Cabling

3.3.1

Termination

A High-speed CAN bus (ISO 11898-2) must be terminated on both
ends with 120 Ohms. Otherwise, there are interfering signal
reflections and the transceivers of the connected CAN nodes (CAN-
interface, control device) will not work.

The PCAN-PCI Express card does not have an internal termination.
Use the card on a terminated CAN bus.

3.3.2

Example of a Connection

Figure 6: Simple CAN connection

In this example, the PCAN-PCI Express card is connected with a
control unit by a cable that is terminated at both ends.
