2.2.1. Termination switch [3a] and indicator [3b]

In general, the CAN-Bus has to be terminated on both ends of a CAN-

Bus segment. Please refer to the technical information TI 312

d&b Remote network for more detailed information.

The R70 interface has a built-in switchable terminator which can be

activated when only one of its CAN connectors is used (refer to the

wiring examples given in the following section).

To terminate the interface:

• Set the termination switch [3a] to TERMINATE. The corresponding

status LED [3b] lights up.

In this case both RJ 45 connectors are terminated as shown in the

graphic opposite.

The two RJ 45 M terminators supplied with the R70 interface

Note:

must not be used to terminate the interface if the termination switch is

set to TERMINATE. They are used to terminate the last device of a

CAN-Bus segment (refer to the following section).
