Glossary of Terms
Address
A numerical "name" given to a device on a DMX512 line indicating which of 512 possible channels it will respond to.
Align (lamp)
The process of adjusting the lamp within the reflector to obtain the desired output quality of the beam.
Arc Lamp
A type of lamp which creates light by forming an arc of electricity. Brightness is achieved by including gasses and
metals within the envelope of the lamp which dissolve and give off a bright light. Arc lamps must be dimmed
mechanically because electrical dimming will extinguish the arc.
Art-Net
Protocol for sending DMX512 data over IP networks.
Attribute
An individual controllable aspect of a luminaire: pan, tilt, color, etc. Also known as "parameter."
Beam
1) The size, shape and sharpness of image of the light beam as projected on stage.
2) A function of the luminaire related to the size, shape, and sharpness of the light beam, specified by beam and
edge data, and use of gobos (patterns) as required.
Channel
