Chapter 1 - Introduction
Chapter 1 - Introduction
Congratulations on your purchase of the Multi-Tech MT5656ZDX-Series modem.
•
•
The Multi-Tech MT5656ZDX modem is your data/fax modem.
The MT5656ZDX-V offers your voice option.
You have acquired one of the finest intelligent data/fax or voice/data/fax modems available today from one of the world’s
oldest modem manufacturers: Multi-Tech Systems, Inc. This user guide will help you install, configure, test, and use your
modem.
Product Description
The Multi-Tech MT5656ZDX and MT5656ZDX-V modems are compatible with the ITU-TV.92 protocol that provide quick
connections, downstream transmissions at speeds up to 56K bps, and upstream transmissions at speeds up to 48K bps
when connected to V.92-compatible Internet Service Providers. The V.92 protocol is able to send downstream from the
Internet to your computer at these speeds because data on the telephone network typically is converted from digitial to
analog only one before it reaches your modem. Upstream transmissions and transmissions between client modems are
limited to 33.6K bps, as are upstream transmissions that are converted more than once on the telephone lines.
Modem features include Plug and Play operation. In standard mode, the modem can store up to four command lines or
telephone numbers of up to 40 characters each in nonvolatile memory. Other modem capabilities include modem-on-hold,
AT&T calling card tone detection, pulse and tone dialing, adaptive answer, V.42bis and V.44 data compression, and self-
resetting lightning protection.
Please note that some V.92 features are turned off in the factory default configuration, and may need to be turned on,
depending on your needs.

Chapter 2 - Hardware Installation
A Note About Power Connection, Surge Protectors, and Lightning
Power surges and other transient voltages on power lines, such as those caused by lightning strikes, can
damage or destroy your modem. Therefore, we recommend that you plug the modem into a surge protector
rather than directly into a wall outlet, preferably a surge protector that provides protection against electrical
spikes on the phone line as well as on the power line. Note that not even a surge protector can guard against
damage from a nearby lightning strike. During an electrical storm, it is safest to unplug your computer
equipment from both the power outlet and the phone line.
Power-On Test
Test the modem by turning it on (an on-off switch is located on the side panel). When you apply power, the
modem performs a diagnostic self-test. The PWR indicator lights; and if a terminal program is running, the TR
indicator also lights. If this does not happen, check that the power switch is on, the power supply is solidly
connected, and the AC outlet is live. If these measures do not work see the Troubleshooting chapter.
Note: The Federal Communications Commission (FCC) and Industry Canada impose certain restrictions on
equipment connected to public phone systems. For more information, see Appendix B.
UsingYour Modem
Right now the modem is set up for the most typical user application, that is, the modem is set to make dial-up calls to remote
installations where the calls are answered automatically. Therefore, you shouldn’t need to change the current default
configuration.
You will likely use your data communications software to:
• Launch a data communications session through a set of modem configurations which you select and then
associate with a target phone number. Once you have created, saved, and named this set of information
according to your connection needs and your data communications software’s conventions, the software
then simplifies your dialing. You need not reconfigure the modem nor run the risk of mistakenly keying-in
incorrect information, or
• Enter terminal mode, where you can issue AT commands .

Connect the Microphone
For voice mail or speakerphone applications, plug an unamplified microphone into the MIC jack on the side of
the modem. The microphone should have a stereo 1/8-inch mini plug. Do not use a monophonic microphone.
Connect the Speaker
For speakerphone or voice mail applications, use a 1/8-inch-plug male-to-male stereo patch cord to connect
the SPKR jack on the side of 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. The stereo male-to-male patch cord can be purchased at a local PC
retail store.
If you do not have a sound card, you can plug an amplified speaker directly into the SPKR jack.

