Chapter 2 – Installation
Chapter 2 - Installation
Step 1 - Connect the Modem to Your System
Turn off your computer. Placing the modem in a convenient location, connect it to your computer’s serial
port, to the telephone line, to your leased line, to AC power, and, optionally, to your telephone.

Chapter 2 – Installation
Connect the Phone to the Modem (Optional)
For voice-only calls, plug a telephone into the modem’s PHONE jack.
Connect the Modem to the AC Power Outlet
Plug the power transformer into an AC power outlet or power strip. Plug the power transformer’s
cable into the POWER jack on the modem.
Note: Use only the power transformer supplied with the modem. Use of any other transformer
voids the warranty and can damage the modem.
Power-On Test
Test the modem by turning it on (a power switch is located on the front panel). When you apply
power, the modem performs a diagnostic self-test, indicated by the TM indicator lighting for a few
seconds, after which the LCD should light. If this does not happen, check that the power switch is
on, the power transformer is solidly connected, and the AC outlet is live. If these measures do not
work, see the “Troubleshooting” chapter.
Step 2 - Install the Modem Driver
If you use Windows 2000 or newer, you must install the modem driver. The drivers are installed easily
since Windows supports Plug-and-Play.
Installing the Modem Driver
1. With your computer turned off, ensure that your modem is connected properly, and then turn
on your computer. Upon booting up the computer should detect the modem and open
Welcome to the Found New Hardware Wizard screen. On this screen, select Install from
a list or specific location. Click Next.
2. On the Found New Hardware Wizard screen, check Search for the best driver in these
locations and Install from a specific location. Do Not click Next at this point.
3. Insert the MultiModem product CD into your CD-ROM drive, when the MultiModem main
screen appears, click Exit. Now, click Next on the Found New Hardware screen.
4. On the Found New Hardware Wizard screen, click on Search for the best driver in these
locations and Search removable media. Click Next. Windows installs the modem driver.
5. Click Finish to exit.

exit.
Using AT Commands
If you are comfortable using AT commands, you can use them to configure your modem. You
must enter these commands in your communication program's terminal window. You can use a
communication program such as PhoneTools. See Step 4 below.
How to Change the Country/Region Code
1. View the list of available country/region codes to find your country/region code by
executing the command AT +GCI? <CR>
Note: A list of country/region codes is also available on the Multi-Tech Web site at:
2. Set and save the code by executing the following command:
AT+GCI=nn <CR> (where nn is the country/region code).
3. OK displays.
4. The code then displays.
How to Verify the Code
Type AT+GCI?<CR>
or you can use this command:
ATI5<CR>
Example
1. Type AT+GCI=B5<CR> to set B5 as your country/region code.
2. Type AT+GCI?<CR> or ATI5<CR> to verify that B5 was set.
B5 indicates the configuration is set for any B5 country such as Canada and the
United States.

Chapter 2 – Installation
Step 4 - Install PhoneTools
Note: PhoneTools may or may not be included on the MultiModem II CD according to your company's
preference.
Data communications software gives you access to commands that govern how the modem operates;
that is, how the modem handles incoming and outgoing data streams, etc.
Multi-Tech includes a data communications software package (PhoneTools) on the product CD shipped
with your modem. In general, the modem will work with most data communications software packages.
1. Insert the MultiModem II CD into your CD-ROM drive. Allow Autorun to bring up the introductory
LCD.
2. Click on the PhoneTools icon and choose the appropriate language.
3. Follow the PhoneTools installation wizard. No input is needed. You may choose to view the
“Readme” file and whether or not to run PhoneTools immediately.
Windows 2000+ and XP Note: During installation, an advisory LCD may appear saying “FAX
capture driver installation” - this may cause a delay in the installation. This is normal. The
installation process has not failed or stalled. Simply wait a few moments until this LCD
disappears.
4. After installation, you can launch PhoneTools either from a desktop icon or from the Start |
Programs menu. Typically, it’s not necessary to reboot before using PhoneTools.

