Synonymous with "fixture".
The native control protocol for Cyberlight, LWR offers all the features of DMX 512 plus it
gives you the ability to perform software uploads using a High End Systems Link Card or the
Cyberlight Upload Module.
MSR stands for Medium Source Rare Earth and describes the family of arc lamps used in the
Cyberlight. Rare earth elements (such as Dysprosium and Holmium) are added to metal halide
to give the lamp a more continuous spectrum.
MSD stands for Medium Source Daylight. ("Daylight" is a reference to the fact that the lamp
has roughly the same color temperature as ordinary sunlight.) The MSD lamp has basically the
same composition and the same color temperature as the MSR lamp, but it has a lower light
output and longer life.

See "Lamp strikes".
The creation of colors by filtering out (subtracting) certain wavelengths from a typically white
(multi-wavelength) light source. For example, putting a magenta filter in the path of a white
light source subtracts green light. This is the color mixing model used in Cyberlight.
Typically, the filters used in a subtractive color mixing system are cyan, yellow and magenta;
thus, this is usually referred to as the CYM color mixing model.
See also "Additive color mixing".
A terminator is a resistor inside an XLR connector. It is used to prevent the analog signal from
continuously "echoing" up and down the data link. A terminator must be used on the last
device in every DMX link. Instructions for constructing a terminator can be found in the
section titled "Terminators" on page 2-7.