Chapter 2 - Hardware Installation
Installing the Modem Driver
If you use Windows 95/98/Me/2000/NT/XP, you must install the modem driver.
If you use another operating system, see Appendix E.
When operating the modem under Windows 95/98/Me/2000/XP, the modem driver can be installed by using the Plug and
Play feature. Follow the 4-step procedure below.
1. Make sure your modem is connected properly, and then turn on your computer. Windows should detect your new
modem and open the Install New Modem wizard.
Note: If Windows cannot find a modem, your modem may be turned off, it may be plugged into the wrong connector on
your computer, or the serial cable may be faulty. See “None of the LEDs Light When the Modem Is Turned On” and
“The Modem Does Not Respond to Commands” in the “Troubleshooting” chapter in the User Guide.
2. Insert the MT5656ZDX CD, and then click OK.
3. Windows installs and configures the modem.
4. Click Finish to exit.
For Windows NT, the Install New Modem wizard has one prompt before Step 2. Select Don’t detect my modem; I will
select it from a list, and then click Next. A dialog box with a list of manufacturers and a list of modem models appears.
Then continue with Step 2 above.
Removing an Old Modem Driver
When your new modem replaces another modem, the old modem driver remains in Windows, and the old modem driver
is still selected in HyperTerminal and other Windows applications. Though you can change the application connection
descriptions one at a time, it is easier to force the Windows applications to use the new modem by removing the old modem
driver from Windows.
1.

3.
4.
5.
Click the Start button, point to Settings, and click Control Panel.
Double-click the Modems icon to open the Modems Properties dialog box.
In the list box, select the old modem.
Click Remove, and then click Close.
The next time you dial a HyperTerminal connection, it will select your new modem and ask you to confirm the selection.
InstallingYour Data Communications Software
Data communications software is designed to send and receive messages. Multi-Tech includes data communications
software with your modem. However, the modem will work with most data communications software. To install the data
communications software provided with this modem, insert the CD into the CD-ROM drive and click on the Phone Tools
icon. You will be asked to choose your language. The software will automatically load onto your PC.
Note: Data communications software running in a Windows operating system normally do not have to be configured since
they use the Plug and Play configuration supplied by the Windows modem driver. Data communications software running in
DOS or other operating systems may need to be manually configured. See Chapter 3, Operations.

Chapter 2 - Hardware Installation
Connecting to the Internet
Your Multi-Tech modem is your gateway to the Internet and the World Wide Web. To access the Internet and Web via your
modem, you must establish a dial-up account with an Internet service provider (ISP). To locate an ISP near you, look in a
local directory or computer publication. Your ISP should provide you with the following information:
• User name (also called user ID)
• Password
• Access number (the number you call to connect to the server)
• Host name and/or domain name
• Domain Name Server (DNS) server address
If, besides the Web, you use the Internet for email and newsgroups, your ISP should also provide you with the following in-
formation:
• Email or POP mail address
• POP server address
• Mail or SMTP address
• News or NNT server address
Dial-Up Networking
Before you can connect to the Internet, you must set up a remote-node client program on your computer. The Windows ver-
sion is called Dial-Up Networking. Dial-Up Networking establishes your connection to the ISP’s server, which is the shared
computer that manages calls from clients (your computer) to the Internet. Most, if not all, Windows browsers start Dial-up
Networking automatically when you open them.
For instructions on how to set up Dial-Up Networking, consult your ISP or your operating system’s online help or printed
documentation. Many ISPs include with their service a program that will instruct and configure Dial-Up Networking automatically
for you.

Chapter 3 - Operation
Chapter 3 - Operation
Like any modem, your Multi-Tech modem operates only under the control of a communications program, such as the
communications program included with your modem. It also operates under other general-purpose data communication
programs, such as Windows Terminal and HyperTerminal. For information on how to use the modem with the
communications program of your choice, please refer to the documentation provided with the data communications program.
An experienced modem user can configure the program’s software to change the way the software interacts with a modem
and configure the modem to change the way it operates.
About the LED Indicators
The modem has ten LED indicators on the front panel that indicate status and activity:
Figure 2–1. Front panel