Chapter 4 – Leased Line Operation
Chapter 4 - Leased Line Operation
This chapter describes how to use the MultiModem II modem on a 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; 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. The modem also supports dial backup, which enables the modem to automatically switch to a
dial-up connection if the leased line goes down.
The modem supports both two-wire and four-wire leased-line operation.
Two-Wire / Four-Wire Setup
1. For leased line operation, plug one end of a two-wire phone cable into the modem’s LEASED
jack. Connect the other end to a leased line wall jack or terminals.
2. Turn on the modem.
3. Starting at the STATUS LCD, press the following buttons on the front panel: È, Æ, È, È, È,
Æ. The CURRENT SETTING= LCD appears.
4. If the CURRENT SETTING= LCD shows ASYNC AT, press ÇÅ and go to step 7. If it shows
anything else, press Æ to go to the ASYNC, NORM? LCD.
5. Press the Enter button to select normal asynchronous operation.
6. The OPTION SET LCD appears. Press ÇÅ to exit to the SYNC/ASYNC OPTIONS LCD.
7. Press ÇÅ, ÇÅ, ÇÅ, Æ, Æ, Æ, Æ. The 2 WIRE LEASE? ORIG LCD appears.
8. Choose one of two actions:
•
•
To set up the modem as the originate modem, press the Enter button.
To set up the modem as the answer modem, press Æ to display the 2 WIRE
LEASE? ANSWER LCD, and then press the Enter button.
Note: One of the modems in a leased line pair must be configured as the originate
modem, and the other as the answer modem, but it does not matter which is which.
9. The OPTION SET LCD appears. Press ÇÅ to exit to the ONLINE OPTIONS LCD, or Æ to
exit to the CURRENT SETTING= LCD to verify the selection.
10. This completes the setup for two-wire leased line operation. Upon completion, the modem
attempts to connect to the modem at the other end of the leased line. If the remote modem
has not yet been configured for leased line operation, you may turn off the local modem until
the remote one is ready.

jack on the back of the modem. Connect the other end of the cable to a four-wire leased line
jack or terminals.
2. Turn on the modem.
3. Starting at the STATUS LCD, press the following buttons on the front panel: È, Æ, È, È, È,
Æ, Æ, Æ, Æ. The SYNC, NORM? LCD appears.
4. Press the Enter button to select normal synchronous operation.
5. The OPTION SET LCD appears. Press ÇÅ to exit to the SYNC/ASYNC OPTIONS LCD.

To set up the modem as the answer modem, press Æ to display the
4 WIRE LEASE? ANSWER LCD, and then press the Enter button.
Note: One of the modems in a leased line pair must be configured as the originate
modem, and the other as the answer modem, but it does not matter which is which.
8. The OPTION SET LCD appears. Press ÇÅ to exit to the ONLINE OPTIONS LCD, or Æ to
exit to the CURRENT SETTING= LCD.
9. This completes the setup for four-wire leased line operation. Upon completion, the modem
attempts to connect to the modem at the other end of the leased line. If the remote modem
has not yet been configured for leased line operation, you may turn off the local modem until
the remote one is ready.
Dial Backup
For leased line operation, the MT5600BA-V92 modem has a dial backup capability in which the modem is
connected to a standard dial-up line as well as to the leased line. If the leased line fails, the originate
modem automatically dials and connects to the answer modem through the standard telephone network.
While it is in dial backup mode, the modem periodically checks the leased line to see if it is operational. If
the line is operational, the modem then attempts to restore the leased line. If the modem detects that it is
not connected to the standard telephone network when the leased line fails, it immediately switches to
leased line restore.
The dial-back timer, register S17, determines how long the modem waits after a leased line failure before
it attempts a dial backup connection. The S17 default setting is one minute. During that minute, the
originate modem tries to establish the leased line link. If the leased line is established during that time, the
S17 timer is cleared and everything is back to normal. If the timer expires, the modem attempts a dial
backup connection. The purpose of the timer for the answer modem is to determine when it can accept a
dial-up call. Dial-back starts only when both timers have expired and the leased line is still down.
The restore timer, register S15, determines how frequently restore attempts occur when the modems are
in dial backup mode. S15 can be set from 10 to 255 minutes in one minute increments. A value of 0
disables dial backup. The default value is 30 minutes.
Notes:
•
•
Register S15 must be set identically on the local and remote modems.
The dial backup number must be set from the front panel of the modem.

