Tom,
Do NOT connect a standard serial cable or a USB to RS-232 adapter to the
K2 (KIO2) AUX IO connector. Note that it is labeled AUX IO and NOT
RS-232. It contains internal K2 signals for external Elecraft gear such
as the KAT100, KRC2 or the XV series transverters.
Build the special K2 to PC cable if you have not done so already, and
connect it to an RS-232 port on the computer. If you do not have RS-232
ports, then you will need a USB to RS-232 adapter. Those with an FTDI
chipset such as the Elecraft KUSB work best. Those with a prolific
chipset are problematic.

The manual for the KIO2 says you can use a 24 pin to 9 pin adapter, but it
does not mention connecting to USB. Since the cable is so specialized for
the KIO2 to K2 can I connect it with the 9pin to USB prolific cable? I
don't want to short anything out etc...
Thanks and 73,
