Hello,

I just completed KRC2, initial test in page 15 of manual was successful.
Now completed final assembly and connect to K3 using AuxBus, turn
on 12V, LED does not turn on, K3 does not recognise KRC2.
Later I realised I should connect GND on pin 5 of K3 side, instead of
pin 6, which "KCR2" Manual Errata Rev C-2 Feb 11, 2009 instructed
me to do so.
Is there any possibility I damaged KRC2 because of this error?
After disconnect all cable and put 12V, still no LED light and no output.
