It was a brain storm on my part. I wasn't even thinking about taking 12v from a hub.
I was thinking there are 16K channels coming out of an etherdongle so just for the sake of argument lets say I have two hubs and am using 3900 channels for pixelnet on each hub. That leaves me with 384 channels that I can pull from the hubs as DMX.
I have many more channels than that available but to get any more than that I need to add another hub, which as I mentioned is a bulky item (as it should be).
My thought was that all the components that are needed to get those extra DMX channels are a small subset of a full blown hub so why not have that smaller device?
Thats all I was thinking about. Just my idle mind trying to fill in gaps.
Again just my brainstorm...
(the above example is how I ran my show last year. I had an extra dongle so the extra DMX was easy to come by. but with the ehterdongle and conductor solution I could see wanting to get more DMX out and not having away to do it short of adding another hub...)
