Chapter 1 – Introduction
Ch a p t e r 1 – In t r o d u c t io n
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.
Fe a t u r e s
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
AT Co m m a n d s In f o
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.

Ch a p t e r 2 – In s t a lla t io n
This chapter shows you step-by-step how to set up your Multi-Tech MT9234ZBA modem.
Sa f e t y W a r n in g s
•
•
•
•
•
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.
St e p 1: Ch a n g e t h e In t e r n a l J u m p e r s
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.

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.

St e p 2: Co n n e c t t h e M o d e m t o Yo u r 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.
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”.
St e p 3: In s t a ll t h e M o d e m Dr iv e r
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 operating system, please

Ch a p t e r 3 – O p e r a t io n
Ab o u t t h e Fr o n t Pa n e l
The LED indicators on the front panel indicate status, configuration, 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.
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.
56 – 56K Mode (56,000–28,000 bps). Lights whenever the modem is set for or connects using the V.90 or V.92 protocol.
The actual connection speed depends on ISP server capabilities and line conditions.
33 – V.34 Mode (33,600–2,400 bps). Lights whenever the modem connects using the V.34 protocol.
14 – V.32bis Mode (14,400–7,200 bps). Lights when the modem connects using the V.32bis protocol. The modem can
connect at lower than V.32bis speeds, but no speed indicator lights during the connection.
OH – Off-Hook. Lights when the modem is off-hook, which occurs when the modem is dialing, online, or answering a
call. Flashes when the modem pulse-dials.
TR – Terminal Ready. Lights when a communications program is using the modem. It means the modem is ready for an
outgoing or incoming call. It goes off when the communications program disconnects the serial port. When it goes
off, a connected modem will also disconnect.
EC – Error Correction (V.42). Lights continuously when the modem is in V.42 error correction mode, and flashes when
compression is activated.
FX – Fax. Lights when the modem is in fax mode.
Note: When you turn on the modem, the protocol indicators flash briefly as the modem does a self-test, after which the
56 indicator lights. After a call, the indicator for the protocol used in the connection remains lit until another call is
made or the modem is reset. If you connect at a rate under 14,400 bps, all protocol indicators remain off after the
connection is broken, even though the modem is still turned on.
Le a s e d -Lin e O p e r a t io n
The MultiModemZBA modem can be used on a two-wire leased line.
A leased line is a private, permanent telephone connection between two points. Unlike normal dialup connections, a
leased line is always active. The modems automatically connect when they are attached to the line and are turned on.
Because a leased line is always active, one of the two modems on the line must be configured as the originate modem
and the other as the answer modem; however, it does not matter which is which.
In the event of an interruption, leased-line modems automatically reconnect when the data line or power is restored.
Setup
1.
Open the modem and change jumper J2 to select leased-line operation, and jumper J3 to select either
originate or answer operation, depending upon how you intend to use the modem. See Chapter 2 for the
detailed procedure.
2.
3.
Connect a modular telephone cable to the LINE jack. Connect the other end of the cable to a two-wire
lease-line jack or terminals supplied by the telephone company.
Turn on the modem.

