The keypads were built by URC, and the editor is their software. Alot of guys, myself included, use IOGear's USB to Serial adaptor with great success. I have a few CT600.1 and 3s out there, and have no trouble updating them. However, I'm running Vista on my laptop.

Just a quick update and my Thanks!
I received an IOGEAR GUC232A USB to Serial RS232 Adapter that was recommended and it works great on my Windows 7 based system. I purchased it from Amazon.com.
Thanks Again,
Gary
