I expected to see the SBE capture cards defined in the MBE system in the
status page or in the setup on the MBE.

On each system (SBE and MBE) I just see the cards in those systems
defined.

That is what I don't see.  Have verified that the SBE can connect to the
MBE.

I see one entry for the SBE.

None taken.  I figure it is something simple that I have missed.  A step
in the documentation that I skipped or a permission somewhere that is
not right.

Another question I have:  Do I even need to have mysql running on the
SBE?

Yeah, I'm trying to add some additional encoders to the mix.
