This helpful handbook is designed to provide a basic understanding of the DMX 512 protocol, including theory of operation, proper equipment use, and some basic application examples.

DMX is an acronym for Digital Multiplex, a communication protocol (a set of rules) used to remotely control lighting dimmers and intelligent fixtures. It is designed to provide a common communications standard between these lighting devices regardless of the manufacturer. 512 refers to the number of control channels used on one network segment (often called a ‘universe’) of devices. In a simple dimming system, one channel controls the intensity of one dimmer. A single intelligent fixture, however, may require several channels to control its various parameters (one channel each for pan, tilt, color, gobo, etc.).
