[Elecraft] KXPA100 RS-232 problem

[Thomas Beltran]

Hi Dick John and Don and thank you.  I checked everything and it was good.
I realized the KXPA100 did not have the current firmware, so I attempted to
upgrade it.  The upgrade failed, and now the utility cannot even connect to
the  KXPA100.  I tried a different computer and same result.  For now, I
just unhooked the KXPA100, and I am able to drive my SG-500 to about 200
watts with the KX3 alone.  I will have to revisit the amp problem.  However,
right now, I just received the loop and wanted to make sure it works.  Thank
you for your reponses.  Later, I will try to communicate with the KXPA100
alone and see what I can find out.  Thank you.

Tom,

Do you have the KX3 to KXPA100 adapter cable plugged as indicated on page 14
of the KXPA100 manual?  If so, make certain the RJ-45 plugs are fully
inserted - you should hear a slight click when they are fully mated.  If
there is any doubt about them seating, pull back the boot on the RJ-45 cable
end and push the inside connector body "home".