Chapter 5 – Remote Configuration
Chapter 5 - Remote Configuration
Remote configuration is a network management tool that allows you to configure modems anywhere in
your network from one location. With password-protected remote configuration, you can issue AT
commands to a remote MultiModem II modem for maintenance or troubleshooting as if you were on-site.
Basic Procedure
The following steps are valid regardless of whether the connection is established by the local or the
remote MultiModem II modem.
1. Establish a data connection with a remote MT5600BA-V92 modem.
2. Send three asterisks to initiate remote configuration. The remote modem responds:
Online Remote Access
Remote password:
3. Type the remote configuration password, and then press ENTER. The default is “MULTITECH.” It is
not case-sensitive.
•
If the password is incorrect, the word CONNECT appears, and the local modem is returned to
online mode.
•
If the password is correct, an >AT_ command prompt appears.
4. Type AT commands to configure the remote modem. It is not necessary to precede the commands
with “AT.”
5. When you have finished configuring the remote modem, type *E and press ENTER to exit remote
configuration mode and return to online data mode. You can now break the connection in the normal
way.
Note: The dialing command is not allowed in remote configuration mode.
Setup
Multi-Tech modems are shipped with a default setup password (MULTITECH). Because anyone who has
an owner’s manual knows the default setup password, for security you should change the password and
possibly also the remote configuration escape character.
Changing the Remote Configuration
Password
The remote configuration password can be changed only from the front panel of the modem:
1. Turn on the modem.
2. Starting at the STATUS LCD, press È È È Æ Æ È Æ to access the ENTER PASSWORD
LCD.
3. To change the password, press ÇÅ or È to select the first character of the password, and then
press Æ to go to the next character. Repeat until you have entered the entire password.
4. To cancel the new password, press Æ until the password is erased. To save the new
password, press the Enter button. The next time you remotely configure the modem you must
use the new password.

Chapter 5 – Remote Configuration
Changing the Remote Escape Character
To improve security, you can change a remote modem’s remote configuration escape character. The
remote configuration escape character is stored in register S13. The factory default is 42, which is the
ASCII code for the asterisk character (*). Setting S13 to 0 (zero) disables remote configuration entirely—
but 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 ATS13=n, where n is the ASCII code for the new remote configuration escape
character, and then press ENTER.
3. Save the new value by typing AT&W and pressing ENTER.
4. Type ATO<CR> to exit remote configuration.

Chapter 6 – Callback Security
Chapter 6 - Callback Security
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 the password is
invalid, the caller can try twice more before the modem hangs up. If the password is valid, the modem
hangs up and returns the call by dialing the phone number associated with the password.
It is possible to implement password protection without callback by storingahyphen (-) before the callback
phone number. The caller must then append a hyphen to his password to establish the direct connection.
The modem can store up to 30 callback phone numbers and 30 callback passwords. Phone numbers can
be up to 30 characters long and can contain the pause (,) and wait (W) characters in addition to the digits
and characters normally found on a touch-tone keypad. Passwords can be up to 10 characters long.
Callback phone numbers are associated with callback passwords by being assigned to the same callback
memory location. For example, if you assign the password “APRICOT” to memory location 16 and, in a
separate operation, also assign phone number 6127853000 to memory location 16, the modem
calls phone number 6127853000 when it receives the password “APRICOT.”
Because there is no way to examine the passwords and phone numbers stored in the modem, it is
important to write them down as you enter them. A form that you can print out for this purpose is provided
on the last page of this chapter.
Setup Procedures
Turning Callback Security On and Off
Autoanswer must be enabled (S0=1 or S0=2) for callback security to work.
AT Command Method
1. Open a terminal program, such as HyperTerminal.
2. In the terminal window, type one of the following commands:
•
•
To turn on callback security, type AT#DB1 and press ENTER. With remote callback
security turned on, each caller is asked to enter a password, then is disconnected
and called back by the modem. Also, dialing number locations 0–3, for use with the
DS=y dialing command, are replaced by callback dialing number locations 1–30.
To turn off callback security, type AT#DB0 and press ENTER. Callers no longer need
a password to connect to the modem, the modem is unable to call them back, and
stored dialing number locations 0–3 become available.

Chapter 6 – Callback Security
Calling Procedure
Use the following procedure to call a modem that has callback security enabled.
Autoanswer must be enabled on the calling modem (S0=1 or S0=2).
1. Using a data communication program such as HyperTerminal, dial the number of the callback
modem.
2. When the connection is established, the callback modem responds with a request for a
password.
3. Type the password for your modem, and then press ENTER. You have three attempts to enter
a valid password or be disconnected.
4. If the password is valid, the callback modem disconnects. Then, after a short delay, it calls
the number associated with the password and establishes a working connection.
Note: If you are calling a direct connect number, you must append a hyphen (-) to the
password. If the corresponding phone number has - as its first character, you will be able to
go directly online with the callback modem. If the corresponding phone number has no -
character, you will be prompted for a different password.
8. Press Æ, Æ to go to the ENTER NUMBER #2? LCD.
9. Repeat steps 3–7 to enter the next number.
10. Repeat as many times as necessary, up to memory location 30, until all numbers have been
entered.
Warning: There is no way to review an entry to confirm that it has been entered correctly. If you
attempt to look at a number entry by pressing the Enter button for an ENTER NUMBER #n?
LCD, it is possible for you to accidentally erase the entry.