Chapter 4 – Remote Configuration
Ch a p t e r 4 –Re m o t e Co n f ig u r a t io n
Remote configuration is a network management tool that allows you to configure MT9234ZBA modems anywhere in your
network from one location. With password-protected remote configuration, you can issue AT commands to a remote
modem for maintenance or troubleshooting as if you were on site.
Ba s ic Pr o c e d u r e
The following steps can be used when the connection is established by the local or the remote modem.
Note: The remote computer must be running and a communication program must be ready for a data connection, which
will be indicated by a lighted TR indicator on the front of the modem.
1. Establish a data connection with a remote MT9234ZBA modem.
2. Send three remote configuration escape characters followed by AT and the setup password, and press
ENTER. Example: %%%ATMTSMODEM. You have four tries to enter the correct password before being
disconnected. If the password is correct, the remote modem responds with OK.
3. You can now send AT commands to configure the remote modem.
4. When you have finished configuring the remote modem, save the new configuration by typing AT&W0 and
pressing ENTER.
5. Type ATO and press ENTER to exit remote configuration. You can now break the connection in the normal
way.
Se t u p
Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who has the User
Guide knows the default setup password, you should change the password and possibly also the remote configuration
escape character.
Changing the Setup Password
1.
Open a data communications program such as HyperTerminal.
2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the
MTSMODEM password with xxxxxxxx) and press ENTER. The modem responds with OK if the setup
password is correct, and ERROR if it is wrong.
3. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and then
press ENTER. The password can include any keyboard character, and can be up to eight characters long.
The modem responds with OK.
CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the same
case as you set it up.
4. The new password is saved automatically. You can now either enter more AT commands or exit the data
communications program. The next time you wish to set up the modem, you must use the new password.
Changing the Remote Escape Character
To further improve security, you can change a remote modem’s remote configuration escape character either
locally or remotely. The remote configuration escape character is stored in register S9. The factory default is 37,
which is the ASCII code for the percent character (%). Setting S9 to 0 (zero) disables remote configuration
entirely.
CAUTION: If you do this remotely, you won’t be able to change it back remotely.
1. Establish a remote configuration link with the remote modem as described in Basic Procedure.
2. Type ATS9=n, where n is the ASCII code for the new remote configuration escape character, and then
press ENTER.

Chapter 5 – Callback Security
Ch a p t e r 5 – Ca llb a c k Se c u r it y
This chapter describes how to use callback security with your modem. Callback security protects your network from
unauthorized access and helps control long-distance costs. When callback security is enabled, all callers are requested
to enter a password. If a valid password is received, the modem hangs up and returns the call by dialing a phone number
that is stored with the password. The person being called back must then enter the password a second time to establish
a connection.
Up to 30 callback passwords and dialing strings can be stored in the modem. Each dialing string can be up to 34 or 35
characters long and can contain commands as well as phone numbers. For mobile callers, the dialing string can be
programmed to allow the caller to bypass the stored callback number by entering a temporary callback number, to enter
an extension at the callback number, or to make a direct connection without callback.
For local security, the passwords and dialing strings that are stored in the modem are protected from tampering by a
setup password, which you should change when you set up the modem. You can further protect the modem against
tampering by disabling its ability to respond to most AT commands. To check for attempted break-ins, you can request
the modem to display the number of failed password attempts.
Your modem was shipped with a default setup password (MTSMODEM). The same password is used for both callback
security and remote configuration (Chapter 4). Because anyone who has access to this guide has access to the default
password, you should change the password during your initial setup.
Ch a n g in g t h e Se t u p Pa s s w o r d
1. Open a data communications program such as HyperTerminal.
2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the MTSMODEM
password with xxxxxxxx). Press ENTER. The modem responds with OK if the setup password is correct and
ERROR if it is wrong.
3. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and then press
ENTER. The password can include any keyboard character, and can be up to eight characters long. The modem
responds with OK.
4. The new password is saved automatically. You can now either enter more AT commands or exit the data
communications program. The next time you wish to set up the modem, you must use the new password.
CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the same case as
you set it up.
Tu r n in g Ca llb a c k Se c u r it y O n a n d O f f
Callback security must be turned on to enter many callback security commands.
1. Open a data communications program such as HyperTerminal.
2. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password. Press ENTER. The modem
responds with OK if the setup password is correct and ERROR if it is wrong.
3. Type one of the following commands:
•
•
•
To turn off callback security: Type AT#CBS0 and press ENTER. Callers no longer need a password to
connect to the modem, the modem is unable to call them back, and the stored dialing command locations
0–3 become available.
To turn on both local and remote callback security: Type AT#CBS1. Press ENTER. With local security
turned on, you must enter the setup password before you can enter any AT command except the AT, ATIn,
and AT#Sxxxxxxxx commands. For a description of remote callback security, see the following paragraph.
To turn on remote callback security only: Type AT#CBS2 and press ENTER. With remote callback
security turned on, each caller is asked to enter a password, is called back, and then is asked to enter the
password again before a connection can be made. Also, dialing command locations 0–3 for use with the
DS=y dialing command are replaced by callback dialing command locations 0–29.
•
To temporarily disable callback security if the modem is set to #CBS1 or #CBS2 (for instance, to call
another modem): Type AT#CBS3 and press ENTER. The modem returns to its original setting when you
issue the hangup command (+++ATH) or the modem is reset. Note that if a remote modem breaks the
connection, callback security remains disabled.

