Kris Posted October 6, 2011 Share Posted October 6, 2011 We recently bought a Strand 200 desk and a Showtec DMX combiner. The plan was to set up a two desk operation in a studio floor and control room. The configuration we were adding to was a single desk in the control room with the DMX out going to a splitter. One of the outs from this go down to Zero88 dimmers on the studio floor and the other two up to a lighting grid to operate some Kinoflos. Initially the combiner was located on the studio floor taking the splitter o/p and the desk o/p with the combiner o/p going to the Zero88s. This worked fine except of course the Kinoflos were spurred off before the send to the floor so the floor desk wouldn't control them. Ok we thought we'll just locate the combiner in the control room and connect it before the splitter and all lights should have dual desk control. When we did this though all sorts of strange things started happening from all lights full on with no faders up to no desk operation at all. Any ideas where the problem could lie - DMX address issue maybe? The combiner/splitter combination shouldn't I wouldn't have thought be an issue.

Kris Posted November 16, 2011 Author Share Posted November 16, 2011 This is resolved now. A splitter that was already in place needed an audio pin config XLR plug Link to comment Share on other sites More sharing options...
david.elsbury Posted November 16, 2011 Share Posted November 16, 2011 Thanks for the update :)Can I just ask for clarification, do you mean that the DMX line needed pins 2 and 3 swapped? David Link to comment Share on other sites More sharing options...
Kris Posted December 14, 2011 Author Share Posted December 14, 2011 Yes exactly that. The splitter was in the original install and all four of it's XLR connections needed to have pin 2 & 3 swapped. I won't name the make but surely that must be a manufacturing fault!? Thanks for the update :)Can I just ask for clarification, do you mean that the DMX line needed pins 2 and 3 swapped?

david.elsbury Posted December 15, 2011 Share Posted December 15, 2011 How exactly does a cable tester test a powered splitter, Ramdram? Link to comment Share on other sites More sharing options...
ramdram Posted December 20, 2011 Share Posted December 20, 2011 Just saw your post. It doesn't. The OP mentioned he found that the fault lay in the cables/connectors. NOT the kit itself, assuming I read the post as intended. I'm presuming he had checked the pinouts between posts #1 & #2. Presume further he must have used either a test meter or cable tester to locate the apparent fault. Perhaps it should be a mantra to ask, first, if the cables/connectors are fully functional so to speak? And wired as applicable. Easy things to overlook, cables.

Kris Posted January 25, 2012 Author Share Posted January 25, 2012 ....just to clarify, the "fault" was on the DMX splitters sockets. To overcome this the new connections made to the splitter needed the pin reversal to audio config. The origanaly installed cables already had the pins reversed. Hence the strange goings on before this was realised Link to comment Share on other sites More sharing options...
