I am making a CAN logger device that will be connected to the vehicle OBD port. Since the CAN bus inside the vehicle is already terminated, do I need to terminate the BUS lines on my device end, right before the line feeds to the CAN Transceiver? Please check the attached picture. The J1939+ and 1939- are the BUS lines available on the Vehicle OBD port. I have read that if the stub lines are not too long(<0.5m) , termination is not needed. The stub lines in my case is much less than 0.5m.
