The cable on Eric's site is USB to RS-232. This is definitely NOT the cable to use unless you have one of the HP RS-232 programming adapter cables.

As Mark pointed out, a cable that brings out 3.3V power is desirable if you want to incorporate the RESET and PROGRAM switches like on Harald's board in Katie's article.

Once you have the cable electronics figured out you can fashion a plug.

I added a second connector housing to help prevent the pogo pins from getting bent.



Good luck!
