Introduction

Congratulations! Your 56K Faxmodem is a powerful, flexi-

ble tool that will help you manage your communications,

work more efficiently, and present a polished and profes-

sional image at home or at the office.

This product includes high-speed data and fax capability

with the ability to receive data from compatible central

sites at speeds up to 56 Kbps, and even higher rates

using data compression.

As discussed in Appendix A, your faxmodem’s ability to

achieve speeds above 33,600 bps depends on your calling

a compatible central site such as a compatible Internet

Service Provider (ISP), online service, or corporate net-

work. It also depends on the characteristics of the phone

line connecting your modem to the local telephone office.

Your 56K Faxmodem can also perform as a top-of-the-line

V.34 data and fax modem, operating at speeds up to 33.6

Kbps.

This manual is primarily an installation, troubleshooting,

and reference guide. Once you have successfully installed

the modem in your IBM PC-compatible computer,

software controls virtually all access to the fax and data

product features.

While many data communications features can be con-

trolled using AT commands and S registers, there is

rarely any reason to do so. The software shipped with this

product allows you to change your modem’s configuration

and to control the communications features easily.

Summaries of AT commands and S registers have been

included in this manual primarily for programmers and in

the interest of tradition and completeness.

The use of AT commands and S registers is neither re-

quired nor recommended for the average user.

656K Faxmodem Owner’s Manual

This owner’s manual is organized as follows:

Introduction (this section) lists the items you will need

to use the modem.

Installation (Chapter 1) explains how to install the modem.

Using the Faxmodem (Chapter 2) provides tips for

setting up your software.

Problems and Solutions (Chapter 3) provides

information to assist you if you have problems.

The Appendixes provide additional information for a

number of topics including tables that summarize AT

commands and S registers.

Follow the Quick Start guide’s instructions for quick in-

stallation of the hardware and software that is included

with this product. If you have questions that are not an-

swered in the Quick Start guide, follow the instructions

provided with your fax and data communications software

to install and use those programs.

What You Need to Use Your Faxmodem

Make sure that you have received the following

items:

• Faxmodem

• Phone cord

• Power adapter (for external models only)

• Fax and data communications software on floppy

disks. These floppies also contain some helpful

installation utilities for non-Plug and Play systems.

To use the faxmodem, you also need the

following:

• For internal models, a computer with an available

IBM PC-compatible 16-bit ISA or EISA Bus slot.

• For external models, an available serial port (also

called an RS-232 port, COM port, or modem port).

Introduction 7

• A serial cable with hardware flow control (external

model only).

• A telephone line connection (typically, a wall-mounted

telephone jack or socket) that lets you plug in a

single-line telephone.

• A tool, if necessary, for removing and putting back the

computer cover (internal model only). (See your

computer’s manual.)

Documentation Conventions

• In this manual we may use the terms “faxmodem,”

“modem,” and “product” interchangeably.

Occasionally you may find that other manuals use the

term “modem board” or “card” to refer to the modem.

• Commands and command examples described in this

guide appear in bold type. For example: To reset the

modem, type ATZ and press Enter.

• Occasionally we insert spaces between commands to

make a command line easier to read. You can type the

command line with or without spaces between

commands as long as the command line does not

exceed 40 characters.

• “0” in a command line indicates the number zero, not

the letter “O”.

Chapter 1 Installation

This chapter explains how to install external and internal

faxmodems.

Installing an External Faxmodem

To connect the external faxmodem

Turn off the computer.

Connect the faxmodem-to-computer cable. Plug one

end of the cable into the wide connector on the back

of the faxmodem. Plug the other end into the serial

port in the back of your computer.

Connect the telephone cord. Plug one end of the

cord provided with the modem into the PHONE LINE

jack on the back of the faxmodem. Plug the other end

into the telephone line connection (typically mounted

on a wall), just as you would a standard telephone.

You can plug a telephone into the faxmodem’s other

jack, marked PHONE. The faxmodem works with or

without a telephone connected to it.

Connect the power adapter. Plug one end of the

power adapter into the back of the faxmodem. Plug

the other end into an available electrical outlet. You

can leave the power adapter plugged in when you are

not using the faxmodem.

CONNECTION

Turn the computer back on.

Turn the faxmodem on by pushing in the power

button on the front, as shown in the illustration

below.

The modem performs a brief self-test.

After the self-test, the front panel status lights or

LEDs show the faxmodem’s current state. The MR

light should be on, which shows the faxmodem is

ready for use.
