to the following instructions.

MT9234ZPX-UPCI

1. Turn off your system and unplug it. Failure to do so may result in damage to both the MultiModem
and your system. Do not turn on the system until the instructions tell you to do so.

2. Remove the cover from your system as instructed in the system manual.

3. If you are installing a MT9234ZPX-PCIE board in a low profile machine, you will need to change the
mounting bracket to the low profile mounting bracket.

4. Select an empty PCI expansion slot. Remove the expansion slot cover and save the retaining screw.

Chapter 2 - Installation

5. Before handling the MultiModem, discharge static in your body by touching a piece of bare metal on
the chassis. Carefully remove the MultiModem from its antistatic bag, handling it only by the
mounting bracket and edges. Do not touch the gold-plated connectors along the bottom edge.

6. Look at the system’s main board to determine either PCI or Express connector. Place the
MultiModem directly above the expansion slot and gently, but firmly, push it into the connector until
the card’s retaining bracket is flush against the system chassis.

8. Fasten the retaining bracket to the system chassis with the screw saved in step 4.

9. Replace the system cover.

Make the External Connections

Now connect the MultiModem to the telephone line and, optionally, to your telephone. For voice mail or
speakerphone use, you can also connect it to a microphone and an external speaker, headphone, or sound
card. The microphone can be used for recording answering machine messages or for speakerphone use.
The speaker or headphone can be used for playing back messages or as a speakerphone.

Line Connection

Plug one end of the provided telephone cable into the modem’s LINE jack, and the other end into a
telephone wall jack. This is the only required connection.

Note: The LINE jack is not interchangeable with the PHONE jack. Do not plug the phone into the LINE jack

or the line cable into the PHONE jack.

Note: The Federal Communications Commission (F CC) and Industry Canada impose certain restrictions on

equipment connected to public telephone systems.

Phone Connection (Optional)

If you wish to connect a telephone to the same line as the modem, plug it into the modem’s PHONE jack.

Note: The PHONE jack is not interchangeable with the LINE jack. Do not plug the phone into the LINE jack

or the line cable into the PHONE jack.

Microphone/Headphone Connection (Optional)

For voice mail or speakerphone applications, plug an unamplified microphone into the MIC jack. The
microphone and headphone should have a stereo 3.58mm (9/64-inch) mini plug. Do not use a monophonic
microphone.

Sound Card and Speaker Connections (If you have the Voice Option)

For voice mail or speakerphone applications, use a 3.58mm (9/64-inch) plug male-to-male stereo patch cord
to connect the LINE OUT jack on the modem to the LINE IN jack on your sound card. If your sound card
does not have a LINE IN jack, use its MIC jack.

This will allow you to hear modem activity whether it is originating or answering a call, or playing a recorded
message. If you do not have a sound card, you can plug an amplified speaker into the LINE OUT jack.

Chapter 3 – Remote Configuration

Chapter 3: Remote Configuration

Remote configuration is a network management tool that allows you to configure the MultiModem anywhere
in your network from one location. With password-protected remote configuration, you can issue AT
commands to a remote modem for maintenance or troubleshooting as if you were on site.

Basic Procedure

The following steps are valid regardless of whether the connection is established by the local or the re mote
Multi-Tech modem.

Note: For this procedure, the remote computer must be running, and a communication p rogram must be

ready for a data connection.

1. Establish a data connection with a remote MultiModem.

2. Send three remote configuration escape characters followed by AT and the setup password, and

press E
correct password before being disconnected. If the password is correct, the remote modem responds
with OK.

3. Type AT commands to configure the remote modem.

4. When you have finished configuring the remote modem, save the new configuration by typing

AT&W0 and pressing E

NTER. Example: %%%ATMTSMODEM (all capital letters). You have four tries to enter the

NTER.

5. Type ATO and press E

Setup

Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who
has the User Guide knows the default setup password, you should change the password and possibly
also the remote configuration escape character. Record your changes for future use.

To Change the Setup Password

1. Open a data communications program such as HyperTerminal.

2. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and
then press E
characters long. The modem responds with OK.

CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the

same case as you set it up.

3. The new password is saved automatically. You can now either enter more AT commands or exit
the data communications program. The next time you wish to set up the modem, you must use
the new password.

NTER. The password can include any keyboard character, and can be up to eight

Chapter 3 - Remote Configuration

To Change the Remote Escape Character

To further improve security, you can change a remote modem’s remote configuration escape character
either locally or remotely. The remote configuration escape character is stored in register S9. The factory
default is 37, which is the ASCII code for the percent character (%). Setting S9 to 0 (zero) disables
remote configuration entirely.

CAUTION: If you set S9 to 0 (zero) remotely, you won’t be able to change it back remotely.

1. Establish a remote configuration link with the remote modem as described in “Basic Procedure.”

2. Type ATS9=n, where n is the ASCII code for the new remote configuration escape character,
and then press E

NTER.

3. Save the new value by typing AT&W and pressing E

4. Type ATO and press E

NTER to exit remote configuration.

Chapter 4 - Troubleshooting

Chapter 4: Troubleshooting

Your modem was thoroughly tested at the factory before it was shipped. If you are unable to make a
successful connection, or if you experience data loss or garbled characters during your connection, it is
possible that the modem is defective. However, it is more likely that the source of your problem lies
elsewhere. The following symptoms are typical of problems you might encounter:

• The modem does not respond to commands.

• The modem cannot connect when dialing.

• The modem disconnects while online.

• The modem cannot connect when answering.

• File transfer is slower than it should be.

• Data is being lost.

• There are garbage characters on the monitor.

• The modem doesn’t work with Caller ID.

• Fax and data software can’t run at the same time.

• The voice functions don’t work.

The Modem Does Not Respond to Commands

• Make sure you are issuing the modem commands from data communications software, either

manually in terminal mode or automatically by configuring the software. (You cannot send
commands to the modem from the DOS prompt.)

• Make sure you are in terminal mode in your data communications program, then type E1 and press

NTER. If you get an OK response from your modem, your connections are good and the problem

E
likely is in the connection setup in your communications software.

• If you don’t get an OK, make sure you have properly configured the port in your communications

program. Most legacy (prior to Windows 95) communications programs connect to the COM port
when the software loads and remain connected until the program terminates. Some programs ca n
disconnect without exiting the program. If this is the case, try issuing the software’s connection
command. If more than one communications program is open, they may conflict with each other.
Make sure all other communications programs are closed, and then try to make the connection
again.

• Your communication software settings might not match the port the modem is connected to.

Make sure the COM port you chose during setup matches the COM port set in your communications
software. See Chapter 2 for more information.

Another expansion card, such as a sound or game card, might be using the same COM port,
memory address, or interrupt request (IRQ) as your modem. See Chapter 2 for information on
verifying the configuration for your operating system. Look for conflicts with other devices installed on
your computer. Resources are assigned at power-up by the computer’s BIOS. If the resources
assigned to the MultiModem conflict with the resources of another device, the resources of the
second device have to be changed. Select the port the conflicting device is on and change it to
resolve the conflict. If you need to change switches or jumpers on the conflicting device, refer to the
device’s documentation.

• If you have another MultiModem, install it and try to make a connection.

• The modem might have a problem beyond the scope of this user guide. If you have another Multi-

Tech modem, try swapping modems. If the problem goes away, call Technical Support for
assistance.

Multi-Tech Systems, Inc. MT9234ZPX User Guide 21

Chapter 4 - Troubleshooting

The Modem Cannot Connect When Dialing

Reasons why the MultiModem may fail to connect include:

• lack of a physical connection to the telephone line.

• a wrong dial tone.

• a busy signal.

• a wrong number.

• no modem at the other end.

• a faulty modem, computer, or software at the other end.

• incompatibility between modems

• poor line conditions.

You can narrow the list of possibilities by using extended result codes. Extended result codes are
enabled by default. If they have been disabled, include V1X4 in the modem’s initialization string, or in
terminal mode enter ATV1X4 and press E
progress.

