Introduction
Congratulations! Your new faxmodem is a powerful, flexible tool that provides fast connections to the Internet and
will help you manage your communications, work more
effectively, and present a polished and professional image
at home or at the office. This manual explains how to install and use your faxmodem and communications software.
What You Need to Use Your Faxmodem
Make sure that you have received the following items:
• Faxmodem
• Phone cord
• A Zoom Link CD-ROM disc containing installation
software, modem drivers, and communications software.
You also need the following:
• IBM PC-compatible Pentium® 133 or faster (or equiva-
lent), with 16 megabytes of RAM, an available PCI slot,
and a tool for removing and replacing the computer
cover (see your computer’s manual)
• Windows® 95 or 98 operating system
• A telephone jack to plug the modem into
• A soundcard and microphone if you want to use the
modem as a telephone answering device (voice mail
option)
Introduction 3
Chapter 1 Installing Your Faxmodem
Easier Installation
We have enhanced the plug-and-play capability by providing a software program that you must run before you
install your faxmodem. This program installs “driver” files
and sets up your computer to recognize the new faxmodem.
When you restart your computer after installing the faxmodem, your hard drive will already contain the files Windows needs to complete the installation.
Preparing the Computer
For the moment, put the faxmodem aside—you don’t even
need to get it out of its antistatic bag. Follow these steps:
Close any applications you have running.
1
Find the Zoom Link CD-ROM disc that came with
your faxmodem and insert it in your CD-ROM drive.
The CD-ROM disc should auto-run after a few seconds and display an installation screen.
If the CD does not auto-run:
• Click on My Computer on your desktop; then
double-click on the icon for your CD-ROM drive.
• If the installation program doesn’t start up right
away, double-click on Zsetup.exe.
When the installation interface appears, click on the
2
Install PCI Modem button. The installation program
will run and automatically copy driver files to your
hard drive.
There may be other programs on the CD, including
3
Internet Service Providers, online service offers, and
a communications package, and games. Do not install these programs until you have completed your
faxmodem installation. Some of these programs
4 Quick Start and Reference Guide
must detect your modem settings in order to complete their setup routines.
When the PCI modem installation program has finished, remove the CD from its drive and shut down
your computer.
Installing the Faxmodem Card
CAUTION
Do not handle any internal modem card when the phone
line is plugged into it. The voltages present when the line
is ringing are potentially harmful.
Electrostatic Discharge Protection
Static electricity can damage components on
your faxmodem or inside your computer.
Before removing the board from its antistatic bag, touch the computer’s metal
CAUTION
chassis to statically discharge yourself.
Note: If you have not already run the modem installa-
tion program on the CD-ROM disc, please do so
now—before you install the faxmodem card. See
Preparing the Computer on page 4
1
Chapter 1 Installing Your Faxmodem 5
If your computer does not already have a modem
installed, go to step 3.
If your computer has a modem, you may choose
to keep it or to remove it. We recommend that
you remove your old modem unless you have a good
reason to keep it. Removing your old modem assures that your computer will have enough resources to run your new modem without conflicts
with other devices.
You may want to keep your old modem, however, if
you have two telephone lines and want to keep your
fax program running on one line while you access
the Internet on the other line. Another reason for
keeping your old modem would be that you anticipate being able to use “teaming” or “bonding” software to use two modems and two phone lines for
faster Internet access.
2
If you are removing your old modem:
Please refer to your modem manufacturer’s removal
instructions, if any. The following procedure should
work in most cases.
Note: You can also use this procedure if you ever
need to remove or relocate your PCI faxmodem.
If you are simply relocating your PCI
faxmodem to a different PCI slot, you
must follow the procedures in this step and
then rerun the installation software
(Preparing the Computer, on page 4) before reinserting the PCI faxmodem in a new
slot.
Before you remove your old modem, you must inform Windows 95 or 98 that you are going to remove it before you physically do so. This helps to
prevent internal conflicts in Windows 95 as it allocates its resources to your new faxmodem.
Follow these steps:
• Click on Start and point to Settings. Click on
Control Panel. When the Control Panel dis-
plays, double-click on the System icon.
• Click on the Device Manager tab. Scroll down
to the Modem entry.
• Click on the + sign in the little box next to this
entry to expand it. Find your existing modem in
the list and click on it by highlighting it.
• Now click on the Remove button. Click OK to
confirm that you are removing the modem.
Windows has now been informed of your intention
6 Quick Start and Reference Guide
to remove the old modem. Continue with step 3 below.

