VIDEO SIGNAL STABILISATION
On the rear of monitor type 7211 there
are some connectors (A-B-C) for the
video signal stabilization.
This jumper must be used in installa-
tions with several appliances (interpho-
nes and monitors) connected in series
(Fig. 30).
In series configuration displace the jum-
per (only in the last set) into “B” position
and keep the jumpers of other interpho-
nes or monitors in the initial position, i.e.
“A” (Fig. 30).
For other wiring configurations see note:
"Bus termination for ELVOX TWO-WIRE
installations" provided below, in the wi-
ring diagrams section (Page. 27).