• If the modem reports NO DIALTONE, check that the modem’s telephone line cable is connected to

both the modem’s LINE jack (not the PHONE jack) and the telephone wall jack. If the cable looks
secure, try replacing it.

If that doesn’t work, the problem might be in your building’s telephone installation. To test the
building installation, check for a dial tone by connecting a standard telephone set to the line in place
of the modem. If you hear a dial tone, your modem might be installed behind a corporate phone
system (PBX) with an internal dial tone that sounds different from the normal dial tone. In that case,
the modem might not recognize the dial tone and might treat it as an error. Check with your PBX
personnel or the PBX system manual to see if you can change the internal dial tone. If you can’t,
change your modem’s initialization string to replace X4 with X3, which will cause the modem to
ignore dial tones (note, however, that X3 is not allowed in some countries, such as France and
Spain).

NTER. When you dial again, the modem reports the call’s

• If the modem reports BUSY, the other number might be busy. Try again later. BUSY can also

indicate that you failed to add a 9, prefix to the phone number if you must dial 9 for an outside line.
If you must dial 9 to get an outside line, the easiest way to dial it automatically using legacy software

is to include it in the modem’s dial prefix, e.g., ATDT9,. Note the comma, which inserts a pause
before the number is dialed. By inserting 9, into the dial prefix, you do not have to include it in each
directory entry.

To change the dial prefix in Windows HyperTerminal, select Connect from the Call menu, click
Dialing Properties, and type 9 in the local and long distance boxes.

• If the modem reports NO ANSWER, the other system has failed to go off-hook, or you might have

dialed a wrong number. Check the number.

• If the modem reports NO CARRIER, the phone was answered at the other end, but no connection

was made. You might have dialed a wrong number, and a person answered in stead of a computer,
or you might have dialed the correct number but the other computer or software was turned off or
faulty. Check the number and try again, or try calling another system to make sure your modem is
working. Also, try calling the number on your telephone. If you hear harsh sounds, then there is a
modem at the other end. In that case, the modems might be having problems negotiating because of
incompatibilities or line noise. Try the call again, connecting at a lower speed by setting register S37
to a lower rate (for example, by typing ATS37=11 in the terminal window and pressing E

NTER).

• Poor line conditions can also affect the connection. When using V.34 or V.32 client-to-client

connections in poor conditions, setting S38=0 may result in better performance.

Chapter 4 - Troubleshooting

The Modem Disconnects While Online

• If you have Call Waiting on the same phone line as your modem, it can interrupt your connection

when someone tries to call you. If you have Call Waiting, disable it before each call. In most
telephone areas in North America, you can disable Call Waiting by preceding the telephone number
with *70 (but first check with your local telephone company).

You can automatically disable Call Waiting by including the disabling code in the modem’s dial prefix
(e.g., ATDT*70,—note the comma, which inserts a pause before the number is dialed). For example,
in Windows select Start | Settings | Control Panel, and then Modems. In the Modems Properties
dialog box, select Multi-Tech MT9234ZPX-UPCI, and then click Dialing Properties. Check This
location has call waiting, and then select the correct code for your phone service.

• If you have extension phones on the same line as your modem, you or someone else can interrupt

the connection by picking up another phone. If this is a frequent problem, disconnect the extension
phones before using the modem, or install another phone line especially for the modem.

• Check that the phone cord between the modem’s LINE jack and the wall jack is undamaged and

firmly connected to both.

• You might have had a poor connection because of line conditions or the problem might have

originated on the other end of the line. Try again.

• Your ISP might have hung up on you because of lack of activity on your part or because you

exceeded your time limit for the day. Try again.

The Modem Cannot Connect When Answering

• Autoanswer might be disabled. Turn on autoanswer in your communications program or send the

command ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.

• The application should supply DTR. The default DTR Control command (&D2) inhibits autoanswer.

To enable autoanswer, change DTR Control to &D0, and make sure &Q0, &Q5, or &Q6 is also set.
For more information, see the &D command in the AT Commands Reference Guide.

File Transfer Is Slower Than It Should Be

• If you are using a slow transfer protocol, such as Xmodem, try Zmodem or Ymodem/G instead.

• Is your line noisy? If there is static on your line, the modem has to resend many blocks of data to

ensure accuracy. You must have a clean line for maximum speed.

• If you are downloading a compressed file with MNP 5 hardware compression enabled, try disabling

data compression. The transfer may be marginally slower with data compression enabled, because
hardware data compression cannot compress a file already compressed by an archiving program.

• Does your Internet service provider (ISP) use the same 56K protocol as your modem? The default

setting of your modem is to connect using either the V.92 or the V.90 protocol, depending on which
one the ISP’s modem is using. If your ISP uses the V.90 protocol, the maximum speed you will be
able to upload at is 33,600 bps. Check with your ISP to see which protocols it supports.

• Are you trying to send a file to another client modem? If so, then your maximum possible connect

speed is 33,600. You can upload at speeds greater than 33,600 bps only when connected to an ISP
that supports the V.92 protocol.

• Try entering the I11 command in command mode after disconnecting and before a reset to display

information about the last connection, making a screen print of the connection statistics, and
checking for parameters that might be unacceptable.

Multi-Tech Systems, Inc. MT9234ZPX User Guide 23

Chapter 4 - Troubleshooting

Data Is Being Lost

• If you are using data compression, set the serial port baud rate to two to six times faster than the

data rate.

• Make sure the flow control method you selected in your software matches the method selecte d in the

modem (see AT commands &K and \Q.)

• Enter the I11 command in command mode and before the modem is reset to display information

about the last connection. Then make a screen print of the connection statistics, and look for
unacceptable parameters. To display information about the present configuration, you must use the
escape sequence, +++, to ensure command mode while still on line. To return to on line mode, set
ATO.

There Are Garbage Characters on the Monitor

• Your computer and the remote computer might be set to different word lengths, stop bits, or parities.

If you have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your communication
software.

• You might be experiencing line noise. Enable error correction, if it is disabled, or hang up and call

again; you might get a better connection the second time.

• At speeds above 2400 bps, the remote modem might not use the same transmission or error

correction standards as your modem. Try connecting at a slower speed or disabling error correction.
(With no error correction, however, line noise can cause garbage characters.).

• Enter the I11 command in command mode and before the modem is reset to display information

about the last connection. Then make a screen print of the connection statistics, and look for
unacceptable parameters. To display information about the present configuration, you must use the
escape sequence, +++, to ensure command mode while still on line. To return to on line mode, set
ATO.

The Modem Doesn’t Work with Caller ID

• Caller ID information is transmitted between the first and second rings, so if autoanswer is turned off

(S0=0) or if the modem is set to answer after only one ring (S0=1), the modem will not receive Caller
ID information. Check your initialization string, and if necessary change it to set the modem to
answer after the second ring (S0=2).

• Make sure that you have Caller ID service from your telephone company.

Fax and Data Software Can’t Run at the Same Time

• Communication devices can be accessed by only one application at a time. In Windows 2000 and

higher, you can have data and fax communication applications open at the same time, but they
cannot use the same modem at the same time.

The Voice Functions Don’t Work

There are several tests that you can perform to verify the voice circuits of the MultiModem. First, make
sure all connecting cables—telephone, microphone, and speaker—are u ndamaged and firmly connected
to the correct jacks. Then retry whatever action was not working. If the problem persists, try the voice
mail test; if that doesn’t work, and if you have a microphone and speaker connected to the MultiModem,
try the loopback and speakerphone tests, which do not require special software.

Voice Mail Test

Test the MultiModem’s voice function set up the MultiModem for voice mail. Have an acquaintance call
and leave a message, and then play it back.

If your modem does not play sound files in voice mode, go to Windows Control Panel and double-click
the Multimodem icon. Under the Audio tab, select Modem Wave Driver as your preferred device for
both playback and recording, then try again.

Loopback Test

1. Connect a microphone and speaker to the MultiModem. To avoid feedback, make sure the

microphone and speaker are well separated; better yet, use a headphone instea d of a speaker.

