge the setup with OK.<br />
The service with Sub Parameter $02 (disable all DTCs) disables setting of all DTCs.<br />
The service with Sub Parameter $03 (enable DTCs during device control) allows DTC algorithms to<br />
continue to execute while the DeviceControl ($AE) service is active.<br />
148
Disable Normal Communication<br />
The purpose of this service ($28) is to prevent a device from transmitting or receiving all messages,<br />
which are not the direct result of a diagnostic request. The primary use of the service is to set up a<br />
programming event.<br />
The service Disable Normal Communication does not need / allow any setup.<br />
Note: Use of this service during a programming event should always be targeted to all nodes using<br />
the 'AllNodes' functional diagnostic request CANId ($101) and the "AllNodes" extended address ($FE).<br />
See the Main Diagnostic Setup window for details about addressing.<br />
149
Return to Normal Mode<br />
The purpose of this service ($20) is to return a node or group of nodes to normal mode operation by<br />
canceling all active diagnostic services and resetting normal message communications (if they were<br />
interrupted by a diagnostic operation).<br />
The service Return to Normal Mode does not need / allow any setup.<br />

System Setup<br />
161
CAN Setup<br />
CAT supports normal "Dual Wire" CAN and additionally the Single Wire CAN. For easy Setup of CAT<br />
to the users CAN bus application there are already three physical layers predefined: Single Wire CAN,<br />
Dual Wire CAN (Mid Speed), Dual Wire CAN (High Speed).<br />
The user can configure the Baud Rates for each of the layers as they are in his CAN applications. So the<br />
user can easy change between Mid Speed and High Speed and does not need to define the Baud Rate<br />
each time.<br />
CAT allows the user to determine if CAN messages shall be acknowledged by CAT even if CAT is<br />
Offline or in Diagnostic Offline. See CAT Diagnostic Setup for details how to set up.<br />
For the Single Wire CAN the user can setup the Baud Rates for the Low Speed and the High Speed<br />
mode (used only with the $A5-ProgrammingMode Service). The Baud Rate, defined as Low Speed,<br />
will be used for the "normal" communication. If the CAN system foresees to switch between two<br />
different baud rates the user has to define a High Speed baud rate.<br />
Choose menu item Configurations | CAN Setup from the main window to open the CAN Setup...<br />
window shown above.<br />
Physical Layer:<br />
Click on a radio button to select and mark one of the physical layers.<br />
Baud Rate:<br />
Select a predefined Baud Rate from the List assigned to the chosen physical layer.<br />
BTR 0 + 1:<br />
The Bit Timing Register (BTR) will be calculated and shown depending on the chosen Baud Rate.<br />
Note: These are the BTR for the SJA 1000 CAN Controller used by CAT.<br />
If the Baud Rate of ones CAN System is not listed in any of the Baud Rate Lists of the different layer, the Baud Rate<br />
can be determined by setting the BTR manually.<br />
162
The CAN Setup window above shows how to put in BTR values manually.<br />
Custom:<br />
Click in this box to enable the BTR input fields.<br />
BTR 0 + 1:<br />
Put in the Hex Values for the desired Baud Rate or to adjust the Sample point. The Baud Rate will be<br />
calculated and shown depending on the inputted BTR values.<br />
Note: the user has to put in the BTR values for the SJA 1000 CAN Controller used by CAT.<br />
It is not possible to try out any BTR values and see what<br />
transfer speed you can get! There are too many values that are not possible and can<br />
put the CAN chip in an erratic state. Take only exact calculated values<br />
that take care of the BTR restrictions. See also in the SJA1000 data sheet.<br />
Here are the values that are already predefined (to be selected by Baud Rate):<br />
BTR0 / 1 – Speed [kbps]<br />
40 14 – 1000<br />
80 25 – 800<br />
c0 49 – 500<br />
c1 49 – 250<br />
c3 49 – 125<br />

To upload the buffer<br />
Choose menu item Commands | Upload Buffer or use hot key F8 to start the uploading of the buffer<br />
content to the PC. It is independent if you are in the Offline or Diagnostic Offline mode before.<br />
Note: The Upload process may takes some time (depending logging time and bus traffic).<br />
