Installing/Configuring ad2usb

I am getting a new alarm panel next week (vista 21ip). I already have the ad2usb adapter. So I am wondering what I need to do in terms of setup while the technician is here. I read something about an installer code. Is that something I get from them, or have them do while here, or something I figure out after they leave?

I just don’t want to have them leave only to find out I need to have them come back.

Hopefully they will give you the installers code, if not have them activate a keypad in the panel at whatever address you setup your ad2usb as, default I think is 18. first keypad is always 16, then 17 and so on. also get a list of the other keypad addresses as you will need those when setting up the plugin.

OK, this makes sense, especially sorting through all the other info online too.

Much appreciated…