Chapter 3 - Operation
ConfiguringYour Software
You may use either the communication program included with your modem or a third-party program. Communication
programs designed for Windows 95 and above normally do not need to be manually configured, since they obtain
configuration information from Windows. Communication programs designed for DOS and other operating systems,
however, may need to be manually configured to work with your modem. Though each communication program is different,
the following procedure should work with most of them.
1. Turn on your computer and run your communications program.
2. Find the dialog box or menu that lets you select your modem. (In Windows Terminal select Settings |
Modem Commands; in HyperTerminal select File | Properties | Phone Number; and in the
communications program select Configure | General Configuration | Communication | Change
Modem.
3. Choose your modem from the program’s modem list. If it isn’t listed, choose a generic modem and modify
the settings as necessary.
4. Change the modem initialization string, if necessary. The factory default configuration works well for most
purposes. To load the factory default configuration, use AT&F. To load a custom configuration that was
saved using the &W command, use ATZ. Note that the Z command must be in a command string by itself.
For a Macintosh, the initialization string should include the &D0 command. If you do not want the modem
to always answer the phone, add S0=0 to the string. To use Caller ID with the modem, add S0=2 to the
string (Caller ID information is sent between the first and second rings, so the phone must ring at least
twice before the modem picks up the line). Depending on the software, you might have to end the string
with a carriage return character (^M).
Note: To change the modem’s default configuration, type new commands in the communication pro-
gram’s terminal window, adding the &W command to store them in the modem’s nonvolatile memory. For
instance, to create a default configuration for a Macintosh computer that turns off autoanswer, type
AT&F&D0S0=0&W. The new configuration loads automatically whenever the modem is turned on or
receives the ATZ command.
5. Select the port the modem is connected to (normally COM1 or COM2).
6. Select your serial port speed. This can be labeled “maximum speed,” “DTE bps,” or “baud rate.” Ideally, if
you use data compression, you should set your serial port baud rate to four times the modem’s maximum
transmission speed or faster; however, few files can be compressed enough to require speeds that high,
and not all serial ports can handle speeds that high.
7. If the communication program has an autobaud selection, make sure it is disabled. Autobaud applies only to
older modems, and can cause problems if enabled.
8. If the program allows you to edit the no-connect messages (NO CARRIER, BUSY, NO ANSWER, NO
DIALTONE), make sure there is no space between DIAL and TONE in NO DIALTONE.
9. Refer to the program manual or online help for other configuration choices. In most cases you can accept
the default values.
ConfiguringYour Modem
Your modem normally is configured through Windows or through the communication program you are using. The default
settings work best for most purposes. However, you also can configure your modem by sending AT commands to the
modem. See the AT Command Reference Guide for a list of AT (data) commands and how to use them.

Sending a Fax
With your data communications software, you can use your modem to send and receive faxes directly from your computer.
The following steps show you how to fax a document directly from a Windows application without opening the data communi-
cations program.
1. Create a document in a Windows application, such as Word, a graphics editor, or a spreadsheet. Keep
the application and the document open, and select Print from the File menu.
2. Select CAPTURE FAX BVRP as the printer driver, and then click OK. The Send Fax wizard appears.
3. In the Recipient section, type the required information or extract it from the Phone Book by clicking
this icon.
4. In the Template section, optionally select a cover page and type a cover message.
5. Select the document to be sent. The default file when sending from within a Windows application is
Capture.dgr.
6. Select the date and time to send the document, if you do not want to send it immediately.
7. Click Finish to start the transmission.

Chapter 5 - Troubleshooting
Chapter 5 - 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, check the list of troubleshooting procedures
before calling Multi-Tech.
• None of the LEDs light when the modem is on.
• The modem does not respond to commands.
• The modem dials but is unable to make a connection.
• 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.
If you experience problems, please check the following possibilities before calling Technical Support (refer to
Appendix A).
None of the Indicators Light
When you turn on the modem, the PWR indicator and the terminal turn on. If the LEDs remain off, the modem is probably not
receiving power.
✔
✔
Make sure the modem’s power switch is on, especially if you normally turn the modem on by turning on a
power strip.
If the modem is plugged into a power strip, make sure the power strip is plugged in and its power switch is
on.
✔
✔
Make sure the transformer module is firmly connected to the modem and to the wall outlet or power strip.
If the power strip is on and the modem switch is on, try moving the transformer module to another outlet on
the power strip.
✔
✔
Test that the outlet is live by plugging another device, such as a lamp, into it.
The modem or the DC power transformer may be defective. If you have another Multi-Tech modem, try
swapping modems. If the problem goes away, the first modem or the DC power transformer may be defec-
tive. Call Technical Support for assistance.
CAUTION: Do not under any circumstances replace the transformer module with one designed for another
product; doing so can damage the modem and void your warranty.

