AD2PI and Vista20p - Please Help

Hi Guys,
I am in need of a little help and advice here if I may? I recently purchased the AD2PI module, and have added it to a PI and connected it to my Vista20p panel. I can communicate with the module over serial, both locally and using the ser2sock software.
Problem 1 - the device seems to 'lose' its address setting, is this normal?
When I first connected the device to my Pi and connected to the device, I noticed that the address reported was 00. I changed this to 18 however I notice that whenever I disconnect power to the module, for example powering down and powering up the alarm panel, the configuration is lost and the address reverts back to 00. Is this normal? Can I do anything to have this setting save.
Problem 2 - I don't seem to get any messages from the alarm, am I missing something?
I have checked and double-checked my wiring, and I can connect AD2PI device however I don't seem to get anything back from the alarm. If I use the keypad application (over ser2sock), I get the 'waiting first message' response.
I have enabled the 3rd keypad using *191 01 in installer mode using one of the other keypads which according to the manual (if I am reading it correctly) says that keypad has address 18. I have powered everything down and back up again after doing this however I still don't get anything.
Now I admit I am very new and may be missing something entirely.
Please can anyone offer any advice?
Many Thanks!
Jon
