Raspberry Pi

(Redirected from AD2PI)

There are several ways to start using your AlarmDecoder with the Raspberry Pi. While you can use all of the AlarmDecoder products with the Raspberry Pi, the AD2PI was specifically designed to interface with it directly. If you're attempting to connect an AD2USB or an AD2SERIAL please follow the standard Linux instructions here.

There are a couple of steps involved with getting your AD2PI and Raspberry Pi talking to each other. We've done all the initial footwork and highly recommend downloading the modified Raspbian image below and flashing it as described here. If you intend to go with another distribution, or just want to do it yourself, then follow the instructions here to start using your device.
