Info

4.1 CAN ID Filter Setup The converters accept messages from specific IDs which can be defined by the CAN identifier (CI), the CAN-Acceptance-Code (CAC) and the CAN-Acceptance-Mask (CAM). CAC defines the mandatory required bits of the received ID and the CAM, the bits to ignore. The CAN identifier can be determined by the choice of converter id to whether either will be accepted ONLY 11 bits (id
4.2 CAN Modes The 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 Mode If the converter powered on and the setup mode is not initiated within 5 seconds, it starts in normal 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 Data All 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 Data ID space Data CR space = $20 (Space "_") CR = $ 0D (Enter "") - ID with Data With the converter setting: CAN-Identifier = 1F000000 (29 Bit CAN-Identifier) the following data is output: (11 and 29 bit messages) Input Meaning 7E8_0001020304 CAN ID 7E8 Data 00 01 02 03 04 Data Length 5 7E8_0 CAN ID 7E8 no Data Data Length 0 7E8_01_01 CAN ID 7E8 Data 01 Data Length 1 1FFFFFFF_010203_03 CAN ID 1FFFFFFF Data 0102030 Data Length 3 10001234_0102_02 CAN ID 10001234 Data 01020 Data Length 2 With the setting: CAN-Identifier = 1FF (11 Bit CAN-Identifier) the following data is output: (only 11 bit CAN messages) Input Meaning 7E8_0001020304_05 CAN ID 7E8 Data 00 01 02 03 04 Data Length 5 7E8_0 CAN ID 7E8 no Data Data Length 0 7E8_01_01 CAN ID 7E8 Data 01 Data Length 1 In case of 11 bit ID no 29 bit ID messages will be sent! 5.1.1 Send Error If data is sent in the wrong format to the converter through the USB/COM port, it can be recognized by the converter response "S" (Enter "S" Enter). e.g.: 1FFFFFFF_010 Converter response: "S" (incomplete data, 0101 would be correct)