But you can work on the data during that time. You may even scroll inside the Views.<br />
166
Online Analyzing<br />
Choose menu item Commands | Online to go Online. See Changing CAT Modes for details and how to<br />
leave the Online Mode. The Online Mode of CAT allows visualizing, analyzing and logging the traffic<br />
on the bus.<br />
The Frame and Signal List Views and the Status Bar can be used to visualize the bus traffic. Choose<br />
menu item Windows | to open/ close the windows.<br />
Note: You have to configure the Frame and Signal List before in Offline Mode.<br />
See Offline Setup | Layout Setup for details.<br />
For Analyzing and Visualization the Online Mode offers:<br />
Frame List View<br />
The Frame List displays up to 10 frames but only the frames that are selected to be displayed (see Frame<br />
List Configuration).<br />
Online the most recently acquired frames data will be displayed. The Name, ID and Format will be<br />
displayed as soon as the frame is selected to be displayed.<br />
Signal List View<br />
The Signal List displays up to 20 signals but only the signals that are selected to be displayed (see Signal<br />
List Configuration).<br />
Online the most recently acquired data carried by a frame will be interpreted and displayed. The color of<br />
the characters for the signal value changes from black to red and vice versa each time the same signal is<br />
received again.<br />
Status Bar<br />
The Status Bar displays the most significant data about the CAN bus traffic depending on the mode.<br />
Online the most recently acquired frame and bus data will be displayed.<br />
Being Online the received and transmitted data are logged to the buffer on CAT Hardware. The Buffer<br />
content is first stored only on the Hardware. Only after uploading the buffer there is access to this data<br />
in the Offline respectively Diagnostic Offline Mode.<br />
! If the user disconnects the Hardware from the Power Supply (by disconnecting the CAN<br />
adapter cable) and has not uploaded the buffer the user will loose the logged data!<br />
167
Filtering<br />
CAT allows defining 10 different "Pass Through" Filter based on the Frame Identifier and the Data that<br />
are received. In Offline mode, the 10 filter conditions can be defined and selected to create the<br />
combined filter. (All selected filter conditions are valid; see Filter List and Filter Definition for more<br />
details.)<br />
The selected, combined filter can be activated and deactivated in any mode: Online, Diagnostic Online,<br />
Offline or Diagnostic Offline.<br />
To activate selected Filter<br />
Choose menu item Commands | Filter or use hot key combination CTRL + F to start the Filtering. It is<br />
independent in which mode CAT has been before.<br />
Note: The background color of the Filter sign in the Status Bar becomes yellow indicating an<br />
activated filter.<br />
To deactivate selected Filter<br />
Choose menu item Commands | Filter or use hot key combination CTRL + F to stop the Filtering. It is<br />
independent in which mode CAT has been before.<br />
Note: The background color of the Filter sign in the Status Bar becomes white indicating no<br />
activated filter<br />
Note: The defined filter conditions may cover the defined Trigger conditions so that no Trigger<br />
Frame could pass the filter. In this case you will be warned going online even if you have not activated<br />
the filter.<br />
The filter has no influence on the transmission of frames by CAT himself including the launch of<br />
diagnostic services.<br />
168
Transmitting<br />
CAT allows defining 10 different Transmit Frames based on Frame Identifier and Data. The Transmit<br />
Frames that shall be used have to be defined in Offline mode. Also the Transmission Frames are<br />
assigned to a hot key CTRL 0 – 9 in Offline mode. (See Transmit List and Transmit Definition for more<br />
details.)<br />
The Transmission of the frame can be activated and deactivated only in online mode one by one. The<br />
activation of the transmission of all or groups of the defined Transmission Frames at once is not<br />
possible.<br />
Note: The filter has no influence on the transmission of frames by CAT including the launch of<br />