Before you start the hardware installation, close
all running programs and shut down Windows if
you have not already done so. Then turn your
computer off and unplug it. Don’t plug it back in
or turn it on until you complete the faxmodem
hardware installation.
Take the cover off your computer. If you are not familiar with the procedure, consult your computer’s
manual for instructions.
Unscrew and remove the metal cover plate on the
rear of the computer that lines up with an available
PCI slot. The PCI slot is shorter than a 16-bit ISA
slot and usually a different color (ISA slots are typically black or brown; PCI slots are usually white or
gray). Your faxmodem has two sections of gold connecting fingers, and a PCI slot has two sections that
match the sections on the faxmodem.
If you are replacing an older modem, now is a
good time to remove it. (It may be in a non-PCI slot,
which you cannot use for your new faxmodem.)
Look for an add-in board with one or more phone
jacks on it. To remove the old modem, first unplug
any phone cords connected to it. One cord is probably the connection to your telephone. You can reuse
this connection with your new faxmodem. The other
cord is probably the connection to your telephone
line at a wall jack. It is a good idea to replace this
cable with the one that came with your new faxmodem.
Unscrew the screw on the bracket and lift the old
modem board from its slot.
Note: Most of the boards inside your computer
have tiny wires sticking out underneath. These
wires can be sharp. Be careful not to cut your
hands on them.

Chapter 1 Installing Your Faxmodem 7
Make a note of the serial number on your new faxmodem. Record the number in the Important In-
formation table on page 32 of this manual.
Now insert your new faxmodem firmly into an avail-
LINE
able PCI slot. See the following illustration.
PCI slot

Typical cover
plate
16-bit
ISA slots
The PCI slot is designed to easily mate with your
new PCI modem.
Be sure that the bracket is lined up properly; then
screw the bracket into the computer using the
screw you removed with the cover plate. Be sure
that the back end of the card (smaller gold finger
area) is properly seated into the connector. If you
have a tower or mini-tower computer case with a
vertical main board, you may want to lay the computer down gently on its side so you can push
straight down on the faxmodem card to seat it
firmly in its slot.
Replace the computer cover.
Connect the telephone cord. Plug
one end of the phone cord into the
LINE
jack marked LINE. Plug the other
end into a phone jack (typically the
wall jack where you would normally
PHONE (optional)
PHONE
connect a phone). Plug your phone
into the PHONE jack if you want to
use a phone on the same line.

Plug in your computer and turn it on.

11
As the Windows operating system starts up, it will
detect your new faxmodem. Because the installation
program has already provided your computer with
the required files, you will see Windows report on
its progress, but it will not require any action on
your part.
Once the system has completely started, you should
determine what COM port your faxmodem is set to.
The COM port is a number used by the computer to
keep track of where it is sending data. You may be
asked for this number by certain software applications when you install them and set them up.
To find your COM port number, double-click My
Computer. When the My Computer window opens,
double-click the Control Panel. Inside the Control
Panel window, double-click Modems. In the Modems
Properties dialog box, click on the entry for your new
modem, which should be listed as a modem found by
the system.
Then click Properties. Your faxmodem’s properties
are listed in a Properties dialog box. Under the Gen-
eral tab you’ll find Port: Com plus a number. Make a
note of this Port: Com setting on the Important In-
formation table on page 32 of this manual.
Note: PCI devices, including your new faxmodem,
use COM ports differently from the way
older ISA devices use them. Software applications will always associate the COM port
number with the “traditional” IRQ used for
that COM port even though Windows uses a
different IRQ internally. The IRQ listed for
the COM port in the Control Panel System
dialog should not be used in configuring
software. This may mean that DOS programs running under Windows will occasionally report an IRQ assignment that is
different from what is reported by Windows.
In nearly all cases, you can accept the default assigned by your software.

