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 AVU6004A
and AVU6008A transmitters can be
cascaded. However, it is not possible
to cascade the serial port of the
AVU6001A, 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).
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).
3 If serial connections are required, attach a serial
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).
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.
