Installation
1 .
Fasten the transmitter and receiver to a stable pole with the mounts.
2 . Screw the 869 MHz
[A]
antennas into SMA antenna connectors at the
top of the case .
3 . Connect the video cables with the coaxial cable
[M]
, or the UTP twisted
pair cable
[N]
.
4 . Connect the audio cables
[O]
(right channel, left channel,
signal ground) .
5 . Connect the RS-485 cables
[P]
(A+, B-).
6 . Connect the 9-14V DC power supply
[R].
Basic settings
Operating the dip-switch
SWITCH 1
[J]
– enables / disables the 120 Ω resistor (terminator) in
parallel with the RS-485 interface terminals . This resistor should always
be added at the end of every RS-485 line to avoid interference . In order
to enable the resistor (RS-485 line terminator), it should be set to the
ON position; in order to disable it, it should be set to the OFF position.
SWITCH 2
[K]
– changes the frequency band for video signal
transmission . The device can operate in two frequency ranges:
5 .733 – 5 .866 GHz (8 operating channels – ISM band, permitted within the
European Union) and 5 .705 – 5 .945 GHz
(16 operating channels – can be
used only in selected countries outside of the European Union).
In order to change the frequency band for video transmission, use switch
no. 2: OFF position – 8 operating channels, ON position – 16 operating
channels
(permitted only in selected countries outside of the EU).
Video transmission settings
Setting the video transmission operating channel
1 . In order to set the video transmission operating channel, turn the rotary
switch, labelled “VIDEO CH .”
[F]
, to the desired position .
2 . The display will show the number of the currently selected channel .
3 . After selecting the proper channel, the display will start blinking,
indicating that the settings are being saved to the device memory . Then,
the display will turn off by itself.
Data transmission settings
Setting the data transmission operating channel
1 . In order to set the data transmission operating channel, turn the rotary
switch, labelled “DATA CH .”
[G]
, to the desired position .
2 . The display will show the number of the currently selected channel .
3 . After selecting the proper channel, the display will start blinking, indicating that the
settings are being saved to the device memory. Then, the display will turn off by itself.
