connector on the back of your computer. 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 25-pin serial port is an RS232 cable with all 25 pins configured Straight-through.
1
For computers with a 9-pin serial port, use an IBM AT type
(9-pin to 25-pin) 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 ACpowered 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

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. Proceed to Section
2.4.
2.3.2
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 installa3
tion 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. Proceed to Section 2.4.
2.4 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.
115,200 bps; 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” modem type should be selected in your Voice
software.
Note that the COM port setting in your communication software must be the COM port that
connects the modem to the computer.
2.5 Using the Fax, Voice, and 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
MIC jack and a speaker to the SPK jack located on the back
of the modem bracket. Follow instructions in the FAX/
4
Voice/Speakerphone software on recording and playback of voice prompts.
2.6 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
software match the modem. 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, please refer to
Section 6 for troubleshooting information.
2.7 Using Your Modem
The communication software included with your
modem product provides a user friendly interface to
access the voice and fax 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 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).
2.8 Front Panel LEDs
The modem provides LED indicators on the front panel
to allow call progress monitoring. When the LEDs are lit
they indicate the following:
TST
HS
AA
CD
OH
RD
Flashing when the modem is in the test mode
or if an error is detected.
High speed -on when communicating at 2400
bps or above.
Auto-Answer On when auto answeris
enabled. Flash when ring is detected.

preparation to dialing or answering a call
Receive Data Data is being sent to the
5
SD
TR
MR
computer from the modem
Send Data Data is being received by the
modem from the computer
Terminal Ready The modem is able to receive
commands.
Modem Ready The modem is turned on.
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 a
connection. 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
6
command that requires one, it is just like specifying a
parameter of 0. Example:
ATH [ENTER]
This command causes your modem to hang up.
3.3 Basic AT Commands

Section Four - S Registers
Your modem has 41 registers, designated S0 through
S95. Table 4-1 shows the registers, their functions, and
their default values. Some registers can have their values
changed by commands. If you use a command to change
a register value, the command remains in effect until you
turn off or reset your modem. Your modem then reverts
to the operating characteristics specified in its nonvolatile memory. Refer to Section 3 for information on how
to use the AT commands to manipulate the S registers.

Section Six - Troubleshooting
This section describes some of the common problems you may encounter while using your modem. If you
can not resolve your difficulty after reading this chapter,
contact your dealer or vendor for assistance.
15
Modem does not respond to commands.
1. Make sure the communication software is configured
to "talk" to the modem on the correct COM port and IRQ
setting (same COM port and IRQ setting as the
modem). Your communication software must know
which address your modem is using in the system in
order to pass data to it. Similarly, IRQ settings must be
set correctly to receive data from the modem.
2. Make sure that your modem is initialized correctly.
Your modem may have been initialized to not display
responses. You may factory-reset the modem by
issuing AT&F and press ENTER. The factory default
allows the modem to display responses after a
command has been executed.
Modem does not dial.
1. Make sure the modem is connected to a working
phone line. Replace the modem with a working phone
to ensure that the phone line is working.
2. Make sure the phone line is connected to the jack
marked "LINE" Incorrect connection prevents the
modem from operating properly. Refer to Section 2.3
for modem connection instructions.
Modem dials but does not connect.
1. Make sure the IRQ setting is identical on both the
modem and the software. Modem and software must
be configured identically.
2. Make sure the phone line is working properly. Replace
the modem with a regular phone and dial the number.
If the line sounds noisy, you may have difficulty
connecting to the remote device.
Modem makes a connection but no data
appears on your screen.
1. Make sure the correct data format (data bits, stop bits,
and parity bits) and flow control (RTS/CTS) are being
used.
2. Make sure the correct terminal emulation mode is
being used (see communication software manual).
High pitch tone is heard whenever you answer
the phone.
1. Make sure Auto-Answer is turned off. Your modem
is factory configured to NOT auto-answer. Issue
AT&F to factory reset your modem.
16
Modem experiences errors while
communicating with a remote modem.
1. Make sure the DTE speed is the same as the modem
connection speed when in Direct Mode.
2. Make sure the remote system and your modem use the
same communication parameters (speed, parity, etc.).
3. Make sure RTS/CTS hardware flow control is enabled
and XON/XOFF software flow control is disabled in
the communication software.
4. Make sure the data speed is not faster than your
computer's capability. Most IBM compatibles are capable of 19,200 bps under DOS and Windows 3.X.
Operating at higher speeds under Windows requires
a 486 or faster CPU or Windows 95.
Modem experiences bursts of errors or
suddenly disconnects while communicating
with a remote modem.
1. Make sure Call Waiting is turned off.
2. Make sure the phone line does not exhibit excess
noise.
Modem exhibits poor voice record or
playback.
1. Make sure the correct modem type is selected in the
Voice/FAX software. Use “Generic Rockwell” or
similar selection.
