Hallo,

Does anyone know conclusively if the KUSB USB to serial adapter
listed on the Electaft website will work with a K2 and Vista?

Regarding USB adapters: there are several variables, including the hardware and software of the computer, plus of course the adapter and its drivers, etc. So the answer has to be a resounding MAYBE.

As far as Vista is concerned, I don't know. I've used various USB to Serial adapters for my K2 with Windows 200 & Windows XP for years now and they have worked very well, and the KUSB is nothing more than an USB to Serial adapter, using afaik a widespread solution (chip) by Prolific <http://www.prolific.com.tw/eng/support.asp>.

That said, shortly before my K3 arrived, my old Sony laptop decided it was time to go to the big bit bucket in the sky. My new computer is an Apple MacBook Pro, which allows me to run MacOS and, with Boot Camp, I can also run Windows XP Professional as a "native" OS. The KUSB mostly works with the Boot Camp/Windows combination and my K3. Unfortunately only mostly, because the Win-Test logger is occasionally confused by the data coming from the adapter, and some versions of the K3 firmware loader were not able to switch the baud rate as needed. These issues almost certainly have to do with the USB/Serial drivers running on my slightly unusual combination of hard- and software. I'll be doing some more testing this weekend.

Bottom line: If the KUSB works correctly with Vista, it will work with your K2 and there is a very good chance that the KUSB will work well with Vista running on a "standard" hardware surrounding.


One thing for sure, be VERY careful to use a cable between the K2 and the adapter that only connects the RS232 signals and not the K2-specific lines that appear on the connector on the K2. See the K2 manual for details.

*** THIS IS IMPORTANT! DO NOT CONNECT THE KUSB DIRECTLY TO YOUR K2! ***

You will need an adapter from standard RS-232 (KUSB) pinning to the K2 pinning.
