Question:

I am attempting a very similar scenario. . .
Using a Xantech IRS232A to control a Proxima C460 via RS232.

The room is controlled with a Marantz 9500 & RX-77 RF Extender.

1st problem, the projector does not respond to the Xantech at all. ( I have confirmed that the correct ASCII strings are being sent & have tried the "test" feature in the Dragon Drop software)

2nd problem, the RX-77 does not seem to be talking to the IRS232A.
The RX-77 is receiving the signal from the remote (LED lights indicate this), but then there is no response from the IRS232A (LED's show no activity)

Any ideas and/or suggestions would be greatly appreciated.

Thanks!!!