If you have not encountered any problems, your
modem is installed and you can move on to Testing
Your Faxmodem, below. If you are having installation problems, see Chapter 4.
Testing Your Faxmodem
Before you set up your software, start with a quick test to
check that your modem is working.
Open the Control Panel and double-click Modems. Under
the Diagnostics tab highlight the COM port for your modem and click More Info. This queries the modem with AT
commands. A list of responses means the modem is connected. You may also want to use HyperTerminal or another terminal program to call a bulletin board system.
Once you have determined that your faxmodem is working
properly, go on to Chapter 2 to install your communications software.
If you determine that your faxmodem is not working, first
try shutting down your computer and restarting it. Sometimes this will help Windows 95 or 98 identify and activate
the correct drivers. If restarting your computer doesn’t
work, read Chapter 4, Problems and Solutions.

Chapter 3 Using the Faxmodem with Other
Software
This chapter provides tips for setting up communications
software, sending initialization strings containing AT
commands to the faxmodem, using audio features, using a
video camera, and accessing the Internet.
Tips for Setting Up Communications Software
Software programs are designed to provide a simple, userfriendly interface that makes it easy to use the many features your faxmodem offers. First, however, the software
must identify the modem and its special capabilities. Many
software programs identify the product automatically and
configure themselves for the correct modem settings. If
you run into difficulty with configuration, it may be helpful
to read the following section, Tips for Selecting Setup
Options.
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. However 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 (Zoom PCI 56K HCF Faxmodem), select
the most descriptive name such as Rockwell Based
V.90 Modem, Rockwell Based K56flex modem, Generic IS-101 modem, Hayes-compatible modem
(with or without a specific speed), or generic Class 1
Modem. The more generic the type you choose, the
less likely that the software will let you use some of the
faxmodem’s advanced features, but the modem will
perform basic communications and fax functions.
• • In the dialing directory, set all entries to the highest
possible baud rate, if your software and serial port
support these speeds. All communications between the
16 Quick Start and Reference Guide
computer and the modem take place at this higher
speed, independent of the modem-to-modem speed.
The modem auto-negotiates the highest speed connection between itself and the other modem.
• If there is a section of your software called “Terminal
Settings,” make sure that Hardware Flow Control
(RTS/CTS) is ON (or YES). This is necessary in order
for V.42bis file transfers to work.
• • Set auto baud detect to OFF (or NO).
• If your fax software gives you the option of selecting
Class 1 or Class 2 fax drivers, select Class 1.
• Finally, some programs ask Send init if CD high?,
which you should set to YES. Otherwise, the modem
may not receive the proper initialization string.
Initialization Strings
