Tom,if you want 1 way RS232 control via the pronto, there is a product available. The remote reciever is around $100.00. If you are interested, please feel free to contact me. This, with programming, would probably be around the same price as the T-2.
Otherwise, this looks like a very useful remote and should be an easy sell. I just requested sales info on it for my store and can't wait to see one.
