4.1 Placing the transmitter and receiver

Practical experience has shown that an optimum recep-
tion is achieved when placing the units at a height of min-
imum 1.5 m to 2 m above the ground. Prior to the final
placing, a trial run is recommended as the transmission
quality can substantially be changed by displacing the
transmitter and the receiver by a few centimetres only.
4.2 Connections
1) Connect the transmitter with its BNC plug (1) to the
video output of the camera.
2) The transmitter is operated with a DC voltage of
12 V. If the camera also operates with 12 V, the
transmitter and the camera can be operated
together via a 12 V power supply unit:
a) Connect a regulated 12 V power supply unit to
one of the two jacks (6) of the transmitter. The
current consumption of the transmitter is 50 mA.
A plug 5.5/2.1 mm (outside/inside diameter) is
required. The centre contact must be at the posi-
tive pole.
b) Connect the short connection cable (3) to the
second low voltage jack (6) and to the 12 V
power supply jack of the camera. The connec-
tion cable
5.5/2.1 mm. If required, use another, matching
plug for the camera connection.

is equipped with two
If the camera should not operate with 12 V, the
transmitter and the camera must be supplied sepa-
rately.
3) Connect the jack A/V (9) to the monitor via the
adapter cable provided:
connect the red phono plug to the audio input,
connect the yellow phono plug to the video input
4) Connect the supplied reception antenna (11) to the
SMA jack (12). Alternatively, with insufficient receiv-
ing quality, it is also possible to use a 2.4 GHz direc-
tional antenna with corresponding gain, e. g. an
antenna of the DX series from MONACOR.
5) Connect the plug of the supplied 8 V power supply
unit (10) to the jack DC8V (7) and the power supply
unit to a mains socket (230 V~/50 Hz).

4.3 Channel selection

The wireless transmission is made in the 2.4 GHz
range which has been divided into four channels for the
series of units AV-4xxSET. Two transmission systems
can be operated at the same time, e. g. to transmit the
pictures of two cameras. For this purpose always one
channel between the two transmission channels must
remain free, so that they do not interfere with each
other. The following channel combinations are possible:
channel 1 and channel 3 or
plugs
channel 1 and channel 4 or
channel 2 and channel 4
