  • Designed to connect an Ademco/Honeywell Vista 10se, 20se, 15p, 20p, 21ip, 50p other Vista security system to a HomeSeer PC, Mi Casa Verde Vera and other Home Automation Controllers
  • Operate alarm system remotely with virtual keypad

Essential Info

This PC interface board is designed to allow control of your Ademco/Honeywell Vista alarm systems from a computer running Windows, Linux, or OSX. The AD2USB presents itself to your computer as a virtual serial port and only consumes 20-30mA. Just attach the AD2USB to the four wires from the alarm panel or extend the existing alarm panel keypad wires to the device.

Once connected, you will be able to arm/disarm the system, detect and monitor opening and closing of zones, unlock or discover installer codes, program your panel, download programming, set triggers for virtual zones, and even monitor your alarm sensors directly from your home automation system. You can even backup your alarm configurations to a file. A full ALPHA keypad emulator is included, so you won’t need a physical keypad to program the alarm. The AD2USB comes with firmware and a bootloader so you can upload new firmware as improvements are added.

NOTE: The AD2USB requires a USB A to Mini USB B cable (not included).

even if it doesn't work at first the tech support is excellent and will have you up asap and they're very polite as well. 5/5 would buy again.
ROBERT S. -- tucson, AZ   6/24/2014
There is good support to get the novice user going with the basic functions. The advanced functions will require some knowledge or willingness to learn, but there is support for those functions too. The price seems somewhat high, but it's the only device I could find that does what it does.
ROXY -- columbia, SC   5/19/2014
NuTech adapter was received on time. No service was required. The installation with Honeywell unit is not complete yet so we can not check final operation at this time.
NATALIA -- delray beach, FL   5/3/2014
Quick service excellent
BRADLEY -- westville, NS   2/26/2014
Great product but even better service.
JEREMY -- salt lake city, UT   12/14/2013
I bought this to connect a Vista 21-iP to a MiCasaVerde VeraLite, and it appears to work perfectly. The price seems a bit dear for what should be a simple serial device, but that's often the case with security system components. In the end, the automation that it enables will be worth it.
GARFIELD WAYNE -- alpharetta, GA   12/9/2013
Great device, wonderful support from the manufacturer, however is took a bit of time to get to me.
PATRICK -- annapolis, MD   11/28/2013
Its small, simple, and it works.
SCOTT -- suwanee, GA   11/25/2013
Works great with my security system and my raspberry pi!
DANIEL -- wilmore, KY   11/21/2013
Love how easy this is to interface with my panel and Homeseer. Works great.
ROB -- valencia, CA   10/9/2013
I have an old Ademco Vista 10SE. This genius product unlocks every last bit of capability out of it. It can either report on, or simulate the presence of many Ademco accessories.
RALPH -- dundas, ON   12/8/2012
Performs exactly like advertised. My installation problems resulted from a self supplied defective mini-USB cable. NuTech was very approachable and helpful in sorting out the problem.
ROBIN -- round rock, TX   11/25/2012
Great product! I have the AD2USB and a Raspberry Pi computer set up to monitor my Ademco security system and send me a text message if an alarm is triggered.
JAMES -- san antonio, TX   7/28/2012
I have been using the AD2USB
DAX -- san antonio, TX   6/30/2012
Had to add and remove the device twice in MiCasaVerde to make it work and it was a lot of reading of my alarm system manual before I was confident I had enabled my keypad correctly. But works great now that it's all setup!
COLIN -- woodbridge, XX   5/26/2012
very useful device and simple to use
RICHARD A. -- poinciana, FL   3/8/2012
You have to be a programming get this thing working. Directions for use with MAC are unclear and hard to follow.
alarm_dude -- Oregon   2/23/2012
Wonderful device. Integrates with almost any Ademco Alarm Panel, and is supported by major industry players in the home automation realm. A must if you would like control of your alarm panel from your computer or other device.
PETER -- wellington, FL   1/13/2012
So far, so good! Easy to connect if you have any wiring skills. Received panel messages right away but you must ensure you have an available keypad device programmed into the panel. I have it connected to the HomeSeer Vista plug-in and has been working like a champ for a few weeks.
STEVEN D -- columbus, OH   5/27/2011
The AD2USB works well.