responds with OK if the setup password is correct and ERROR if it is wrong.
3. Enable callback security by typing AT#CBS1 or AT#CBS2 and pressing ENTER.
4. To store a callback password for the first callback memory location, type AT#CBN0=xxxxxxxx, where xxxxxxxx
is the first password. Press ENTER. The password must be unique, must be six to eight characters in length, and
must not contain a + or - character.
5. To store a callback password for the second callback memory location, type AT#CBN1=xxxxxxxx, where
xxxxxxxx is the second password. Press ENTER. Note that the memory location number in the command is
incremented by one.
6. Repeat as many times as necessary, up to memory location 29, until all passwords are entered.
7. To store a callback phone number in the first memory location, type AT&Z0=[+][-]ATxxxxxxxx[,???], where
xxxxxxxx is the dialing string. Press ENTER. The phone number must be preceded by DT for tone dialing or DP
for pulse dialing. The dialing string can also include other AT commands.
Example: AT&Z0=+-ATM0DT5551212. Up to 35 characters can be used. The +, -, and ??? characters are
optional:
+ Number entry. Enables a mobile caller to enter his current phone number for callback.
-
Direct connection. Enables a caller to choose direct connection without being called back.
,??? Extension entry. Must be used with the + command. Enables a caller to enter an extension number for
callback. The number of ? characters must equal the number of digits in the extension.
8. To store a callback phone number in the second memory location, type AT&Z1=[+][-]ATxxxxxxxx[,???], where
xxxxxxxx is the dialing string, and press ENTER. Note that the memory location number in the command is

Ch a p t e r 6 – Tr o u b le s h o o t in g
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, it is possible that the modem is
defective. However, it is more likely that the source of your problem lies elsewhere. The following symptoms are typical of
problems you might encounter:
•
•
•
•
•
•
•
•
•
•
None of the LEDs light when the modem is on.
The modem does not respond to commands.
The modem cannot connect when dialing.
The modem disconnects while online.
The modem cannot connect when answering.
File transfer is slower than it should be.
Data is being lost.
There are garbage characters on the monitor.
The modem doesn’t work with Caller ID.
Fax and data software can’t run at the same time.
No n e o f t h e In d ic a t o r s Lig h t
When you turn on the modem, the LED indicators on the front panel should flash briefly as the modem runs a self-test. If
the LEDs remain off, the modem is probably not receiving power.
•
Make sure the modem’s power switch is on, especially if you normally turn the modem on by turning on a power
strip.
•
•
If the modem is plugged into a power strip, make sure the power strip is plugged in and its power switch is on.
Make sure the power supply is firmly connected to the modem and the power supply’s power cord is firmly
connected to both to the power supply and the wall outlet or power strip.
•
If the power strip is on and the modem switch is on, try moving the power supply to another outlet on the power
strip.
•
•
Test that the outlet is live by plugging another device, such as a lamp, into it.
The modem or power supply may be defective. If you have another Multi-Tech modem, try swapping modems. If
the problem goes away, the first modem or power supply might be defective. Call Technical Support for
assistance.
CAUTION: Do not under any circumstances replace the power supply with one designed for another product; doing so
can damage the modem and void your warranty.
Th e M o d e m Do e s No t Re s p o n d t o Co m m a n d s
•
•
Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”)
Make sure you are issuing the modem commands from data communication software, either manually in
terminal mode or automatically by configuring the software. (You cannot send commands to the modem from
the DOS prompt.)
•
•
Make sure you are in terminal mode in your data communication 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 communication software.
If you don’t get an OK, the problem may still be in the communication software. Make sure 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.
•
Your communication software settings may not match the physical port to which the modem is connected. The
serial cable might be plugged into the wrong connector—check your computer documentation to make sure. 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.
Multi-Tech Systems, Inc. MT9234ZBA-Series User Guide (S000387A)

