To configure the system, connect a serial cable to a COM port on a PC or
notebook computer and to RJ-45 type serial (console) port of the Managed
Industrial Switch. The console port of the Managed Industrial Switch is
DCE already, so that you can connect the console port directly through PC
without the need of Null Modem.
A terminal program is required to make the software connection to the IFS
Managed Industrial Switch. Windows' Hyper Terminal program may be a
good choice. The Hyper Terminal can be accessed from the Start menu.
