Telephone Line

You must have a telephone line with a jack (connector) that accepts the cable that
comes with the modem. If you do not have a telephone jack near your computer,
you should install one before proceeding.
In North America, do-it-yourself telephone extension kits and accessories are avail-
able wherever telephones are sold. You may also hire an independent contractor or
your local telephone company to install an extension. If you want a separate line for
your fax modem, you must contact your telephone company.

Communications Software

To operate your modem, you must have a data, fax, and voice communication pro-
gram, such as the one included with your modem. Communication software simpli-
fies control of the modem by guiding you through the process of selecting your
serial port, your port speed, and other variables, and then storing your settings, in-
cluding frequently called phone numbers, so they can be recalled with the stroke of
a key or the click of a mouse. Communication software must be set up, or config-
ured, before you can use it.

Connections

To use your modem, you must connect it to your computer ("RS232"), to a telephone
line ("LINE"), to a telephone ("PHONE"), and to a power source ("PWR").

Connecting to the Computer ("RS232")

Using a matching serial cable, connect the RS232 connector on the modem to one of
the serial port connectors on the back of your computer. On a PC, there are usually
two serial ports named "COM1" and "COM2." COM1 typically uses a DB-9 connec-
tor, whereas COM2 may use a DB-25 connector. Most Apple Macintosh computers
use round mini-DIN-8 connectors for the serial ports. Choose the one marked with
the icon of a telephone; the Macintosh gives priority to that port and will not inter-
rupt your communications link. Be sure to tighten the mounting screws on the DB
connectors.

Connecting to the Telephone Line ("LINE")

Plug one end of the cable provided with the modem into the telephone jack in your
home or office. Plug the other end into the LINE jack on the modem.
