Glossary of Terms
Lighting controller: is an electronic device used in theatrical lighting design to control multiple
lights at once. All lighting control consoles can control dimmers which control the intensity of the
lights. A lighting controller can be a console type processor such as the Pathway Cognito
TM or a
wall controller such as an Easyl TM .
DMX512: is a standard for digital communication networks that are commonly used to control
stage lighting and effects.
Slot: a sequentially numbered byte in a DMX512 packet. Slot 0 is the START Code. Slots 1
through 512 are data slots.
Slot Footprint: the number of data slots used by a product in its operation. Note: A 24 way
dimmer rack may have a footprint of 24, it may be more if some slots are used to provide
additional control functions using NULL START Code packets. Automated luminaires usually
require a Slot Footprint of greater than one.
Universe: a DMX512 data link originating from a single DMX512 source. Control of up to 512
DMX512 data slots comprises a single universe.
Daisy chain: is a wiring scheme in which multiple devices are wired together in series.
RDM (Remote Device Management): is a protocol enhancement to USITT DMX512 that allows
bi-directional communication between a lighting or system controller and attached RDM
compliant devices over a standard DMX line. This protocol will allow configuration, status
monitoring, and management of these devices in such a way that does not disturb the normal
operation of standard DMX512 devices that do not recognize the RDM protocol.
Termination plug: is used when you are using several DMX luminaires on a single DMX line
(Universe). It removes noise and flickering on the DMX line which improves the reliability of the
DMX system. The termination plug contains a resistor to match the cable impedance.
