KPA500 + PR6 6 Meter Problem

[WD6DBM]

Dear Gang:
 
KPA500 274 is on the air.  However, with DIGOUT1 set to ON on 6m, the KPA500 will not amplify.  Ther OPER light is on, but the amp is in standby.  When I configure DIGOUT1 to OFF on 6m, then the KPA500 transmits, but the PR6 won't come on.
 
I am using a K3 with the ACC port daisy chained to XV144, XV432, and Top Ten Band Decoder as well as the KPA500.  The transverters and band decoder all seem to be functioning properly.  KPA500 transmits on all other bands.  Am I missing something, or is this a bug/feature?
