[Elecraft] How is the P3 Connected to the K3?

[Eric Swartz - WA6HHQ, Elecraft]

The P3 connects to theK3 via two cables that are supplied with the P3. A 
BNC RF cable that connects to the IF Out on the KXV3 (or KXV3a), and a 
RS-232 cable that connects to the K3's RS-232 control port. The P3 has 
another RS-232 connector that then optionally goes to your PC via a 
direct connection or the KUSB cable.

A PC is not required as part of the P3's regular operation, except for 
downloading new P3, or K3, firmware.

All P3-K3 communication is hidden from the remote PC. All PC control / 
logging commands to the K3, and K3 responses to those commands, pass 
through unimpeded via the P3.

Basically the P3/K3 combination is transparent with no changes needed to 
your external PC control and logging programs. The pair looks identical 
to the stand-alone K3 from a PC interface standpoint.
