DMX512 REFERENCE GUIDE 151
DMX/DMX512
The universally accepted lighting control protocol in the entertainment industry. A console uses this protocol to
control specific devices in a lighting system. A DMX512 data channel is eight bits of absolute parameter data. A
DMX512 data packet is a group of 512 data channels, over a value range of 256 steps.
DMX512 Cable
Industry standard cable consists of two twisted pair and a shield, and 5-pin XLR style connectors. The pin out is: pin
1 = common (shield), pin 2 = data -, pin 3 = data +. The second pair (pins 4 & 5) may be used for a secondary data
link; in VARI
❋
LITE equipment, these pins are not used.
DMX Power Pack
The DMX Power Pack (DPP) is a portable electronics chassis that provides lamp power and control to Series 300
luminaires.
DMX Universe
A group of up to 512 DMX channels. Consoles may have more than one universe, usually labeled in groups of 512.
Douse
To de-energize a luminaire lamp. (Douse is unrelated to intensity states.)
Epic Connector
A six-pin, three-phase 35 amp connector found on 8/5 wire used to provide power to a SixPack chassis. Also found
on the back of a mod rack.
Fan-In
(Break-In) 6 male plugs to female multicore connector. In the case of Series 300 equipment, a Socapex connector.
Fan-Out
(Break-Out) A male multicore connector to 6 female plugs. In the case of Series 300 equipment, a Socapex connector.
Feeder
In the case of Series 300 equipment, 2/0 double-insulated wire, rated at 225 amps, with 4\0 Cam-Lok connectors on
either end, color coded by phase, neutral and ground.
Fixture Orientation
Based on the direction the pigtail points as it exits the fixture.
Flipped Focus
When one or more fixtures inadvertently move differently from others in the system.
Focus
The point to which the light beam is directed. Also, a function of the luminaire related to the direction of the beam as
specified by pan and/or tilt data.
Frame
A luminaire mechanism which allows framing of the light beam.
Gobo
A pattern (template) used to create backgrounds or texture when projected on to scenery or cycloramas, or to create
the illusion of natural elements such as fire, windows or tree leaves.
Hard Reset
Restarts luminaires and reloads operating system and cue data.
Home Position
Pan and Tilt values at 50%. Also called "Zero Position" or a "50/50" cue or group.
