Making cascade connections
The Wizard AVU series of products have been specifically designed to be flexible
in order to support both your immediate and future needs for media streaming.
In addition to the standard connections made from transmitters to receivers,
you can also link extra transmitters to transmitters and/or receivers to receivers
in order to provide more display/speaker outputs. These non-standard links are
called
cascade connections
.
Important limitations when cascading
• There should never be more than three cascade connections between the
primary transmitter
(the one connected to the source PC) and any receiver.
The cascade connections can all occur at the transmitter end or all at the
receiver end (AVU5111A modules only) or at a mixture of both.
• Each cascade connection reduces the overall link length permissible from a
transmitter to the final receiver in a branch. To calculate the recommended
overall maximum link length for a branch, count the number of cascade
connections between the primary transmitter and the final receiver in that
branch. The effects of cascade connections on overall branch link lengths are
as follows:
Number of cascade connections
Overall length of links for a branch
(in a branch)
(from transmitter to furthest receiver)
0
300m (1000 feet)
1
250m (800 feet)
2
200m (650 feet)
3
175m (600 feet)
Notes
The lengths of transmitter cascade (video) connections should never be
longer than 2m (6 feet) and can be considered to have a negligible effect
upon overall link lengths.
The maximum resolutions achievable are: 1600 x 1200 x 60Hz at 650ft and
1280 x 1024 x 60Hz at 1000ft. If you are using lower resolutions then it
may be possible to achieve longer transmission distances than shown in the
above table although we do not recommend runs longer than 1000 feet
(300 metres) in any installation. If you are running shorter cables then it may
be possible to use more cascades than shown in the above table.

connections upon overall link lengths:
