Section One - Introduction
The 14.4 Kbps Series FAX/Voice/Data Modem con­nect your computer to all popular high speed modems available today. This manual describes the hardware instal­lation procedures for your new modem product. Additional information on AT commands and S-registers are provided so that your system can be customized for a particular operating environment.
Section Two - Installation
This section will provide step by step instructions on how to install your new 14.4 Kbps FAX/Voice/Data modem. Installation of this modem product is a two-step process consisting of actual hardware installation and communica­tion software installation and configuration.
2.1 Unpacking Your Modem
Before you begin your installation, be certain that you have all the items listed below. This package contains:
• A modem • A telephone cable
• User's manual • Software for the modem
• Software user's manual
2.2 Hardware Installation
Installation of this modem requires opening and ma­nipulating your PC. Exercise caution at all times when working with AC powered and static-sensitive equipment. Turn off and unplug your PC before installation. Discharge any static electricity from your body by touching any metal surface.
1. Turn off and unplug your computer from the AC outlet.
2. Determine how many serial ports are built into your com-
puter (examine the back of your computer). Refer to Figure 2-1 to identify common serial ports.

3. If you have one or more serial ports on the back of your
computer, reconfigure your modem. Your modem is shipped set to COM1 on IRQ4. Reconfigure the modem to either COM3/IRQ5 or COM4/IRQ2 (refer to Table 2-1 in Sec­tion 2.4).
4. Remove your computer's cover
(refer to your computer's owner manual).
5. Select any available half-card
slot, and then remove the slot cover (refer to Figure 2-2).
6. Carefully slide the internal mo-
dem into the slot you have cho­sen, applying even pressure un­til the modem is completely seated in the slot.
7. Fasten the retaining bracket
with the screw from the slot cover. Make sure the modem is properly aligned. Store the slot cover for future use.
8. Replace the computer cover and plug in your computer.
9. Connect the telephone cable from the modem (“LINE”
connector) to the telephone wall jack.
10. Optionally connect: 1) your telephone to the modem's
“PHONE” connector, 2) a speaker to the modem's “SPKR” connector, and 3) a microphone to the modem's “MIC” connector. Note that the distance between the microphone
and the speaker must be greater than twelve (12) inches to prevent unpleasant speaker feedback.
11. Turn your computer on. Your modem is now installed.
2.3 Software Installation/Configuration
You are now ready to install and configure the commu­nication software. Refer to your software manual for instal­lation procedures. Your software must be configured to communicate with the modem on the same COM port and IRQ line used by the modem.
If you are using Microsoft Windows 3.x and have changed the modem's operating setting from the default COM1/ IRQ4 to COM3/IRQ5 or COM4/IRQ2 to avoid a conflict, you must use Windows' Control Panel (in the “Main” Group within Program Manager) to configure Windows to recognize the new settings before installing any software. In Control Panel, double-click on Ports. Click once on the icon for the Com port you have set your modem to. Click the Settings button. Click the Advanced button. The Base I/O Port

Address should already be set by Windows to the COM port address used by the modem (refer to Table 2-1). Change the Interrupt Request Line (IRQ) to match the IRQ on the modem. If you have set the modem to COM4/IRQ2, do not
select IRQ2. You will need to set the IRQ in Control Panel to IRQ9 for Windows to recognize the modem. (In an operating
system designed for 286 or better machines, IRQ 9 is equivalent (redirected) to IRQ2.)
A modem setting which skips one or more COM port assignments requires special attention in the Windows 3.x Control Panel. For example, if your computer is equipped with two serial ports (COM1 and COM2) and have set the modem to COM4 instead of COM3, the Control Panel settings for COM4 may say Default. In this case, Windows
3.x will operate the modem as the third serial device and recognize it as “COM3” (This unusual COM port reassign­ment does not occur in future releases of Windows). The correct COM4 address (2E8) has been placed into the Control Panel COM3 position. Configure the COM3 entry in Control Panel by changing the IRQ box to match the IRQ that has been set on the modem. (When running any Windows
3.x-based communication or fax programs, select COM3 as the COM port for the modem.)
After these settings are made, click OK. Click Restart
Now. Windows can now recognize your modem.
Note: Since the “COM3” substitution for your COM4 modem only occurs under Windows 3.x, your DOS communication and fax programs will still recognize the modem configuration as COM4.
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.
38,400 bps; 8 data bits; no parity; 1 stop bit; RTS/ CTS flow control set to “on;” initialization string: AT&F
The commands used by the modem are compatible with the command set used by Intel modems. Select an “Intel 144I Faxmodem” type in your data communications soft­ware, select a “Generic Class 1” type in your fax software and select “Cirrus Logic” in your Voice software.

