[Elecraft] KPA500 Remote

[Dana Roode]

Folks - who out there has set up their KPA500 as a part of a remote
station?  I'm planning to do so here, and wondering whether others
have used the pins in the AUX cable or plan to use software commands
to turn the Amp on and off, etc.  It appears both may be options.
There also appears to be a pin in the Aux cable that indicates a fault
condition, which would be handy to monitor remotely (I have a
LP-Remote board from N8LP).

I need to make a custom cable between the K3 and the KPA500 to connect
some lines (band indication, auxbus?) and bring out others - the ON
pin for the K3 that I currently use, the toggle ON/OFF pin for the
KPA500, etc.

So, what are others doing?  I see there are options to connect the KPA
to the K3 via RS232 not sure what that would buy me.
