The original TurboRay fixtures were manufactured with the "old-style" Display board that will cause DMX errors when trying to convert Artnet to DMX. These fixtures include all Engineering, Demo and Pre-Production fixtures. This applies to any fixtures with a Display PCB with a date code pre-dating 12/14/18
Solution: Install the "new style" Display PCB PN 2591B5714 with date code of 12/14/18
Note: The "old style" PCB only has a single fan header. The "new style" has two and does not require the Y cable.
