[Elecraft] KPA100 & KAT100 integration - Question answered!

[bobconvers at aol.com]

DOH! -  It all seems so obvious now - for one thing, I could not use my 
existing control cable (without the KIO2) because the barefoot K2 has 
no place to plug it in!

I now understand that:

(1) the KIO2 includes a new DB9 connector for the barefoot K2 rear 
panel, and

(2) that one of the functions of the KIO2 (in addition to level 
shifting, etc, for computer control) is provide an internal 
interconnnection for the AUXBUS and other control signals from Control 
Board ribbon cable connector of the barefoot K2  to the new DB9 
connector, from which the signals can be conveyed (via control cable) 
to the KPA100/KAT100 in the new box.

Many thanks to those who replied to my question.
