4.2 VT100 Terminal Screens
The 2461 modem uses a VT100 compatible Command/Modem port for connection to a terminal
or modem.
The rack modem requires an RJ-48C connection and the port is a DCE requiring a DTE
connection.
The stand alone requires a DE-9 connection. This port can be set up as DCE or DTE by
positioning the slide switch on the front panel to the right position. Selecting the TRM option will
configure the port as a DCE and selecting MDM will configure the port as a DTE.
The following tables provide connector pin assignments for both the RJ-48C and the DE-9 ports.
The I/O assignments for the 8-pin modular, RJ-48C style (DCE only) on the rack mount version
are:
