■ Installations
The installations described below should be made by
qualified service personnel or system installers.
● Modifying the Front Panel
Peel the tape off the supplied panel templates, then attach
them on the front panel of the system controller.
● Connection with the WV-CU550C System
Controller
If the supplied 6-conductor cable assembly is used, simply
plug one end of the cable into the DATA IN port of the
video multiplexer and the other end into the DATA OUT port
on the system controller.
If you use cables assembled from locally procured materi-
als, it is important that only high quality, data grade cable,
suitable for RS-485 communication (shielded 4-wire twisted
pair cable) is used.
Low grade cable will result in unstable operation of the sys-
tem.
