2.2 CONFIGURING THE TERMINAL CABLE
Local management can be accessed by direct connection to a management
terminal by using the RS232 cable and one of the three conversion
connectors shipped with the TRMM/TRMMIM. Two converters are
labeled according to the type of terminal (VT Series and PC) they can be
used with. The converter labeled Modem is used for module-to-modem
connections.
The VT Series connector converts the RJ-45 connector on the cable to a
25-pin female connector, the PC connector converts the RJ-45 connector
to a 9-pin female connector, and the Modem connector converts the RJ-45
connector to a 25-pin male connector.
