Cascading Transmitters - ADDER AdderLink AV series User Manual

Cascading transmitters

Expansion at the transmitter end
is achieved using the video and
audio output ports. The signals
from these ports are connected
to the video and audio inputs of
the next transmitter and so on.
AdderLink AV100 and AV104
transmitters can be mixed in a
cascade in any order using the
method discussed here.
The RS232 serial port of an AdderLink AV200
transmitter cannot be cascaded, therefore, if
an AV200 transmitter is involved in a cascade,
it should be placed as the primary transmitter,
connected directly to the source PC system.
NOTE: Ensure that there are no more than three cascades
(transmitter or receiver cascades) between the primary
transmitter and the furthest receiver in any branch.
To connect cascaded transmitters
1 Attach a video cable of suitable type and length (fully shielded with
15 way male D-type connectors at both ends, 2m or less - Adder part
number: VSC18) to the socket labelled
transmitter.
2 Attach the other end of the video cable to the socket
IN
labelled on the secondary AdderLink AV transmitter.
3 Attach a stereo audio cable (shielded with three
way 3.5mm jack plugs at both ends - Adder part
number: VSC22) to the socket labelled
the primary AdderLink AV transmitter.
4 Attach the other end of the stereo audio
IN
cable to the socket labelled
secondary AdderLink AV transmitter.
5 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.
