Cabling

3.3.1

Termination

A High-speed CAN bus (ISO 11898-2) must be terminated with 120
ohms at both ends. The termination prevents interfering signal
reflections and ensures the proper operation of the transceivers of
the connected CAN nodes (CAN interfaces, control devices).
The PCAN-PC/104-Plus card does not have an internal termination.
Use the card on a terminated CAN bus.
