Electricunderpants Posted August 21, 2007 Share Posted August 21, 2007 I work part time at a local school theatre which has 4 dimmers in the usual daisy chain set up. But instead of terminating at the last dimmer it continues on to a small box on the wall. Any ideas what this is? and is it safe to unplug it because I want to run some intelligent fixtures from dimmer#4. Link to comment Share on other sites More sharing options...
Ike Posted August 21, 2007 Share Posted August 21, 2007 Could be anything from a dimmer for the house lights, a terminator or a bit of cable going somewhere else. Any chance of a picture? Link to comment Share on other sites More sharing options...

I think you need to expand slightly on this bit I only have one photo which doesn't clearly show the box in question and I won't get to theatre for a couple of days to get a good photo (sorry). The fixtures I want to runare a couple of cheap scanning barrel rollers so I can put a few gobos on the back wall of stage. Link to comment Share on other sites More sharing options...
mbthegreat Posted August 21, 2007 Share Posted August 21, 2007 Can you open up the box and see what it does? Link to comment Share on other sites More sharing options...
gareth Posted August 21, 2007 Share Posted August 21, 2007 because I want to run some intelligent fixtures from dimmer#4.I think you need to expand slightly on this bitReally? I thought the OP explained that aspect of his problem quite clearly - he wants to use the DMX loop-through from the fourth dimmer rack to feed some moving lights. That's how I read it, anyway.

lightsource Posted August 22, 2007 Share Posted August 22, 2007 Sorry Gareth, You may have read it that way, but I read because I want to run some intelligent fixtures from dimmer#4. Now translating as it actually reads....... Maybe the OP should have explained a little bit clearer :) Link to comment Share on other sites More sharing options...
mumbles Posted August 22, 2007 Share Posted August 22, 2007 because I want to run some intelligent fixtures from dimmer#4. Now translating as it actually reads....... Maybe the OP should have explained a little bit clearer :)If the OP had said control some intels from the dimmer then yes, but I struggle to see how anyone who knows who DMX is used would translate it as you say. Definitely I would describe the loop through the intels beyond the dimmers as the OP did. More in topic, if you unplug the lead from the box, run cabling to the scanners and then run it back again into the box you should be fine (as you would then have 6 devices on the line). If you open the box up and find it to be just a terminator, then this would remove the requirement for a return run of cable, as you could insert a termination at the end of the chain in the last scanner.

Electricunderpants Posted August 22, 2007 Author Share Posted August 22, 2007 Thank You Mumbles that's all I wanted to know.Your translation was correct. My apollogies to others for my lack of detail in original post. Link to comment Share on other sites More sharing options...
zonino Posted August 22, 2007 Share Posted August 22, 2007 but I read because I want to run some intelligent fixtures from dimmer#4. Now translating as it actually reads....... Maybe the OP should have explained a little bit clearer ;) it was pretty obvious what the OP meant... anyway, is running a line back from the last fixture into the wall socket an option?

Jivemaster Posted August 22, 2007 Share Posted August 22, 2007 It really depends on what the box does! It could be simply a box with the terminator inside or it could have a real function. If you can look.... Either take the DMX for the barrels from dimmer 4 then back to the box (or ignore the box if its a terminator - use a terminator plug in the last device. OR get a DMX isolated splitter put it in anywhere and run the barrels off that. There is value in having the terminator screwed to the wall in a school, -it's less likely to walk off!

ceecrb1 Posted August 22, 2007 Share Posted August 22, 2007 oh MY god, why is everyone arguing over what COULD be... why not just wait till OP returns instead of resorting to the usual, whos the most wrong competition? Link to comment Share on other sites More sharing options...
bruce Posted August 22, 2007 Share Posted August 22, 2007 You really need to know what's inside the box. Of course, the solutions given above (looping through your new fixtures and gthen going back into the box) are technically correct, but if the "box" goes off to some other piece of active equipment (maybe houselights?) and you don't know how they're set up, you're going to have fun when you try to decide on appropriate DMX addresses....

David Lee Posted August 22, 2007 Share Posted August 22, 2007 Just unplug it from the wall and see what doesn't work afterwards. No need to take boxes apart. Link to comment Share on other sites More sharing options...
