Well, I can dream fairly big. But that answers it completely for me. Mainly, with the amount of splits I'm intended, there's no issue. No way I would use more than just simple splits to do this task. I might take a split and adapt it to a modem cable for "out of band" monitoring and analysis to a laptop. 230Kbps isn't a whole lot for even a slow laptop to handle these days.
Off to make more DMX terminators from spare XLR plugs and save up for splitters.
Big show coming up(maybe, don't ask, story is a novel at this point). I'm finally getting around to learning to program my DMX Operator that I purchased back in 2002. As old as it may be, it works just fine. I am happy to be finally utlizing it. I also have to call up ADJ and order some parts.
Nice to see some protocols are very robust despite not having error correction.