diagnostic services.<br />
To activate the Transmission of a Frame<br />
By Hot key<br />
Use the assigned hot key combination to transmit the frame. Depending on the defined transmit<br />
conditions the frame will be transmitted once (one shot) or periodically until you deactivate the<br />
transmission.<br />
By Transmit Table<br />
Choose menu item Commands | Transmit to open the Transmit Table shown below. Select a defined<br />
frame by clicking into the list. The Send button gets enabled. Click the Send button to transmit the<br />
frame. Depending on the defined transmit conditions the frame will be transmitted once (one shot) or<br />
periodically until you deactivate the transmission.<br />
Close the table or shift it to the side if it is blocking the view to the Frame or Signal List.<br />
Note: None defined filter has any influence on the transmission of Frames by CAT.<br />
The Transmit Table<br />
The first column describes the hot key the frames are assigned to. The Name of this frame is shown in the next<br />
column. The defined periodic transmission rate respectively 'one shot' is figured out in the last column<br />
To deactivate the Transmission of a Frame<br />
By Hot key<br />
Use the assigned hot key combination to stop the transmission of the frame.<br />
By Transmit Table<br />
169
If Transmit Table is closed choose menu item Commands | Transmit to open the Transmit Table shown<br />
below.<br />
Select a transmitting frame by clicking into the list.<br />
The Stop button gets enabled respectively the Send button turns into a stop button. Click the Stop button<br />
to stop the transmission of the frame.<br />
Note: Activated Transmit Frames are mark in the table by a * at the end of the line. (See below)<br />
170
Triggering<br />
CAT allows defining a Trigger Event based on Frame Identifier and Data. This Trigger is used to set a<br />
mark into the logged buffer and to stop the logging of data. Therefore it can be defined by Pre/ Post<br />
Trigger how many frames shall be stored before and after the trigger event occurs.<br />
The feature Time Out Trigger allows to trigger on the lacking of a frame. To use a frame of the database<br />
there is an easy access button to the frame list. (See Trigger and Trigger on existing Frames for more<br />
details.)<br />
Triggering is enabled and the trigger conditions are defined in Offline mode. If the trigger is enabled the<br />
Trigger is activated by the data on the bus or the Trigger Event can be activated manually (CTRL +T).<br />
Note: The defined filter conditions may cover the defined Trigger conditions so that no Trigger<br />
Frame could pass the filter. In this case you will be warned going online even if you did not activate the<br />
filter.<br />
Trigger Event by Data on the bus<br />
Depending on the defined Trigger conditions a Trigger Event occurs:<br />
Without<br />
Time Out Trigger: When the defined Frame and Data are received<br />
With<br />
Time Out Trigger: When the defined Frame and Data are received once and then are not received again periodically<br />
in the defined maximal periodic time. The missing of this Frame and Data for exactly this defined time is the trigger<br />
event.<br />
Note: The Trigger Event can be activated also by the data you are transmitting to the bus by CAT.<br />
Transmitted Frames will not be filtered.<br />
When the Trigger event occurs the Trigger sign in the Status Bar switches to red.<br />
Trigger Event by manual input<br />
Choose menu item Commands | Trigger or press the hot key combination CTRL + T to enforce a<br />
Trigger Event even if the Trigger is not enabled.<br />
Note: When the Trigger event occurs the Trigger sign in the Status Bar switches to red.<br />
Stopping the Online Mode<br />
Depending on the defined Trigger conditions (Pre/Post Trigger) the Online mode stops immediately<br />
when the Trigger Event occurs. CAT switches to the Offline Mode and a message box informs the user<br />
that Trigger stops the Online Mode. After acknowledge of this message the Upload of the buffer content<br />
starts automatically.<br />
If Pre/Post Trigger is defined CAT stays in the Online Mode logging as long data as the amount of<br />
frames is reached filling up the defined post trigger buffer size. Then the Online mode stops and CAT<br />
