Glossary of Terms
Address
A numerical "name" given to a device on a DMX512 line indicating which of 512 possible channels it will
respond to.
Align (lamp)
The process of adjusting the lamp within the reflector to obtain the desired output quality of the beam.
APS6
Module
The lamp power supply (ballast) for arc lamps found in the VL5+ Series Luminaire.
APS6 Trunk
Cable
Multi-conductor cable used to provide six circuits of arc lamp power to VARI
❋
LITE Series 300 luminaires.
Differs from industry standard six circuit Socapex cable by using pin 19 as a shield to eliminate RF noise,
which can interfere with sound systems. (Can be used with incandescent lamps.)
Arc Lamp
A type of lamp which creates light by forming an arc of electricity. Brightness is achieved by including
gasses and metals within the envelope of the lamp which dissolve and give off a bright light. Arc lamps must
be dimmed mechanically because electrical dimming will extinguish the arc.
Attribute
An individual controllable aspect of a luminaire: pan, tilt, color, etc. Also known as "parameter."
Beam
1) The size, shape and sharpness of image of the light beam as projected on stage.
2) A function of the luminaire related to the size, shape, and sharpness of the light beam, specified by beam
and edge data, and use of gobos (patterns) as required.
C3 Dimmer
The VARI
❋
LITE current sensing dimmer that can be installed in a Modular Rack SixPack chassis to control
the intensity of a VL5, VL5+, or VL5B wash luminaires.
Channel
A control reference which collects a device’s associated thumbwheel address(es) (device, lamp power, etc.)
and maps them to a single selectable number. Channels are assigned via the patch setup. (Also referred to as a
"Control Channel.")
Console
Timing
Time value in seconds or minutes applied to an entire cue.
Dimmer
Device used to control the relative output (or intensity) of an incandescent lamp.
DMX512
Digital multiplexing; an industry standard protocol. 8-bit protocol with a maximum of 256 steps of resolution
per channel. Maximum of 512 controllable channels per DMX data stream.
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.
DMX512
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.)
