DMX-512 (Digital Multiplex) is an open, serial (RS-485) standard communication protocol that has been used for controlling lighting dimmers and fixtures. It is designed to provide seamless communication between lighting end-points regardless of their manufacturer.

It is widely used for controlling stage lighting and theatrical effects such as moving lights, color changing LED applications, fog machines, etc. DMX has also penetrated in non-theatrical interior and architectural lighting.