switches to the Offline Mode and a message box informs the user that Trigger stops the Online Mode.<br />
After acknowledge of this message the Upload of the buffer content starts automatically.<br />
For more details about the Trigger conditions and defining them see also Trigger Definition .<br />

Launch Diagnostic Services<br />
Choose menu item Commands | Diagnostics to open the Main Diagnostic Launch Table shown below.<br />
As an Online Control window there is no need to close the window to work on. Just shift the table aside<br />
to have a free view on the main application and shift it back when it is needed again.<br />
This Table allows launching the services in accordance to the settings that have been done offline<br />
before. See Diagnostics for details about the setup of the Main Diagnostic Launch Table.<br />
Note: The configuration / setup of the Main Diagnostic Launch Table is even possible when being<br />
online already by opening the Main Diagnostic Setup dialog under Configurations.<br />
To transmit a CAN Frame representing a service, the service has to be selected first in the list and then<br />
the launch button has to be clicked.<br />
Note: All diagnostic services are sent out as USDT (Unacknowledged Segmented Data Transfer)<br />
requests.<br />
Note: The filter has no influence on the transmission of frames by CAT including the launch of<br />
diagnostic services.<br />
According to GMLAN the following services require a tester present service. For these services the<br />
boxes in the Tester Present column on the left side of the dialog are marked by a *.<br />
- - ($AA) Read Data by Packet Identifier,<br />
- - ($AE) Device Control.<br />
- - ($27) Security Access,<br />
- - ($10) Initiate Diagnostic Operation,<br />
- - ($28) Disable Normal Communication,<br />
172
CAT sends out the tester present service automatically just before the wished service and then every 2<br />
seconds (may vary, depending on the bus traffic) when Tester Present box has been marked.<br />
The tester present service is sent until either the Service Return to Normal Mode is sent or when<br />
changing into Offline respectively Diagnostic Offline Mode.<br />
173
Diagnostic Online Mode<br />
174
Diagnostic Online Analyzing<br />
Choose menu item Commands | Diagnostic Online to go Diagnostic Online. See Changing CAT Modes<br />
for details and how to leave the Diagnostic Online Mode. The Diagnostic Online Mode of CAT allows<br />
visualizing, analyzing and logging of certain traffic on the bus (a diagnostic service and the<br />
corresponding response).<br />
For Analyzing and Visualization the Diagnostic Online Mode offers to open the:<br />
Diagnostic Online View<br />
Displaying the diagnostic service request and even multi frame respond.<br />
Being Diagnostic Online the received and transmitted data are logged to the buffer on CAT Hardware.<br />
The Buffer content is first stored only on the Hardware. Only after uploading the buffer there is access<br />
to this data in the Offline respectively Diagnostic Offline Mode.<br />
! If the user disconnects the Hardware from the Power Supply (by disconnecting the CAN<br />
adapter cable) and has not uploaded the buffer the user will loose the logged data!<br />
175
Diagnostic Online Filtering<br />
The Diagnostic Online mode still supports the filtering features of CAT even if filtering in Diagnostic<br />
Online mode is usually not needed.<br />
CAT allows defining 10 different "Pass Through" Filter based on Frame Identifier and Data that are<br />
received. The filter have to be defined and selected in Offline mode. (See Filter List and Filter<br />
Definition for more details.)<br />
The selected filter can be activated and deactivated in any mode: Online, Diagnostic Online, Offline or<br />
Diagnostic Offline.<br />
To activate selected Filter<br />
Choose menu item Commands | Filter or use hot key combination CTRL + F to start the Filtering. It is<br />
independent in which mode CAT has been before.<br />
To deactivate selected Filter<br />
Choose menu item Commands | Filter or use hot key combination CTRL + F to stop the Filtering. It is<br />
independent in which mode CAT has been before.<br />
Note: The filter has no influence on the transmission of frames by CAT including the launch of<br />
