DMX DMX512(1990) a specification for communication
between control desks and Fixtures, Originally for
Dimmers it has been adopted as a control protocol
for most Intelligent Fixtures. It can carry 512
different Channels of data.
FADE A continuous transition from one level to another.
FIXTURE Any lighting instrument that is patched using a
Personality. Generally refers to a moving light or
colour changer, not an individual Dimmer channel.

have two possible Pan and Tilt positions for each
point on stage, and FLIP will alternate between them.

FUNCTION WHEEL A wheel which does not directly control an Attribute
channel on a fixture, rather it controls only part of an
attribute and another function wheel may control
other parts. For example a rotating gobo attribute
may have one function wheel to control continuous
or indexed mode, and another function wheel to
control rotation speed or position, though the actual
fixture only uses one DMX channel to control both
these functions.
