[Elecraft] Hooking up k3,p3 and kpa500?

[Anndel]

Correction, the diagram is on Page 13 of the P3 manual.  The K3 connects to
the P3 with the RS232 connection (XCVR) and the computer connects to the PC
port on the P3.

You don't connect the K3, P3 and KPA500 with serial ports.

The P3 connects to the K3's serial port.  Your computer connects to the K3.
This shown on Page 3 of the P3 Owner's manual.

The K3 can connect to the KPA500  in  a couple of ways. You'll need a PL-259
jumper for the RF connection.  For the amplifier key line you can use a
cable with an RCA connector on each end, as shown on page 20 of the KPA500
owner's manual.  

Or you can use a 15-pin ACC cable from the K3's ACC connector to the
KPA500's ACC connector.  This provides additional functionality; the
amplifier can follow K3 band changes without transmitting, the K3 can follow
amplifier band switch select, and the K3 can change its output power
depending on whether the amplifier is in "operate" mode.   This is shown on
page 21 of the KPA500 owner's manual.

The KPA Utility uses a serial port connection to the KPA500 for firmware
installation, configuration save/restore, and remote operation, but it's a
different serial port connection than you'd use for the K3 / P3.

I have looked through the manuals and have not seen how one hooks up all
three together using the serial ports.  How is this done?
Thanks, Tom
