DMX Termination For Dummies.. Please Help! Hi Guys. I am really not getting this whole DMX termination deal. I have looked through a bunch of threads and it is not getting through my brain... Can you please give me a plain and simple (explain it to me like I'm a caveman), what does DMX termination do, and how do I do it? When people say "put a 120 ohm, 1/4 watt resistor across pins 2 & 3," what does that mean? Thanks!
