Instructions
To design a show for Anonymous Small Steel Gun 120W Moving Head Gobo Spotlight 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 16-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.

Programmer notes
The color and gobo mechanisms of these fixtures require careful programming of the DMX Patches. Programmers who are implementing effect libraries may benefit from these notes:
- DMX Patches for one-shot “Flash” effects set the color in setup phase because the color wheel needs to move to the correct rotation in advance of the effect to be prepared. Otherwise the audience sees the color wheel spinning to the correct color at the beginning of the effect. The setup phase in the DMX Patches is a luxurious one second by default, but since it compresses against any previous effect rather than overwriting the previous effect, the luxury has no consequence.
