Installation
This chapter covers the steps required to install your modem and install and configure
the Windows 95 driver.
1. Turn off your computer.
2. Open the rear panel on the back of your modem.
3. Connect the power adapter. Plug one end of the power adapter to the round
POWER JACK on the back of the modem. Plug the other end to an AC wall outlet.
You can leave the power adapter plugged in when you are not using the modem. To
prevent power surges from damaging your modem and computer, it is recommended
that you connect the power adapter to a surge protector.
4. Connect the serial cable. Plug one end of the serial cable into the SERIAL PORT
connector on the back of the modem. Plug the other end of the serial cable to the
back of your computer. Your Comet 336 comes with a high-speed serial interface
capable of reaching DTE speeds of 115.2Kbps. Be sure that your PC serial port has
a high-speed 16550 compatible Universal Asynchronous Receiver Transmitter
(UART).
5. Connect the telephone cord. Plug one end of the supplied telephone (RJ-11) cord
into the LINE jack on the back of the modem. Plug the other end into a telephone
wall jack, just as you would a standard telephone.
6. Turn the Comet 336 on by raising the blue power switch. The PWR LED should
come on and the modem performs a self-test procedure.
7. Turn the computer back on.
