Introduction
Congratulations on your purchase of the MultiModemZDX or the
MultiModemZDXV modem. 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 manual will help you install,
configure, test, and use your modem.
Product Description
1 Introduction
Features
The MultiModemZDX and MultiModemZDXV modems incorporate the K56flex
and V.90 protocols, both of which enable Internet connections at data rates up to 56K
bps over standard phone lines. These protocols are able to send data downstream to
your compute r a t h i g h speeds by taking advantage of the fact that data on the phone
network normally is converted from digital to analog only once before it reaches your
modem. Upstream transmissions and transmissions between client modems have a
maximum data rate of 33.6K bps. Line conditions may cause modems to connect at
speeds lower than the stated data rate maximums.
The MultiModemZDX and MultiModemZDXV modems offer interactive automatic
dialing and command mode configuration. You can store four command lines or
phone numbers of up to 31 characters each in the modem’s nonvolatile memory. The
modem pulse-dials or tone-dials, and recognizes dial tones and busy signals for
reliable call-progress detection. It can also detect AT&T calling card tones. It is FCCregistered for connection to phone networks without notification to the phone
company.
™
General Features
• Complies with major ITU-T, TIA, and EIA international standards to ensure
compatibility with other modems.
• Uses DTMF and tone detection to distinguish data and fax calls when used
with software that supports these features.
• Supports serial port speeds to 230.4K bps with compatible serial ports.
• Supports Caller ID (North American versions only).
Data Features
• Supports ITU-T V.90 and K56flexTM speeds plus 33.6K, 31.2K, 28.8K, 26.4K,
24K, 21.6K, 19.2K, 16.8K, 14.4K, 12K, 9.6K, 7.2K, 4.8K, 2.4K, 1.2K, and 0–300
bps.
Note: Under the 56K bps standards, you can asymmetrically download data
from an ISP at speeds up to 53K bps, but upload only at speeds up to 33.6K bps.
Client-to-client operation is also limited to 33.6K bps.

• Automatically disables compression when transferring already-compressed
files.
• Can autodial, redial, pulse (rotary) and touch-tone dial.
• Detects dial tones and busy signals for reliable call-progress detection.
• Compatible with the standard AT command set used by most communication
programs.
• Supports the H.324 protocol (videophone ready).
• Supports Plug and Play (PnP).
• Routes voice, data, or fax calls on a single phone line using distinctive rings.
• Can be flash upgraded.
Fax Features
• Supports V.17, Class 1, Class 2, and Group 3 fax standards, allowing the
MultiModem fax to communicate with other fax modems as well as with fax
machines.
• Sends and receives faxes from your computer at 14,400 bps, 9600 bps, 7200 bps,
4800 bps, 2400 bps, or 300 bps.

to your computer’s serial port, to the phone line, to AC power, and to your phone.
PWR RS232 PHONE LINE
2 Installation
Figure 2–1. MT5600ZDX Connections.
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, such as COM1 or
COM2. You supply the RS-232 cable.
2. Connect the Modem to the Phone Jack (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

7
2 Installation
3. (Optional) Connect the Modem to the Phone
For voice-only calls, plug a phone into the modem’s PHONE jack.
4. Connect the Modem to the AC Power Outlet
Plug the DC power transformer into an AC power outlet or power strip. Plug the
DC power transformer into the POWER jack on the modem.
Note: Use only the DC power transformer supplied with the modem. Use of any
other transformer voids the warranty and can damage the modem.
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 diagnost ic s el f-test. The 56 indic ator
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 Chapter 5,
Troubleshooting.
Note: The Federal Communications Commission (FCC) and Industry Canada
impose certain restrictions on equipment connected to public phone systems. For
more information, see Appendix A.
Using Your 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 .

Connections for the MT5600ZDXV
PWR RS232 PHONE LINE
2 Installation
Figure 2–2. MT5600ZDXV Connections
1. Follow All of the Connection Directions for the MT5600ZDX
The add these steps:
2. 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 1/8inch mini plug. Do not use a monophonic microphone.
3. 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.
9
Installing the Modem Driver
If you use Windows 95/98/2000 or Windows NT 4.0, you must install the modem
driver. The modem driver is used by Windows to control the modem. If you use
Windows 3.1 or another operating system, skip this step and go to Chapter 3. If you
are using a Linux operating system, see Appendix F.
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 Chapter 5, “Troubleshooting.”
2. In the Install New Modem wizard, 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.

8. Click Finish to exit.
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. Click the Start button, point to Settings, and click Control Panel.
2. Double-click the Modems icon to open the Modems Properties dialog box.
3. In the list box, select the old modem.

