Our church had a lighting hit several months ago. It took out a Fleenor splitter and 2 of our 4 Autoyokes with SourceFour fixtures. Had boards and/or units rebuilt.
The autoyokes are hung from ceiling - 2 on each side of booth. Each side has the 2 units chained and fed from an existing dmx recptical. Both units that went out were first in line.
I tested each repaired unit by connecting it directly to our ETC expression III. Both worked. We then then rehung units - 30 ft up with a ladder. On one side both untis work. On the other side the first in chain (repaired unit) goes thru home sync but wont respond to DMX. The second in chain works. By removing jumper to second unit, first unit starts working. By sending DMX first to second unit and then to first (bypassing first unit's DMX ouput port) - same result first unit wont work second one will.
No they are not terminated. No as built wiring diagrams and we have several hunded fixtures. DMX wiring appears to be cat5.
Even with all the above - I can't explain why it used to work and now doesn't.
Plan to recommend we run real DMX cable from splitter (have unused port available) and daisy change just Autoyokes with terminator.
Any ideas to get unit going until rewiring would be appreciated.
Thanks