Chapter 6 – Troubleshooting
•
If the modem is on, the cable is plugged into the correct port, the communication software is configured
correctly, and you still don’t get an OK, the fault might be in the serial cable. Make sure it is firmly connected at
both ends.
•
•
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 make sure the cable is the right one for your computer.
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.
•
•
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 might have a problem beyond the scope of this user guide. If you have another Multi-Tech modem,
try swapping modems. If the problem goes away, the first modem is possibly defective. Call Technical Support
for assistance.
Th e M o d e m Ca n n o t Co n n e c t W h e n Dia lin g
There can be several reasons the modem fails to make a connection. Possibilities include
•
•
•
•
•
•
•
•
lack of a physical connection to the telephone line.
a wrong dial tone.
a busy signal.
a wrong number.
no modem at the other end.
a faulty modem, computer, or software at the other end.
incompatibility between modems
poor line conditions.
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 DIALTONE, check that the modem’s telephone line cable is connected to both the
modem’s LINE jack (not the PHONE jack) and the telephone wall jack. If the cable looks secure, try replacing it.
If that doesn’t work, the problem might be in your building’s telephone installation. To test the building
installation, plug a telephone into your modem’s telephone 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.
•
If the modem reports BUSY, the other number might be busy, in which case you should try again later.
However, it might indicate that you have failed to add a 9, the 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.
To change the dial prefix in Windows HyperTerminal, select Connect from the Call menu, click Dialing
Properties, and type 9 in the local and long distance boxes in How I dial from this location.
•
•
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 make sure 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.
•
Poor line conditions can affect the connection. When using V.34 or V.32 client-to-client connections in poor
conditions, setting S38=0 may result in better performance.

•
If you are not using Modem on Hold, Call Waiting can interrupt your connection when someone tries to call you.
If you have Call Waiting service, disable it before each call. In most telephone areas in North America, you can
disable Call Waiting by preceding the telephone number with *70 (but first check with your local telephone
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 98 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 telephone 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.
•
Your ISP 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.
M o d e m Ca n n o t Co n n e c t W h e n An s w e r in g
•
The default DTR Control command (&D2) inhibits autoanswer. To enable autoanswer, change DTR Control to
&D0, and make sure &Q0, &Q5, or &Q6 is also set. For more information, see the &D command in the AT
Commands Reference Guide. For information on changing the modem’s default configuration, refer to the &D
command in the AT Commands Reference Guide.
•
Autoanswer might be disabled. Turn on autoanswer in your communications program or send the command
ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.
File Tr a n s f e r Is Slo w e r Th a n It Sh o u ld Be
•
•
If you are using a slow transfer protocol, such as Xmodem, try Zmodem or Ymodem/G instead.
Is your line noisy? If there is static on your line, the modem has to resend many blocks of data to insure
accuracy. You must have a clean line for maximum speed.
•
•
Are you downloading a compressed file with MNP 5 hardware compression enabled? Since hardware data
compression cannot compress a file already compressed by an archiving program, the transfer can be
marginally slower with data compression enabled than with it disabled.
Does your Internet service provider (ISP) use the same 56K protocol as your modem? The default setting of
your modem is to connect using either the V.92 or the V.90 protocol, depending on which one the ISP’s modem
is using. If your ISP uses the V.90 protocol, the maximum speed you will be able to upload at is 33,600 bps.
Check with your ISP to see which protocols it supports.
•
•
Are you trying to send a file to another client modem? If so, then your maximum possible connect speed is
33,600 bps. You can upload at speeds up to 48,000 bps only when connected to an ISP that supports the V.92
protocol.
Try entering the I11 command in online mode or the &V command in command mode to display information

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.
At speeds above 2400 bps, the remote modem might not use the same transmission or error correction
standards as your modem. Try connecting at a slower speed or disabling error correction. (With no error
correction, however, line noise can cause garbage characters.)
•
Try entering the I11 command in online mode or the &V command in command mode to display information

