[Elecraft] KRC2 + K2 + XV + PC = cabling confusion

[Jack Brindle]

John;

As I recall your configuration, your KRC2 uses the band info from the  
Auxbus to select the various transverters. I don't believe that it  
needs the RS-232 communications for your use. This means that  you  
can fabricate a cable that connects the K2's serial port to the  
computer. The KRC2 and the XVT both need most of the remaining  
signals, so you can connect them from the K2 to the KRC2 and the XVT  
in any convenient fashion. The easiest would be to cable from the K2  
to the KRC2, then from the second KRC2 connector to the XVT. You  
might want to look at the cable fabricated  for the KAT100, it  
provides the connections you need, so something very similar might be  
the way for you to go.

Good luck with it, let me know if you need help.
