DMX512 REFERENCE GUIDE 153
SixPack Chassis
Case used for lamp power distribution. Each chassis can contain up to six modules - APS6 and/or C3 in any
combination. Each slot in the chassis corresponds to an output port on the Smart Repeater unit. The SixPack Chassis
connects to the Smart Repeater unit through an APS Cable or standard Socopex cable (if no APS6 modules are
used).
Show File
A file containing all programmed cue data.
Shutter
A mechanism which controls the douser or strobe action of luminaires capable of this function.
Smart Repeater
The Smart Repeater unit is the hub for up to six Series 300 luminaires. The Smart Repeater unit s also an interface
between the control system and the luminaires. It consolidates the three things necessary to run Series 300 luminaires
into one lamp cable: Control Signal, Lamp power and Motor/Control power.
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 connectors 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.
Thumbwheel 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.
