no I am not sure at all!
so the short answer to my question would be is when you get a Crestron system, it cannot properly control everything, but you should choose the devices based on their RS232 capabilities?
If so it's helping me set my expectations at the right level!
I thought there was a way to do this with any device (I read something about Logitech having some way of receiving IR feedback in Harmony 1100, but not sure it actually works)...

thanks
