Chapter 1 – Product Overview
Overview
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 digital to analog only once 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 - Installation
Installing on a Windows Computer
Connecting the Modem to Your System
Turn off your computer. Place the modem in a convenient location, then connect it to your computer’s serial port,
to the phone line, to AC power, and to your phone (phone is optional).
1. Connect the Modem to Your PC (RS-232 Connection).
Plug one end of the RS-232 serial cable into the RS-232 connector on the modem, and plug the other end into
a serial port connector on your computer.
2. Connect the Modem to the Telephone Line (Line Connection)
Plug one end of the phone cable into the modem’s LINE jack and the other end into a phone wall jack. The
phone cable is included with your modem.
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.
3. (Optional) Connect the Modem to the Phone.
For voice-only calls, plug a phone into the modem’s PHONE jack.
4. Connect the Power
Make sure the power switch is set to OFF. The power switch is located on the side panel of the modem.
Plug the power supply into a power outlet or power strip. Plug the other end into the PWR jack on the
modem.
CAUTION:
Use only the power supply cable supplied with the modem. Use of any other power supply voids
the warranty and can damage the modem.
Chapter 2 - Installation
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.
The Federal Communications Commission (FCC) and Industry Canada impose certain restrictions on equipment
connected to public phone systems. For more information, see Appendix A.
Connecting Voice (Voice option only)
1. 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 (3.5mm) mini plug. Do not use a monophonic
microphone.
2. Connect the Speaker
For speakerphone or voice mail applications, use a 1/8-inch (3.5mm) 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 - Installation
Installing the Modem Driver on Windows
To install on Windows 2000 or newer:
1. Download the modem driver from http://www.multitech.com/support.go.
2. Make sure your modem is connected properly, and then turn on your computer. Windows should detect your
new modem and open the Welcome to the Found New Hardware wizard.
Note:
If Windows cannot find a modem, your modem may be turned off, or it may be plugged into the wrong
connector on your computer. See Troubleshooting.
3. From the Browse function in the Install Wizard, point to the Temporary folder you created on your local PC to
store the driver that you downloaded from the Multi-Tech website. Windows installs and configures the
modem.
4. Click Finish to exit.
Connecting to the Internet
To access the Internet and Web via your modem, you must establish a dial-up account with an Internet service
provider (ISP). 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 you use the Internet for email and newsgroups, your ISP should also provide you with the following information:
●
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 version 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 2 - Installation
Installing on a Linux Computer
These instructions describe how to install a modem on a computer using RedHat Linux 6.2 operating system.
Other versions of RedHat and other Linux operating systems should be similar. With 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.

Chapter 3 - Operation
Your Multi-Tech modem operates under the control of a communications program. For information on how to
use the modem with your communications program, 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.
Front Panel
About the LED Indicators
The modem has ten LED indicators on the front panel that indicate status and activity:
TD
Transmit Data
Flashes when the modem is transmitting data to another modem.
RD
Receive Data
Flashes when the modem is receiving data from another modem.
CD
Carrier Detect
Lights when the modem detects a valid carrier signal from another modem. It is on when the
modem is communicating with the other modem, and off when the link is broken.
OH
Off-Hook
Lights when the modem is off-hook, which occurs when the modem is dialing, online, or
answering a call. The LED flashes when the modem pulse-dials.
TR
Terminal Ready
Lights when a communication program is using the modem. It means the modem is ready for an
outgoing or incoming call. It goes off when the communication program disconnects the serial
port. When it goes off, a connected modem will disconnect.
Note:
When you turn on the modem, the PWR indicator lights; and if a terminal program is running, the TR
indicator also lights.

Chapter 3 – Operation
Configuring Your Software
You may use either the communication program included with your modem or a third-party program.
Communication programs designed for Windows normally do not need to be manually configured, since they
obtain configuration information from Windows. 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 program’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 auto answer, 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 DIAL TONE),
make sure there is no space between DIAL and TONE in NO DIAL TONE.
9. Refer to the program manual or online help for other configuration choices. In most cases you can accept the
default values.
Configuring Your 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.

Chapter 4 - TroubleshootingChapter 3 - Operation
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, check the list of
troubleshooting procedures before calling Multi-Tech.
If you experience problems, please check the following before calling Technical Support.
Indicators Don’t Light Up
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.
1.
Make sure the modem’s power switch is on, especially if you normally turn the modem on by turning on a
power strip.
2. If the modem is plugged into a power strip, make sure the power strip is plugged in and its power switch is on.
3. Make sure the transformer module is firmly connected to the modem and to the wall outlet or power strip.
4. If the power strip is on and the modem switch is on, try moving the transformer module to another outlet on
the power strip.
5. Test that the outlet is live by plugging another device, such as a lamp, into it.
6. 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 defective.
7. 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.

1. Verify the modem is plugged in and turned on.
2.
Verify 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.)
3. Verify 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.
4. If you don’t get an OK, the problem may still be in the communications program. Verify you have done
whatever is necessary in your software to make a port connection. Not all communication programs connect
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.
5. 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.

Multi-Tech Systems, Inc. MT5656ZDX User Guide
Chapter 4 - Troubleshooting
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.
6. 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. Verify it is firmly connected at
both ends.
7. Is this the first time you have used the cable? If so, it may not be wired correctly. Check the cable description
on the packaging to Verify the cable is the right one for your computer.
8. 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.
9. Windows 9x and 2000: Right-click on My Computer, select Properties from the menu, click on the Device
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.
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 problem goes
away, the first modem may be defective. Call Technical Support for assistance.

Chapter 4 - Troubleshooting
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.
●
Modem incompatibility.
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 DIAL TONE, 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.
●
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 instead 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 Verify 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 4 - Troubleshooting
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.
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.
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.
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 B – 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.
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.
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/en_US/SUPPORT/Updates/drivers/
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 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.
Multi-Tech Systems, Inc. MT5656ZDX User Guide
27
Appendix B – Upgrading the Modem
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 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 for your operating system by clicking
it, and save it in the same folder.
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.
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., 2MBPFL1 1 .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.
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.
When the flash upgrade is complete, the message Programming Complete appears.
4. Click Next. The Results dialog box appears.
5. Click Finish to exit.
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.
