1 IntroductionAs a powerful tool the CAN converter supports development, service, testing and maintenance ofCAN-based systems. They are suitable for online monitoring and manipulation of the bus as well astheir logging.The converter supports 11 and 29 bit identifiers (CAN2.0A/2.0B). The Listen Only mode it is notransmission of Ack bit and error frames, thereby influencing the CAN system is avoided.The CAN baud rate is detected automatically by the converter. As well the converter provides theability to adjustthe baud rate and other parameters to your needs.The CAN Converter is ideally suitable for the investigation of the CAN bus data. The converter can beeasily plugged into any RS232 or RS485 port of a computer or notebook. The data can be displayedin any standard terminal program or the 4N-CAN-terminal program.More information can be found in the following sections.

2 StartupBefore first use:• Connect converter on RS232/RS485 side with your pc RS232/RS485-port• Connect CAN-side with your application• Start the terminal programIn our download area you will find the converter optimized for the terminal program: 4N-GXCAN-Terminal• Choose the right COM port• Set COM port to 38600 Baud 8N1• Power on the converter• Send within 5 seconds a "s" (initiates the setup mode)• The converter responds "CAN2.0 – RS232/RS485 Converter V4.4"• Send "h" for help output in the terminal• Set CAN side configuration as needed• Send "E" - Stores settings in the flash and restarts the converter. ( - corresponds to"Enter" key)• DoneImportant:Sending a "s" within 5 seconds switches the converter into setup mode. Options of this mode will bedescribed later. "E" or "Q" ends the setup mode.E - Saves Configuration to the converters flash memory, and exits the setup modQ - Exit without savingFor the operation of the converter, the following setup parameters must be set correctly:• CAN Baudrate (or Autobaud)• ID (results in 11- or 29-Bit Format)• Acceptance-Code• Acceptance-Mask• RS232/RS485 Baudrate

4.1 CAN ID Filter SetupThe converters accept messages from specific IDs which can be defined by the CAN identifier (CI), theCAN-Acceptance-Code (CAC) and the CAN-Acceptance-Mask (CAM). CAC defines the mandatoryrequired bits of the received ID and the CAM, the bits to ignore. The CAN identifiercan be determined by the choice of converter id to whether either will be accepted ONLY 11bits (id

4.2 CAN ModesThe converter is in Listen Only mode or normal mode to operate.L = 1 Listen Only Mode (read without ACK) L = 0 Normal Mode (read and write)5 Normal ModeIf the converter powered on and the setup mode is not initiated within 5 seconds, it starts innormal mode. In this mode, the communication of the CAN bus can be monitored (chapter:5.2 Receive Data) and data be transmitted to the bus (chapter: 5.1 Sending Data).5.1 Sending DataAll Data, sent from the computer to the COM port, will be output on the CAN bus.The following formats are used:ID CR space = $20 (Space "_") CR = $ 0D (Enter "") - ID without DataID space Data CR space = $20 (Space "_") CR = $ 0D (Enter "") - ID with DataWith the converter setting:CAN-Identifier = 1F000000 (29 Bit CAN-Identifier)the following data is output: (11 and 29 bit messages)InputMeaning7E8_0001020304 CAN ID 7E8 Data 00 01 02 03 04 Data Length 57E8_0 CAN ID 7E8 no Data Data Length 07E8_01_01 CAN ID 7E8 Data 01 Data Length 11FFFFFFF_010203_03 CAN ID 1FFFFFFF Data 0102030 Data Length 310001234_0102_02 CAN ID 10001234 Data 01020 Data Length 2With the setting:CAN-Identifier = 1FF (11 Bit CAN-Identifier)the following data is output: (only 11 bit CAN messages)InputMeaning7E8_0001020304_05 CAN ID 7E8 Data 00 01 02 03 04 Data Length 57E8_0 CAN ID 7E8 no Data Data Length 07E8_01_01 CAN ID 7E8 Data 01 Data Length 1In case of 11 bit ID no 29 bit ID messages will be sent!5.1.1 Send ErrorIf data is sent in the wrong format to the converter through the USB/COM port, it can be recognizedby the converter response "S" (Enter "S" Enter).e.g.: 1FFFFFFF_010Converter response: "S"(incomplete data, 0101 would be correct)

5.2 Receiving DataWhat data received by the converter and at RS232/RS485 side are output for further processingdepends on the configuration of the CAN identifier, the CAM-Acceptance-Code and the CAN-Acceptance-Mask. A detailed description of these parameters can be found with examples inchapter "3.1 CAN ID Filter Setup".Accepted CAN messages will be output in ASCII format as followed:ID space Data space Length CRspace = $20 (Space "_") CR = $ 0D (Enter "")With the converter setting:CAN-Identifier = 1F000000 (29 Bit CAN-Identifier)CAN-Acceptance-Code = 00000000 (0 receives all CAN-Frames)CAN-Acceptance-Mask = FFFFFFFF (F receives all CAN-Frames)the following data is output on the USB side: (11 and 29 bit message)PC OutputMeaning7E8_0001020304_05 CAN ID 7E8 Data 00 01 02 03 04 Data Length 57E8_0 CAN ID 7E8 no Data Data Length 07E8_01_01 CAN ID 7E8 Data 01 Data Length 11FFFFFFF_010203_03 CAN ID 1FFFFFFF Data 0102030 Data Length 310001234_0102_02 CAN ID 10001234 Data 01020 Data Length 2With the setting:CAN-Identifier = 1FF (11 Bit CAN-Identifier)CAN-Acceptance-Code = 00000000 (0 receives all CAN-Frames)CAN-Acceptance-Mask = FFFFFFFF (F receives all CAN-Frames)the following data is output: (only 11 bit CAN messages)PC OutputMeaning7E8_0001020304_05 CAN ID 7E8 Data 00 01 02 03 04 Data Length 57E8_0 CAN ID 7E8 no Data Data Length 07E8_01_01 CAN ID 7E8 Data 01 Data Length 15.2.1 Receive ErrorError LED (Buffer Overflow LED) lights up, if data is sent to fast from the PC to the converter.Buffer Overflow can be recognized by "E" (Enter "E" Enter)."E" is send from converter to PC.At full CAN bus utilization can rarely cause errors (at 1 Mbps 100% bus utilization).To recognize this is the fact that the messages are not received in full.z.B.7E8_000102 CAN ID 7E8 Data 00 01 02 ?
