[Elecraft] KIO2 RS-232 to USB?

[Don Wilhelm]

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.

73,
