OPEN CKT after thunderstorm

Hi, I'm having problems with my AD2USB. After an year of working perfectly my unit beginning to be the cause of an OPEN CKT in my Vista 20P. A huge thunderstorm passed over my house and fried many thing including my Vista panel. After purchasing another one, re program it and test it that everything is working fine, I connect my AD2USB and the error shows up in my keyboard (6162RF). The AD2USB responds correctly when is connected to my computer thru the GUI or Putty but never receive a message from the panel. I like to know if is anything that I can do to test the unit or I need to send it to you guys to repair or buy another one? Thank you very much for your help.
PD: GREAT PRODUCT!!!!
