2. INSTALLATION
In order to connect the TV or monitor to the video receiver, connect the coaxial cable
(75 Ω) for the video signal to terminal V (Video OUT). Connect the shield of the coaxial
cable to the mass (
⊥
). Connect the coaxial output to a coaxial input of the TV or monitor
using a 75 Ω connector. Also consult the wiring diagram below.
Attention:
Use a 75 Ω coaxial cable and 75 Ω connector in order to guarantee optimal
image quality.
Note:
Remove the jumper on the video receiver if it does not close off a row of internal
units. The jumper functions as terminal resistance.
Attention:
* In case of line cabling:
Always connect the wires for the video signal directly to terminals
V1 and V2. Branching on the wires themselves is not allowed.
* In case of star cabling: Use the splitter 10-821-01, 10-822-01 or 10-824-01 (see
product catalogue).
3. OPERATION AND USE
If the video receiver has been connected correctly, it will immediately send an image of the
Niko Access Control system to a TV or a monitor. There is no need for programming. The
camera image last activated is continuously displayed on the TV or monitor. When using a
TV, switch to the video channel (AV or EXT) to see the image. Adjust the contrast and the
brightness of the image using the two potentiometers.
