I tried it for the hell of it... A couple of the lights flash around when you plug it into the mac running the cat software, and it comes up as CIB ok, but when I hit DMX into it, nothing happens. No lights turn on, and in the HUD no channels change from a 0 level.

It looks like some of the architecture is in place for it to work again.. Would it be possible to get it back up and running?

It has a light for RX mode which normally doesn't work in normal output, so it seems it would be possible..
