Andy and all,
Perhaps the confusion is coming from the similarity of names.
The "AUXBUS" is a proprietary single wire communicaions interface that
is used for communications between various units in the Elecraft gear -
if for no other reason than to test for the presence of a particular
It's clear that both the KPA500 and KAT500 must be RS-232 transmitters as well
as RS-232 receivers. If that were not true then the PC utilities could not
function. My station data logger has been polling, and receiving responses
from, my KPA500 since I first built it.
Now I know that the
That make no sense to me.

Now I'm getting confused. Based on earlier
Hi Andy,

This means that they can both read the status information from a Kenwood's
COM port and act on it.
This does not require the AUX cables

My KPA500 receives serial data (listen only) from my TS-590 and follows TS-590
band changes without needing RF input. If I connect the KPA500 and KAT500
with an AUX cable will the KAT500 be selected to the same band as the KPA500
before receiving RF input? If so, what minimum pin connection
