Communication problem

Post by vanderlei » Wed 12. Aug 2015, 06:42

Hi,

Sorry about my English.

My PCAN stopped communicating with the equipment, but PCAN is detected by the microcomputer.
With PCAN-View bite rate above 100 bit/s is shown an error "busoff" or "BUSHEAVY".
What could be happening?

Best Regards

Hi,

please check your CAN cables for correct termination resistors on both ends (120Ohms betwen CAN-L and CAN-H). When you use different baudrates, please check that your other connected CAN devices uses the same baudrate.

You can also test your PCAN-USB hardware (transceiver check) with a voltmeter:
