Installing Your Modem
To install your Courier 56K Business Modem, do the following three simple steps:
- Configure your Courier 56K Business Modem with DIP (dual in-line package) switches
- Connect the cables
- Install the drivers
Step One: Configuring with DIP Switches
Depending on how you plan to use your modem, you may need to change your DIP switch settings. See the “Configuring your Modem with DIP Switches” section of this guide for more information. The DIP switches 3, 5, 8, and 9 are in the on (down) position. (The DIP switches are located next to the phone jacks on the bottom of the modem.)
Step Two: Connecting the Cables
Note: If you plan to connect your Courier 56K Business Modem to a mainframe computer or use your modem to dial in to a mainframe computer, you will find more technical information on the Installation CD-ROM that comes with your new modem.
- Make sure that your computer is turned off before you begin installing your new modem. Connect the RS-232 modem cable to the back of the modem and to your computer’s serial port. Clip the ferrite clamp around the end of the RS-232 cable that is connected to the modem.
- Plug one end of the included phone cord into the
jack on the back of the modem and plug the other end into an analogue
telephone wall jack. If there is another phone jack on your modem, you
can use a telephone by plugging the telephone’s cord into the modem’s
jack. Plug the power
adapter into the modem’s 
jack and into a surge protector or electrical outlet. Make sure to use
the power adapter that came with your modem, as others may be of different
voltages and could damage your modem.
Turn on the modem by pressing the button on the back of the modem. The CTS and MR lights should illuminate.
- If the CTS and MR lights do not illuminate or other lights illuminate, make sure that only DIP switches 3, 5, 8, and 9 are in the on (down) position. (DIP switches are located on the bottom of the modem.)
- Turn on the modem.
To find the serial port on the back of your computer, look for COM, MODEM, RS-232, IOIOI, or SERIAL. Do not use the AUX, GAME, LPT, or PARALLEL ports.
