Fred,
You do not need a separate serial cable, but you must plug the serial
adapter into the KPA500 instead of the K3/P3 combination to download
firmware to the KPA500.
Connect your serial cable directly to the KPA500 and then do the update,
then connect the cable back on the P3 and do the K3 update. If you have
the KAT500, connect its serial cable to the computer and do its firmware
update. When all have been updated, all should be well.

I've never connected a serial cable to the KPA500, I built it and used
whatever Elecraft had loaded. I'd like to update the FW now. The
current cabling is:
PC --> PigKnob gizmo --> P3 --> K3 and it all works fine. The KAT500
serial connection is a separate adapter ... a little annoying but I
can live with it.
Can I do:
PC --> PigKnob gizmo --> P3 --> KPA500 --> K3 or do I need a separate
USB adapter for the KPA500?
I'd just go try it out except the backside of my radio isn't real
accessible and gives totally new meaning to the term "wireless" so I
thought I'd ask first.
