Required driver version
Driver (CANLIB) version 4.1 or later is required to use the Kvaser Memorator Light.
5.7
CAN bus termination
Every CAN bus must be terminated with a 120
Ω
resistor at each end of the bus.
The Kvaser Memorator Light does not contain any CAN bus terminators, 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

acknowledgement bits on the bus. Therefore, two other nodes must exist on the
