connecting an inductive load (e. g. relay), the pro-
tective diode D1 must be connected in parallel to it in
reverse direction!
4.3.3 Power supply
As a power supply a regulated power supply unit with
an output voltage between 7 V
and 30 V
is re-
quired, e. g. PS-362ST by MONACOR.
1) In case of power supply units with variable output
voltage adjust them between 7 V and 30 V.
2) Connect the power supply unit:
the positive pole to terminal 2 “DC +7 – 30V” and
the negative pole to terminal 1 “GND”.
3) Only after all other connections have been made,
connect the power supply unit to a mains socket
(230 V~/50 Hz). After applying the operating volt-
age the receiver is switched on, and the internal
power LED (7) lights up.
After the operation disconnect the power supply
unit from the mains socket.
4.4 Making the Adjustments
4.4.1 Channel selection
The wireless transmission is made in the 2.4 GHz
range divided by the manufacturer into five channels
at a distance of 14 MHz. As a maximum three chan-
nels can be used at the same time (channels 1, 3, and
5) because two channels directly next to each other
interfere with each other. The following channel se-
lection is recommended:
in case of two transmitters:
channels 1 and 5
in case of three transmitters: channels 1, 3, and 5
Adjust the receiver with the rotary switch (8) to the
channel of the transmitter:
4.4.2 Matching the video level
The video output level at terminal 8 “Video” is ad-
justed to 1 Vpp according to standard. However, if the
picture on the screen appears too bright or too dark,
match the level with the control “Videopegel” (6)
accordingly. For this purpose pierce the circle of the
label, and make the adjustment with a small screw
driver.
