Conﬁguring Telnet software

If you are conﬁguring your router using a Telnet session, your computer must be running a Telnet software program.

■If you connect a PC with Microsoft Windows, you can use a Windows Telnet application or simply run Telnet from the Start menu.

■If you connect a Macintosh computer, you can use the NCSA Telnet program supplied on the Netopia 4541/4542 CD. You install NCSA Telnet by simply dragging the application from the CD to your hard disk.

Connecting a console cable to your router

You can perform all of the system conﬁguration activities for your Netopia 4541/4542 through a local serial console connection using terminal emulation software, such as HyperTerminal provided with Windows 95, 98, 2000, or NT on the PC, or ZTerm, included on the Netopia CD, for Macintosh computers.

The Netopia 4541/4542 back panel has a connector labeled “Console” for attaching the Router to either a PC or Macintosh computer via the serial port on the computer. (On a Macintosh computer, the serial port is called the Modem port or Printer port.) This connection lets you use the computer to conﬁgure and monitor the Netopia 4541/4542 via the console screens.

Console connection port

DB-9 (male)

To connect the Netopia 4541/4542 to your computer for serial console communication, use a console cable appropriate to your platform:

■A DB-9 connector end attaches to a PC.

■A mini-DIN8 connector end attaches to a Macintosh computer depending on your computer’s serial bus type. Since Macintosh computers have different serial bus connectors, you will need a mini-DIN8-to-DB-9 adapter. These are available from a variety of third-party manufacturers.

■A DB-9 end of the Console cable attaches to the Netopia 4541/4542’s Console port.

■If you connect a PC with Microsoft Windows 95, 98, 2000, or NT, you can use the HyperTerminal application bundled with the operating system.

■If you connect a Macintosh computer, you can use the ZTerm terminal emulation program on the supplied Netopia 4541/4542 CD.
