CAN bus termination
Every CAN bus must be terminated with a 120 Ohm resistor at each end of the
bus. The Kvaser U100-X1 does not contain any CAN bus termination, because
their inclusion could cause severe disturbance in a system which is already
correctly terminated.
For laboratory or testing use, the exact value of the termination resistors is not
always critical. Sometimes a single terminator is sufficient. For production, proper
termination is essential. If you see error frames on the bus, you should check the
termination.
To save yourself a lot of trouble, always terminate the CAN
bus properly.

Power supply
