So the venue that I just started working at has alot of unused equipment that I will be ressurecting. Namely older martin gear: 2 roboscan 518s, 2 roboscan 812s, 5 acrobats, and a 1200w centrepiece. It's all controlled by an MLC16, which already has everything patched in. Currently, all of the lights are over the dance floor. I plan to move the 812s and 518s to the stage. To do this, I will run a DMX run either down the snake or along the ceiling from the dance floor lighting DMX points. Now to my question: what is the difference between 3-pin DMX and the Martin protocol that is used for the 518s and the 812s? I've heard from some that it's just pin 2 and 3 swapped, but I haven't done enough research to confirm this. I'd like to make some adapters that I can put on the backs of the fixtures that turn DMX in to martin protocol and then martin protocol back in to DMX to hook to, say, one of the Colorsplash Jrs that I'll be getting soon. Could I simply do this by making adapters that are simply pin 2 and 3 crossover cables?