Chapter 7 – Troubleshooting
Chapter 7 - Troubleshooting
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.
If you experience problems, please check the following possibilities before calling Technical Support.
None of the Indicators Light
When you turn on the modem, the LED indicators on the front panel should flash briefly as the modem
runs a self-test, and the liquid crystal display (LCD) should light. If the LEDs and LCD 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 transformer module is firmly connected to the modem and to the wall outlet or
power strip.
If the power strip is on and the modem switch is on, try moving the transformer module 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 transformer module may be defective. If you have another Multi-Tech modem, try
swapping modems. If the problem goes away, the first modem or transformer module may be
defective. Call Technical Support for assistance.
CAUTION: Do not under any circumstances replace the transformer module with one designed for
another product; doing so can damage the modem and void your warranty.

Chapter 7 – Troubleshooting
The Modem Does Not Respond to Commands
•
•
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.
•
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.
•
•
Try resetting your modem by turning it off and on.
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 the modem is connected
to. The serial cable might be plugged into the wrong connector—check your computer documen-
tation 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.
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, call Technical Support.
The Modem Cannot Connect When Dialing
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.
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.
Multi-Tech Systems, Inc. MT5600BA-V92 User Guide

Chapter 7 – Troubleshooting
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 (note, however, that X3 is
not allowed in some countries, such as France and Spain).
•
If the modem reports BUSY, the other number might be busy, in which case you should try again
later, or it might indicate that you have failed to add a 9, 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 95 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 com-
puter, 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.
The Modem Disconnects While Online
•
If you have Call Waiting on the same phone line as your modem, it can interrupt your connection
when someone tries to call you. If you have Call Waiting, disable it before each call. In most
telephone areas in North America, you can disable Call Waiting by preceding the telephone
number with *70 (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 Terminal, select Settings | Modem Commands. To change it
in 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.
If you were online, it 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.
The Modem Cannot Connect When Answering
•
The default DTR Control command (&D2) inhibits autoanswer. To enable autoanswer, change
DTR Control to &D0, and make sure &Q0, &Q1, &Q5, or &Q6 is also set. For more information,
see the &D command in the AT Command Reference Guide on the CD shipped with your
modem. For information on changing the modem’s default configuration, see “Step 3: Install and
Configure Your Software” in Chapter 2.
•
Autoanswer might be disabled. Turn on autoanswer in your datacomm program or send the
command ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.

Chapter 7 – Troubleshooting
File Transfer Is Slower Than It Should Be
•
You might have an older UART. For best throughput, install a 16550AFN UART or a Multi-Tech
ISI serial port card.
•
•
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.
Try entering the &V1 command to display information about the last connection, making a LCD
print of the connection statistics, and checking for parameters that might be unacceptable.
Data Is Being Lost
•
If you are using data compression and a high speed serial port, set the serial port baud rate to
four times the data rate.
•
Your UART might not be reliable at serial port speeds over 9600 bps or 19,200 bps. Turn off data
compression, reset your serial port speed to a lower rate, or replace your serial port with a faster
one.
•
•
Make sure the flow control method you selected in software matches the method selected in the
modem. If you are using the modem with a Macintosh, you might have the wrong cable for
hardware flow control.
Try entering the &V1 command to display information about the last connection, making a LCD
print of the connection statistics, and checking for parameters that might be unacceptable.
There Are Garbage Characters on the Monitor
•
Your computer and the remote computer might be set to different word lengths, stop bits, or
parities. If you have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your
communication software.
•
•
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 &V1 command to display information about the last connection, making a LCD
print of the connection statistics, and checking for parameters that might be unacceptable.
The Modem Doesn’t Work with Caller ID
•
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 B – Upgrading the Firmware
Appendix B - Upgrading the
Firmware
Introduction
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.
Upgrade Overview
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 at 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 for your modem.
4. Extract the firmware .HEX file and the appropriate flash upgrade program 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 upgrade program.
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, you can use
HyperTerminal.
2. In the program’s terminal window, type AT&F. Even if you cannot see the AT&F
command on your LCD, 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 ATI3, press Enter and record your results. The firmware version should appear
first in the response, which should look similar to the following:
ACF3_V1.702a_V90_P21_FSH
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.
II/firmware.asp.
2. Scroll down the table 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,” your modem has the current firmware version, and does
not need to be updated.
Multi-Tech Systems, Inc. MT5600BA-V92 User Guide
46
Download from Www.Somanuals.com. All Manuals Search And Download.
Appendix B – Upgrading the Firmware
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 II 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.
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\Multi-Tech 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&F command to
the modem to clear the stored parameters.
1. Run your favorite terminal program. If you are using Windows 2000+ / XP, you can use
HyperTerminal.
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 LCDs and sending them to your printer.
4. Type AT&F 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 boot code (e.g., F35ALOAD.S37) and the file name for the
new firmware (e.g., BKQG300G.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.

