<div dir="ltr">Thanks for all the suggestions.<div><br></div><div> I experimented by creating a new show file, creating a 1 to 1 patch. When I tested the circuits,(remembering that only about 1 in 5 circuits has a fixture plugged, the dimmers/circuits seemed to react as expected. When I reached address 97 through 102 the architectural lighting (from the labeled 2nd rack that I found) that I can see (some are backstage and not visible from the booth) reacted as expected. Above that,103... etc lights labeled in an architectural panel containing what seem to be relays activated fluorescent worklight, aisle lights & some backstage lights.<div><br></div><div>But, the few lights that are connected to catwalk circuits labeled 97 through 120 were NOT independently controlled. I did NOt notice whether they might have energized when I activated addresses 1 through 24.

Dimmer doubling is a possibility, but should give you 192 circuits, not 120.</div>

Is it possible there's a second rack (perhaps disguised as an architectural or relay rack) that's driving those additional 24 circuits? Or perhaps some lights -- front of house or in the pit -- are driven by a separate rack?</div>

<b>Subject:</b> [SML] ETC Sensor Dimmer rack running 120 circuits</font>
<div> </div>
</div>
<div>
<div dir="ltr">As you may know, I began my return to educational theatre last week at a small university in central Iowa and have run across something that I am confused about regarding the lighting system. It appears to be an older ETC system with a single
Sensor rack (96 dimmers). However, we are somehow driving discrete 120 circuits (there are a couple that are labeled as duplicates, but not enough to account for the 24 extra circuits)
<div><br>
</div>
<div>Can anyone explain how this might work?
