Channel Boundaries

This section describes the relationship between DMX address and fixture number, and explains how to mix
fixtures using DMX modes 1 or 2 with DMX mode 3 on the same link.
Overview
DMX 512 protocol provides 512 channels that are divided among all the fixtures connected to the controller
in a particular link. The number of channels that a fixture uses depends on the requirements and design of
the fixture. In theory, you could have one fixture that uses 512 channels, two fixtures that use 256 channels,
four fixtures that use 128 channels, up to 512 fixtures that use one channel each.
Each Cyberlight fixture uses a contiguous block of channels with each block having a unique starting
address. The block of channels assigned to each address defines its channel boundary. Channel boundaries
can start at any address, even or odd. The exact address depends on the fixture's addressing scheme.
Cyberlight DMX modes 1 and 2 are each on 20-channel boundaries while mode 3 is on a 15-channel
boundary.
