Interfacing K2 to KPA1500?

[Elecraft mailing list]

The KPA1500 Manual mentions using a K2 with serial interface for band data, but does not show how to wire it (that I can find).  I can't find it in the nabble archive either.  Does anyone know how to do this?
Thanks and

73, Eric WD6DBM

Eric,

The KPA100 RS-232 data appears on pins 2 and 3 of the AUX IO connector
with pin 5 being RS-232 Signal Ground.  Chassis ground is on pin 1. See
the KPA100 manual.
DO NOT connect to any other pins of the AUX IO connector, those are
internal K2 signals to be used by external devices such as the KAT100 or
XV series transverters.

I can't help with the KPA1500 end.

Use the Kenwood diagram in the KPA manual.   Use the pinout in the K2 manual for the serial port and wire accordingly.  3 wires (TXD, RXD, GND) is all you need from the K2.  Then select SERIAL as the radio type in the KPA.  You may also need RADIO POLL to be turned on.

Don, et al,
Can I assume the same is true of a K2/10 with the AUX IO option?  Are they wired the same?

Eric,

Yes, they are wired the same - see the KIO2 manual.
