DMX-512 System

DMX-512 is a digital communication protocol that controls lighting and effects equipment in entertainment and architectural applications. It's the most common DMX protocol and is used to: 

• Control the intensity, color, and movement of lighting fixtures 

• Manage up to 512 channels via a single data cable 

Here are some details about DMX-512: 

Serial communication

The DMX protocol sends a start-of-packet procedure, then a sequence of frames. The bits in the frame are sent 250,000 times a second. 

Channels

A collection of datasets called channels are packaged into a bundle called a Universe. Each Universe has 512 unique channels. 

Values

Each channel can have a value from 0 to 255. 

DMX-512 was originally intended as a standardized method for controlling stage lighting dimmers.
