3.3 Connection of Extended Monitors
Indoor Monitor is capable of connecting multi extended Monitors.
First, connect the cable in the mount bracket, then connects the JS-VP port with the
monitor by using 4 core cable (which is Interconnection Cable in following diagram).
Extended wiring terminals are described as below:
1R
Power positive. +12V present when outdoor station calling or being
supervised.
2W
Power negative (GND)
3Y
Image signal (Video signal)
4B
Talk and control signal
It’s recommended to use RVVP 4x0.3mm
2
shielded cable. And when distance is over 50m,
we suggest to use additional coax cable RG-59 (or 3C-2V) to connect 3Y and 2W.
Note 1: JP-VD is used for setting the video impedance. When there is only one indoor
monitor, keep the jumper (which is already on JP-VD). But when multi monitors are
installed, be sure of taking away all JP-VD of monitors except only the last monitor.
