Chapter 1 – Introduction

Chapter 1 – Introduction

Congratulations on your purchase of the MultiModem ZBA modem. You have acquired one of the finest intellige nt
voice/data/fax modems available today from one of the world’s oldest modem manufacturers: Multi-Tech Systems, Inc.
The MT9234ZBA-Series is available in global and non-global builds with and without the voice feature. The MT9234ZBA
global product is approved in 40+ countries. The MT9234ZBA with the voice feature sup ports voice mail and a full-duplex
speakerphone. This allows you and the caller to speak an d listen at the same time.

This user guide will help you to install, configure, test and use your modem.
Check Multi-Tech’s web site for current versions of our product documentation.

Features

Increased Upload Speeds. With the V.92 MultiModem ZBA business modem, you can achieve an u pload speed of 48K
bps (30% increase over V.90 modems). This higher upstream speed reduces data transfer time for large e-mails with
attachments and for ftp site uploads, as well as improves operation for interactive applications.

V.44 Compression. V.44 compression enables data throughput rates of higher than 300K bps - much faster than
V.42bis data compression rates of 150 - 200K bps. For users, it means that your Web browsing will be much faster.

Enhanced Fax Features. The MultiModem ZBA business modem supports V.34 fax and Error Correctio n Mode
providing significant performance and reliability enhancements over previous fax standards. V.34 sends and receives
faxes at 33.6K, more than double the speed of the V.17/14.4K fax standard. Error Correction Mode adds reliablility while
increasing performance of fax transmissions. Together these enhancements increase the performance of the modem to
levels previously only found in more expensive dedicated fax boards and machines.

Remote Configuration. Whether you provide connectivity for a sales office just miles away or for multiple office across
the world, the MultiModem ZBA lets you take care of the configuration from a central site.

Callback Security. The MultiModem ZBA provides password protection and helps reduc e long distance charges for
remote offices and users requiring access to the central site LAN. This modem supports 30 passwords and three
configuration options. With the "fixed" callback option, the central site modem stores a password and the remote user's
phone number. Once the remote site enters their password, the central site's modem calls back using the number stored
in its database. The "variable" option lets users, such as road warriors, enter their fixed password and a ca ll back number
each time they call. The "pass through" option is used to provide the security of password protection, while bypassi ng the
call back process.

Global Approvals. With the globally approved MultiModem ZBA business modem, you need just one modem for
worldwide use. This model has approvals in many countries so you can ship one SKU (stock unit) virtually anywhere in
the world. Localization kits are available for country-specific power cords, phone cords and telco adapters. Go to
www.multitech.com/globalmodem for details.

Chapter 3 – Operation

Chapter 2 – Installat ion

This chapter shows you step-by-step how to set up your Multi-Tech MT9234ZBA modem.

Safety Warnings

• Use this product only with UL- and CUL-listed computers (U.S.A. and Canada)

• To reduce the risk of fire, use only 26 AWG (.41mm) or larger telephone wiring.

• Never install telephone wiring during a lightning storm.

• Never install a telephone jack in a wet location unless the jack is specifically designed for wet locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the

network interface.

• Use caution when installing or modifying telephone lines.

• Avoid using a telephone during an electrical storm; there is a risk of electrical shock from light ning.

• Do not use a telephone in the vicinity of a gas leak.

• This product must be disconnected from the telephone network interface when servicing.

Step 1: Change the Internal Jumpers

This step is required only if:

• You intend to use the modem on a leased line.

• You intend to add a monophonic external speaker to your modem with the voice option. No changes are needed

for stereo.

This will require you to open the modem and move one or more jumpers on the modem’ s printed circuit board.

Warning: The following procedure must be performed by authorized service personnel.
Caution: The circuit board can be harmed by static electricity. Before you open the case, touch a grounded object, such

as the metal chassis of your computer, to discharge any static electricity in your body, then touch the metal shell of the
modem’s RS-232 connector to ensure that there is no voltage difference between you and the modem.

Opening the Modem

1. If the modem is connected, turn it off and remove all connecting cables (including the power and line
cables).

2. Turn the modem upside down.

3. On the bottom of the modem are two screws, which hold the case together. Remove both screws and set
them aside.

4. Turn the modem right side up.

5. Remove the top part of the modem case.

6. To close the modem, reverse Steps 1–5.

8 Multi-Tech Systems, Inc. MT9234ZBA-Series User Guide (S000387A)

Chapter 3 – Operation

Location of the Jumpers

Note: The Speaker Mode Jumper is for the Modem with the Voice Option

Changing the Dial-Up/Leased-Line Jumper

As shipped from the factory, your modem is configured for normal dial-up operation. That is, the modem must
dial a phone number to connect to another modem. To use the modem on a leased line, you must change
jumper J2 to select leased line operation, and J3 to select whether it will be the originating or the answering
modem. If dial-up operation is selected, J3 has no effect.
See Chapter 3 for additional leased line information.

