Installation of this modem requires familiarity

5
with your computer's serial port. This is usually a
25-pin or 9-pin male connector on the back of your
computer, but computer equipment varies. Consult
the computer's manual on this topic. You will also
need a properly configured serial cable. The
recommended cable for IBM Compatible PCs with a
9-pins serial port is an RS-232 cable with all 9-pins
configured straight-through. For computers with a
25-pin serial port, use an IBM AT type (25-pins to
9-pins) RS-232 serial cable. For Macintosh Plus or
newer computers, use only a high speed RS-232
serial cable that supports hardware flow control
signals.
Note: Exercise caution when working with
any AC-powered device. Always turn the
power off when connecting or
disconnecting cables to or from the device.
1. Turn your computer off.
2. Plug the male end of the RS-232 modem cable
into the connector marked RS-232C on the back
of the modem (refer to Figure 2-2).

2.4 Hardware Configuration (Plug and Play)
Your modem is configured using the Plug and
Play (PnP) capabilities of your computer. Plug and
Play is a set of specifications that define the ability
for the computer hardware and operating system to
automatically configure all compliant devices that
are installed, relieving the user of the need to
determine which addresses and interrupts to use
for each device. Consult your PC's owner's manual
to determine if it is PnP Revision 1.0a compliant.
You most likely have a Plug and Play Revision 1.0a

8
compliant system if it was purchased after June
1994 or if the BIOS is dated after June 1994.
Proceed to one of the following sections,
depending on your system's configuration:
•Section 2.4.1 if you are running Windows
95 (with or without a Plug and Play PC)
•Section 2.4.2 if you are running Windows
3.1x or DOS on a PnP-compliant PC.
•Section 2.4.3 if you are running DOS or
Windows 3.1x on a non-PnP PC.
2.4.1 Configuring in Windows 95
The version of Windows 95 you have will
determine which set of dialog boxes is presented to
you when installing the modem in Windows 95.
Proceed to one of the following sections, depending
on your Windows 95's diaglog box:
•Section 2.4.1.1 when Windows 95 starts for
the first time after card installation, it detects
the modem and it displays the New
Hardware Found dialog box
•Section 2.4.1.2 when Windows 95 starts for
the first time after card installation, it detects
the modem and it displays the Update
Device Driver Wizard.
2.4.1.1 Windows 95 Release 4.00.950

into the drive selected, and then click OK. "Insert

9
the modem's driver diskette into the disk drive and
type A:\ (or B:\ if inserted in drive B) in the "Copy
manufacturer's files from:"box. Click "OK."
Windows 95 may request its own installation
disks or CD-ROM for some files. Insert the
Windows 95 disks or CD-ROM as required. When
all necessary files are copied, the modem is
configured. Windows 95 will assign the modem a
COM port and IRQ line. Proceed to Section 2.5.
2.4.1.2 Windows 95 Release 4.00.950 B
When Windows 95 starts for the first time after
card installation, it detects the modem and displays
the Update Device Driver Wizard.
Insert the driver disk into the disk drive and click
"Next." Windows will find the driver on the driver
disk. Click "Finish." Windows 95 may request its
own installation disks or CD for some files. Insert
the Windows 95 disks or CD as required.
Windows will now find a second device on the
modem. Make sure that the driver disk is still in the
disk drive and click "Next." Windows will find the
second driver. Click "Finish" to complete the
installation.
When all necessary files are copied, the modem
is configured. Windows 95 will assign the modem a
COM port and IRQ line. Proceed to Section 2.5.
2.4.2 Configuring in a Plug and Play System
without Windows 95
When this modem is installed in a Plug and Play
system without Windows 95, the computer's BIOS
will assign a COM port and IRQ line to the modem.
Proceed to Section 2.5, Software
Installation/Configuration.
2.4.3 Configuring in a Non-Plug and Play

10
System
Computers without native Plug and Play
capabilities require the use of the included modem
driver. If you have not already installed this driver,
refer to the file README.1ST on the Windows 95
driver disk for installation and configuration
instructions. Once the driver is installed the modem
is enabled and configured during system boot-up.