2. Select Start, point to Programs, point to Accessories, and click HyperTerminal.

3. Click Cancel in the Connection Description dialog box.

Appendix C – Upgrading your Modem

Appendix C – Upgrading Your Modem

Introduction

Your modem is controlled by semi-permanent software, called firmware, which is stored in flash
memory. Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off.
However, it can be changed by either the manufacturer or the user as bugs are fixed or new features are
added. Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few
minutes by using the following procedures.

Upgrade Overview

The upgrade procedure consists of the following steps, which are described in greater detail in the

following sections.

1. Identify the model number and firmware version of your modem.

2. Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has the
current firmware, there is no need to upgrade it.

3. Download the upgrade file and the appropriate Flash Wizard for your modem.

4. Install the Flash Wizard and extract the firmware .HEX file from the file you downloaded.

5. Document and clear your stored parameters.

6. Upgrade the modem’s firmware using the .HEX file and the Flash Wizard.

7. Restore your parameters.

Step 1: Identify the Modem Firmware

You must know the model number and firmware version of your Multi-Tech modem to know whether or not
you should upgrade it.

1. Run your favorite terminal program. If you are using Windows 2000 or above, you can use
HyperTerminal.

2. In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on your
screen, be sure to type it completely, and then press E
OK, repeat the AT&F command.

3. Now type ATI, press E
should appear similar to that shown below. In the example below, the firmware version is 1.02d.

Step 2: Identify the Current Firmware Version

Identify the current version of your modem’s firmware at the Multi-Tech Web site. If your modem already
has the current firmware, there is no need to upgrade it.

1. Using your favorite Web browser, go to

http://www.multitech.com/SUPPORT/MultiModem/firmware.asp.

2. Scroll down to your modem model number.

3. Look at the firmware version number for your modem.

4. If the firmware version number matches the firmware version number found in “Step 1: Identify the
Modem Firmware,” your modem has the current firmware version, and does not need to be upgrade.

Multi-Tech Systems, Inc. MT9234ZPX User Guide 33

Appendix C – Upgrading Your Modem

5. If the firmware version number is greater than the firmware version number found in “Step 1: Identify
the Modem Firmware,” your modem has an older firmware version. Continue with “Step 3: Downlo ad
the Upgrade File.”

Warning: The first digit of the new firmware must match the first digit of the old firmware, or the

modem may not work properly. E.g., if your current firmware version is 4.16, replace it only with

4.xx firmware, not 6.xx firmware.

Step 3: Download the Upgrade File

1. If you are not already at the MultiModem Firmware page of the Multi-Tech Web site, follow the
procedure in “Step 2: Identify the Current Firmware.”

2. Download the upgrade file for your modem by clicking its name, and save the file in a temporary
folder on your hard disk.

3. In the same section of the Web page, download the Flash Wizard utility by clicking it, and save it in
the same folder. Alternately, install the Flash wizard from the MultiModem compact disc.

Step 4: Extract the Upgrade Files

1. Install the Flash Wizard utility by double-clicking the Flash Wizard file name in Windows Explorer.

2. Extract the upgrade files by double-clicking the file name. The extracted files include a .HEX file,
which contains the upgrade data, and a Readme file.

3. Copy the upgrade .HEX file into the Flash Wizard folder, which, in a default installation, is at
C:\Program Files\MultiTech Systems\Flash Wizard\.

Step 5: Document and Clear Your Stored Paramenters

Before you flash your modem, you should record the parameters that are currently stored in it so you can
reprogram it after flashing. After you have recorded them, send the AT&W1Z command to the the
modem to clear the stored parameters.

1. Run your favorite terminal program.

2. In the program’s terminal window, type AT&V and press E
parameters.

3. Record your parameters by saving the screens and sending them to your printer.

4. Type AT&W1Z and press E
default.

5. Close the terminal program.

Step 6: Upgrade the Modem’s Firmware

Before you begin the following procedure, read the README.TXT file extracted from the upgrade
archive file. Note the file name for the new firmware (example: ARQG125A.HEX). Also, if you are using
Windows NT, you must disable Windows RAS and Microsoft Fax Service before upgrading the modem’s
firmware. To disable RAS and your Fax service, Click Start | Settings | Control Panel, and then double­click Services. Select Remote Access Server , and then click the Startup button. Select Manual as the
startup type, and then click OK. Do the same for any fax service. Close any other programs that might be
accessing the modem’s Com Port.

