Introduction

Your new modem will allow you to quickly communicate with most
modem-equipped computers in the world. You can transfer files to
your office or home or connect to an Internet Service Provider (ISP)
or online service such as CompuServe or America Online.

We designed this manual to make connecting your modem as easy
as possible. The communications software, included in your modem
package, provides menus to use your modem once it is installed.

Important Note on Modem Throughput

Your Hayes 56K modem is capable of download speeds of 56Kbps
when connected to an ISP or remote access server supporting V.90
or K56flex. Still, like other modem speeds, actual modem
throughput (the actual speed of data transfer) is dependent on
analog telephone line conditions, which vary considerably. Many
users of 56K modems will experience throughput in the range of 42­56Kbps under normal conditions—again, depending on phone
quality.

Please do not interpret throughput speeds of less than 56Kbps as a
modem problem, because it is most likely a function of telephone
line conditions and Internet traffic.

Connecting your modem may be your first introduction to COM ports
and IRQs. If you are connecting your modem to a Macintosh-based
computer or a PC using Windows 95 or 98, your computer handles
COM ports and IRQs for you. However, with other computers or
software, you must select a COM port and IRQ yourself. COM port
and IRQ settings are discussed later in this guide.

Before You Get Started...

Please read the Regulatory & Warranty Information.

Introduction 1

What You Need

To install and operate the modem, you will need the following items.

They are included in your modem package.

Communications software provides menus that allow you to set up
and use your modem to connect to other computers and go online.

• Telephone Cable

Your modem is designed to operate over a standard telephone
line through its telephone cable connection. Do not connect the
modem to a party line or coin-operated telephone line.

2 Hayes Modem Installation Guide

External Modems Also Need....

• Serial Cable

Ask your computer store dealer for a shielded, straight-through
modem cable to connect the modem to your computer. The cable
requires either a 25-pin male D-type connector or a 9-pin male D­type connector on one end of the cable. Look at the back of the
modem to determine which of these connectors is a match.

The computer end of the cable should also be either a 9-pin or a 25­pin female connector on the other end, depending on your computer.
Check the back of your computer to determine which cable you
need.

Note: Do not purchase a null modem, crossover, or eliminator cable.
Although these cables connect to your serial port, they are designed
to connect a PC to a PC, not to a modem. Your computer dealer
should be able to help you select an appropriate cable.

Note: A cable is included with Macintosh modems because all
Macintosh-based computers use a standard cable.

Voice Modems May Require...

• Stereo-to-stereo cable

If your computer already has speakers connected to a sound card,
you can connect your voice modem and the sound card to use the
same speakers. Refer to “Connecting A Voice Modem to a Sound
Card," later in this guide for more information. You can purchase a
stereo-to-stereo cable at an electronics or computer store.

Introduction 3

• Microphone

We recommend an electret microphone you can plug into the MIC
connector at the back of the modem for use with internal voice
modems. You can purchase a microphone at an electronics or
computer store.

4 Hayes Modem Installation Guide

Installing an Internal
Plug-n-Play Modem

The options for installing a Plug-n-Play modem are:

• Installing a Plug-n-Play modem without Windows 95/98

• Installing a Plug-n-Play modem with Windows 95/98

• Changing the COM Port (Windows 95/98)

• Using DOS Applications with Windows 95/98
Because all systems do not support Plug-n-Play devices, Hayes

products include utilities to configure the modem in non Plug-n-Play
environments. The following pages explain how to install your Plug­n-Play modem with Windows 95/98 and without Windows 95/98.

When installing your new modem, follow the directions below, and
refer to your Windows User’s Guide.

Note: Windows 95/98 users that want to use the modem with DOS
applications, such as interactive games, need to also read the
section, “Using DOS Applications with Windows 95/98.”

