Yep thanks guys .. I put it to 3 just 'cuz I saw 3 connectors and couldn't see how you could have 4 dmx but like I said, I don't use them anyways so it didn't really matter to me. I did look at the docs .. it shows as you noted a pic with just 1-2 and 3 labelled.
Anyways, this will come in real handy as I try and figure all this stuff out in a relatively short amount of time :-)
