Operation; Specifications - Monacor AV-3000TX Bedienungsanleitung

50 m by walls and ceilings, depending on their condi-
tion. By using an antenna with gain at the receiver,
however, the range can be increased many times over.
3.1 Approval
According to the R+T TE directive (Radio and Tele-
communication Technical Equipment), the approval
for the transmitter is valid in the countries of the Euro-
pean Union. For operation in countries outside the EU,
please contact your retailer or the MONACOR subsi-
diary in the country where this unit will be operated.

4 Operation

4.1 Placing the transmitter and the receiver
Practical experience has shown that an optimum
reception is achieved when placing the units at a
height of minimum 1.5 m to 2 m above the ground.
Prior to final mounting, a trial run is recommended as
the transmission quality can be substantially changed
by displacing the transmitter and the receiver by a few
centimetres only.
4.2 Mounting
1
A 6.3 mm ( / ") thread jack is supplied with the trans-
4
mitter for mounting it on a support or a stand. This
thread jack can be attached to the transmitter housing
by means of commercial plastic adhesive.
4.3 Channel selection
The wireless transmission is made in the 2.4 GHz
range which has been divided by the manufacturer
into five channels with a distance of 14 MHz. As a
maximum, three channels can be used simulta-
neously (channels 1, 3, and 5) as two adjacent chan-
nels will interfere with each other. The following chan-
nel selection is recommended:
for two cameras: channels 1 and 5
for three cameras: channels 1, 3, and 5
Adjust the desired transmission channel with the DIP
switches on the rear side of the housing. The required
position of the switches can be found in fig. 2 and on
the lower side of the transmitter. Adjust the receiver to
the same channel.
4.4 Connections
1) Feed the video signal of the camera or the signal
source via a 75 Ω coaxial cable to the phono jack
"video" (2). The level of the video signal must be
1 Vpp according to standard.
2) For audio transmission, feed the audio signal of
the camera or the signal source via a shielded
audio cable to the jack "audio A" and, in case of
stereo transmission, additionally to the jack "audio
B" (3). The input sensitivity is 500 mV.
3) If the receiver used is provided with a control
channel, it is possible to activate an optical or
acoustic signal device or another additional unit
connected to the receiver via this channel (e. g.
video recorder for automatic start of a recording).
On the transmitter, the control channel is activated
by short-circuiting the input "switch" (4). Connect
e. g. a motion detector with NO (normally open)
contact to these terminals.
4) For power supply, a regulated power supply unit
with a minimum output current of 150 mA is re-
quired, e. g. MONACOR PS-362ST. In case of
power supply units with variable output voltage,
adjust a value of 12 V (±0.5 V). Connect the power
supply unit via a low voltage jack 5.5/2.1 mm (out-
side/inside diameter) to the plug "12 V
Always observe the correct polarity: connect the
positive pole to the inner contact of the plug. After
the supply voltage has been applied, the transmit-
ter is ready for operation.
