DMX512 (Digital Multiplex or DMX for short) is a standard for digital
communications used to control stage lighting and effects. It's been around a
long time, but is simple and very reliable.
A series of 512 bytes of data is constantly sent over a shared bus line. Each of
these bytes is a 'channel' and starts with channel 1. The last channel being 512.
Devices (like lights) on the bus line are assigned addresses. The address is
what 'channel' the device needs to look at. Devices can and most likely will look
at several channels. So a 3-channel light assigned to address 4 will look at
channels 4, 5 and 6.
