If anyone can please lend their wealth of knowledge and help us to find the RS232 codes for the Russound CAS44 unit.

I have a client who has a Global Cache GC-100-12 and has purchased himself a Russound CAS44 for multiroom audio. They would like us to set up their Demopad interface (they use and iPad) and use the serial port on the GC for control, sounds easy I thought, just search Russound.com or internet for codes and I will be away laughing.........Wow that didn't happen, I can find many IR codes for single zone but not for the 4 individual zones, an RS232.ccf file that is only IR codes and does not give what they are for, pretty much my last resort is to ask for help.

HELP :)

A huge thank you in advance and even one for taking the time to read this request ;)
