DMX512, short for Digital Multiplex 512, is the protocol which digitally managing up to 512 channels via a single data cable. A group of 512 channels is referred to as a Universe.
In the DMX512 framework, each channel comprises a range of 256 steps (0-255), which are allocated to various attributes in lighting fixtures. These attributes encompass a broad spectrum, including colors like red, green, and blue, as well as attributes such as intensity, and pan/tilt positioning. Your lighting fixtures will need to be addressed to a channel or group of channels.
There are some limitations when it comes to using DMX, though some of these can be overcome by using DMX Splitters.
