Its better to keep signal ground and screen separate... so generally
I use a core in a screened cable for signal ground, and save the
screen for its intended purpose.

I take it that one end of the cable has a flying braided lead to earth
the screen then?

On the 25 way connector pin 1 is reserved for screen, and pin 7 for
signal ground. The screen is also in theory paralleled with the shell of
the D connector.

Thanks John, I don't have my spec handy at the moment and it has been a
long time since I played with these conectors.
