[Elecraft] K2 - KIO2 Question

[Don Wilhelm]

Sorry,

I gave mis-information because of my cursory view of the question.

For the K2, you must use the special cable that is shown in the KIO2 
manual.  That cable must connect RXD and TXD and *no* other RS-232 
signals to the KIO2 connector.

Once you have constructed the KIO2 cable, you can connect a standard 
serial cable to the "computer end" - there are no wires for other than 
the TXD and RXD signals, so no danger.

Bottom line, do not connect any USB to serial adapter directly to the 
KIO2 or the KPA100 -- the special cable must be used at the KIO2 end.
