Cascading transmitters
Expansion is achieved by linking
the video, audio and serial ports of
transmitters. The output ports of one
transmitter are connected to the inputs
of the next transmitter and so on.
The RS232 serial ports of AV204T and
AV208T transmitters can be cascaded.
However, it is not possible to cascade
the serial port of the AV200T, although
its video and audio signals can be cascaded to lower
level modules.
Note: Ensure that there are no more than three
cascade links between the primary transmitter and
the furthest receiver.

To connect cascaded transmitters
1 Attach a suitable video cable between the socket
labelled
OUT
on the primary transmitter and the
socket labelled
IN
on the secondary transmitter.
(Cable specification: Fully shielded with 15 way male
D-type connectors at both ends, 2m or less - Adder
part number: VSC18).
2 Attach a stereo audio cable between the socket
labelled
OUT
on the primary transmitter and the
socket labelled
IN
on the secondary transmitter.
(Cable specification: Shielded with three way 3.5mm
jack plugs at both ends - Adder part number: VSC22).
3 Ifserialconnectionsarerequired,attachaserial
cable between the socket labelled OUT on the
primary transmitter and the socket labelled IN
on the secondary transmitter. (Cable specification:
Shielded with 9 way D-type connectors - male at one
end, female at the other - Adder part number: CAB-
9M/9F-2M).
4 Repeat such cascade links until the required number
of transmitters (up to a maximum of four) are
present. Connect the remaining signal and power
cables to the added transmitters (and their respective
receivers) as discussed earlier within this chapter.
