Hardware Installation
This chapter describes the installation of the system
hardware. For details of operation, see the supplied
Operation Instructions.
Note
Ensure that you read all safety precautions.
2.1 SYSTEM CABLE
For the interconnection between the monitor and cam-
era a 15m/45ft system cable is supplied with the camera.
For an optimum picture and sound quality you should
always use 4-wire dual twisted-pair cable when extend-
ing the connection. The maximum allowed cable length
is 200m/600ft. Pay attention that the connectors are
fixed to the cable corresponding to the figure below.
(Figure 2.1) If the length of the system cable is over
200m/600ft (up to 300m/900ft), an interface box should
be used to feed the accessory or camera (see optional
accessories in the Operation Instructions).
2.2 SYSTEM CONNECTION
2.2.1 Camera inputs (1 to 8)
The cameras are connected to inputs 1 through to 8,
depending on the number of cameras used. The input is
related to the image position (by 3x3 and Quad) on the
screen.
2.2.2 Slave output
An output for a slave monitor (optional accessory) is
available.
2.2.3 Aux. output/input
You can configure an auxiliary output configuration via
the menu option (see System settings). The auxiliary
output provides loop-through from one of the 8 camera
inputs or presentation mode where you can connect
another video source to aux-in. It is possible to switch
between this video source and one of the camera pic-
tures.
Note
The supplied A/V cable can be used for Aux. output/
input connection. However, if you are using two Video
Recorders you will need to order a second A/V cable
(see your local supplier).
•
Connect the Mini Din plug to the Aux. connector of
the system monitor.
Caution
The plugs used for the observation system have
the same dimensions as standard telephone
plugs. (RJ-11) Never connect telephone equip-
ment or cable to the observation system.
