Hello,

How do I wire a DMX cable that goes from 3pin XLR to Stereo Jack?

xlr is pin1 ground, 2+, 3-

jack is tip+, mid -, base ground, like with audio.
 
some units are sometimes wired differently, but that will be specified in the manual. i just gave you standard wiring.

Pat, please start checking your facts before posting.

For DMX the convention is 1: Ground, 2: Cold 3: Hot.  ie pins 2 and three are reversed with respect to audio.

For the jack connection (is it an NJD unit by any chance?) it depends on the individual unit because using a jack connection is non-standard.  Try an ordinary audio XLR -> balanced jack convertor.  If it doesn't work add a phase reverse (swap pins 2 and 3) and try that.  You won't hurt anything by having pins 2 and 3 reversed, it most likely just won't work at all or behave oddly.

+1

If it's for a NJD Datamoon it is wired Tip hot, ring cold, sheild ground (I doubt NJD swapped their system for any other products but you never know...).

PS are you sure its a dmx input? 1/4" jacks get used for all sorts in the world of lighting (dc output, strobe trigger pulses etc) be a bit carefull if its a bit unknown.

It's an Abstract Futurescan II/III Controller which goes XLR to Jack to the first Futurescan II DMX 150 and then stereo jacks between all the heads.



I'm guessing the stereo jacks are for DMX.

Well the TRS Jacks won't matter but the XLR to TRS might.