Installing an Internal Plug-n-Play Modem 5

Installing a Plug-n-Play Modem
without Windows 95/98

Plug-n-Play modems are designed to be configured for a COM port
by the Windows 95/98 hardware detection program. However, your
Plug-n-Play modem can still be used under Unix, Windows NT 4.0,
Windows 3.11, Windows 3.x, or DOS. There are three ways that a
Plug-n-Play modem can be configured for use in a non-Plug-n-Play
environment:

• Jumper Settings – Changing the jumper setting overrides
the Plug-n-Play capability of the modem. To do so, you need to
remove the jumper from the Plug-n-Play jumper block and place it
over one of the manual jumpers. Please refer to “Possible Jumper
Settings” on page 14 for details on how to configure your modem
using jumper settings.

• Plug-n-Play BIOS - Some computers are designed with a
Plug-n-Play BIOS. A Plug-n-Play BIOS also configures your Plug-n­Play modem for you. With Plug-n-Play BIOS, no additional software,
such as Plug-n-Play manager, is usually required to support Plug-n­Play. Do not load SETCOM16.

• SETCOM16 - If you do not have Plug-n-Play manager or
Plug-n-Play BIOS, you need to use the INSTALL.EXE program
provided on the Driver and Utilities diskette or CD included with your
modem to load SETCOM16.

6 Hayes Modem Installation Guide

Using SETCOM16

Installing the Modem Using SETCOM16:

The following steps outline modem installation using the
INSTALL.EXE program to configure the modem.

1. Before you open your computer to install the modem, unplug it
from the power outlet.

2. Select an empty slot and remove the slot cover plate.

3. Hold the modem by the top and gently slide it into the slot.

4. When you turn on your system, start at the DOS prompt, insert

the Driver and Utilities diskette or CD. Get the A: or D: prompt. Type
INSTALL.EXE. This will install the SETCOM16 program to the hard
drive.

5. Follow the screen instructions to configure your modem for COM
ports 1-4.

Note: If you need to change the configuration of the modem later,
you will need to type: C:\SETCOMM\SETCOM16.EXE. See below
for more detailed information.

Changing the modem configuration using SETCOM16:

Step 1: From the SETCOMM directory on your hard drive,

(usually C:\SETCOMM) type: SETCOM16. Press
Enter.

Step 2: Follow the instructions above to change the

configuration. The AUTOEXEC.BAT file updates
automatically.

Note: If your DOS-based programs are not communicating properly
with the modem, make sure the SETCOM16 utility is configuring the

Installing an Internal Plug-n-Play Modem 7

modem for an IRQ setting supported by your DOS software. Refer to
your DOS software manual for the proper IRQ settings supported by
the software.

To complete your modem installation, refer to Connecting the Phone
Cable.

8 Hayes Modem Installation Guide

Installing a Plug-n-Play Modem
with Windows 95/98

If you are using Windows 95/98, follow the steps below to install a
Plug-n-Play modem.

1. Before you open your computer to install the modem, unplug it
from the power outlet.

2. Select an empty slot and remove the slot cover plate.

3. Hold the modem by the top and gently slide it into the slot.

4. When you turn on your machine and start Windows 95/98, the
New Hardware Found window will display. To install your new
hardware, select Driver from the provided diskette or CD. Press OK.
The Install from Disk window will display.

5. Insert the Driver and Utilities CD or diskette, type D: or A:, and
press OK. Select your modem name and version. Press OK.
Windows 95/98 will install the necessary .INF files onto your hard
drive.

Note: Make sure you select the same modem speed and type as
appears on the modem packaging.

Windows 95/98 configures your new Plug-n-Play modem
automatically. This eliminates the need for you to set COM ports
with jumpers. However, because Windows 95/98 recognizes more
than four COM ports and some software only recognizes four, you
may want to change the Windows 95/98 automatic selection. Also,
in some instances, Windows may mistakenly assign the COM port to
a resource that conflicts with another device. Refer to Changing
Resources in Windows 95/98 for more detailed information.

Installing an Internal Plug-n-Play Modem 9

Changing Resources
in Windows 95/98

In most cases, Windows 95/98 will set up your modem to work
properly. Unfortunately, Plug-n-Play does not always work correctly;
when this occurs, you can usually trace it to a few common
problems.