•
Caller ID information is transmitted between the first and second rings, so if autoanswer is turned off (S0=0) or 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 A – Upgrading the Modem’s Firmware
Ap p e n d ix A – Up g r a d in g t h e
M o d e m ’s Fir m w a r e
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 as bugs are fixed or new features are added.
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.
Up g r a d e O v e r v ie w
The upgrade procedure consists of the following steps, which are described in greater detail in the following sections.
1. Identify the model number and firmware version of your modem.
2. Identify the current version of the firmware (you can view this on the Multi-Tech Web site). If your modem
already has the current firmware, there is no need to update it.
3. Download the upgrade file and the appropriate Flash Wizard for your modem.
4. Install the Flash Wizard and extract the firmware .HEX file from the file you downloaded.
5. Document and clear your stored parameters.
6. Upgrade the modem’s firmware using the .HEX file and the Flash Wizard.
7. Restore your parameters.
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 or above, you can use Windows
HyperTerminal.
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 ATI, press ENTER, and record your results. The model number and firmware version should appear
similar to that shown below.
LT V.92 1.0 MT9234ZBA-V-V92 Serial Voice/Data/Fax Modem Version 1.25k
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/SUPPORT/MultiModem ZBA/firmware.asp.
2. Scroll down 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,” you have the current firmware version and do not need to be update.
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.
Step 3: Download the Upgrade File
1. If you are not already at the MultiModem ZBA 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, click the Flash Wizard utility for your operating system to download it, and
save it in the same folder.
Multi-Tech Systems, Inc. MT9234ZBA-Series User Guide (S000387A)
27
Appendix A – Upgrading Your Modem’s Firmware
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 .HEX file into the Flash Wizard folder, which, in a default installation, is at C:\Program
Files\MultiTech Systems\Flash Wizard\.
Step 5: Clear Your Stored Parameters
Before you flash your modem, you should record the parameters that are currently stored in it, so you can reprogram it
after flashing. After you have recorded them, send the AT&W1Z command to the modem to clear the stored parameters.
1. Run your favorite terminal program.
2. In the program’s terminal window, type AT&V and press ENTER to list your modem’s current parameters.
3. Record your parameters by saving the screens and sending them to your printer.
4. Type AT&W1Z and press ENTER to clear your stored parameters and reset your modem to factory default.
5. Close the terminal program.
Step 6: 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 new firmware (example: ARQG125A.HEX).
WARNING: Never install an older version of firmware over a newer version. Doing this 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 modem is turned 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.
4. 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.
5. When the flash upgrade is complete, the message Programming Complete appears. Click Next to continue.
6. The Results dialog box appears next. Click Finish to exit Flash Wizard.
Step 7: 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 ATI in the terminal window and pressing ENTER.

Appendix E – Connecting to a Cisco Router
Ap p e n d ix E – Co n n e c t in g t o a
Cis co Ro u t e r
Connecting to a Cisco Router Console Port
The console port on the Cisco IOS® router is an asynchronous serial port configured as data communications equipment
(DCE). For Cisco 1000, 1600, 2500, 2600, and 3600 series routers, the console port uses an RJ-45 connector.
WARNING: Do not connect the modem to the Cisco router’s auxiliary port. This procedure and document apply only to
the Cisco router’s console port.
Step 1: Configure the Modem for your Country or Region
Configure the modem defaults to match the requirements of the country/region in which it will be used. For
information on how to do this, see “Step 5: Configure the Modem for your Country or Region” in Chapter 2.
Step 2: Configure for Callback Security in Direct Connect Mode
Callback security requires a caller to give a correct password before sending data to the system. If you do not plan to
use this feature, skip to Step 3. Note: Setting the modem for callback security in direct connect mode disables the
remote configuration feature of the modem.
To Turn Direct Connect Callback Security On and Off
Callback security must be turned on to enter many callback security commands.
Using a terminal program such as HyperTerminal, type the command AT#Sxxxxxxxx, where xxxxxxxx is
your password (1 to 8 characters long). Press ENTER. The modem responds with OK if the setup
password is correct and ERROR if it is wrong. The default password is MTSMODEM. If you wish to
change the password, then type the command AT#S=xxxxxxxx, where xxxxxxxx is the new password (1
to 8 characters long), and press ENTER.
Type one of the following commands:
•
•
To turn on remote callback security only, type AT#CBS2 and press ENTER.
To turn on both local and remote callback security, type AT#CBS1 and press ENTER. When local
security is turned on, you must enter the setup password before you can enter any AT command from
a local terminal except the AT, ATIn, and AT#Sxxxxxxxx commands.
Type AT&W0 to store the above commands to nonvolatile memory.
To Set the Parity of the Callback Security Messages
The modem’s password prompt and messages parity must match the parity of the computer to which the
modem is connected.
1. The default parity setting for your modem is no parity (AT#CBP0). To change the modem’s prompt
messages to use even parity, type AT#CBP2 and press ENTER. For odd parity, type AT#CBP1 and press
ENTER.
2. To store the new parity value, type AT&W and press ENTER.
To Assign Callback Passwords
To store a callback password for the first callback memory location, type AT#CBN0=xxxxxxxx, where
xxxxxxxx is the first password. Press ENTER. The password must be unique, must be 6 to 10 characters
in length, and must not contain a + or - character.
To store a callback password for the second callback memory location, type AT#CBN1=xxxxxxxx, where
xxxxxxxx is the second password, and press ENTER. Note that the memory location number in the
command is incremented by one.
Repeat as many times as necessary until all passwords have been entered.
To review your entries, type AT&V and press ENTER.
To set the modem for direct connect mode, type AT%H1 and press ENTER.
To Call a Modem Configured for Callback Security
1. Using a terminal program and an originating modem, dial the number of the modem connected to the
Cisco router, which we will call the “remote modem.”
2. When connection is established, the remote modem responds: Password>
3. Type a direct connection password, and press ENTER. You have three attempts or one minute to enter a
valid password.
4. If the password is valid, the message OK Connecting appears and the modems establish a working
connection.

