Hal, I saw your answers to my electrical questions in this thread:  http://forums.prosoundweb.com/index.php/topic,139517.msg1296656.html#msg1296656


Yes, your question sounded very familiar.
 
As for the DMX you can use any plenum listed 22 ga 2 pair (shielded?) cable. That can be run through the walls and ceiling just as it is. Type CMP or CL2P is what you want. You do want to keep it separate from the line voltage in that you can't run it through the same ceiling boxes. It must be brought out of the ceiling separately, perhaps a matching plate with a hole in it with a bushing. I suppose if you wanted to get fancy use a plate with an XLR with a patch cord or jumper from the plate XLR to the fixture XLR.

Thanks Hal, that's exactly the answer I was looking for.  I appreciate the help.

However, it should be noted that if you are running inside a rated wall assembly or penetrating through a rated wall or ceiling then any penetrations have to be properly addressed such that the rating of the wall or ceiling is maintained.  That might typically require a conduit stub of sufficient length or appropriate fire sealant.

Understood.  Thanks for the direction.
