DMX512 (Digital MultipleX) is a standard for digital communication networks that are commonly used to control stage lighting and effects

DMX512 (Digital MultipleX) is a standard for digital communication networks that are commonly used to control stage lighting and effects. It was originally intended as a standardized method for controlling light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols.

DMX512 does not include automatic error checking and correction, and so is not an appropriate control for hazardous applications, such as pyrotechnics or movement of theatrical rigging.
