Introduction

Welcome to the world of USB faxmodems. A faxmodem
equipped with a Universal Serial Bus, or USB, means con­venience, ease of installation, and high performance.

You can install your USB modem quickly, without both­ering with a separate power supply or having to worry
about your computer’s internal settings, as you might with
other types of external or internal modems.

Your USB faxmodem supports both the V.90 ITU Standard
and K56flex, the most widely used pre-standard 56K tech­nology. This way, your faxmodem automatically selects the
fastest compatible connection speed. You’ll find this fea­ture particularly valuable if you frequently access different
sites.

This Quick Start and Reference Guide provides easy,
step-by-step installation instructions for your new USB
faxmodem.

Introduction 5

Chapter 1: Setting Up Your USB Faxmodem

A computer has many devices inside it, or attached to it,
such as the mouse or the video card. These devices are
controlled by software called drivers. The USB faxmodem
also requires drivers. These drivers reside on the Zoom
Link CD, and are installable in a few simple steps.

Installing the Drivers

REMEMBER

IMPORTANT

Note: If you have a PC and are replacing an existing in-

ternal modem, turn to Appendix A: Removing a
PC’s Internal Modem (page 20) to decide whether

to keep or remove it.

If you have a PC:

Follow the instructions on the Zoom Link CD. An in-

1

stallation interface will display.

Click on the Install Drivers button.

2

Once your driver files are installed, a Setup Complete

3

dialog box will appear. Click Finish.

If you have a Macintosh:

Insert the Zoom Link CD.

1

A folder will appear with flags representing different

2

countries; double-click on the country you want.

You must install the modem drivers be-
fore you install the USB faxmodem.

Double-click on Zoom Installer and follow the

3

prompts.

6 Quick Start and Reference Guide

For both the Macintosh and the PC, the installation inter­face also provides for uninstalling the drivers, if you ever
need to.

One final note: Don’t install any of the other software on
the Zoom Link CD at this time.

Connecting the Faxmodem to Your Computer

Find the serial number of your faxmodem on the bot-

1

tom of the case, just under the bar code. Write the
number in the Important Information table on the last
page of this manual.

You do not have to shut down your computer. Connect

2

the cable. Plug the cable’s square end into the USB
jack on the back of the faxmodem. Plug the other,
rectangular end into the USB connector on your com­puter.

Your computer will display a message that it has de-

3

tected new software and is installing it.
Connect the telephone cord. Plug one end of the cord

4

into the PHONE LINE jack on the back of the faxmo­dem. Plug the other end into the wall jack just as you
would a standard telephone. You may also connect
your regular telephone to the back of the faxmodem, in
the jack labeled PHONE. See the following illustration.

The faxmodem works with or without a telephone con­nected to it.

• Double-check that the USB faxmodem is selected un-

der Settings.

Installing the Software

Consult the Software Installation Guide that came with
your faxmodem to install a complete faxing and communi­cations package that will help you get the most out of your
modem. Also explore the other software offerings on the
Zoom Link CD. The CD describes each program and offers
easy point-and-click installation.

That’s it! We hope you enjoy the use of your new USB
faxmodem.

Chapter 1: Setting Up Your USB Faxmodem 11

Chapter 2: Using the Faxmodem

If you have installed the fax and communication software
that came with your faxmodem, you probably do not need
to read this chapter. The software sets itself up automati­cally and takes care of sending any necessary commands
to the faxmodem.

You may, however, want to read this chapter if you want
to learn some general facts about how software works with
your faxmodem or if you intend to use your new faxmodem
with other software.

This chapter explains how to get Internet access, and pro­vides tips for setting up faxing and communications soft­ware, sending AT commands to the faxmodem, and using
a video camera.

Accessing the Internet

To access the Internet and the World Wide Web, use an
online service such as America Online (AOL) or Compu­Serve, or an Internet Service Provider (ISP). The best place
to start is your ZoomLink CD, which includes Internet
and online services for you to try.

Setting Up the Fax and Communications Software

Most software programs identify the modem automatically
and configure themselves for the correct operating set­tings.

Note: If you want to continue using software that had

been set up for a different modem, you may need to
reinstall the software or change its settings to run
with your new faxmodem. See the documentation
or help files of your existing software.

