Glossary
Record - See Program.
RDM - Remote Device Management
is an industry standard communica-
tions protocol which uses the DMX
link for bi-directional communication
with devices such as dimmers and
moving lights.
S
ACN - Streaming ACN – A DMX
over Ethernet standard support-
ed by the ZerOS consoles.
Save - See Program.
Scene - A defined look on stage,
achieved by a combination of chan-
nel and fixture output levels from the
desk.
Scroller - A device which fits on the
front of a lamp, comprising of a roll
(scroll) of different colored filter gels,
which are positioned by motors so
that the color can be changed by
remote control, usually DMX.
Size X/Y - The X and Y size of a
Movement Effect. The X and Y size
of a Movement Effect are controlled
by the wheels when the appropriate
POSITION wheel group is selected
for a fixture with Pan & Tilt. Setting
one of these to 0 on an Ellipse effect
creates a horizontal or vertical line.
Slider - See Fader.
Snap - A fade which happens
instantly.
Snapshot - A mode of the DMX
Input, where the instantaneous levels
of all 512 DMX channels are stored
into the memory or submaster being
recorded.
Solo - A channel is at full intensity
(subject to the Grand Master) and all
other channels are turned off. This is
a temporary action generally associ-
ated with a flash button.
Patch - A link between a desk chan-
nel and a DMX channel. A nominal
1:1 patch is applied on all consoles
when they are delivered, but this can
be configured by the users.
PC - Personal Computer – This
needs to be running Microsoft Win-
dows® to use the Fixture Type Editor
and Lighting Consoles tools supplied
on the CD with the Lighting Console.
Personality - Fixtures sometimes
have multiple personalities or modes
which can be set on their menus
or using RDM. It is very important
when using fixtures to make sure
that the mode set on the fixture is
the same as that on the desk.
Ping-Pong - See Bounce.
Playback - Another name for the se-
quential memory stack. Also known
as a Cue Stack.
Pot - A potentiometer, which can be
turned to set various values between
a given range.
Preset - In this mode, channel fad-
ers control individual channels and
can be crossfaded using the A and
B Masters. In 2-Preset mode, the
PROGRAM/GO button is inactive.
Preset Mode can be expanded to
Wide Mode, when the PROGRAM/
GO button functions as a Store
button.
Preset Focus - See Palette
Program - Refers to storing a scene
or chase as either a submaster or a
memory.
PSU - Power Supply Unit. The ex-
ternal box of electronics which alter
the supplied power voltage into the
correct settings.
R
ate - Another name for Speed.
How fast a chase is running.
Modifiers - Often used to describe
the options available within a chase.
The chase modifiers are Attack,
Direction, and Speed.
Multi-Part - Some fixtures require
more than one DMX Address. This
is most commonly found with a
Lamp + Scroller fixture, where the
lamp will have one DMX address (set
on the dimmer controlling it), and
the scroller will have another DMX
address, either set on the scroller
itself, or on the scroller control unit.
N
otes - Part of the MIDI system,
whereby a specific note can trig-
ger a preset or submaster.
O

Movement Effect is controlled by the
wheels when the appropriate POSI-
TION wheel group is selected for a
fixture with Pan & Tilt.
P
alette - Palettes are small bits
of memory which can be used
as building blocks for your show.
Palettes are useful both for busk-
ing a show using easily accessible
pre-set looks, and for allowing for
edits to commonly used looks to be
made only in one place. For exam-
ple a touring show built on position
palettes, in each new venue only the
position palettes would need to be
updated, and then any memories or
submasters which referenced them
would automatically take the up-
dated position.
Pan - The left-right movement
parameter of a fixture (c.f. Tilt). Can
be automatically controlled with a
Movement Effect.
Parameter - An individual function
within a fixture, controlled by one or
more DMX channels (e.g. Dimmer,
Color, Gobo, Focus, Pan, Tilt etc).
