K2/100 - "Info 080" message

[Tom]

   On the heels of my XV432 'issue', and totally unrelated because the XV432 is
interfaced to a FlexRadio, my faithful K2/100 is showing an "Info 080" message on startup.
I've found that by unplugging the DB9 from my KAT100 the rig operates normally.  

  What is my next step to track down the problem ?


   All suggestions welcome ;0)

Tom,

An INFO 080 message is the result of a failure of the MCU to obtain the
expected response from another microprocessor in the expected time.

Since it does not happen when you disconnect the KAT100, I would suggest
first checking the connecting cable, then the AUXBUS path in the
KAT100.  Try reseating the KAT100 firmware IC if you do not find a cable
problem, and if all else fails, replace the KAT100 firmware.

Hi Tom / Don,

I had a similar intermittent problem, when dissasembling and
re-assembling my K2 /100 #6936 during installation of the XV-60 module.
All my efforts attempting to debug the problem were unsuccessful, and in
the end I suspected that I had killed U1 (or some other PIC) by mistake.

Then - the INFO-080 error surprisingly went away again; as I found that
the problem dissapeared after properly unplugging and re- securing the
data bus cable (flat ribbon cable) between the K2 and the KPA 100 again.

Away went the problem and I haven't seen it since ... Only the next day
after the fix,  the rig took a pounding 48-hour CQWW CQ operation,
flawlessly.
