INSTALLATION INSTRUCTIONS
For the video signal use a TV 75
Ω
low loss coaxial cable.
Serial connection of the coaxial cable (in-
put and output from monitor)
To carry out the video connection in a serial
mode it is necessary to cut the resistance of
75
Ω

located on the wall-bracket terminal board.
Leave it only on the last monitor. The monitors
serially connectable are max. 20.
Connection of the coaxial cable with video distributors
For multi-way video systems it is advisable to
use video distributor that, being powered by the
monitors connected to it (terminal 8), do not
create overloads on the video power supply. The
outputs that are not used must be closed with
resistances of 75
Ω
that are provided in kit.
Maximum 12 video distributors can be con-
nected together.

Monitors terminal board
The resistance for terminate the video signal
(75
Ω
) is located on the terminal board of the
monitor wall bracket.
VIDEO SIGNAL DISTRIBUTION WITH COAXIAL CABLE
They allow the distribution of the video signal
on 2 or 4 outputs. It can be installed on the wall,
on a wall box, with expansion plugs or it can be
placed in the junction box.
