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.
Note: The two RJ 45 M terminators supplied with the R70 interface
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).
