Ground pins on the NI SHC68-H1X38 cable?

[BC23]

Does anyone know how the DIO signals are grounded at the high density card interface of the NI SHC68-H1X38 cable?  Which pins are the ground pins, and are they all tied together?

P.S.  I''m not sure if this is the correct location for this question.

No, this is a board for an obsolete product called Measure. You can ask the moderator to move it to the Digital I/O board.
