  UV-DMX
The UVI-48 Ultraviolet Illuminator is a state of the art lighting instrument based on an array of 48 Ultraviolet LED's and a computer micro-controller.
Illuminators may be controlled by any DMX lighting system for professional displays, or may be set up for independent operation at a preset intensity or strobe rate in stand-alone UV lighting applications.
For replacing existing fluorescent or incandescent UV light sources, 395 nanometer UV LEDs may be installed to duplicate the deep blue-violet output common to those fixtures.

 About DMX-512 lighting protocol - Pangolin Laser Systems
There are five pins on a DMX connector: a wire for ground (cable shield), two wires for "Primary" communication which goes from a DMX source to a DMX receiver, and two wires for a "Secondary" communication which goes from a DMX receiver back to a DMX source.
DMX devices such as lights are connected in a daisy-chain fashion: from the controller to light #1, to light #2, to light #3 and so forth.
But improvements in technology have reduced the load a single light puts on the circuit, so you may be able to drive as many as 128 lights (each one being 1/4 load) from a single controller such as the QM2000 board.

  Backstage Technical Services | Lighting Guide | What is DMX?
Traditionally, when electrical lighting control systems were developed for the theatre, the three components of the system (console, dimmers and lights) where linked together on a "one wire per channel" basis.
DMX512 (the 512 represents the number of channels one DMX cable can carry) requires only one 3-core (on older systems, 5-core DMX outputs may be seen - two cores are not used) shielded cable, terminated with XLR connectors, to get all the data channels from the console to the dimmer.
DMX is advantageous because the DMX cable is less bulky than a 48-way multicore and is therefore cheaper and less cumbersome.

 Dove Systems - Lighting control for theatre, television, church, school, & clubs.
DMX is a multiplex technique that uses only four conductor shielded cable to control up to 512 dimmers.
DMX sends a series of numbers starting with a special number called the start code, then up to 512 numbers representing the levels of each dimmer starting with dimmer one.
DMX receiving equipment should have a "terminator" switch or termination option for end of line in the setup.

 DMX Guide: High Energy Lighting & Sound. Dj equipment
Before DMX was created, the only lighting control system was analog which required one individual wire to be run from the controller to each light fixture or dimmer pack.
DMX is now recognized world wide as the standard communication language for theater and night club lighting and now even some fog machines.
A DMX system has 4 basic parts: A controller that creates and sends the signal, the cable that carries the signal, the light fixtures or dimmer packs that receive the signal and a terminator to stop the signal.

 DMX Control
That's the power of DMX - since the lighting fixture gets to decide what to do with the number that it is given, you can control almost anything - laser scanners, fog machines, mirror balls - just name it, and somebody probably has it running on DMX.
DMX has no error detection or correction, so it is possible that a glitch in the transmission might accidentally turn on something when it isn't yet ready.
DMX signals must travel in a straight line, from the control console on one end, to one unit, then another, to the end.

 Smart Lights (January 2002)
DMX is actually a 512-channel digital multiplex data transmission standard for controlling theatrical lighting dimmers, but it has been successfully adapted for other applications by the lighting industry.
DMX signals are used for much more than just turning lights on or off; intelligent DMX systems can provide total control of lighting colors, gobos, movements, and speeds.
Light Jockey (which may be downloaded for free at www.martin.dk) also includes an indispensable off-line “visualizer”; users can use this function to create a virtual banquet hall, “load-in” various lights, and see what it’ll look like the night of the event.

 Backstage Technical Services | Lighting Guide | DMX and patching
Before DMX, in the days when multicore analogue systems were prevalent, the console was physically connected on a channel by channel basis to the dimmers.
If you wanted to group a set of lights that were spread around the rig on different circuits, you had to perform a "hard patch" where "circuit tails" were plugged into dimmer outputs.
The DMX soft patch system allows you to do this because the one-to-one patch is not hardwired as it would be in an analogue multicore system.

 Ukslc.org - Articles - Lighting - How to set up and address DMX lighting
If the last fixture in the line has a DMX termination switch it should be set to on, all other fixtures in the chain should have this switch in the off position.
You will need to use a DMX termination plug for fixtures without a built in terminator, this is simply a male XLR connector with a 120 Ohm resistor between pins 2 and 3.
Switch 10 will not normally be used for the DMX addressing, although may control other aspects of the fixture such as switching between DMX or stand alone mode, or may be used to switch in a termination resistor.
