4.6 CAN bus termination
There are no on-board CAN bus terminators on the PCIcan II board. You must terminate the
CAN bus yourself by placing a 120 Ohms resistor between CAN_H and CAN_L at each end
of the CAN bus.
Note that without terminators on the CAN bus, the communication may or may not work
– it’s
totally unpredictable. For laboratory use the termination need not be perfect but you will
always need some load resistance between CAN_H and CAN_L somewhere on the CAN bus.
