4.2 Cabling

4.2.1 Termination
The High-speed CAN bus (ISO 11898-2) must be terminated with 120 Ω on 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 CAN interface PCAN-PC/104 Plus does not have an internal termination. Use the
CAN interface on a terminated CAN bus.
