Thanks Craig. That was what I had expected. I encountered some=20
strange wording.=20

Merrick,=20

For all intent and purposes DC, VRef, Vcontrol, etc...are all ground.  =
Think
about the frequency you are dealing with and the affect on impedance.
Reactance is not an issue at DC since the Real parts of the impedance =
are >>
than the reactive parts.  The reactive parts are frequency dependant, =
and
the frequency of DC, etc... is zero for all intent and purposes.

One issue that may arise is ground bounce.  Since you are going to have =
one
voltage on the ground plane on one side of the connector and possibly a
different voltage on the ground plane on the side that is holding the =
other
half of the connector there will be a difference in the ground plane
voltages.  This is going to be pretty small, and is neglected quite =
often.

What issues could arrise by using a return path for DC voltage, =
Reference
voltage, or on-off control voltage? Would low AC impedance path be
interupted or changed in any manner?=20
