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.
Jumper Locations
JP4
JP3
JP2
JP1
The jumper diagram above shows the default factory settings for
your fax modem. The jumper JP2 is set for Plug-n-Play mode, which
is used by Windows 95 and 98 computers.
Jumper Function
JP1 Sets the IRQ
JP3, JP4 Set the port address
JP2 Selects either jumpered configuration or Plug-n-Play (default)
To disable the board’s Plug-n-Play feature for Windows 3.1, 3.11,
NT 4.0, and DOS installation, make sure the JP2 jumper is over the
right and center pins.
