[Elecraft] Interfacing K2 to KPA1500?

[Don Wilhelm]

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.

73,
Don W3FPR
