Additional Equipment Required

In addition to the items supplied with the modem, you may need the following:

Communications Software Package

Many modem applications are controlled by communications software that
supports serial communications. When connecting a modem to a terminal,
communications software is unnecessary. (Refer to Chapter 3 and Chapter 4 for
more information.)

Serial Cable

A shielded, straight-through modem-to-terminal cable, data communications
equipment (DCE) to data terminal equipment (DTE) cable, is required.
The cable must have a 25-pin D male connector and a DTE connector.

For modem-to-modem (or other DCE-DCE connection), use a crossover cable.

The cable must support the modem signaling your application requires. Select a
cable based on your computer and the DTE pin assignments in Appendix B.

Choosing a Site

Where you place the modem can affect its operation. To enhance performance:

• Install the modem in a clean, well-lighted area that is free from temperature

extremes and dust.

• Do not place anything on top of a modem.

• Locate the modem no more than the EIA-recommended distance from a DTE

and within 6 feet (1.83m) of a grounded AC power outlet.

• Do not place anything within 1 inch (2.54 cm) of either side of a modem. Also,

to prevent overheating, do not place a modem on its side.

Refer to Appendix C for site requirements for operating the modem in your country.
