There is also DD, though I've never seen one in the wild. DA is the shell for
AUI connectors, DC is used for RS-422 (37 pins) I think.
All of these come in regular density and high density variations. For most of
them, regular is 2 rows and HD is 3 -- so a VGA connector is a DE-15, high
density DE shell connector. But the DD regular density is 3 rows and the high
density is 4 rows.
Meanwhile, on AUI cables: the difficulty with plugging a transceiver into the
Pro is that the Pro uses regular nuts, for a plug that secures by screws.
That's non-standard, since the AUI spec calls for the "turret" and sliding
latch type. So a standard AUI cable wouldn't be a real cure because you'd
still have that mismatch.
A simple solution is an adapter. I bought one from L-com:
https://www.l-com.com/d-sub-aui-to-db15-adapter-male-female which says that it
is "discontinued" but also shows "available: 11" so perhaps you can still get
one. Failing that, an option would be to get a "socket saver" -- which is just
a thin device with a connector at each end, intended to save the device
connectors from wear -- and remove the transceiver-side fastener so the
transceiver can plug in. That second option doesn't give you a secure
attachment but it's likely good enough.