An initialization string is a group of AT command settings
that are sent to the faxmodem as soon as you start up the
software. (The “AT” stands for “attention.”) The software
determines which commands should be included in the
initialization string, based on the device you select during
installation. The commands remain in effect throughout
the communications session, unless the software sends
other commands to override them.
The software uses other AT command strings for all commands sent to the modem. 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 table of AT
commands on the World Wide Web at www.modems.com.
Click on Reference and then on AT Command Sets.
Here are two of the more useful 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.
Chapter 3 Using the Faxmodem with Other Software 17
• • If your telephone service includes Call Waiting that
you can temporarily suspend by pressing *70, include
ATDT*70, (including the comma) in the dial string.
Using AT Commands
If your software does not handle AT commands automatically, it should provide a place to enter AT commands in
its setup menus.
However, in some cases you may need to enter AT commands directly to the faxmodem. You must do so from a
data program’s terminal mode.
To use AT commands in terminal mode:
1. Start your data communications program.
2. Change to terminal mode (also called command, lo-
cal, direct, or dumb mode).
The Windows operating system includes a terminal
application, HyperTerminal, which you may use if
you do not have a communications program. (Check
your operating system’s user’s guide for setup instructions for the terminal program.)
3. Type in the AT command you need and press Enter.
You will see an OK response.
When you finish, you can return to the data communications program’s standard user interface. See the software
program’s documentation if you need help.
Returning to the Factory Settings
To return to the factory default settings for the modem, in
terminal mode, type AT &F and press Enter.
Using Audio Features
In addition to data and faxing capabilities, your faxmodem
supports a full-featured single or multiple mailbox voice
mail system. Through your software you can also set up
fax-back, sometimes called fax-on-demand, and locally
and remotely record and play back messages. The communications software that comes with your faxmodem,
COMMUNICATE! LITE, is capable of these features. Other
18 Quick Start and Reference Guide
software that supports these features must be TAPI compatible (TAPI stands for Telephony Application Programming Interface) or support IS-101 commands. An example
of a TAPI-compatible software that supports voice mail is
Microsoft Phone™.
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 also
need video capture capability, a camera, and video software. The Zoom/Video Cam and the Zoom/Video Cam PPC
(parallel port camera) work very well with your faxmodem.
To include sound with your videos, you also need a soundcard and a compatible microphone.
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). ISPs typically
supply or suggest the browser software needed to access
their service.
Your faxmodem may include a packet of online service offers, which provide you the opportunity to try the Internet
and a range of other services.

