Terminology / Control / DMX

DMX512

A digital lighting control protocol originally developed by USITT. Transmitted over twisted-pair cable with 5-pin XLR connectors, the control protocol carries control data for up to 512 channels. Traditionally channels where dimming channels, however in current use a channel is parameter of a lighting (or other) fixture. Widely used in stage lighting and video control systems, multiple DMX512 universes can be combined to provide control to larger and more complex fixtures and devices.