Appendix C – Installing a Modem Under Linux
Appendix C - Installing a Modem
Under Linux
Introduction
This appendix explains how to install a modem on a computer operating under the Red Hat Linux 6.2
operating system. Other versions of Red Hat and other Linux operating systems should be similar. Briefly,
in Linux, you do not need drivers for most standard external modems and most internal ISA bus modems.
Programs in Linux commonly call upon the port, rather than the modem.
Standard Linux Serial Port Definitions

Installation
Connect the external modem to an available serial port.
Setup
This section describes how to make sure Linux can talk to the modem and be able to dial up to the
Internet. Linux can use different programs and desktops depending on who made the Linux operating
system and what version it is. The following procedures use the most commonly installed components of
Red Hat 6.2. More information can be found in your Linux OS owner’s manual.
Using the Terminal Program Minicom to Verify Operation
1. At the command prompt, type minicom –s and press Enter.
2. Select Serial port setup and press Enter.
3. From Serial port setup, use the A key to access Serial Device, and then press Enter.
4. Press ESC.
5. You are now in the Minicom terminal. Type AT and press Enter. The LCD should display OK to
verify the operation. Alternately, dial a phone number to verify line operation
6. To leave Minicom, press CTRL + A, and then press Z.
7. On the help menu, press X to exit.
Using the Modem to Call the Internet
Linux allows different graphic user interfaces (GUI). In the following steps, we’ll use the Gnome Desktop
GUI and assume that the Internet Service Provider (ISP) you are calling assigns you the Domain Name
Service (DNS) and Internet Protocol (IP) addresses. For more information on DNS or IP, see the Linux
OS owner’s manual or contact your ISP.
1. On the Task Bar at the bottom of the LCD, select the Gnome Footprint.
2. Select Internet from the menu.
3. Select Dialup Configuration Tool.
4. Select Add, and then click Next.
5. Enter the connection name and phone number, and then click Next.
6. Enter your user name and password, and then click Next.
7. Select Normal ISP if your ISP is not listed, and then click Next.
8. Click Finish.

Appendix C – Installing a Modem Under Linux
Calling the ISP
1. On the Task Bar at the bottom of the LCD, select the Gnome Footprint.
2. Select Internet from the menu.
3. Select RH PPP Dialer.
4. Select the connection name you entered in step 5 of the previous section.
5. Click OK.
Answering Calls
To use the system for answering calls, Linux requires other programs to be installed, such as Mgetty,
Mgetty+Sendfax, and others, depending on your requirements. Each vendor of Linux has more than
adequate information on installing these programs.

importers to take-back electronics products at the end of their useful life. A sister Directive, ROHS
(Restriction of Hazardous Substances) complements the WEEE Directive by banning the presence of
specific hazardous substances in the products at the design phase. The WEEE Directive covers all
Multi-Tech products imported into the EU as of August 13, 2005. EU-based manufacturers,
distributors, retailers and importers are obliged to finance the costs of recovery from municipal
collection points, reuse, and recycling of specified percentages per the WEEE requirements.
Instructions for Disposal of WEEE by Users in the European Union
The symbol shown below is on the product or on its packaging, which indicates that this product must
not be disposed of with other waste. Instead, it is the user’s responsibility to dispose of their waste
equipment by handing it over to a designated collection point for the recycling of waste electrical and
electronic equipment. The separate collection and recycling of your waste equipment at the time of
disposal will help to conserve natural resources and ensure that it is recycled in a manner that
protects human health and the environment. For more information about where you can drop off your
waste equipment for recycling, please contact your local city office, your household waste disposal
service or where you purchased the product.