• The factory default is the answer position. This makes the modem the answering modem on the leased

line.

• To use the modem on a leased line, move the J2 jumper plug from the default dial-up position to the

leased line position.

• To make the modem the originating modem on the leased line, move the J3 jumper plug to the originate

position.

Changing the Voice Jumper

The speaker jumper is next to the external speaker jack.

• The factory default position of the voice jumper is set for a stereo speaker or sound card. A jumper plug

covers both pins of the jumper.

• To use the modem with a monophonic external speaker, remove the jumper plug from the jumper pins.

You can store it by placing it on one jumper pin.

Multi-Tech Systems, Inc. MT9234ZBA-Series User Guide (S000387A) 9

Chapter 3 – Operation

Step 2: Connect the Modem to Your PC

Turn off your computer. Place the modem in a convenient location, and then connect it to your computer’s serial port, the
telephone line or leased line, AC power, and, optionally, your telephone.

Connections - No Voice

Connections With Voice

Connect the Modem to Your PC

Plug one end of the serial cable into the RS232 connector on the modem and the other end into a seri al port
connector on your computer, such as COM1 or COM2.

Connect the Modem to the Telephone Line

Plug one end of the modular telephone cable into the modem’s LINE jack and the other end into a standard
phone wall jack.

Important: The LINE jack is not interchangeable with the PHONE jack. Do not plug the telephone into the

LINE jack or the line cable into the PHONE jack.
Note: Regulatory agencies may impose certain restrictions on equipment connected to p ublic telephone

systems. For more information, see Appendix B.

Connect the Two-Wire Leased Line (Leased Line Only)

Plug one end of a two-wire telephone cable into the modem’s LINE jack and the other end to a two-wire
leased line wall jack or terminals.

Note: Before you can use the modem on a leased line, you must first change the internal jumpers. See “Step

2: Change the Internal Jumpers.”

Connect the Modem to a Phone (Optional)

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

Important: The PHONE jack is not interchangeable with the LINE jack. Do not plug the telephone into the

LINE jack or the line cable into the PHONE jack.

Connect a Microphone (Voice Option)

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.

10 Multi-Tech Systems, Inc. MT9234ZBA-Series User Guide (S000387A)

Chapter 3 – Operation

Connect Speakers (Voice Option)

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 unamplified speaker directly into the SPKR jack.

Connect the Modem to the AC Power Outlet

The power switch is located on the right side of the modem. Make sure it is set to OFF.
Attach the appropriate interchangeable blade module to the power supply module. Connect the power lead

from the power supply module into the PWR jack on the modem. Now, plug the power supply module into
your power source.

Note: Use only the power supply supplied with the modem. Use of any other power supply voids the warranty

and can damage the modem.

Power-On Test

Test the modem by turning it on. When you turn it on, the modem performs a diagnostic self-test, after which
the 56 indicator should light. 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, refer to Chapter 6,
“Troubleshooting”.

Step 3: Install the Modem Driver

If you use Windows 2000 or above, you must install the modem driver. The modem driver tells Windows how to control
the modem. If you use a Linux operating system, please refer Appendix D. If you use another oper ating system, please
refer to its documentation for modem installation information.

Installing the Modem Driver

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 6, “Troubleshooting.”

Insert the product CD into your CD-ROM drive, and then click OK.
Windows installs the modem driver.
Click Finish to exit.

Step 4: Configure the Modem for Your
Country or Region – Global Product Only

Different countries have different requirements for how modems must function. Therefore, before you use your modem,
you must configure it to match the defaults of the country/region in which you are using it. You must also do this if you
move the modem to another country/region after it has been configured for the first country/region. You can use one of
two configuration methods:

1. Use the Global Wizard to Configure Your Modem

2. Use AT Commands to Configure Your Modem

Using the Global Wizard to Configure Your Modem

The Global Wizard configuration utility is recommended for computers running Windows 200 0 or newer.

1. Insert the MultiModem ZBA product CD into the CD-ROM drive. The Autorun menu should appear.