Chapter 5 - Troubleshooting
The Modem Does Not Respond to Commands
✔ Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”)
✔ Make sure you are issuing the modem commands from the data communications program, 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 AT and press ENTER.
If you get an OK response from your modem, your connections are good and the problem likely is in the
connection setup in your communications program.
✔
If you don’t get an OK, the problem may still be in the communications program. Make sure you have done
whatever is necessary in your software to make a port connection. Not all communication programs con-
nect to the COM port automatically. Some connect when the software loads and remain connected until
the program terminates. Others can disconnect without exiting the program. The modem’s TR indicator
lights to show that the software has taken control of the modem through the COM port.
✔
✔
Your communications program settings may not match the physical port the modem is connected to. The
serial cable might be plugged into the wrong connector—check your computer documentation to make
sure. Or you might have selected a COM port in your software other than the one the modem is physically
connected to—compare the settings in your software to the physical connection.
If the modem is on, the cable is plugged into the correct port, the communications program is configured
correctly, and you still don’t get an OK, the fault might be in the serial cable. Make sure it is firmly connect-
ed at both ends.
✔
✔
Is this the first time you have used the cable? If so, it may not be wired correctly. Check the cable descrip-
tion on the packaging to make sure the cable is the right one for your computer.
Peripheral expansion cards, such as sound and game cards, might include a serial port preconfigured as
COM1 or COM2. The extra serial port, or the card itself, may use the same COM port, memory address, or
interrupt request (IRQ) as your communication port. Be sure to disable any unused ports.
Windows 9x and 2000: Right-click on My Computer, select Properties from the menu, click on the De-
vice Manager tab, double-click on Ports, then double-click on the communication port your modem is
connected to. In the port’s Properties sheet, click on the Resources tab to see the port’s input/output
range and interrupt request. If another device is using the same address range or IRQ, it appears in the
Conflicting Device List. Uncheck Use automatic settings to change the port’s settings so they do not
conflict with the other device, or select the port the conflicting device is on and change it instead. If you
need to open your computer to change switches or jumpers on the conflicting device; refer to the device’s
documentation.
Windows NT 4.0: To look for address or IRQ conflicts, click Start, Programs, Administrative Tools (Com-
mon), and Windows NT Diagnostics. In the Windows NT Diagnostics dialog box, click the Resources
tab to see which input/output ranges and interrupt requests are in use. If you need to open your computer
to change switches or jumpers on the conflicting device; refer to the device’s documentation.
✔
✔
The serial port might be defective. If you have another serial port, install the modem on it, change the COM
port setting in your software, and try again.
The modem may be defective. If you have another Multi-Tech modem, try swapping modems. If the prob-
lem goes away, the first modem may be defective. Call Technical Support for assistance (Refer to
Appendix A).

Chapter 5 - Troubleshooting
The Modem Dials But Cannot Connect
There can be several reasons the modem fails to make a connection. Possibilities include:
• lack of a physical connection to the telephone line.
• a missing 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.
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 ENTER.
When you dial again, the modem reports the call’s progress.
✔
If the modem reports NO DIALTONE, check that the modem’s phone line cable is connected to both the
modem’s LINE jack (not the PHONE jack) and the phone wall jack. If the cable looks secure, try replacing
it. If that doesn’t work, the problem might be in your building’s phone installation. To test the building
installation, plug a phone into your modem’s phone wall jack and listen for a dial tone. 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 your PBX 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).
✔
If the modem reports BUSY, the other number might be busy, in which case you should try again later, or it
might indicate that you have 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 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 95 HyperTerminal, select Connect from the Call menu, click Dialing
Properties, and type 9 in the local and long distance boxes in How I dial from this location.
✔
✔
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 answeredinstead 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 another modem is answering the call, and
the modems might be having problems negotiating because of modem incompatibilities or line noise. Try
connecting at a lower speed.

Chapter 5 - 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 phone areas in
North America, you can disable Call Waiting by preceding the phone number with *70 (check with your
local phone 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). To change the dial prefix
in Windows Terminal, select Settings | Modem Commands. To change it in HyperTerminal, select
Connect from the Call menu, click Dialing Properties, check This location has Call Waiting, and 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 for loose connections between the modem and the computer, the phone jack, and AC power.
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.
✔
If you were online, it 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 data communications program or send the
command ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.
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 communications program.
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.
Try entering the &V1 command to display information about the last connection, making a screen print of
the connection statistics, and checking for parameters that might be unacceptable.
The Modem Doesn’t Work with Caller ID
✔
Caller ID information is transmitted between the first and second rings, 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.

