 AFAIK, the connectors for a DLV11-J are 2x7-way... There are only nine

  pins (one is missing for keying), but the extra bits

 the connector.  2x5 will work, if you don't miss. 
No, the DEC spec says 2x5.  The connectors are AMP connectors; the ones
on the DLV11-J itself are 87272-8 and the ones on a BC21B cable (for
example) are 87133-5.  You can fit a Bergcon 2x7 if you push hard, but
it distorts the shroud slightly.  All the cables I've ever seen,
including original DEC, are 2x5 housings.  If the key is in place, you
can't really miss.

 No kidding.  One other "problem" is that you need to stock one set of
 pins for small connectors (like the DLV11-J) and another set of pins
 for large connectors (like an RL8A - 40 pins) because there are different

pins, but they were spec'ed

  different for a reason.  "Weak" pins in a
small connector might not
 grab enough to stay in well enough, and "strong" pins in a large
connector

  might be too difficult to insert. 
Well, that's not "weak" and "strong" by design, it's for
different
sizes of square pins, or for round pins.  Yes, I agree, don't use the
wrong ones!
