High End Systems LED Lighting Fixtures Intermittently Twitch When Connected to Data
Symptoms/Issue
Fixtures will twitch occasionally. Examples of the twitching can include a quick and minimal pan/tilt movement, output blinks, a quick slight movement of gobo/color/animation wheel or any other function in the fixture.
Description/Explanation of Issue
An outside source is causes fixtures to twitch due to intermittent data signals.
This is a different issue from when fixtures receive data and RDM simultaneously. Refer to the RDM article under Related Links below
Fix/Solution
- Ensure the DMX refresh rate is set to maximum on consoles and any peripherals on the data link.
- If twitching still occurs then the fixtures and console must be isolated from other peripherals on the data link such as a node, switch, router, etc.
- Run a data line directly from the console to the fixture for testing.
- Once it is determined that the fixtures no longer twitch then troubleshooting steps need to be taken on the peripherals