Appendix D - Installing a Modem in Linux
Appendix D - Installing a Modem in
Linux
This appendix explains how to install a modem on a PC operating under the RedHat Linux 6.2 operating system. Other
versions of RedHat and other Linux operating systems should be similar. Briefly, in Linux, you do not need drivers for most
standard external modems and most internal ISA bus modems. Programs in Linux commonly call upon the port, rather than
the modem.
Standard Linux Serial Port Definitions
Port
Linux Port
Com 1
Com 2
Com 3
Com 4
ttyS0
ttyS1
ttyS2
ttyS3
Installation
Connect the external modem to an available serial port.
Setup
This section describes how to make sure Linux can talk to the modem and be able to dial up to the Internet.
Using the terminal program Minicom to verify operation
1. At the command prompt, type minicom –s and press ENTER.
2. Select Serial port setup and press ENTER.
3. From Serial port setup, use the A key to access Serial Device, and then press ENTER.
4. Press ESC.
5. You are now in the Minicom terminal. Type AT and press ENTER. The screen should display OK to verify the
operation. Alternately, dial a phone number to verify line operation
6. To leave Minicom, press CTRL + A, and then press Z.
7. On the help menu, press X to exit.
Using the modem to call the Internet
Linux allows different graphic user interfaces (GUI). In the following steps, we’ll use the Gnome Desktop GUI
and assume that the Internet Service Provider (ISP) you are calling assigns you the Domain Name Service
(DNS) and Internet Protocol (IP) addresses. For more information on DNS or IP, see the Linux OS owner’s
manual or contact your ISP.
1. On the Task Bar at the bottom of the screen, select the Gnome Footprint.
2. Select Internet from the menu.
3. Select Dialup Configuration Tool.
4. Select Add, and then click Next.
5. Enter the connection name and phone number, and then click Next.
6. Enter your user name and password, and then click Next.
7. Select Normal ISP if your ISP is not listed, and then click Next.
8. Click Finish.

Appendix D - Installing a Modem in Linux
Calling the ISP
1. On the Task Bar at the bottom of the screen, select the Gnome Footprint.
2. Select Internet from the menu.
3. Select RH PPP Dialer.
4. Select the connection name you entered in step 5 of the previous section.
5. Click OK.
That’s basically it. Linux can use different programs and desktops depending on who made the Linux operating
system and what version it is. The above procedures use the most commonly installed components of Red Hat
6.2. More details can be found in in the Linux OS owner’s manual.
To use the system for answering calls, Linux requires other programs to be installed, such as Mgetty,
Mgetty+Sendfax and others, depending what you require. Each vendor of Linux usually has more than
adequate information on installing these programs.

Appendix E - Upgrading the Modem
Appendix E - Upgrading the Modem
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 update it.
3. Download the upgrade file for your modem.
4. Extract the firmware .HEX file and the appropriate flash upgrade program 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 upgrade program.
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
update it.
1. Run your favorite terminal program. If you are using Windows 95, 98, 2000 or Windows NT, you can use
HyperTerminal. If you are using Windows 3.1, you can use Windows Terminal.
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 ENTER. If the modem does not respond with OK, repeat the
AT&F command.
3. Now type ATI3 and record your results. The firmware version should appear first in the response, which
should look similar to the following:
V2.300G-V90_2M_DLS
Step 2: Identify the Current Firmware Version
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 update it.
1. Using your favorite Web browser, go to http://www.multitech.com/support/MultiModemZDX/firmware.asp.
2. Scroll down the table 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 updated.
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: Download the Up-
grade 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 MultiModemZDX firmware page of the Multi-Tech Web site, follow the proce-
dure 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 for your operating system by
clicking it, and save it in the same folder.

Appendix E - Upgrading the Modem
Step 4: Extract the Upgrade Files
1. Install the Flash Wizard utility by double-clicking the 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 .S37 file into the Flash Wizard folder, which, in a default installation, is at C:\Program
Files\MultiTech Systems\Flash Wizard\.
Step 5: 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 boot code (e.g., 2MBPFL11.S37) and the file name for the new firmware (e.g., BkQg300G.hex).
Warning: Never install an older version of firmware over a newer version. Doing so 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
Identifying Devices dialog box is displayed as Flash Wizard locates and identifies the devices connected
to your system.
Note: If the message ERROR: No valid devices detected is displayed, verify that the device is powered on
and that all cables are correctly and securely attached.
2. Click the modem to be upgraded, and then click Next to proceed.
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 appears, showing a status bar that indicates the progress of the upgrade.
Caution: Any disruption of the program during this stage of the upgrade can cause 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.
Step 6: Restore Your Parameters
Your modem has been updated. You can now open your terminal program to reprogram your modem parameters or to
confirm the update by typing ATI3 in the terminal window and pressing ENTER.
