Which control protocols should festival laser systems use?
Direct answerUse ILDA for graphic playback, DMX512 or Art-Net for console integration, and add redundant control links so a single failure cannot stop the show. Sync effects to audio with timecode.
Protocol Roles on a Festival Rig
| Protocol | Function |
|---|---|
| ILDA | Graphic and animation playback from the laser software |
| DMX512 | Integration with the festival lighting console |
| Art-Net | Network control across stages and distant fixture positions |
| Timecode | Keeps laser cues aligned with the audio playback |
Redundancy Planning
- Run a second control path over a different cable route or network segment
- Keep a standalone show file on the laser controller in case the console fails
- Test the switchover procedure during rehearsal, not during the show
- Document the fallback look so any operator can trigger it
A redundant control path is the cheapest insurance against a show-stopping failure at an outdoor festival.
