Doug Fleenor Design Marconi TX - Manual

Marconi TX Wireless DMX Transmitter
The Marconi Wireless DMX Transmitter (Marconi TX) sends all 512 channels (one
universe) of DMX512 using 2.4 GHz spread spectrum technology. DMX512 input is
on a 10" pigtail fitted with a 5-pin male XLR connector with a chassis mounted
'through' connector provided. For highest reliability, the through connector should
only be used to run a short distance to a DMX splitter or other isolation device. This
is because a cable fault on the through connector may corrupt the input signal at the
Marconi TX and hence the transmitted signal as well. If the Marconi TX is plugged
directly into the DMX source (console, splitter, computer, etc.) it is not necessary to
terminate the through connector. If a cable is placed between the Marconi TX input
pigtail and the DMX source, the through connector should be terminated.
Marconi products use the W-DMX system (invented by Wireless Solutions in
Sweden) which allows up to 16 transmitters and any number of receivers to be used
simultaneously in a single venue. Since any W-DMX receiver can listen to any
Marconi transmitter, there has to be a way to tell each receiver which transmitter to listen to. This is accomplished by
Assigning or Linking the W-DMX receiver to the Marconi transmitter. Transmitter assignment information is held in the
receiver's non-volatile memory. If the user has only one W-DMX transmitter (or keeps his systems separate), the configuration
process described below will only have to be done once for each receiver.
To assign (link, bind, etc.) a W-DMX receiver to a Marconi TX:
Both the Marconi TX and W-DMX receiver must be powered up and within range of each other.
On the W-DMX receiver, press and hold the configuration button for 5 seconds. This button may be labeled CONFIG, LINK,
ASSIGN, FUNCTION, etc. depending on the manufacturer. This will unassign the W-DMX receiver from any other
transmitter.
Using a paper clip, momentarily press and release the recessed CONFIG button on the Marconi TX. The Marconi transmitter
will then broadcast a signal telling all unassigned W-DMX receivers, to assign themselves to this transmitter.
