Connecting a VT100 Terminal
To connect a VT100 terminal directly to the MSH hub you need a
standard null modem cable. Connect one end of the cable to the
RS232 port on the MSH Display Panel, and the other to the RS232 port
on your VT100 terminal.

software. Many VT100 terminal emulation packages are available. Refer
to your software manuals for details. Consult your supplier if you need
advice.
If you are using a PC, you need a null modem cable with an
appropriate connector.
Whether you are using a terminal or an emulator, no further setup is
needed: the management system automatically adjusts its speed to the
baud rate of the terminal. You may need to alter locally some of the
terminal’s RS232 port parameters to suit your terminal. Refer to your
software manuals for details. To get access to the management
functions, simply ‘wake up’ the interface (see the note below), log on
