As far as I can tell, the pinouts for the 20-pin BERG connectors on the DEQNA, DELQA, and DEUNA are functionally equivalent. (The DELQA uses 2 extra lines, but those will most likely be ignored, particularly if you're using a media converter, to translate to RJ45. . .) You can also use the DELQA / DEQNA cab-kits interchangeably, for basic ethernet operations on the PDP-11. . . As info. . . .
