...If you have more information about the RFX9600 control protocol, feel free to PM me and I'll take a look.
Correct. My Pronto guru tells me Pronto probably talks to the serial extender by UDP packets. However the protocol is not in public release so we're snookered with this approach.
However, there is a solution available through CBUS (Clipsal's home automation system).
Remotescape can connect to CBUS via TCP/IP (either to a C-Gate server which supports multiple connections, or to a dedicated CNI which supports a single connection). CBUS has an infra-red output device which can store up to 200 discrete IR codes. So Remotescape connects to CBUS, tells CBUS which command to send, CBUS sends the command to the device, device reacts accordingly. Simple! With this approach the actual IR commands are stored in CBUS. Remotescape is just triggering a particular "CBUS event".
This can also be done similarly as a serial command in CBUS using a PCI.
If the serial port of the AV processor is already connected to a control system via RS232, which in my case the Halcro SSP is connected to the Pronto RFX9600, I can still control it with Remotescape through the CBUS/IR route. So I can control my volume both in the normal way with the Pronto, and with Remotescape.
This would make Remotescape a very powerful app because then it would be able to control lights, blinds, curtains, shutters, screens, HVAC, and anything else connected to CBUS.
The CBUS TCP/IP protocol is very well documented. I'll track down a copy and send it to you. If Remotescape could penetrate the CBUS market then you'd open up a huge customer base.