Chapter 4 Problems and Solutions
Note: If your modem is not working, please read this
chapter and the communications software documentation in Chapter 3 carefully.
Also, the modem drivers for your faxmodem are
updated periodically to enhance performance or
features. You may want to download the latest
drivers from time to time, especially if you are encountering problems. A flyer included with your
faxmodem includes a Web address for driver updates.

General Troubleshooting
Problem: Your modem seems to install under Windows
95 or 98, but Windows cannot find it later.
Solution: If your computer has a built-in modem on the
motherboard, Windows may reinstall it the next
time you start up. Consult your computer’s
documentation or call your computer’s manufacturer to get instructions on how to disable
the built-in modem.
Problem: The software cannot find the modem and the
modem does not respond to AT commands.
(The following comment applies to many
other problems as well.)
Solution: The most common error with modems is that
the communications software is not configured
for the same COM port as the modem. Check
which COM port the modem is using. Make
sure that the software’s COM port setting
matches the modem’s COM port setting.
Another problem is that COM port resources
may be in use by another device. Make sure
that the COM port resources used by the modem are not being used by any other device,
such as a soundcard.
Problem: You type an AT command line in a terminal
application and press Enter, but your modem fails to execute the command line. Or
there was no response after executing a
command.
Solution: Be sure you type AT at the beginning of the
command line.
Make sure the communications software is con-
figured for the same COM port as your modem.
Be sure your modem is not in data mode when
you type the command. Use the escape character sequence to switch to terminal mode. (The
default escape sequence is to wait at least one
Chapter 4 Problems and Solutions 21
second, type +++, and wait another second or
more.)
If you typed a command but did not receive an
OK response from your modem: The E0 and Q1
commands may be in effect, disabling echo and
responses. Verify this with the &V command.
To enable echo and responses type AT E1 Q0
and press Enter.
Problem: You encounter other communication prob-
lems with your modem.
Solution: Check that your communications software has
been set up properly. Recheck the initialization
string and dial string specified in your software
manual. Remember that commands in the initialization string are sent to the modem each
time you start your software and override the
settings stored in the modem’s non-volatile
memory.
Memory-resident (Terminate-and-StayResident, or TSR) programs can cause a variety
of problems for some programs. Try starting up
your computer without them. You may find
TSRs in your AUTOEXEC.BAT file or in
WIN.INI. In AUTOEXEC.BAT, put rem
(“remark”) at the beginning of any line you
want to keep from loading. In WIN.INI, put a
semicolon (;) at the beginning of any line you
want to keep from loading. Examples of TSRs
include antivirus programs and screen savers.
If you are using Dial-Up Networking for Windows 95 or 98, you may want to download and
install the latest version. At the time this manual was printed, the latest version was available from Microsoft at
www.microsoft.com/Windows95/info/
dialup.htm.
Problem: The modem speaker volume is too low or too
high.
Solution: If the software allows you to control the vol-
ume, make sure the speaker is enabled and set
to a comfortable volume.
22 Quick Start and Reference Guide
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
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.
Make sure your modem has hung up from the
previous call. Select Hang Up in your software;
or type ATH in terminal mode.
Voice Troubleshooting
Problem: Voice features do not work, or they work
poorly.
Solution: The PCI faxmodem is designed to work with
voice software that is compatible with Windows
TAPI (Telephony Application Programming Interface) or with software that uses IS-101
Chapter 4 Problems and Solutions 23
commands (IS-101 commands are sometimes
called +V commands). Consult your voice software’s documentation to determine whether it
supports TAPI and/or IS-101. Also, be sure you
are using the latest 32-bit version of the software.
Another possible problem is that your computer
does not have the latest version of Unimodem
V, a set of drivers required for TAPI applications. The software that installs your faxmodem
automatically installs the latest version of
Unimodem V if it is needed. You may have
subsequently installed a communications
package that automatically installs an older
version of Unimodem V. If that is the case, you
can reinstall the newer version of Unimodem V

On-line Troubleshooting
Problem: The modem can connect to some modems,
but not to others.
Solution: A remote modem does not respond because of
the extended negotiation process by which modems determine the best common connection
between them. If this is the case, you may have
to disable part or all of the negotiation process.

Note 3: Some software allows these commands to be
added to the list of dial prefixes.
There are other configurations that can be forced as well.
If you need to select a particular configuration, use the AT
command strings shown below. You can always return to
the modem’s default configuration by typing AT &F and
pressing the Enter key. Remember that if you do this, the
modem will not have received the commands in your software’s initialization string as it normally would. Using the
ATZ command overcomes this problem if you have saved
all of your setup parameters in nonvolatile memory. (To
save setup parameters in nonvolatile memory in AT terminal mode: Type AT, followed by the parameter settings you
choose, followed by &W, and press Enter. For example, if
you type AT &C1 &D2 &W and press Enter, the &C1 and

