The BN24H is a twisted-pair (three twisted pairs) cable with a standard 8-pin RJ45 connector on one end
and a 6-pin modified modular plug on the other end. Use this cable to connect the DECserver ConX
an MMJ connector on an asynchronous device. You can also use the BN24H when connecting an
asynchronous device to a DECconnect wall plate.
Use an H8584-AA adapter when connecting the DECserver ConX
uses a standard 8-pin RJ45 connector on one side and a 6-pin modified plug on the other end.
Figure A-3 shows the wiring configuration for the BN24H cable and H8584-AA adapter.