2.4 COM Port and Interrupt Settings
If your computer is equipped with one or more serial ports, you will need to change the COM Port setting on the modem (to either COM 3 or 4), or disable the PC's built-in COM port.
An IRQ (interrupt request) is a signal generated by an I/O device that notifies the computer of incoming data. Your internal modem is capable of accessing IRQs 2, 3, 4, and 5.
I/O devices in your computer cannot share an IRQ with another device at the same time. Since IRQs can not be
shared at the same time, COM 3 is generally configured to use IRQ 5, and COM 4 to use IRQ 2. This avoids sharing of IRQs with COM 1 (IRQ4) and COM 2 (IRQ3).
To change the default COM Port or IRQ settings from COM 1/IRQ 4 to another setting, locate the Switch Block on your internal modem (Figure 2-3). Refer to Table 2-1 to configure the Switch Block to the COM Port and IRQ
Table 2-1 Switch Block Settings

combination needed for your application. Any time the
COM or IRQ setting for the modem is changed, the settings in the software must be changed to match.
2.5 Using Fax, Voice, and Speakerphone
Capabilities of the Modem
Your modem has built-in advanced FAX, Voice, and Speakerphone functions. These functions are accessed through software. Please consult your FAX/Voice/Speaker­phone software manual about procedures on using these functions. Note that the modem's FAX/Voice/Speakerphone commands are used by the software to implement these functions and are not designed to be used as standalone AT commands.
Voice functions include recording and playback of voice prompts (files). To record or playback voice with your modem, attach a telephone to the RJ-11 jack marked “PHONE” on the back of the modem. Follow specific instruc­tions in the FAX/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 modem match the software. Type AT on your terminal screen and press ENTER. You may see “AATT” or nothing on the screen. In either case, the modem should respond with an OK or 0. If it does not, please refer to Section 2.4 for information on COM Ports and IRQ’s or 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 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 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
6
provide a user friendly method of accessing the functions you need (i.e. dialing or answering calls).
2.8 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, 38400, and 57600 bps. Make sure your COM port baud rate setting 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.

Setion Four - S Registers
Your modem has 35 registers, designated S0 through S30, S37, S90, S108, and S109. 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 non-volatile 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.
Modem does not respond to commands.
1. Make sure the modem is not configured with a conflicting
COM port and IRQ setting (see Section 2.4). Your modem can not be configured as COM1 (default) if another device in your system is also configured as COM1. Similarly, IRQ settings may not overlap.
2. 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.
3. 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.
4. Make sure the baud rate setting in your software is set to
57600, 38400, 19200, 14400, 9600, 2400, 1200, or 300 bps. An incorrect baud rate prevents the modem from operating properly.
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 2.2 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
16
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. The remote system may be waiting to receive your data before
it begins. Try pressing the ENTER key a few times.
2. Make sure the correct data format (data bits, stop bits, and
parity bits) and flow control (RTS/CTS) method are being used.
3. Make sure the correct terminal emulation mode is being used
(see communication software manual).
4. Make sure the modem is not sharing an IRQ or COM port with
another device (see Section 2.4).
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.
Modem experiences errors while communicating with a remote modem.
1. Make sure the DTE speed is the same as the modem connec-
tion speed when in Direct Mode (\N1 command in effect).
2. Make sure the remote system and your modem use the same
communication parameters (i.e., baud rate, data bit length, parity, and stop bit).
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. Operating at higher speeds under Windows requires a faster CPU (386/486 or better).
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.
17
1. Make sure the correct modem type is selected in the Voice/
FAX software. Use “Cirrus Logic” or similar selection. Do not select “Rockwell or Rockwell ICS” configuration.

