Termination of the CAN Busses

If the PCAN-Router FD is connected to one end of a CAN bus and if
there's no termination of the CAN bus yet, an internal termination
with 120



between the lines CAN_H and CAN_L can be activated.

Termination is possible independently for both CAN channels.

Position of the solder fields for the termination of the CAN bus

(CAN1 on the left, CAN2 on the right)

Without termination

(Default)

With termination
