So, bit long winded but.... 5 LED uplighters on stage, DMX controlled, working fine for over a year suddenly started behaving erratically, random flashes. also caused PARs on dimmer pack to blow due to this random strobing.Individually tested each LED, swapped DMX cables and found that someone had rolled our 1 ton piano over the DMX cable that runs across rear of stage, replaced cable, re-plumbed everything, replaced blown PARs.All working as it should.Now, after repairing damaged cable that was shorting out, cut beyond damage and resoldered XLR, discovered that the XLR plugs on each end were connected differently, ie.. male pin 1 to female pin 1, male pin 2 to female common, male common to female pin 2. I know that in an audio cable this could be an issue, but it seems not to be an issue in the DMX cable. Is this the case?