Section One - Introduction
The 14.4 Kbps Series FAX/Voice/Data Modem con­nect your computer to all popular high speed modems available today. This manual describes the hardware instal­lation procedures for your new modem product. Additional information on AT commands and S-registers are provided so that your system can be customized for a particular operating environment.
Section Two - Installation
This section will provide step by step instructions on how to install your new 14.4 Kbps FAX/Voice/Data modem. Installation of this modem product is a two-step process consisting of actual hardware installation and communica­tion software installation and configuration.
2.1 Unpacking Your Modem
Before you begin your installation, be certain that you have all the items listed below. This package contains:
• A modem • A telephone cable
• User's manual • Software for the modem
• Software user's manual
2.2 Hardware Installation
Installation of this modem requires opening and ma­nipulating your PC. Exercise caution at all times when working with AC powered and static-sensitive equipment. Turn off and unplug your PC before installation. Discharge any static electricity from your body by touching any metal surface.
1. Turn off and unplug your computer from the AC outlet.
2. Determine how many serial ports are built into your com-
puter (examine the back of your computer). Refer to Figure 2-1 to identify common serial ports.
male connector
Figure 2-1 Common Serial Ports
2
3. If you have one or more serial ports on the back of your
computer, reconfigure your modem. Your modem is shipped set to COM1 on IRQ4. Reconfigure the modem to either COM3/IRQ5 or COM4/IRQ2 (refer to Table 2-1 in Sec­tion 2.4).
4. Remove your computer's cover
(refer to your computer's owner manual).
5. Select any available half-card
slot, and then remove the slot cover (refer to Figure 2-2).
6. Carefully slide the internal mo-
dem into the slot you have cho­sen, applying even pressure un­til the modem is completely seated in the slot.
7. Fasten the retaining bracket
with the screw from the slot cover. Make sure the modem is properly aligned. Store the slot cover for future use.
8. Replace the computer cover and plug in your computer.
9. Connect the telephone cable from the modem (“LINE”
connector) to the telephone wall jack.
10. Optionally connect: 1) your telephone to the modem's
“PHONE” connector, 2) a speaker to the modem's “SPKR” connector, and 3) a microphone to the modem's “MIC” connector. Note that the distance between the microphone
and the speaker must be greater than twelve (12) inches to prevent unpleasant speaker feedback.
11. Turn your computer on. Your modem is now installed.
2.3 Software Installation/Configuration
You are now ready to install and configure the commu­nication software. Refer to your software manual for instal­lation procedures. Your software must be configured to communicate with the modem on the same COM port and IRQ line used by the modem.
If you are using Microsoft Windows 3.x and have changed the modem's operating setting from the default COM1/ IRQ4 to COM3/IRQ5 or COM4/IRQ2 to avoid a conflict, you must use Windows' Control Panel (in the “Main” Group within Program Manager) to configure Windows to recognize the new settings before installing any software. In Control Panel, double-click on Ports. Click once on the icon for the Com port you have set your modem to. Click the Settings button. Click the Advanced button. The Base I/O Port
Figure 2-2 Expansion
Slots
3
Address should already be set by Windows to the COM port address used by the modem (refer to Table 2-1). Change the Interrupt Request Line (IRQ) to match the IRQ on the modem. If you have set the modem to COM4/IRQ2, do not
select IRQ2. You will need to set the IRQ in Control Panel to IRQ9 for Windows to recognize the modem. (In an operating
system designed for 286 or better machines, IRQ 9 is equivalent (redirected) to IRQ2.)
After these settings are made, click OK. Click Restart Now. Windows can now recognize your modem.
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.
38,400 bps; 8 data bits; no parity; 1 stop bit; RTS/ CTS flow control set to “on;” initialization string: AT&F
The commands used by the modem are compatible with the command set used by Intel modems. Select an “Intel 144I Faxmodem” type in your data communications soft­ware, select a “Generic Class 1” type in your fax software and select “Cirrus Logic” in your Voice software.
2.4 COM Port and Interrupt Settings
If your computer is equipped with one or more serial ports, you will need to change the COM Port setting on the modem (to either COM 3 or 4), or disable the PC's built-in COM port.
An IRQ (interrupt request) is a signal generated by an I/O device that notifies the computer of incoming data. Your internal modem is capable of accessing IRQs 2, 3, 4, and 5.
I/O devices in your computer cannot share an IRQ with another device at the same time. Since IRQs can not be
shared at the same time, COM 3 is generally configured to use IRQ 5, and COM 4 to use IRQ 2. This avoids sharing of IRQs with COM 1 (IRQ4) and COM 2 (IRQ3).
To change the default COM Port or IRQ settings from COM 1/IRQ 4 to another setting, locate the Switch Block on your internal modem (Figure 2-3). Refer to Table 2-1 to configure the Switch Block to the COM Port and IRQ combination needed for your application. Any time the
4
COM or IRQ setting for the modem is changed, the settings in the software must be changed to match.
2.5 Using Fax, Voice, and Speakerphone
Capabilities of the Modem
Your modem has built-in advanced FAX, Voice, and Speakerphone functions. These functions are accessed through software. Please consult your FAX/Voice/Speaker­phone software manual about procedures on using these functions. Note that the modem's FAX/Voice/Speakerphone commands are used by the software to implement these functions and are not designed to be used as standalone AT commands.
Voice functions include recording and playback of voice prompts (files). To record or playback voice with your modem, attach a telephone to the RJ-11 jack marked