diagnostic services.<br />
176
Launch Service Diagnostic Online<br />
Choose menu item Commands | Diagnostics to open the Online Diagnostic Launch dialog as shown<br />
below. As an Online Control window there is no need to close the window to work on. Just shift it aside<br />
to have a free view on the main application and shift it back when it is needed again.<br />
This dialog allows launching a diagnostic service in accordance to the settings that have been done<br />
offline before. See Diagnostics for details about the setup of the Main Diagnostic Launch Table and so<br />
the Online Diagnostic Launch dialog.<br />
Click on the launch button to transmit the displayed service. If periodic transmission of the service is<br />
adjusted the Launch button turns into a Stop button.<br />
Press the Stop button to stop the transmission. The Stop button turns back into a Launch button.<br />
Note: All diagnostic services are sent out as USDT (Unacknowledged Segmented Data Transfer)<br />
requests.<br />
Note: The filter has no influence on the transmission of frames by CAT including the launch of<br />
diagnostic services.<br />
Note: When going diagnostic online the Online Diagnostic Launch window is opened automatically.<br />
According to GMLAN the following services require a tester present service. For these services the box<br />
under "Tester Present" on the left side of the dialog should be marked if not otherwise required for<br />
testing purposes.<br />
- ($AA) Read Data by Packet Identifier,<br />
- ($AE) Device Control.<br />
- ($27) Security Access,<br />
- ($10) Initiate Diagnostic Operation,<br />
- ($28) Disable Normal Communication,<br />
CAT sends out the tester present service automatically just before the wished service and then every 2<br />
seconds (may vary, depending on the bus traffic) when Tester Present box has been marked before in<br />
Offline or Diagnostic Offline mode.<br />
The tester present service is sent until either the Service Return to Normal Mode is sent or when<br />
changing into Offline respectively Diagnostic Offline Mode.<br />
177
Offline Analyzing<br />
178
Offline Analyzer Mode<br />
Choose menu item Commands | Offline to go Offline. See Changing CAT Modes for details and how to<br />
leave the Offline Mode. While in Offline Mode the user can analyze logged data or do several settings.<br />
The Frame or the Trace List View , the Signal List and the Status Bar can be used to visualize the bus<br />
traffic. Choose menu item Windows | to open/ close the windows.<br />
Note: After being Online the Buffer has to be uploaded before accessing the logged data. Otherwise<br />
the buffer data that have been uploaded before will still be shown. This could be helpful if a short<br />
review of the last test is wished before opening the new results. See Buffer Handling for details.<br />
For Analyzing the Offline Mode offers to open the:<br />
Frame List View<br />
The Frame List displays up to 10 frames but only the frames that are selected to be displayed (see<br />
Frame List Configuration).<br />
In Offline mode the data according to the logged data of the actual buffer entry will be displayed.<br />
The Name, ID and Format will be displayed if the frame is selected to be displayed.<br />
Trace List View<br />
Different from the Frame List the Trace List View displays all frames that are acquired. The data<br />
according to the logged data will be displayed. The actual buffer entry is shown on the top of the<br />
Trace List View.<br />
Note: Trace List View and Frame List View exclude each other;<br />
opening one closes automatically the other.<br />
Signal List View<br />
The Signal List displays up to 20 signals but only the signals that are selected to be displayed (see<br />
Signal List Configuration).<br />
In Offline mode the data, according to the logged data, of the actual buffer entry will be displayed.<br />
The color of the characters for the signal value changes from black to red and vice versa each time<br />
the same signal has been received again.<br />
Status Bar<br />
The Status Bar displays the most significant data about the CAN bus traffic. In Offline Mode the<br />
data, according to the logged data, of the actual buffer entry will be displayed.<br />
(See also Buffer Handling and Find It )<br />