WARNING: Never install an older version of firmware over a newer version. Doing this WILL DESTROY
THE FLASH PROM! If the flash PROM is destroyed, the modem must be sent in for repair.

1. Run Flash Wizard by double-clicking its icon or file name, or by selecting it from the
Start menu. The program begins by identifying devices attached to your computer.

2. Select the modem to be upgraded, and then click Next to proceed.

Appendix C – Upgrading your Modem

3. Select the port to be upgraded from the Port list, select the appropriate .HEX file from the Hex File
list, and then click Next to continue.

Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.

4. The Progress dialog box now displays the progress of the upgrade.

Caution: Any disruption of the program during this stage of the upgrade can ca use your modem to

become inoperable. Wait for the Next button to become active before proceeding.

5. When the flash upgrade is complete, the message Programming Complete appears. Click Next to
continue.

6. The Results dialog box appears next. Click Finish to exit Flash Wizard.

Note: If you are using Windows NT, be certain to enable RAS and your fax service when the operating

system restarts.

Appendix D – Installing under Linux

Introduction

This appendix explains how to verify that the Multitech MT9234ZPX-UPCI modem has been detected in
Linux Operating System running kernel 2.6.xx.

Assuming that the PCI card has been already installed in the system.
Logon to the system as root.

To check which kernel version the system is running, send the following command
“uname -a”

You should get a response like this:
[root@armadillo ~]# uname -a
Linux armadillo.net 2.6.18-8.el5 #1 SMP Thu Mar 15 19:57:35 EDT 2007 i686 i686 i386 GNU/Linux

This particular system is running kernel 2.6.18-8.el5. For Multitech MT9234ZPX modems, Linux will use
a native driver for the PCI interface already contained in the kernel. Once the system detects the modem
it will assign 2 new ports to the system. Due to the nature of the interface used, two com ports will be
added, but only one com port will be use to access the modem (first port). If you use the second port,
the modem will not respond to any AT command.

To see how many ports the system has detected on boot. Send the following command:
dmesg |grep -i tty

You should get a response like this:

[root@armadillo ~]# dmesg |grep -i tty
serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
00:0f: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
0000:03:00.0: ttyS0 at MMIO 0xcdeffc00 (irq = 169) is a 16550A
0000:03:00.0: ttyS2 at MMIO 0xcdeffe00 (irq = 169) is a 16550A
Bluetooth: RFCOMM TTY layer initialized

The new ports detected and assigned to the card will be labeled as follow. The IRQ and the I/O address
might be different in your system.

0000:03:00.0: ttyS0 at MMIO 0xcdeffc00 (irq = 169) is a 16550A
0000:03:00.0: ttyS2 at MMIO 0xcdeffe00 (irq = 169) is a 16550A

Remember, accessing the modem, you need to always use the first port.
To verify if the modem is operational, you can use the most common terminal emulation in Linux called

minicom. Enter minicom -s

36 Multi-Tech Systems, Inc. MT9234ZPX User Guide

Appendix D – Installing under Linux

This will bring minicom into configuration mode. You should get a response like this:

[root@armadillo ~]# minicom -s

Using AT Commands to Configure Country Code

If you are comfortable using AT commands, you can configure your modem using AT command s. You
must enter these commands in your communication program’s terminal win dow.

To configure the modem for a specific country, execute the following AT commands:

1. Type AT%T19,0,nn (where nn represents the country code). Press Enter.

2. The modem will respond “OK.”

3. Type AT&F&W (this saves changes). Press Enter.

4. The modem will respond “OK.”

5. Type ATI9 (this verifies that country code has been chosen). Press Enter.

6. The modem will display the country code in decimal format followed by an “OK.”

7. Check to be sure the code for your country is displayed.

If not, repeat procedure to correct.

Here are two examples of country, command, and country codes.
