To design a show for Chauvet Geyser RGB Fog Jet fixtures, please follow the steps in DMX basic instructions and Light fixtures basic instructions.  If you don’t already have a compatible firing system or controller capable exporting a DMX script, please refer to Supported firing systems and controllers (DMX) for the list of available hardware options.


Choosing the DMX channel ranges for fixtures

Each fixture requires multiple channels, so if you are putting multiple fixtures in the same DMX Universe, you need to set the Start Address on the fixture in the real world and the corresponding DMX Channel Base on the fixture in Finale 3D to a range of channels that doesn’t overlap with others.  A DMX universe has channels 1-512.  If you want to pack as many fixtures into the 512 channels of a DMX universe as you can, back-to-back ranges are the most efficient.  Table 2 shows an example for 8-channel fixtures.  Some DMX firing systems and controllers only support 50 or 100 channels, so you may not have all 512 channels to work with.
