Please carefully check the configurations in HRD, DM780 and the K3. 
Assume they all changed to something you didn't want, and verify they 
are all exactly as you really want them.

There have been changes in the K3 firmware, changes in HRD, and changes 
in DM780 in the past few months.  Occasionally, upgrading the K3 
firmware has apparently resulted in unexpected configuration changes in 
some isolated cases.

Rather than go back to older firmware, just scroll through all the 
OCNFIG settings and be sure they are what you want, and that they do 
what you expect.

The K3, HRD and DM780 will all work well together.
