Single Channel Modulator
8051VMP
The single channel modulator is configured via a series of
dipswitches, and provides channel selection from UHF 28 - 67.
Two & Four Channel Modulators
8052VMPIR / 8054VMPIR
The two and four channel Modulators are internally combined
and provide a single coaxial output. They also provide infra-red
outputs for the connection of emitters. The two channel
modulator provides two emitter connections and the four
channel version provides four.
Each of the modulator video inputs can be assigned a Channel
via the buttons on the front panel. Channel selection is from
28 - 67 in the UHF band. Four different models are available
to suit different international broadcast standards.
The two and four channel Modulators also provide power to
the Video Distribution Unit, this means the VDU does not
require power locally.
Example - To program Input A as channel 42:-
1. Press the SELECT button until the LED of input A is ON
2. Press the PROGRAM button for the tens value of the
channel to be programmed, in this case four times.
3. The LED will extinguish.
4. Pause until the LED comes back ON.
5. Press the PROGRAM button for the ones value of the
channel to be programmed, in this case two times.
6. The LEDs of the other inputs will give a rapid flash to
indicate the channel has been accepted.
To read back a programmed channel, select the channel to
read, press and hold the program button for 5 seconds then
release. The programmed channel will flash back.
If an incorrect channel selection is made, the input LED
flashes repeatedly for about a second.
If a channel is programmed that is plus or minus one or equal
to a channel already in use, the LEDs of the conflicting
channels will flash simultaneously at a slow rate.
If this happens, follow the programming procedure again,
making sure to choose an appropriate channel. It is recommended
the channels used be documented.