Appendix E – Connecting to a Cisco Router
Step 3: Console Port Final Setup
Send the following command string to the modem connected to the console port of the Cisco router:
AT%R1&W0
The %R1 command sets E0, Q1, &D0, &K0, $SB9600, and %S1, and the &W0 command stores the commands to
memory. The %R1 command sets the following functions:
E0
Turns command echo off
Q1
Turns result codes off
&D0
&K0
$SB9600
%S1
Ignores DTR from the DTE
Selects no flow control
Sets the serial baud rate to 9600 bps.
Disables command mode at all serial speeds except 115200 bps.
The modem is now configured for use on the Cisco router console port. Note that command echo and result codes
have been turned off. If it becomes necessary to send additional AT commands to the modem after it has been so
configured, there will be little feedback from the modem that it has received and acted upon the command. Only
commands such as ATI0 that request specific data from the modem will send any data to the DTE as an indication
that the modem has accepted the command. Temporarily turning on command echo and result codes might ease
reconfiguration of the modem. When the modem is connected to the console port, turn the modem off and then on
again. This will set the serial baud rate to 9600 bps as the $SB9600 command is implemented.
Console Port Connections
To connect a personal computer to the console port, use the RJ-45-to-RJ-45 roll-over cable and either the RJ-45-to-DB-
25 female DTE adapter or the RJ-45-to-DB-9 female DTE adapter (labeled “TERMINAL”).

Remote Configuration
The configuration of the modem described in Step 3 contains the core settings that allow the modem to function properly
on the console port of the Cisco router. Commands in this section may be done remotely by calling into the MT9234ZBA
attached to the console port with another modem.
Note: Setting country/region configuration and turning on callback security cannot be done remotely. Nor can all
commands be executed remotely if the remote modem is set for callback security; remote configuration of a modem so
configured is not recommended.
Establish a data connection with a remote MT9234ZBA modem.
Send three remote configuration escape characters followed by AT and the setup password, and then press ENTER.
Example: %%%ATMTSMODEM. You have four tries to enter the correct password before being disconnected.
If the password is correct, the remote modem may respond with OK.
Note: If the modem has previously been configured with command echo off and result codes off, it may be difficult to
determine if the remote modem is responding to commands. The ATI command can be used for this purpose.
Even with echo and result codes off, the modem will respond with the requested ID string if it is properly
receiving the command.
You can now send AT commands to configure the remote modem.
When you have finished configuring the remote modem, save the new configuration by typing AT&W0<CR>, then
type ATO<CR> to exit remote configuration. You can then break the connection in the normal way.
Note: This step is important to ensure that the connection is broken cleanly.
