Title: Using terminal strips for DMX wiring
Post by: tatersav1 on April 17, 2009, 06:47:28 PM

I am wiring a church for both audio and DMX lighting control. Can I run a shielded twisted pair from the controller to a terminal strip and then go to the lighting dimmer. The ends are the normal red 20 gauge terminal lugs that you crimp on the individual wires just like microphone cables. The terminal strip is one like is used commonly for audio installations. There would be three terminals one for pos, neg, and shield .

I would think you certainly can, and it would probably work, but I would not recommend it because its nonstandard.  Is there some reason why you need to do this?  There may be an alternative answer...

Yes there is a reason. All of my audio lines from the sound booth in the back of the church run about 100 feet to a room behind the stage via a 42 channel audio snake. In that room all of the 42 channels go to terminal strips mounted in a junction box. From there individual twisted pairs leave the terminals and go to the individual stage boxes spread out all over the stage. These boxes are used to plug in microphones, musical instruments, amplifiers, etc. I could send the DMX signal through one of the 42 channels in the audio snake. They are twisted pair and have great shielding.  I could then go from the terminals to the dimmer using one twisted pair.
