GE Simon XT GSM module interface pinout and protocol


I have a Simon GE XT without monitoring service. I am interested in finding out the pinout of the GSM module interface connector and the protocol used to communicate between GSM modiule and Simon XT controller. I am a hardware/software engineer and I want to design a hardware which plugs into the GSM module connection and provides a way to control the device remotely over the internet. Can anybody provide some data?

Security hardware manufacturers aren't too forthcoming with the hardware and firmware level technical details on their products. You might find that kind of info available on something like a home automation forum or an electronics mod site.

All that folks like us can get is what the Tech Support makes available, plus experience.

Maybe some chip-modder has ferreted out this info...
