Basic Definitions
- Fixture/Slave: Any object that takes DMX input. Receives a full DMX packet, picks out and listens data relevant to itself (intelligent lights, gobos, lasers, and fog machines). Most Fixtures have an output channel that is simply a copy of the input.
- Universe: A Universe consists of a set of fixtures all strung together reading the same data. A Universe contains 512 bytes of information, so the amount of fixtures in a universe will depend on how many bytes of data are needed to address each fixture.
- Controller: Creates and sends DMX data to one or more Universes. Usually, this a large board with many knobs and sliders, however, a simple PC can be used as a DMX controller.
