Paired two sets of MAC 600s the other day (same DMX address). All on back bar - 1 and 3, 2 and 4. Pan reversed 3 and 4.
All working fine - except for shutter channel...
One of the shutters (for each pair) remains open while the shutter value is 0 thru 20 (shutter off command), then, when it goes above 20 (shutter on command), the shutter snaps off on the first one, and the other one snaps on (like normal).
I haven't been down today, so don't know if they have fixed it yet (maybe a firmware config reset will do it) but any help in understanding would be great. It's as though one fixture is detecting its paired with another? But I didn't think there was any space in the packet for reserved bits, and anyway fixtures don't touch the data?
Thanks for your time,
