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.

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!
