[Elecraft] [K2] DE9 versus DB9, and how I can make a replacement cable

[Don Wilhelm]

  John,

I believe you have the KAT100-2, so you plug the KPA100 ribbon cable 
into the KAT100.  That makes the connection for all signals that appear 
on the external cable.  You only need one cable from the KIO2 - and it 
plugs into either the AUX I/O on the KAT100 or the KPA100, no need for 
both.  You should not have to construct anything other than what you 
already have.

Externally, the only connection between the KPA100 and the KAT100 is a 
short piece of coax and there should never be a need to remove it.

Technically, the 9 pin D-sub connector is the DE-9, but is often 
mis-named as a DB-9.

73,
Don W3FPR