5. The next time you dial a HyperTerminal connection, it will select your new
modem and ask you to confirm the selection.
10
Installing Your Data Communications Software
Data communications software is designed to send and receive messages. MultiTech includes a data communications program with your modem. However, the
modem will work with any data communications software. To install the data
communications software provided with this modem, insert the CD into the CDROM drive. The software will then install automatically if you have Windows 95/
98/2000 or Windows NT 4.0.
For other operating systems, insert the CD into your CD-ROM drive, click the Start
button, and then click Run. Type D:\setup.exe, and then click OK. If your CD-ROM
drive uses a different drive letter, type that letter in place of D. The setup wizard on
the CD guides you through the installation.
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, Advanced Options.
2 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 e-mail and newsgroups, your ISP should
also provide you with the following information:
• E-mail or POP mail address
• POP server address
• Mail or SMTP address
• News or NNT server address
11
Dial-Up Networking

Introduction
Like any modem, your Multi-Tech modem operates only under the control of a
communications program, such as the communications program included with
the 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.
Configuring Your Software
For Windows 95/98/2000 and Windows NT:
Communication programs designed for these operating systems normally do not
need to be manually configured, since they use the Plug and Play configuration of
the Windows modem driver.
For DOS and Other Operating Systems:
Communication programs designed for DOS and other operating systems, however,
may need to be manually configured to work with your modem. Though each
communications program is different, the following procedure should work with
most of them.
3 Advanced Options
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 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.
• Set the serial port baud rate to 115,200 bps if your computer has a high speed
serial port with a 16550AFN UART or equivalent and Windows 95 or NT 4.0
• Set it to 57,600 bps if it has Windows 3.1x. If you have an older computer with
a 14550 UART, set it to 19,200 bps.
• Older Macintosh computers can use a serial port baud rate of 57,600 bps;
newer ones can use a serial port baud rate of 115,200 bps or 230,400 bps.
To see what UART your serial port uses if you have Windows 3.1x, in Program
Manager select File | Run, type MSD, and press E
the UART type. If you have Windows 95 or 98, select Start | Settings | Control
Panel, and double-click on the Modems icon. In the Modems Properties dialog
box, click the Diagnostics tab, click the port the modem is connected to, and
click More Info to see the UART type. Note that both programs will identify a
14550 UART as an 8250A UART. If you have an 80386 or later computer, your
UART is most likely a 14550 or 16550AFN.
NTER. Select COM Ports to see
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.
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 Chapter 4 for a list of AT commands and how to use them.

4 AT Commands, S-Registers, and Result Codes
Using
AT
Commands to Configure Your Modem
AT commands are used to control the operation of your modem. They are so called
because each command must be preceded by the characters AT to get the ATtention
of the modem.
AT commands can be issued only when the modem is in command mode or online
command mode. The modem is in command mode whenever it is not connected to
another modem. The modem is in data mode whenever it is connected to another
modem and ready to exchange data. Online command mode is a temporary state in
which you can issue commands to the modem while connected to another modem.
To put the modem into online command mode from data mode, you must issue an
escape sequence (+++) followed immediately by the AT characters and the command,
e.g., +++ATH to hang up the modem. To return to data mode from online command
mode, you must issue the command ATO.
To send AT commands to the modem you must use a communications program,
such as the HyperTerminal applet in Windows 95, 98, NT 4.0 and Windows 2000, or
the communications program included with this modem. You can issue commands
to the modem either directly, by typing them in the terminal window of the
communications program, or indirectly, by configuring the operating system or
communications program to send the commands automatically. Fortunately,
communication programs make daily operation of modems effortless by hiding the
commands from the user. Most users, therefore, need to use AT commands only
when reconfiguring the modem, e.g., to turn autoanswer on or off.
The format for entering an AT command is ATXn, where X is the command and n is
the value for the command, sometimes called the command parameter. The value is
always a number. If the value is zero, you can omit it from the command; thus,
AT&W is equivalent to AT&W0. Most commands have a default value, which is the
value that is set at the factory. The default values are shown in the “AT Commands
Reference” section, which begins on the next page.
You must press ENTER to send the command to the modem. Any time the modem
receives a command, it sends a response known as a result code. The most common
result codes are OK, ERROR, and the CONNECT messages that the modem sends to
the computer when it is connecting to another modem. For a table of valid result
codes, see “Result Codes” at the end of this chapter.
You can issue several commands in one line, in what is called a command string. The
command string begins with AT and ends when you press ENTER. Spaces to separate
the commands are optional; they are ignored by the command interpreter. The most
familiar command string is the initialization string, which is used to configure the
modem when it is turned on or reset, or when your communications program calls
another modem.
