[Elecraft] K2 - KIO2 Question

[stan levandowski]

I have a K2/10.  I also have a K3/10.  If I purchase the KIO2 option for 
the K2 can I use the same USB-Serial adapter cable I'm using with the K3 
or do I have to buy the "KUSB" product listed right below it on the 
Elecraft Order page.

Thanks and 73,