One problem is your computer has insufficient resources available
to install your modem.

Often the modem gets mistakenly assigned to an I/O range or IRQ
already in use by another device. To change the resources that your
modem is using, do the following:

1. Click on the Start button. Select Settings and choose Control
Panel.

2. Double-click on the System icon and select Device Manager.
Select the Modem tab and highlight the modem to reconfigure.
Press Properties. All the modem properties will be displayed.

3. Select Resources.

4. If the conflicting device list shows a conflict, you need to change
the resources currently assigned to it. If no conflicts show up, then
the problem lies elsewhere.

5. To change the resources, deselect the Use Automatic Settings
indicator box. Try scrolling through the different basic configurations
until you find one that doesn’t report any conflicts. If you can’t find a
basic configuration that does not report a conflict, you’ll need to
manually assign the resources.

10 Hayes Modem Installation Guide

6. To manually assign the resources, select the last Basic
configuration available (typically Basic configuration 0006).

7. If the I/O range reports a conflict double, click on Input/Output
Range. The Edit Input/Output Range dialog box will appear.
Select one of the following values that does not report a conflict:

Value COM Port

03F8-03FF COM 1
02F8-02FF COM 2
O3E8-03EF COM 3
O2E8-02EF COM 4

8. Press OK to accept the value.

9. If the Interrupt Request is reporting a conflict, double-click on
Interrupt Request. The Edit Interrupt Request dialog box should
appear.

10. Scroll through the interrupts until you find one that doesn’t report
a conflict.

11. Press OK to accept the value. Then Press OK to close the
window. A warning window will display to verify that you want to
create a forced configuration. Press Yes.

Note: If you find you don’t have enough resources available, you
may need to disable a COM port. See the “Disabling a COM (Serial)
Port” section on page 19.

12 Hayes Modem Installation Guide

Understanding COM Ports
and IRQ Settings

To successfully install your modem, you need to select a COM port
and IRQ setting that your computer's operating system is not using.

COM Ports

A COM port is a serial setting built into your computer's
motherboard. DOS version 3.3 and higher supports four COM ports.
Windows 95/98 and OS/2 support eight COM ports. COM ports use
IRQ lines to access your computer's processor.

IRQ Settings

An IRQ setting describes an interrupt line that is allocated to a
peripheral device, such as a modem, printer, or sound card. The
address allows the device to interrupt your computer's processor for
attention so that it can perform another function or activity.

Here are some common default COM port and IRQ settings for your
reference.

COM
Port

1 3f8 4
2 2f8 3
3 3e8 4
4 2e8 3

Installing a Non-Plug-n-Play Internal Modem 13

Address Default IRQ

Possible Jumper Settings

To determine the manual settings for your modem, follow the
instructions below, depending on what your modem looks like. Every
modem has a cylindrical on-board speaker (also known as a
squawker) located on it.

If your modem’s on-board speaker is located on the bottom
righthand corner (next to the bracket), you need to remove the
jumper from the JP2 jumper and place it on JP1 for both the COM
port and the IRQ settings.

The example below illustrates specific jumper positions for both the
COM port and the IRQ. At the bottom is a sample of how your
jumper setting may appear after setting both the COM port and the
IRQ.

14 Hayes Modem Installation Guide

If your modem board resembles the one below, with the cylindrical
onboard speaker located in the upper lefthand corner, the
locations of jumper blocks JP1, JP2, JP3, and JP4 should appear
the way they do below.

Disabling a COM (Serial) Port

You can disable your COM ports three different ways:
Through the

CMOS

Through the
mother­board
jumper

Through the
jumper on
the I/O Card

Most of today's newer computer systems allow you to
disable your COM port in the CMOS. Refer to your
computer manual for this procedure.

If your COM port is built into your motherboard, then
move a motherboard jumper to disable the COM port.
Refer to your computer manual for this procedure.

