DMX requires a controller to
define and send the values to each channel. A controller can be as simple as a
laptop with software and an adapter.
Professional lighting-control consoles,
or desks, allow for complex programming of lighting setups and create
intricate cue lists to define sequences
of lighting effects and transitions.
(Professional desks common in the
industry include GrandMa from
MA Lighting, Hog 4 from High
End Systems, Insight from ETC, and
Vista from Jands.) Dimming units
are the most common DMX boxes.
Professional dimmer racks control the
light intensity of dozens of fixtures by
changing the voltage to each unit. As
illustrated, dimmer racks will have one
channel allocated for each fixture
output.
Automated lights, or moving
heads, offer advanced functions, notably
motorized control of movement, shuttering, color and gobos. Automated
lights use HMI bulbs with high-quality
optics to deliver sharp, powerful beams.
Mechanical shutters allow for dimming
without color-temperature change,
while internal filters enable a rich array
of hues. Custom gobos can also be
added. Automated-light manufacturers

Top: This diagram shows the DMX stream and a sample DMX daisy-chain network.
The DMX stream is a series of values for each of the 512 channels and repeats up to
44 times per second. Middle and bottom: A 30K dimmer with a 20K fixture.