If you run into difficulty configuring or reconfiguring your
software, it may be helpful to read the following section,

Tips for Selecting Setup Options.

12 Quick Start and Reference Guide

Tips for Selecting Setup Options

In setting up some older software programs, you may be
asked to enter certain information. Most programs have
default settings that are correct for use with this modem,
and there is no need to change them. Nevertheless, you
should be aware of the following items:

• If you are asked to select the “modem type” from a

menu, and you don’t see this modem listed by name
on the menu (for instance, Zoom External V.90 56K
USB Faxmodem), select the most descriptive name
such as V.90 modem, 56K modem, or generic Class
1 fax modem.

• If you have a PC, in the dialing directory set all entries

to the highest possible baud rate, if your software sup­ports these speeds (do not go over 115,200). All com­munications between the computer and the modem
take place at this higher speed, independent of the
modem-to-modem speed.

• If your fax software gives you the option of selecting

Class 1 or Class 2 fax drivers, select Class 1.

Initialization Strings

An initialization string is a group of AT command settings
that the software sends to the faxmodem to initialize it.
Your software determines which commands should be in­cluded in the initialization string, based on the modem
you select during software installation.

Your software may send other AT commands to perform
actions such as dialing a phone number or answering a
call. This is transparent to you—the software does this in
the background without your having to be aware of it.

It is sometimes necessary, however, to add other AT com­mands to initialization strings. You can find a description
of AT commands on the World Wide Web at

www.modems.com. Click on Reference and then on AT
Command Sets.

Chapter 2: Using the Faxmodem 13

Here are two of the more useful AT commands:

• If your software suggests an initialization string for

this modem, you should use it. If this modem is not
listed by your software and no initialization string is
suggested, use the following: AT &F. This command
returns the modem to the default factory settings.

• If your phone service includes Call Waiting, an in-

coming call can disrupt your modem connection. You
can temporarily suspend Call Waiting by pressing *70;
if so, include ATDT*70, in the dial prefix option
(including the comma, which inserts a brief pause to
allow the phone company to respond). If your software
does not have a dial prefix option, you need to insert
the code for each phone number in the dialing direc­tory. If you need to dial a special code number, such as
9, to get an outside line, put the number (followed by a
comma) before the phone number.

Making the Most of the Fax and Voice Features

Your faxmodem includes software on the ZoomLink CD
that enables you to send, receive, and schedule faxes.

In addition, it includes software so that you can use your
computer and modem as a telephone answering machine
or voice mail system (with single or multiple mailboxes). If
you have a PC, the software will also let you set up fax­back, sometimes called fax-on-demand, and issue fax
broadcasts.

If you use your faxmodem for receiving faxes and voice
mail, keep in mind the following:

• Your computer must be running, and the communica-

tions software must be active.

• If you want to connect to your online service or ISP,

you must exit the communication software first. While
you are on line, you cannot receive calls or faxes.

• Some computers have a power saving option that stops

the hard drive from spinning after a period of inactiv­ity. If a call (voice or fax) comes in, it may fail to con-

14 Quick Start and Reference Guide

nect while the hard drive restarts and activates the
software. If this happens, you should deactivate the
feature of your power saving option that stops the hard
drive. See your computer's documentation for details.

Using Video

Your faxmodem supports video applications through the
V.80 standard protocol so that it can be used for high­quality modem-to-modem videoconferencing. The modem
is compatible with H.324 point-to-point and H.323 Inter­net video conferencing standards. To send videos, you
need a camera and video software. Zoom® Telephonics’
ZoomCam™ video camera devices add video recording and
transmission capabilities to your computer and work well
with your USB faxmodem.

Chapter 2: Using the Faxmodem 15

Chapter 3: Solving Common Problems

Note: If your modem is not working, please read this

chapter and Chapter 2: Using the Faxmodem on
page 12 carefully.

For installation problems, refer to Chapter 1: Setting Up
Your USB Faxmodem on page 6.

This chapter covers three categories: general trouble­shooting, dial troubleshooting, and on-line troubleshoot­ing.

General Troubleshooting

Problem: The software cannot find the modem and the

modem does not respond to AT commands.
(The following solution applies to many
other problems as well.)

