DMX 512 is

• A. a lighting control system
• B. a data transmission protocol
• C. a power distribution standard
• D. an audio interface

Answer: (A)

DMX 512 is a data transmission protocol used in stage lighting to carry control data from a lighting controller to fixtures and dimmers. It defines a unidirectional serial stream that carries 512 channels per universe, with each channel typically representing a parameter like dimming, color, or position. Data is transmitted at about 250 kbps using RS-485 signaling over standard DMX cables and connectors in a daisy-chained setup, with a terminator at the end. It is not a lighting control system by itself, nor a power distribution standard, nor an audio interface; it’s the data link that lets a lighting console send commands to devices.
