Cabling - Peak PCAN-USB FD User Manual

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 PCAN-USB FD has an optional internal termination with 120 Ω. For more
information see chapter 2.2 Internal Termination.
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.