! If the user disconnects the Hardware from the Power Supply (by disconnecting the CAN<br />
adapter cable) and has not uploaded the buffer the user will loose the logged data!<br />
179
Error Interpretation<br />
The status bar of CAT provides in any mode but the Diagnostic Online mode information about the<br />
CAN bus status:<br />
Bus Status:<br />
The Bus Status as provided by the status flag of the CAN chip is displayed.<br />
Rx Errors:<br />
Different to the bus status not the Rx counter as provided by CAN chip is displayed but the real number<br />
of Rx Errors that have occurred on the bus since going online are displayed. Independent of the Error<br />
Type the counter is increased each time by one.<br />
Tx Errors:<br />
Different to the bus status not the Tx counter as provided by the CAN chip is displayed but the real<br />
number of Tx Errors that have occurred on the bus since going online are displayed. Independent of the<br />
Error Type the counter is increased each time by one.<br />
In Offline Mode the Trace List View as shown below provides additionally an interpretation of the<br />
Error Code Capture register of the SJA1000 CAN controller used by CAT.<br />
Accu:<br />
The accumulated numbers of Rx and Tx errors occurred on the bus are displayed. (The same value that<br />
is provided by the status bar.)<br />
Chip:<br />
The Rx and Tx error counter values are displayed, as provided by the CAN chip.<br />
Note: The error counters are modified according to certain rules. So the step size of increasing a<br />
counter allows already an interpretation. Generally the counter increases by 8 if the node probably is<br />
responsible for the error itself. Otherwise it is increased by 1.<br />
180
ECC:<br />
CAT reads out The Error Code Capture (ECC) register of the SJA1000 CAN controller. The<br />
hexadecimal value (here D9) is displayed and interpreted. The meaning is displayed as real text.<br />
The first text part (here Tx) is the interpretation of the ECC.5 Bit, indicating if the error occurred during<br />
reception or transmission.<br />
The second text part (here Other) is the interpretation of the ECC.6 Bit & ECC.7 Bit, indicating the<br />
error type. Possible types are Bit, Form, Stuff and Other Errors. Other stands for CRC or<br />
Acknowledgement Errors.<br />
The third text part (here Acknowledge Slot) is the interpretation of the ECC.0 Bit to ECC.4 Bit,<br />
indicating the error event.<br />
181
Buffer Handling<br />
CAT uses the serial COM ports to communicate with the PC. So it is not possible to transfer and store<br />
the bus traffic directly in real time on the PC. Not to miss any CAN message CAT Hardware provides<br />
enough buffer space to store about 50,000 CAN frames.<br />
The buffer is build up as a circular buffer. When logging more than 50,000 frames the first entries will<br />
be overwritten (No. of Overflows is displayed in Status Bar). Use the filter possibilities or stop logging<br />
by time to assure not to loose data by overwriting them.<br />
The total 50.000 frame buffer on CAT Hardware contains two parts:<br />
- - the Logging Buffer,<br />
The logging buffer contains all CAN data that are received from the bus (unless there is no filter) and the<br />
data that are transmitted by CAT.<br />
- - the Diagnostic Buffer.<br />
The diagnostic buffer contains the diagnostic data that are received from the bus (unless there is no filter)<br />
and the data that are transmitted by CAT.<br />
The user can configure how much of the total 50.000 frame space is used for the Logging and how<br />
much for the Diagnostic Buffer. See Buffer Setup for details.<br />
Being Online the Buffer content is first stored only on the Hardware. Only after uploading the buffer<br />
there is access to this data in the Offline respectively Diagnostic Offline mode.<br />
! If the user disconnects the Hardware from the Power Supply (by disconnecting the CAN<br />
adapter cable) and has not uploaded the buffer the user will loose the logged data!<br />
Analyzing Buffer content<br />
After being Online the Buffer has to be uploaded before there is access to the logged data. Otherwise<br />
the buffer data are still displayed that has been uploaded before. This could be helpful if a short review<br />
