CAT Diagnostic Setup
Attention: It is highly recommended not to manipulate any files of CAT software e.g. by the use of an editor.
The following is highly recommended to be done only by experienced PC users.
Professional users of the diagnostic features of CAT may need to change the diagnostic parameters
defining the handling of diagnostic frames. Therefore an editor has to be used to change the default
settings in CAT.INI file.
The file CAT.INI is located in the folder "CAT_Destination_Folder"\BIN. (CAT_Destination_Folder is
the folder that have been chosen when installing CAT)
Block Size
The PCI (Protocol Control Interface) parameter RespFlowCtrl_Bsmax (is set to 5 in sample above).
The BS (Block Size) defines the maximum number of frames which can be send before another flow
control frame has to be sent.
Separation Time
The PCI (Protocol Control Interface) parameter RespFlowCtrl_STmin (is set to 100 ms in sample
above). The ST (Separation Time) defines the minimum amount of time in ms that must be between
consecutive frame transmissions of a multi frame message.
Padding
The PCI (Protocol Control Interface) parameters PaddingSWC, PaddingMS, PaddingHS (all are set
to 0 in sample above meaning No Padding). Padding means to fill up the Data Byte Field of the CAN
Frames with 0's, so that the frames always contain 8 Data Bytes.
Set parameter PaddingSWC to 1 to have padding for the Single Wire CAN (SWC), when Single Wire
CAN has been chosen as physical layer in the CAN Setup .
Set parameter PaddingMS to 1 to have padding for the Dual Wire CAN Mid Speed (MS), when Dual
Wire CAN Mid Speed has been chosen as physical layer in the CAN Setup .
Set parameter PaddingHS to 1 to have padding for the Dual Wire CAN High Speed (HS), when Dual
Wire CAN High Speed has been chosen as physical layer in the CAN Setup .
Note: Padding -when activated- is only done for the frames send out by diagnostic services but not
for frames set up in the Transmission table.
