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:
