Updated them about 2 years ago when I first tried DMX. What's so weird about it is I can do 100% on and fade down to nothing with LOR protocol, but the LOR boards running on DMX don't get anything like the LOR protocol fades.
Also the megatree, I like to do spins and really get the lights spinning across it, but DMX across the LOR boards barely spins if the one board will even pick up the DMX.
As far as the models, the oldest is the heavy-duty residential model with the big heatsink and it can run it's own program--it was the first one I bought. It's a PC-CTB16PC but not a Gen-3, probably first gen. my other 4 LOR boards are the CTB16KS. If LOR made an E1.31 dongle so I could get away from USB, I'd probably buy it