of the last test is wished before opening the new results.<br />
Being Offline, after uploading the buffer it is possible to Export Logging Buffer, respectively to Export<br />
Diagnostic Buffer to save the results of a test. The created files are readable by Excel so the buffer<br />
content can be analyzed using the typical Excel features.<br />
Otherwise the user can scroll through the buffer using in CAT Offline respectively Diagnostic Offline<br />
Mode the:<br />
- Trace List View<br />
In the Trace List View every buffer entry is visible.<br />
- Diagnostic Output<br />
In the Diagnostic Output every diagnostic related buffer entry is visible.<br />
- Frame List View<br />
In the Frame List View only the buffer entries are visible that are defined to be displayed.<br />
182<br />
Note: There is no visible scrolling by changing the position of the entries only the data<br />
change. Have a look to the Status Bar where the time is changing.<br />
- Signal List View<br />
In the Signal List View only the buffer entries are visible that are defined to be displayed. Each time<br />
the same signal has been received again the color of the value character switches from black to red<br />
and vice versa.
Note: There is no visible scrolling by changing the position of the entries only the data and<br />
color change. Have a look to the Status Bar where the time is changing.<br />
- Status Bar<br />
In the Status Bar every buffer entry is visible.<br />
To review the buffer content there are several auxiliary features to support the user. The user may use<br />
hot keys or the scroll bar to scroll one by one or stepwise in a defined step size. See Scrolling Step Size<br />
for details. To jump directly to certain entries use the command Find It . To reach the Trigger event<br />
simply press "T" as hot key.<br />
Do NOT wait when uploading.<br />
If the information window shown below displaying the status of the buffer upload process should be<br />
open, shift it to the side and click into the window that shall be used. Then use the hot keys for buffer<br />
scrolling to review the logged data.<br />
Although the Upload process is not finished the user can jump to the end of the buffer (using the End<br />
key). CAT will load immediately the required data. So there is no need to wait for the finish of the<br />
upload.<br />
Note: The green bar symbolizes the status of the upload of the logging buffer and the yellow bar<br />
symbolizes the status of the upload of the diagnostic buffer.<br />
183
Find It<br />
CAT provides a search command to allow the user easily to find certain frames in the buffer. Using the<br />
different possible Views in Offline respectively Diagnostic Offline, the user can open the dialog box<br />
shown below by activating Commands | Find It ...<br />
Define the search criteria as described below and press the Find Next button to start the search. Press<br />
the button again to find the next buffer entry that fulfils the done description.<br />
Note: If no next entry fits to the defined frame, you will be asked if you want to continue the search<br />
at the top / bottom of the buffer (depending on search direction).<br />
ID<br />
Input the CAN ID of the frame you are looking for. (Here $641: ID of Diagnostic Response to a request<br />
with ID $241.)<br />
Note: Let input field blank to search independent of the CAN ID.<br />
Format<br />
Input the CAN Format of the frame you are looking for. (STD for standard 11bit ID and XTD for<br />
extended 29 bit ID)<br />
Data<br />
Input the Data Bytes as hexadecimal values of the frame you are looking for. (Here 3 rd Byte = 5A:<br />
Indicating a positive respond to a diagnostic service $1A request Read Data by ID.)<br />
Note: Let any of the 8 input fields blank to search independent this field.<br />
Direction<br />
Depending on the current location in the buffer you can select if you search for the specified frame<br />
Down: checking the following frames starting with the most recently received frame after the actual<br />
positioned frame,<br />
or Up: checking the preliminary frames starting with the most recently received frame before the actual<br />
positioned one.<br />
Find Next<br />
Press this button to start searching the frame according to the defined description and setup for the<br />
search algorithm.<br />
