I need some more info on this feature. Is this a wireless sync? Otherwise what's the difference from running a master/slave link?

This is defintely NOT a wireless thing, that is for sure.

I think this is more of an "updated" version of master/slave that can work with like-type fixtures. For example, the 64 LED Pro and LED Punch pro are basically variants of the samething. I would think that this would mean that they can master/slave off each other. So, I think this is a variation on "identical fixture master/slave" issues.

Also, this would NOT work over wireless because the wireless DMX units are only for transmitting DMX, not any other protocol.
