The interface box can be used to add, or extract, normal standard audio
and/or video signals to, or from, your Colour Observation system.
This means that the interface box can be used to connect a third party
camera to your Colour Observation system. It can also be used to
connect e.g. a Cash Register Interface to the Colour Observation system,
or to connect a system camera to a third party system.
Other possible configurations are described in chapter 'Possible
configurations'.
Selection between the twisted pair system cable input and CVBS/Audio
input is done by means of an outside switch.
Installation
Remark: When the system configuration is altered, the system monitor needs to check
and memorise the configuration of the cameras and accessories connected to its inputs.
This is done automatically when the power is switched on. Use the power switch to
switch off; only operating the power save key is not sufficient. If switching off is
impracticable, use the auto install option of the system monitor's install menu.

System cable
For the interconnections between the monitor, accessories and camera,
a system cable is supplied. For an optimum picture and sound quality,
you should always use 4-wire dual twisted-pair cable when extending the
connection (max. 300m/900ft). The cable and plugs are available in the
hobby and professional trade. Fix the connectors to the cable
corresponding to the figure below.
Caution: The plugs used for the observation system have the same dimensions as
standard telephone plugs.
Never connect the security system with telephone equipment!
External power supply
If the cable length between monitor and system camera exceeds
200m/600ft after an accessory is inserted in the line, a mains power
adapter (optional) should be used to power the system camera
(see accessories). In this way the max. allowed cable length is extended to
300m/900ft.

There are two ways to connect a mains power adaptor to the system;
•To the external supply socket at the rear of the system camera, or
•to the external supply socket (4) at the inside of the interface box.
Remark: This does not apply for the VSS2903/19T.

Settings
Input selection switch (10)
With this switch you can select which audio/video input is displayed on
the screen of the system monitor.
There are two possibilities:
•CAMERA
The system camera input is selected.
When a system camera is connected, the system monitor reproduces the
image and sound from the system camera.
•AUX.
The auxiliary input is selected.
When a third party camera is connected, the system monitor reproduces
the image and sound of the third party camera.
Remark: It is not possible to connect both a device to the aux. input and to the
camera input when the selector switch is in camera position.
Internal switches
Remark: This option does not apply for the VSS2903/19T.
Two switches, located on the circuit board inside the case, are used to
configure the circuit according to the system. The two small slide
switches have the following functions:
Switch Description
24V INT EXT Power supply (24V) Internal/External
LAST YES NO Last in line
9
g
Power supply Internal/External (6)
Set this switch to;
•INT
When no external power supply is used.
•EXT
When an external power supply is used.
Last in line switch (6)
Set this switch to;
•YES
When the interface box is the last accessory box in the system cable.
•NO
When another accessory box is connected to the system camera input of
the interface box.
Volume preset (7)
By means of the volume preset, you can adjust the audio level of the
device (for e.g. of a third party camera) which is connected to the 'audio
in'-input.
Cable length compensation selector (5)
This selector adapts the interface box to the length of the system cable
connecting system monitor and interface box. This to optimize the
picture quality. Set the cable length compensation selector to the correct
cable length. The length set must be the same as the length of the system
cable connecting the system monitor and interface box
(0-300m/900ft max.).
Remark: This only compensates for the aux. input.

Possible configurations
This section shows the system configurations which are possible with the
interface box. The figure below shows a block diagram with the
audio/video signal paths.
The following configurations are possible:
Remark: In some configurations, the camera cannot be synchronised to the system
monitor (not locked). When a quad monitor is used in quad mode, it will result in
unusable pictures.
