A–6 DECserver 90M Owner’s Manual
The BN24H is a twisted-pair (three twisted pairs) cable with a standard 8-pin
modular plug on one end and a 6-pin modified modular plug on the other end.
Use this cable to connect the DECserver 90M to an MMJ connector on an
asynchronous device. You also use the BN24H when connecting an asynchronous
device to a DECconnect wall plate.
Use an H8584-AA adapter when connecting the DECserver 90M to existing
MMJ wiring. The adapter uses a standard 8-pin modular plug on one side and a
6-pin modified modified plug on the other end.
Figure A–3 shows the wiring configuration for the BN24H cable and H8584-AA
adapter.
