Termination of the CAN Buses

Depending on the used CAN transceiver module you can activate or
change the CAN bus termination for each CAN connection CAN 1 to
CAN 4 with switch blocks S1 to S4. Switches 1 and 2 on a switch
block always must have the same position. By default, internal
termination is not activated.
Tip: We recommend adding termination at the CAN cabling, for
example with termination adapters (e.g. PCAN-Term). Thus,
CAN nodes can be flexibly connected to the bus.
Do the following to activate the termination:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the circuit board of the PCAN-Router Pro. Take

cover.

Pull out with the front panel the board from the bottom side
of the housing to the front.

Make sure that both DIP switches (1/2) on the switch block
are in the same position.
