AD2USB without alarm panel

[tangoVictor]

Probably a noob question, but I want to use a AD2USB device to connect a couple of 6160 keypads to a Linux USB port. Is this possible?

I want to send status messages to the keypad display and get key presses back. I saw mention of possibly supporting this on the nutech forums from 7 years ago. Not sure if this capability exists in the current product. This would potentially save me a lot of time reverse engineering the keybus protocol.

Here is a link to the old thread I mentioned above: http://archive.nutech.com/index.php?opt ... d=4&id=557

Currently using the alarmdecoder without an alarm panel would not be possible

Dang. Thanks for the quick answer. Is it just something you guys did not have enough customer interest in? Or is there some technical reason it would not work? Just wondering before I start trying to figure out the protocol for myself....

The approach we would have taken (becoming the alarm panel) was far outside a gray area we were willing to deal with

If anyone else is interested in talking directly to a keypad (without an alarm panel), I was able to connect an Arduino to my keypad successfully. I have posted a repository on github with my code and what I learned about the interace here: https://github.com/TomVickers/Arduino2keypad
