The Marconi Wireless 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 mounted 'through' connector provided for power. The Marconi LV may be powered by any 4-pin female 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 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 Marconi receiver can listen to any W-DMX transmitter, there has to be a way to tell each receiver which transmitter to listen to. This is accomplished by Assigning or Linking the Marconi to a transmitter. The transmitter assignment information is held in non-volatile memory so 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.
To assign (link, bind, etc.) the Marconi receiver to a transmitter:
Both the Marconi LV and W-DMX transmitter must 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 transmitter.
On the W-DMX transmitter this receiver is to listen to, press and release the configuration button. (This button may be labeled CONFIG, LINK, ASSIGN, FUNCTION, etc. depending on the manufacturer). The W-DMX transmitter will then broadcast a signal telling all unassigned W-DMX receivers, to assign themselves to this transmitter.
If successful, the Marconi LV ASSIGNED and RF LINK indicators will illuminate.