If the COM port is not located directly on your
motherboard, but is on a serial expansion card, then
refer to either your serial card manual or the
computer manual for this procedure.

Using DOS
Applications with
Windows 95/98

With Windows 95/98, when you first try to run a DOS application
that requires your internal modem (such as some interactive
games), your computer may have trouble locating it. When you are
using Windows 95/98 applications, the computer locates the modem
automatically. DOS applications need to be told your modem’s
address.

You can enter a DOS mode three different ways with Windows
95/98. Because the directions vary, please read the steps carefully.

• Shutting down to DOS

• Opening a DOS window

• Using F4 or F8 to open DOS.

24 Hayes Modem Installation Guide

Shutting Down to DOS

You can shut down Windows 95/98 and start DOS to run DOS
applications.

1. From the Start icon, choose Shutdown. Select Restart
Computer in MS-DOS Mode.

2. After restarting, get the A prompt (or B if you are using the B
drive.) Insert the Driver and Utilities diskette or CD and type
INSTALL. This loads the SETCOM16 program.

3. The SETCOM16 EXE program will suggest an address for the
modem. Use the tab to select OK or select Manual to change the
address.

4. SETCOM16 EXE will ask if you want to update the Windows
SYSTEM.INI file. Use the tab key to select None.

Note: Because you are running Windows 95/98, you only want to
update the AUTOEXEC.BAT file. Selecting None will do this
automatically.

5. When you return to DOS, type C:\AUTOEXEC.BAT. Scroll
through the text for a line that looks like the following example:

C:\SETCOMM\SETCOM16.EXE 3E8 5.

6. Copy the line, including the I/O address and IRQ after the .EXE.

7. Type Win at the C:\ prompt to return to Windows 95/98.

8. From the Start icon, select Programs, then Accessories.
Choose Notepad.

the modem you want to use. Press Properties.

3. Select the Resources tab to see the input/output range and
setting display for the modem.

4. Use the displayed information to configure your DOS application.

Note: Because some DOS applications do not support the higher
addresses that Windows 95/98 supports, you may need to “move”
the modem to a different address. Refer to “Changing the COM Port
(Windows 95/98)” to change the address of the modem.

Installing an Internal Modem (Non Plug-n-Play) 27

Using F4 or F8 to Open DOS

When you installed Windows 95/98 initially on your machine, if you
chose to keep your old DOS version, you can press F4 when your
computer is loading Windows 95/98 to stop and return to DOS.
Otherwise, you can press F8 when the “Loading Windows 95/98”
window appears.

1. At the DOS C:\ prompt, get the A:\ prompt (or B is you are using
the B drive.) Insert the Driver and Utilities diskette or CD and type

Connecting a Microphone

We recommend an electret microphone you can plug into the MIC
connector at the back of the modem for use with internal ACCURA
Speakerphone modems. If you want to change the microphone
setting, refer to "Changing the Microphone with ACCURA Internal

Speakerphone Modems."

With external ACCURA Speakerphone modems, you can record
your voice using the handset of your telephone.

With OPTIMA Business modems, you can plug a self-powered
electret microphone into the MICROPHONE connector on the side
of the external models.

For best results, with the least amount of feedback, microphones
should be mounted to the top, front center of your monitor.

Note: If you have a sound card with an internal ACCURA
Speakerphone modem, the microphone must be plugged into the
modem, not the sound card, for the speakerphone to work.

Connecting Voice Modems 39

Changing the Microphone
with ACCURA Internal
Speakerphone
and Message Modems

We recommend that you use an electret microphone with your
internal ACCURA Speakerphone modem. You can also connect a
dynamic microphone (>600 ohms), a self-powered electret
microphone, or a Plantronics (6K) microphone into your modem’s
MIC jack.

We also recommend that you use an electret microphone with your
internal ACCURA Message modem. However, if you want to
connect a dynamic microphone (>600 ohms), a self-powered
electret microphone, or a Plantronics (6K) microphone into this
modem’s MIC jack, you will need to adjust a jumper on your modem.
Follow these steps:

1. Locate the three pins beside the speaker, near the mounting

bracket. The jumper is currently on pins 2 and 3 for an electret
microphone, as shown in the illustration.

