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-PCI Express FD does not have an internal termination. Use
the CAN interface on a terminated CAN bus.
4.2.2 Example of a Connection
This example shows a connection between the PCAN Interface and a control unit
(ECU). The upper example shows a connection with a cable which is terminated with
120 Ω at both ends. At the lower example the connection is made with termination
adapters.