Problem: Your online service reports a connect speed
that doesn’t match your modem’s speed.
Solution: First make sure the maximum speed setting is
as high as your computer system allows: In
Control Panel, open Modems and click on
Properties. Set the Maximum speed setting to
the highest setting.
If you have set the maximum speed to its high-
est setting and are seeing a connect speed that
is faster than your modem’s published speed,
your software is reporting the internal, computer-to-faxmodem speed. To get your online
service software to report the actual connect
speed, add this command to the end of the initialization string, or to the dial prefix, just before the D, as in these examples:
Initialization string: AT&F&C1&D2S95=1^M
Dial prefix: ATS95=1D
Consult your online service’s documentation for
details on initialization strings and dial prefixes. Actual connect speeds depend on your
modem’s speed, the equipment you’re connecting to, and phone line conditions.
26 Quick Start and Reference Guide
Problem: Your modem disconnects while communicat-
ing with a remote system.
Solution: The remote system has hung up, and you need
to reconnect. The other most common sources
of interruptions are Call Waiting or someone
picking up an extension phone.
If you have Call Waiting, you can usually temporarily disable it by including *70, (including
the comma), or by selecting it as a prefix, in the
software’s dialing directory.
You cannot disable Call Waiting for incoming
calls. If your incoming data calls are frequently
disrupted by Call Waiting, you should consider
dropping the service or installing a separate
phone line without Call Waiting.
Problem: Your modem does not make a connection.
Solution: If your modem places calls but never connects,
make sure you are dialing the right number
and that the remote modem is turned on.
Problem: You receive bursts of errors occasionally, but
otherwise data quality is good.
Solution: The connection may have been established on
poor-quality or noisy telephone lines. Hang up
and place the call again to try to obtain a better
connection.
Someone may be picking up an extension connected to the line that your modem is using. If
your modem is sharing a telephone line with
other telephones, inform the other users when
you will be making a data call, or install a
separate line dedicated to data calls.
Your telephone line may have a Call Waiting
feature and a call is being received. See the Call
Waiting discussion on page 27.
Problem: Random errors occur or data is missing in
transmitted data.
Solution: Use the MNP or V.42 protocol if the remote mo-
dem supports one of these protocols. See the
table on page 26 for more information.
Select a lower baud rate in your communications software and place the call again.
Chapter 4 Problems and Solutions 27
If both modems are using the MNP or V.42
protocol, the only way this can occur is if your
modem and communications software are not
using the appropriate flow control. Configure
your communications software for RTS/CTS
(hardware) flow control. Your computer will
now pause for the transmission to be stored.
Problem: Modem performance seems sluggish.
Solution: If you are connected to the Internet, there may
be a lot of “traffic” at the Web sites you are visiting. Other possible causes are lack of sufficient memory in your computer (16 megabytes
of RAM required) or a slow processor (you need
a Pentium® 133 or faster, or equivalent).
Problem: Data appears garbled on the screen.
Solution: Your communications software character set-
up (start bit, data bits, stop bits, and parity bit)
does not match that of the remote system.
Check your settings against those used by the
remote system and make sure they match. Pay
particular attention to the parity setting, as
this is the most common difference among
systems. You should normally use 8 data bits,
NO parity, and 1 stop bit (8, NONE, 1 or 8N1).
The second most common setting is 7 data bits,
EVEN parity, and 1 stop bit (7, EVEN, 1 or
7E1).
Problem: Your modem doesn’t seem to be compress-
ing the data.
Solution: The compression features are on by default, but
check the following:
Your software needs to use a streaming proto-
col, such as Ymodem-G or Zmodem. Xmodem
and Ymodem are not adequate for compression.
Your software must be set up to use hardware
flow control (RTS/CTS ON).
Be aware that many files downloaded from online services have already been compressed. In
general, your modem will not be able to further
compress such files.

Items (2) and (4) are indicated on the label attached to the bracket. The
ringer equivalence number is used to determine how many devices can
be connected to your telephone line. In most cases, the sum of the RENs
of all devices on any one line should not exceed five (5.0). If too many
devices are attached, they may not ring properly.
If this device should malfunction, it may also cause harm to the telephone network; should this occur, this device should be disconnected
from the network until the source of the problem can be determined and
repair has been made. If a device which harms the network is not removed, the telephone company may temporarily disconnect service.
In the event of equipment malfunction, all repairs should be performed
at an authorized repair facility. It is the responsibility of users requiring
service to report the need for service to such a facility. Service facilities
are listed on the product’s warranty flyer.
The Telephone Consumer Protection Act of 1991 makes it unlawful for
any person to use a computer or other electronic device to send any
message via telephone fax machine unless such message clearly contains in a margin at the top or bottom of each transmitted page, or on
the first page of the transmission, the date and time sent, the identification of the business, entity, or individual sending the message, and the
telephone number of the sending machine. In order to program this information into your fax machine, refer to your faxmodem software
documentation for information on enabling fax branding.
