2.2. Additional accessoires
The external video unit is connected using
six-wire cabling
. Use a
twisted cable
for optimal video
image quality. Also pay attention to the diameter of the wires in the cable, as this determines the
maximum distance that can be covered
between the power supply and the external video unit.
Niko recommends using the following
cables
to install the external video unit:
• JYSTY (-F2) min. 3 x 2 x 0.8 mm (max. distance 200 m)
• TVVF (-F2) min. 3 x 2 x 0.8 mm (max. distance 200 m)
• TPVF min. 3 x 2 x 0.6 mm (max. distance 100 m)
• UTP/FTP/STP 4 x 2 x 0.5 mm (max. distance 70 m)
Function of the wires to be connected:
• terminals
a and b
: communication bus (24 Vdc)
• terminals
V1 and V2
: video signal
• terminals
P and M
: extra power supply (26 Vdc)
3. INSTALLATION
3.1. Mounting and connecting the external video unit
Attention:
Disconnect all power before installing the external video unit. Do not connect the device
to the power supply voltage until installation is completed.
