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

[Dick Dievendorff]

There are three connections between the P3 and your K3. The necessary cables
are supplied.

1) A +12V cable connects between the P3 and the RCA +12V connector on the
back of the K3.
2) A short coaxial cable with BNC connectors connects to the IF OUT
connector on the KXV3 or KXV3A of your K3.
3) A short RS-232 cable connects between the P3 and the DB-9 RS-232
connector on the back of your K3.

Your PC or microHAM RS-232 connector plugs into the DB-9 connector on the
P3. The P3 passes computer-initiated commands and their responses to/from
your K3. The P3 also communicates with the K3 over this same serial
connection.  The PC/microHAM device sees the combination as a K3.

Note that a computer is *not* required to operate the P3, except for
firmware loading.

However if you wish to connect a computer to the K3/P3 combination, it goes
onto the back of the P3.

I'm curious how the P3 is connected to the K3.  Currently I have the RS-232
and the 15pin Accessory port connected to my Microham Microkeyer II.  Will
the P3 need the same connections? if so is there a way to get the P3 and
MicrokeyerII to coexist.
