Chapter 1 – Introduction

Congratulations on your purchase of the MultiModem ZBA modem. You have acquired one of the finest intelligent

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 supports voice mail and a full-duplex

speakerphone. This allows you and the caller to speak and 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 upload 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 Correction 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 reduce 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 call back number

each time they call. The "pass through" option is used to provide the security of password protection, while bypassing 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.

AT Commands Info

The AT Commands, S-Registers, and Result Codes for the MT9234ZBA-Series Modems are published in a separate

Reference Guide. This guide is included on the MT9234ZBA-Series product CD. You can open the guide from the CD or

you download the guide to your hard drive and then open it.

Chapter 2 – Installation

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 lightning.

•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.

Chapter 3 – Operation

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

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.

Chapter 3 – Operation

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

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 serial 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 public 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.
