Doug Fleenor Design Marconi LV - Manual

Marconi LV Wireless DMX Receiver
The Marconi W ireless DMX Receiver (Marconi LV) receives all 512 channels (one universe) of
DMX512 using 2.4 GHz spread spectrum technology. Power in and DMX out are provided on 10"
pigtails with a chassis m ounted 'through' connector provided for power. The Marconi LV m ay be
powered by any 4-pin fem ale XLR port (LED or Color Scroller power supply) that uses pins 1 and
4 for power, or by an optional 'wall wart' adapter. The power 'through' connector passes all four pins
through so the user does not lose the use of the XLR port from which power is taken.
Marconi products use the W -DMX system (invented by W ireless Solutions in Sweden) which allows
up to 16 transm itters and any num ber of receivers to be used sim ultaneously in a single venue.
Since any Marconi receiver can listen to any W -DMX transm itter, there has to be a way to tell each
receiver which transm itter to listen to. This is accom plished by Assigning or Linking the Marconi to
a transm itter. The transm itter assignm ent inform ation is held in non-volatile m em ory so if the user
has only one W -DMX transm itter (or keeps his system s separate), the configuration process
described below will only have to be done once.
To assign (link, bind, etc.) the M arconi receiver to a transm itter:
Both the Marconi LV and W -DMX transm itter m ust be powered up and within range of each other.
Using a paper clip, press and hold the recessed CONFIG button on the Marconi LV until the ASSIGNED indicator goes off
(about 5 seconds). This will unassign the Marconi LV from any other transm itter.
On the W -DMX transm itter this receiver is to listen to, press and release the configuration button. (This button m ay be labeled
CONFIG, LINK, ASSIGN, FUNCTION, etc. depending on the m anufacturer). The W -DMX transm itter will then
broadcast a signal telling all unassigned W -DMX receivers, to assign them selves to this transm itter.
If successful, the Marconi LV ASSIGNED and RF LINK indicators will illum inate.