Note: Any time the COM or IRQ setting for the
modem is changed, the settings in the software
must be changed to match.
2.5 Software Installation and Configuration
You are now ready to install and configure the
communication software. Refer to your software
manual for installation procedures.
We suggest the following communication
parameters when you first use your data
communication software. Consult the software
manual for information on using these and other
parameters/features.
115,200bps; 8 data bits; no parity; 1 stop bit;
RTS/CTS flow control set to "On;"
initialization string: AT&F
We suggest that a "Generic Class 1" modem
type should be selected in your fax software, and a
Generic Rockwell
selected in your Voice software.
Note that your software must be configured
to communicate with the modem on the
same COM port and IRQ line used by the
modem.
2.6 Using the Fax, Voice, and

13
(Speakerphone) Capabilities of the
Modem
Your modem has built-in advanced FAX, Voice,
and Full Duplex (Speakerphone) functions. Please
consult your FAX/Voice/(Speakerphone) software
manual about procedures on using these features.
Voice functions include recording and playback
of voice prompts (files). You may record or
playback voice with your modem by attaching a
telephone to the RJ-11 jack marked "PHONE" or by
attaching a microphone to the the back of the
modem bracket. Follow instructions in the
FAX/Voice/(Speakerphone) software on recording
and playback of voice prompts.
2.7 Testing Your Modem After Installation
In order to test your modem you should be
familiar with your communication software. Load
and set up your communication software and enter
into "terminal mode." Make sure that the COM Port
and IRQ settings of the modem match the software.
Type AT on your terminal screen and press
ENTER. You may see "AT" , "AATT" or nothing on
the screen. In any case, the modem should
respond with an OK or 0. If it does not, either the
modem may not have been installed properly or the
software has not been properly configured. Review
Sections 2.2-2.5 and be certain that the modem
and the software have been properly installed. If
required, refer to Section 6 for additional
troubleshooting information.
2.8 Using Your Modem
The communication software included with your
modem product provides a user friendly interface to
access the fax, voice and data functions of your
modem. This software should be sufficient for
all of your communication needs. There may be
times when you need to access the modem

14
manually via modem commands. Read Section 3
for a summary description of the modem command
set before manually accessing the modem. You
may want to read the software manual first,
however, as the software may already provide a
user friendly method of accessing the functions you
need (i.e. dialing or answering calls).
2.9 Where To Go From Here
You should familiarize yourself with the functions
available from the included software by reading its
manual. You will be accessing most, if not all, of the
modem's functions from this software. You may
also use any other commercially available
communication software with the modem. Read
Section 3 only if you are interested in accessing the
modem manually, and not through the included
software. Section 4 and 5 contain reference
material, and can be skipped. If you have difficulties
getting your modem to work, read Section 6 -
Troubleshooting to find answers to commonly
asked questions and problems.
Section Three - AT Command Set
3.1 Executing Commands
Commands are accepted by the modem while it
is in Command Mode. Your modem is automatically
in Command Mode until you dial a number and
establish aconnection. Commands may be sent to
your modem from a PC running communication
software or any other terminal devices.
Your modem is capable of data communication
at rates of: 300, 1200, 2400, 4800, 9600, 14400,
19200, 28800, 38400, 57600, and 115200 bps.
Make sure your COM port baud rate settings in your
communications software is set to one of the above
speeds.

3.2 Command Structure
All commands sent to the modem must begin
with AT and end with ENTER. All commands may
be typed in either upper or lower case, but not
mixed. To make the command line more readable,
spaces may be inserted between commands. If you
omit a parameter from a command that requires
one, it is just like specifying a parameter of 0.
Example:ATH [ENTER]
This command causes your modem to hang up.
