My feeling is that any DC ground that I should make available on the
external connector should be taken from *before* the common mode
choke, since if it was the 'filtered' DC ground that was made
available externally, the filter itself would get shunted if
'external' grounds were commoned.
I suppose it depends
Ditto. The system as a whole must be considered.
