Socapex
Cable Industry standard multicore cable is used to distribute lamp power to luminaires. It is often created using 19-
pin Socopex or Veam connectors and 12/18 cable for six 20A circuits.
Splitter
(Isolator) Device used to optically isolate and split a DMX512 signal. Note: A DMX "two-fer" cannot be used to divide
a signal.
Start To energize a luminaire arc lamp (applies to arc-lamp luminaires only).
Tails In the case of Series 300 equipment, 2/0 double-insulated wire, rated at 225 amps, with 4\0 Cam-Lok connec-
tors on one end color coded by phase, neutral and ground and bare wire on the other, or 8/5 multicore wire
with a female connector (Hubbell or Epic) on one end, and bare wire on the other.
Terminate/
Termination Termination refers to the dampening of DMX512 signal at the end of the transmission line. Termination is
created by placing a 100 ohm resistor between pins 2 and 3 of the DMX512 line. Often, there is a switch on
DMX512 devices to do this internally. If not, a terminator is provided in the form of an XLR connector with
the proper resistor between pins 2 and 3 to be placed in the DMX Thru port on the device.
Test
Software Software resident in the Smart Repeater unit that allows for troubleshooting of a Series 300 luminaire.
Three-
Phase Power In order to manufacture electricity efficiently, it is created in what is known as three "phases". In other words,
in its creation, the sine wave of alternating current are offset by 120°. The VARI
❋ LITE system runs on three-
phase power, as indicated by the five Cam-Lok connectors on the mod rack - Phase X, Phase Y, Phase Z,
Neutral and Ground. Each phase in a 200A feed can support 200A of equipment. To adequately power the
same amount of equipment on a single phase, you would need a 600A feed.
Thumb-
wheel Switch Three digit switching device used to set the range of channels a particular Smart Repeater unit or other
Series 300 hardware device looks at for control information. Also used to set the operating mode of a Smart
Repeater unit.
Tilt The movement of the luminaire around the axis of the tilt tube; 270° for the VL5 wash family and the VL6
and VL7 spot luminaires, and continuous in either direction for the VLM Moving Mirror.
Time Control of the duration of the change of the variable parameters of VARI ❋ LITE automated luminaires and
other devices in a lighting system.
Timing
Channel A Timing Channel is used in lieu of cue fade rate to determine the time it will take a luminaire to move from
one setting to another. For example, a cue in which a luminaire pans from one side of stage to the other may
look "steppy" if cue fade rate is used, because of the nature of the DMX512 signal. To overcome this, a
timing channel causes the Smart Repeater unit and luminaire to calculate the move in time, effectively
smoothing out the movement. To operate properly, the new position and timing channel levels need to be sent
to the Smart Repeater in a zero count, (an instant change).
VARI*LITE
Color
System The default color palette, available via the Color Soft Select or control keypad, which is based on a
numbering system for VARI*LITE colors.
Zero
Position Pan and Tilt values at 50%. Also called "Home Position" or a "50/50" cue or group.
