Installing on a Windows Computer
Connecting the Modem to Your System
Turn off your computer. Place the modem in a convenient location, then connect it to your computer’s serial port,
to the phone line, to AC power, and to your phone (phone is optional).
1. Connect the Modem to Your PC (RS-232 Connection).
Plug one end of the RS-232 serial cable into the RS-232 connector on the modem, and plug the other end into
a serial port connector on your computer.
2. Connect the Modem to the Telephone Line (Line Connection)
Plug one end of the phone cable into the modem’s LINE jack and the other end into a phone wall jack. The
phone cable is included with your modem.
Note: The LINE jack is not interchangeable with the PHONE jack. Do not plug the phone into the LINE jack
or the line cable into the PHONE jack.
3. (Optional) Connect the Modem to the Phone.
For voice-only calls, plug a phone into the modem’s PHONE jack.
4. Connect the Power
Make sure the power switch is set to OFF. The power switch is located on the side panel of the modem.
Plug the power supply into a power outlet or power strip. Plug the other end into the PWR jack on the
modem.
CAUTION: Use only the power supply cable supplied with the modem. Use of any other power supply voids
the warranty and can damage the modem.
