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
R2121 CD. You install NCSA Telnet by simply dragging the application from the CD to your hard disk.
Connecting a local terminal console cable to your router
You can perform all of the System Configuration activities for your Netopia R2121 through a local serial console
connection using terminal emulation software, such as HyperTerminal provided with Windows95 on the PC, or
ZTerm, included on the Netopia CD, for the Macintosh.
The Netopia R2121 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, the serial port is called the Modem
port or the Printer port.) This connection lets you use the computer to configure and monitor the Netopia R2121
via the console screens.
To connect the Netopia R2121 to your computer for serial console communication, use the supplied dual
console cable connector end appropriate to your platform:
■one DE-9 connector end attaches to a PC
■the mini-DIN8 connector end attaches to a Macintosh
■the DE-9 end of the Console cable attaches to the Netopia R2121’s Console port
If you are configuring your router via a

terminal

session, your computer must be running a standard terminal
emulation or communications software program, such as those used with modems.
■If you connect a PC with Microsoft Windows 95 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 R2121 CD.
