Glossary-4 Trackspot User Manual
MSpeed
A means of defining the time it takes for a motor to move to a
different defined position.
Operating mode
A setting that controls a fixture’s specialized function (such as
Auto Dim Override and Lamp Save) while the fixture is
configured for a control mode. There are two operating
modes, Self Test and Setup (Focus), which override incoming
data from a controller.
Optical sensor
A piece of equipment using an infrared beam that “senses” the
homing slot on a wheel to determine the wheel’s home or
starting point.
Optimize
The process of positioning a lamp inside its reflector to achieve
the brightest possible light output with the brightest point of
light in the center of the beam. An optimized lamp prevents
the beam from damaging other internal components inside the
fixture.
QT 8500
A lamp specifically designed for use with Trackspot. This
lamp combines affordability, long lamp life (300 hour average),
reliability, high output, and stable color temperature
throughout the life of the lamp.
Starting channel
The first channel in a specific block of contiguous channels
used by a fixture in DMX 512 protocol. For example, in a link
of Trackspot fixtures, the second fixture would use channel 8
as its starting channel due to Trackspot’s 7-channel block
structure.
Terminator
A terminator is a resistor inside an XLR connector. It is used to
prevent the digital data from continuously “echoing” up and
down the data link. A terminator must be used on the last
fixture in every link, except for those fixtures controlled by
standard analog control. For instructions on constructing a
terminator, see “Constructing Terminators” on page 2-11.