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 modem match the software. Type AT on your terminal screen and press ENTER. You may see “AATT” or nothing on the screen. In either case, the modem should respond with an OK or 0. If it does not, please refer to Section 2.4 for information on COM Ports and IRQ’s or 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 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 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 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, 38400, and 57600 bps. Make sure your COM port baud rate setting 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.
3.3 Basic AT Commands

Setion Four - S Registers
Your modem has 35 registers, designated S0 through S30, S37, S90, S108, and S109. 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 non-volatile 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.
Modem does not respond to commands.
1. Make sure the modem is not configured with a conflicting
COM port and IRQ setting (see Section 2.4). Your modem can not be configured as COM1 (default) if another device in your system is also configured as COM1. Similarly, IRQ settings may not overlap.
2. 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.
15
Similarly, IRQ settings must be set correctly to receive data from the modem.
3. 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.
4. Make sure the baud rate setting in your software is set to
57600, 38400, 19200, 14400, 9600, 2400, 1200, or 300 bps. An incorrect baud rate prevents the modem from operating properly.
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 2.2 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. The remote system may be waiting to receive your data before
it begins. Try pressing the ENTER key a few times.
2. Make sure the correct data format (data bits, stop bits, and
parity bits) and flow control (RTS/CTS) method are being used.
3. Make sure the correct terminal emulation mode is being used
(see communication software manual).
4. Make sure the modem is not sharing an IRQ or COM port with
another device (see Section 2.4).
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 connec-
tion speed when in Direct Mode (\N1 command in effect).
2. Make sure the remote system and your modem use the same
communication parameters (i.e., baud rate, data bit length, parity, and stop bit).
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. Operating at higher speeds under Windows requires a faster CPU (386/486 or better).
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/

9.3 DOC Compliance Information
NOTICE: The Canadian Department of Communications label
identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational and safety requirements. The Department does not guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an accept­able method of connection. The customer should be aware that compliance with the above conditions may not prevent degrada­tion of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications com­pany cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.
Caution: Users should not attempt to make such connections
19
themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.
NOTICE: The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device, to prevent overload­ing. The termination on a loop may consist of any combination of devices subject only to the requirement that the sum of the Load Numbers of all the devices does not exceed 100.
