Anyone have success with this model controlling 232? All commands work fine when the projector is in the "ON" state, as soon as I issue the "Off" command the projector turns off and will not recognize the "ON" command. Projector returns "F" (fail).. Any tips?

I am sitting here with mine, having the exact same problem. Tech Support says there are no problems reported..

OK, I got mine to work. Tech support was totally useless, kept talking about the baud rate, meanwhile I was getting commands going back and forth.

I am controlling with a crestron processor, and the solution was to put the serial pacing to 1ms. The part of the projector you are talking to when it is OFF, is different than when it is ON and requires a slower rate.

Good luck.