2. For a dynamic or self-powered electret microphone, move the

jumper onto pin 1 ONLY. (This is the pin farthest away from the
bracket.)

3. For a Plantronics (6K) microphone, move the jumper onto pins 1

and 2. (These are the two pins farthest away from the bracket.)

40 Hayes Modem Installation Guide

(Illustration shows jumper on pins 2 and 3.)

Note: If you have a sound card with an internal ACCURA
Speakerphone or Message modem, the microphone must be
plugged into the modem, not the sound card, for the speakerphone
to work.

Connecting Voice Modems 41

Connecting a Voice Modem
to a Sound Card

If your computer already has speakers attached to a sound card, you
can connect an internal voice modem and the sound card to use the
same speakers.

With OPTIMA Business modems and ACCURA external models,
you can set the modem and sound card to use the same speakers
through software.

For internal speakerphone modems:

1. Using an 8 inch stereo-to-stereo cable, plug one end into the SPK
connector in the back of the modem.

2. Plug the other end of the stereo-to-stereo cable into the LINE IN
connector on the back of the sound card.

Troubleshooting

COM Port Problems

This section lists some of the most common troubleshooting issues.
When you install an internal modem, you must assign the modem a

unique COM port setting, or with Windows 95/98, you sometimes
must change the COM port automatically selected with Plug-n-Play
modems. If your modem is set to use a COM port that is being used
by another device, you may experience COM port or IRQ conflicts.

Symptoms of COM Port or IRQ Conflict:

• The communications software cannot find the modem.

• Your computer locks up when accessing the modem.

• The modem doesn’t respond to AT commands.

• The modem works in some software applications, but not in others.

• The modem used to work, but doesn’t anymore.

• The serial mouse doesn’t function properly.

Troubleshooting 43

Resolving COM Port or Interrupt Conflicts:

COM port or IRQ conflicts can be resolved by selecting a unique
COM port setting for the modem. If you are a Windows 95 or 98
user, please refer to “Changing Resources
in Windows 95/98” on page 10. If you are a Windows 3.x user, there
are several steps you can follow to prevent COM port conflicts:

1. Identify Serial Ports already being used by your computer. Most
computers using Windows will have a utility to diagnose COM
ports.

Turn your computer off. Remove your modem, and reboot your
system. Exit Windows 3.1, or 3.11.

Type MSD E at the C: prompt. The COM Ports field identifies
how many COM ports your computer has. Type C to identify your
port address. Refer to the following table to identify COM ports.

COM Port Interrupt Base I/0

COM1 IRQ4 03F8
COM2 IRQ3 02F8
COM3 IRQ4 03E8
COM4 IRQ3 02E8

2. If you are using Windows, COM port settings can be found in

the Control Panel. Any changes you make in the Control Panel
must match the jumper settings of the modem and apply to all
Windows communications programs.

For Plug-n-Play modems with Windows 3.1 or 3.11, use
SETCOMM.EXE, or SETCOM16.EXE to set the COM Port.

Once you have selected a configuration in the Control Panel, you
may select the COM port in the communications software without
having to change the IRQ setting because the Control Panel will
change both automatically.

44 Hayes Modem Installation Guide

Troubleshooting 45

Selecting a COM port from the Windows Control
Panel Menu:

Example:

Selecting COM4 from the Windows 3.1 Control Menu:

1. Open Microsoft Windows.

2. Select Main and then Control Panel.

3. Select Ports.

4. Select the COM4 icon.

5. Select Settings.

6. Select Advanced.

7. Change the base I/O Port address from default to 02E8.

8. Change the IRQ setting from default to 3.

9. Select OK and Restart Windows now.

46 Hayes Modem Installation Guide

Selecting a COM port in your Communications
Software Program:

After you have configured the COM port and IRQ setting in the
Control Panel, you must select the same COM port in your
communications software.

