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
The MultiModemZDX and MultiModemZDXV modems incorporate the V.90
protocol, which enables Internet connections at data rates up to 56K bps over
standard phone lines. These protocols are able to send data downstream to your
computer at high 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 FCC-
registered for connection to phone networks without notification to the phone
company.
Features

Connecting the Modem to Your System
Connections for the MT5600ZDX
Turn off your computer. Placing the modem in a convenient location, connect it
to your computer’s serial port, to the phone line, to AC power, and to your phone.
PWR RS232 PHONE LINE
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
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 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 diagnostic self-test. The 56 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 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 .

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 1/8-
inch 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.

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.
4. Click Remove, and then click Close.
5. The next time you dial a HyperTerminal connection, it will select your new
modem and ask you to confirm the selection.
Loading Data Communications Software
MultiTech includes a data communications software package on the product CD
shipped with your modem. In general, however, the modem will work with most
data communications software packages. Data communications software gives the
user access to lower-level commands that govern (at a detailed technical level) how
the modem operates, that is, how the modem handles incoming and outgoing data
streams, etc.
Load the software as you would any Windows application program. During instal-
lation under Windows NT/2000/Xp, an advisory screen may appear saying “FAX
capture driver installation” and causing a delay in the installation. Be aware that
this is normal and the installation process has not failed or stalled. Simply wait a
few moments until this screen disappears.

2 Installation
12
Installing Your Data Communications Software
Data communications software is designed to send and receive messages. Multi-
Tech 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 CD-
ROM drive. The software will then install automatically if you have Windows 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.
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

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
communications 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.

Introduction
Like any modem, your Multi-Tech modem operates only under the control of a
communications program, such as the communications software package
(PhoneTools) 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 Communications 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.
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 &Wcommand, use ATZ. Note that the Zcommand 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.
