ArcMesh Fixtures Fade Off and On at Regular Intervals


An ArcMesh fixture fades off, then on, at a regular interval of 8-15 minutes.

Description/Explanation of Issue

As of ArcMesh Fixture Firmware 2.3, released June 16, 2020, ArcMesh fixtures will reset themselves to Network ID 0 if they boot up and do not connect to a TX-1 within 15-20 minutes. The intent of this is to make it easy to connect to a fixture that has been programmed to an unknown Network ID.

When a fixture resets itself, it will fade out while it resets. In version 2.3, this will continue until the device connects to a TX-1--at which point the timer will stop. If the TX-1 goes offline, fixtures and drivers will not reset; this timer only starts on boot.


This issue has been resolved in ArcMesh fixture firmware version 2.5, released Februrary 16, 2021. In 2.5 and higher, a fixture already at Network ID 0 will not reboot itself to lost fixture mode.
