CAN 2.0A/B ↔ RS232/RS485 Converter

5.2 Receiving Data
What data received by the converter and at RS232/RS485 side are output for further processing
depends 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 in
chapter "3.1 CAN ID Filter Setup".
Accepted CAN messages will be output in ASCII format as followed:
ID space Data space Length CR
space = $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 Output
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
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)
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 Output
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
5.2.1 Receive Error
Error 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.