Solution: The most common problem with modems is

that the communications software is not con­figured for the same COM port as the modem or
that the USB faxmodem is not selected under
the software.

If you have a PC, check which COM port the
modem is using and make sure that the soft­ware’s COM port setting matches the modem’s
COM port setting. From the Windows Toolbar,
under Settings/Control

Panel/Modems/Diagnostics, click on the COM
Port for your modem, then click on More info.

If Windows displays the modem’s ATI re­sponses, the modem is working.

If you have a Mac, make sure that the USB
faxmodem is selected under Settings in the
application software.

Problem: The modem speaker volume is too low or too

high.

16 Quick Start and Reference Guide

Solution: Your modem has a small speaker on its board

that gives you audible feedback of dial tones
and remote connection signals (“handshaking”).
This is not the same as the speaker that you
may have connected to your computer’s sound­card.

If the software allows you to control the volume
of the on-board speaker, make sure the speaker
is enabled and set to a comfortable volume.

If the software does not have speaker settings,
add one of the AT commands listed below to
the initialization string:

L1 for low volume
L2 for medium volume
L3 for highest volume
M0 to turn the speaker off completely
M1 to turn the speaker back on

For example, if you want the volume low and
the software uses the initialization string AT
&F, change it to AT &F L1.

Dial Troubleshooting

Problem: The modem does not automatically dial a

call when you send a Dial command.

Solution: Make sure the modem speaker is turned on in

your software so that you can hear dialing
sounds. Also make sure that the phone line is
plugged in.

Make sure that you are dialing a valid phone
number, including any required dial prefixes.

If you are using tone dialing on a line that re­quires pulse dialing, the line may not be able to
accept tone-dialed calls. Select Pulse dialing in
your software or make sure software dialing
prefix is ATDP (for pulse dialing).

Make sure your communications software and
modem are configured for the same COM port.

Chapter 3: Solving Common Problems 17

Make sure your modem has hung up from the
previous call. Select Hang Up in your software
or type ATH in terminal mode.

On-line Troubleshooting

Problem: Your modem disconnects while communicat-

ing with a remote system.

Solution: The remote system has hung up. You need to

reconnect.
The telephone line disrupted your call. If your

telephone service includes Call Waiting, turn it
off by including a special code in the dial prefix
(consult your phone company for details).

Someone may be picking up an extension con­nected to the line that your modem is using. If
the modem is sharing a telephone line with
other telephones, inform the other users when
you will be making a data call.

Line conditions may have deteriorated. Recon­nect.

Problem: Your online service or Internet connection

seems slow, Web pages appear slowly, and
file downloads seem to take too long.

Check your connection speed. Each time you
dial in, your call may be routed over different
lines. Logging off and redialing can sometimes
give you a better connection. With V.90 or
K56flex sites you should be able to obtain
speeds between 42,000 and 52,000 bps.

If your ISP or online service provides more than
one number, try another one. Some are faster
than others.

Try different Web pages. Some very popular
pages have a lot of traffic and may be slow, es­pecially in the evening.

18 Quick Start and Reference Guide

Problem: Your modem does not make a connection.
Solution: If your modem places calls but never makes a

connection, make sure you are dialing the right
number.

The remote modem may be turned off.

Chapter 3: Solving Common Problems 19

Appendix A: Removing a PC’s Internal Modem

If your PC does not already have an internal modem in­stalled, or if you are replacing an external modem, you do
not need this section.

Appendix B: Regulatory Information

FCC Part 15 Emissions Statement

This modem has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These lim­its are designed to provide reasonable protection against harmful inter­ference in a residential installation. This equipment generates, uses and
can radiate radio frequency and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio commu­nications.

However, there is no guarantee that interference will not occur in a par­ticular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the inter­ference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that

to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

FCC Part 68 Telecommunications Statement

The Federal Communications Commission (FCC) has established rules
which permit this device to be directly connected to the telephone net­work. This device is registered with the Federal Communications Com­mission (FCC) for direct connection to the telephone line using a stan­dardized RJ-11C telephone jack. This device complies with the Part 15,
Subpart B, and Part 68 requirements of the FCC rules.

The telephone company may make changes in its technical operations
