PCAN-Diag 2 – Measuring Functions for the CAN Bus

Menu item

Measurements

CAN Termination

Note:

This function is only available if the PCAN-Diag is

equipped with a High-speed CAN transceiver (display at

Device Settings

Transceiver: High speed

The function measures the resistance value between the CAN_L and
CAN_H lines. While doing so the CAN traffic is not affected.

A High-speed CAN bus (ISO 11898-2) must be terminated with
120

on both ends between the CAN lines CAN_L and CAN_H. This

measure will prevent signal reflections at the cable ends and a
correct function of CAN transceivers attached to the CAN bus is
assured.

The two termination resistors in parallel result in a total resistance
of 60

. The measurement of the total resistance provides informa-

tion about a correct CAN bus termination.
