PCAN-RS-232 open CAN port hangs the CAN bus

Post by chuinfong » Mon 16. Nov 2015, 03:21

Currently I am trying to use PCAN-RS-232 to tap into NMEA2000 CAN bus. The PCAN-RS-232 I am using is running using the default firmware came with the device. By using the Terminal commands, I am able to retrieve the CAN messages from the RS-232 port. However, occasionally (especially when I sent the command slowly, i.e. long interval between terminal commands), I receive no data from the RS232. Further probing on the CAN bus shows no activities (I have a NMEA device that constantly sending NMEA packet every 100ms). I noticed when I send command O<CR> to PCAN-RS232, the CAN bus activities suddenly just stopped (I probe the CAN bus using oscilloscope).

Here are the commands I used:

Re: PCAN-RS-232 open CAN port hangs the CAN bus

Post by G.Lang » Mon 16. Nov 2015, 10:43

Hello,

additional infos required.

-> What´s the CAN baudrate of your NMEA CAN system?
-> Is your CAN network terminated? What´s the termiantion value?
-> Which baudrate for the serial port do you use?
-> Is the LED from the module blinking 3 times after power up?
-> What´s about the power supply? Which voltage do you use?

best regards
Gunther