Cancel<br />
Press Cancel to re-do the inputs that have been done and to close the window.<br />
184
Note: But you don't have to close the dialog to work on. Just shift it aside to have a free view on the<br />
main application and shift it back when you need it again.<br />

Diagnostic Offline Analyzing<br />
186
Diagnostic Offline Window<br />
In general the Diagnostic Offline Mode is identical to the Offline Mode. The only difference is that Signal List, Frame<br />
List or Trace List View are not available but the Diagnostic Output window can be opened.<br />
Choose menu item Commands | Diagnostic Offline to go Diagnostic Offline. See Changing CAT<br />
Modes for details and how to leave the Diagnostic Offline Mode. Being in Diagnostic Offline Mode it is<br />
possible to analyze logged data or to do several settings as being in Offline Mode.<br />
To visualize the diagnostic relevant bus traffic the Diagnostic Output window and the Status Bar can be<br />
used.<br />
Choose menu item Windows | Diagnostic View to open/ close the window.<br />
Note: After being Online you have to upload the Buffer before you have access to the logged data.<br />
Otherwise you will still see the buffer data that have been uploaded before. This could be helpful if a<br />
short review of the last test is wished before opening the new results. See Buffer Handling for details.<br />
For Analyzing while in the Offline Mode the user must open the:<br />
Diagnostic Output<br />
The Diagnostic Output window displays all diagnostic relevant frames and data that are acquired if CAT recognizes<br />
them as Diagnostic data. The data according to the logged data are displayed and interpreted. The data the buffer<br />
pointer faces are shown on the top of the Diagnostic Output window.<br />
Status Bar<br />
The Status Bar displays the most significant data about the CAN bus traffic. In Offline Mode the data according to the<br />
logged data of the actual buffer entry will be displayed.<br />
(See also Buffer Handling and Find It)<br />
! If the user disconnects the Hardware from the Power Supply (by disconnecting the CAN<br />
adapter cable) and has not uploaded the buffer the user will loose the logged data!<br />

FAQ Offline Setup<br />
64 bit UNM Unsigned Numeric Signals<br />
Q1: I would like to setup a 64 bit UNM Unsigned Numeric signal as defined for my system. But there<br />
are maximal 32 bit adjustable for Unsigned Numeric signals.<br />
A1: CAT does not support 64 bit UNM Unsigned Numeric signals but there is an easy workaround.<br />
Setup this particular signals as BCD (packed binary coded) signals. So you can display them with<br />
hexadecimal values. To display 64 bit UNM Unsigned Numeric signals with decimal values is not<br />
possible.<br />
Saving of sessions<br />
Q2: I tried to save the session, but I couldn't find a SAVE command, instead I used the menu item<br />
"SAVE AS..." and found after executing the "SAVE AS..." command several times multiple equally<br />
named sessions.<br />
A2: You never have to save any of your sessions. As soon as you click on OK of a dialog window, the<br />
last settings are stored immediately. The "SAVE AS..." command is used as in any other MS<br />
application, e.g. word. But: The currently opened session can be saved again under same name. You can<br />
stay with the same session name or change it. The currently open session will not overwrite the old one,<br />
even if the old and current one have the same name. (This allows to exchange sessions even with the<br />
same name.) See Session Management in the Online Help for details.<br />

FAQ Online Mode<br />
Bus Status : Error Active<br />
Q1: Going Online, the status bar displays the bus status (BusSts):Error active . Did a bus error<br />
occur?<br />
A1: This is a CAN protocol specific term. The displayed Bus Status is provided by the status flag of<br />
the CAN chip. Error active is the normal status of the CAN bus communication. It indicates that the<br />
"CAT" is taking part in the communication of the bus and is allowed to send active error flags<br />
(dominant). If the bus status would be "Error passive", it would indicate that the "CAT" is still<br />
taking part on the communication but is only allowed to send passive error flags (recessive).<br />
