Installing and coding the backplane
The scope of delivery of every U 1xx signal converter includes a backplane to create the physical
connection between the signal converter and the base device. Both the mains HF connections
and the network connections are connected to this backplane. The temperature controlled fan for
cooling the U 1xx signal converter is located on the backplane.
2.8.1 Coding the backplane
To correctly define the position of the backplane, and thus the position of the related signal con-
verter in the U 100 base device, the jumper on the board of the backplane, which is described in
the following section, must be configured.
Figure 1: Coding the backplane using the jumper
Note:
An incorrectly configured jumper leads to incorrect displays in the front LEDs.
In addition, it is not possible to display a correct position on the Web user interface!