Example:

Selecting COM4 in a Communications Software Program:

1. Open your communications software.

2. Locate the COM port settings.

3. Select COM4 or whichever COM port you selected in the
Windows Control Panel.

4. Quit your communications software program.

Troubleshooting 47

General Troubleshooting

If you cannot connect an external modem to your
computer...

Make sure that you are using a modem-to-computer cable. If you
are not sure, contact the store where you bought the modem and
verify that you have the right cable.

If the modem lights are not lit...

If the modem lights are not lit, plug the modem into another outlet
to check the power. If this problem occurs with a previously
working modem, your modem may have been damaged by a
power surge over the electrical or telephone lines.

If the RD and/or SD lights come on or are flashing...

When you’re not online, your modem cable may be damaged.
Turn the modem off, disconnect the modem cable, and turn the
modem back on. If the RD or SD light is still on, you should
contact Customer Service.

If the CD or OH light remains on...

If the CD or OH lights remain on after you have disconnected your
OPTIMA Business modem, contact Customer Service. If you
cannot communicate with the modem, make sure that you have
properly installed your communication software.

48 Hayes Modem Installation Guide

If the modem will not connect over the line to
another modem...

Check your modem and telephone connections, then try dialing
the number on your phone. If you hear a high-pitched whistle, then
another modem is answering the call. If the connections are
secure and the number is correct, the modems may be having
trouble negotiating.

Try a lower speed. Change this in your communications software.

If the modem will not answer an incoming call...

Auto-answer may not be enabled. Refer to your software
instructions to enable auto-answer.

If the modem disconnects unexpectedly...

Try dialing the number again. Also, check for loose connections
between the modem and computer or between the modem and
telephone. If the connections seem secure, you may have had a
bad connection. Try again. Also, you may want to disable Call
Waiting.

Some parameters required for compliance with Telecom’s PTC specifications are dependent upon
the equipment within which this modem is installed. The equipment shall be set to operate within
the following limits for compliance with Telecom specifications.

When the user manually initiates a call via equipment to which the modem card is installed, the
equipment shall operates as follows:

Not more than five call attempts shall be made to the same number within a one hour period.
There shall be at least 60 seconds between call attempts.
Not more than a total of ten call attempts shall be made to the same number for any single manual

call initiation.
Automatic calls to different numbers shall not be less than five seconds apart.
The user must immediately disconnect this modem should it become physically damaged and

arrange for either its disposal or repair.
Only Telepermitted equipment may be connected to the telephone port.
The correct setting for use with this modem in New Zealand are:

provisions outlined below.

It is against the law to copy, reproduce or transmit (including without limitation, electronic
transmission over any network) any part of the program except as provided by the Copyright Act of
the United States (Title 17, United States Code) (the "Laws"). However, you are permitted by Zoom
to write the contents of the program into the machine memory of your computer so that the
program may be executed by a single user. You are also permitted by Zoom to make a back-up
copy of the program subject to the following restrictions:

(1) Each back-up copy must be treated in the same way as the original copy purchased from
Zoom;

(2) If you ever sell or give away the original copy of the program, all back-up copies must also be
sold or given to the same person, or destroyed; and

(3) No copy (original or back-up) may be used while any other copy (original or back-up) is in use.
If you make a back-up copy of the program, you should place the copyright notice that is on the

original copy of the program on every back-up copy of the program. If you ever make any
modification to the program, no copy of the modified version of the program may be transferred
under any circumstances without the written permission of Zoom (See Section 117 of the Copyright
Act).

The above is not an inclusive statement of the restrictions imposed on you under the Laws. For a

Certain programs sold by Zoom are copy-protected (in addition to copyright protected) - that is, the
diskette on which the program is recorded is physically designed so that the program cannot be
copied or reproduced. If the program you have purchased is copy protected and a back-up copy of
the program has been provided to you by Zoom, your rights in the back-up copy are also subject to
the restrictions under the Laws referred to above.
