Command Line Interface
The network extender can be managed with a Command Line Interface (CLI) through
either a direct PC to COM (Communication) Port connection or from a remote network
connection via Telnet.
CLI System Requirements
Straight-Through 8-Pin Modular Ethernet Cable – Required for establishing a
direct connection from the COM port to a DB9 adapter.
DB9 Female to 8-Pin Modular Male Adapter – Required for conversion of your
PC's RS232 serial port for use with the Ethernet cable.
Terminal Emulation Program – Required for running the CLI over a direct
connection. The program must emulate a VT100 terminal.
Telnet Client – Required for remote management with the CLI. Microsoft Windows
Operating Systems (98, 2000, NT, and XP) include a Telnet client which is run
using the Windows command prompt (cmd.exe). If you are using an operating
system other than Windows, you may need to install a Telnet client.
Connecting a PC Directly
Initial configuration using the CLI requires a direct physical connection from your PC to
the COM port of the network extender you are configuring. (However, the web interface
is recommended for subsequent configuration.)
Procedure
1. Plug a DB9 to 8-pin modular adapter into the RS232 serial port on your PC. See
DB9 to 8-Pin Modular Adapter Pin Assignments on page 21.
2. Connect one end of a straight-through Ethernet cable into the adapter plugged into
your PC, and the other end of the cable into the COM port on the face of the
network extender.
Launching the Terminal Emulation Program
Launch the terminal emulation program on your PC and configure the program
settings. Actual configurations will depend upon the program being used, though
settings should be modeled after the list below; most are standard defaults. Refer to
your terminal emulation program's user manual for further information.
