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.

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+/XP, you must install the modem driver. The drivers are installed easily since
Windows supports Plug-and-Play.
Installing the Modem Driver
1. Make sure your modem is connected properly, and then turn on your computer. Windows
should detect your new modem and open the Install New Modem wizard.
Note: If Windows cannot find a modem, your modem may be turned off, it may be plugged
into the wrong connector on your computer, or the serial cable may be faulty. See “None of
the LEDs Light When the Modem Is Turned On” and “The Modem Does Not Respond to
Commands” in the “Troubleshooting” chapter.
2. Insert the MultiModem II CD into your CD-ROM drive, and then click OK.
3. Windows installs and configures the modem.
4. Click Finish to exit.

Step 3 - Setting Your Country or Region Code
The MT5600BA-V92 modem is a global modem - it can be used all over the world.
However, countries or regions vary in their requirements for how a modem functions. Therefore, you must
configure yours to match the defaults of the country or region in which you are using it. Choose from any
of the three methods:
•Using the LCD Panel to Set Your Country or Region Code
•Using the Global Wizard to Set Your Country or Region Code
•Using AT Commands to Set Your Country or Region Code
Using the LCD Panel

1. Insert the MultiModem II CD into the CD-ROM drive. The Autorun dialog box appears.
2. Click Initial Setup and Country or Region Selection. The Global Wizard dialog box
appears. Click Next.
3. The Global Wizard searches for your modem and identifies it. Click Next after your
modem is identified.
4. Select the country or region in which the modem will be used. Click Next.
5. Review your choice. If it is correct, click Next to configure the modem.
6. When the Global Wizard announces that the parameters have been set, click Finish to
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:
http://www.multitech.com/PRODUCTS/Info/approvals
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
Multi-Tech Systems, Inc. MT5600BA-V92 User Guide 12
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 3 – Using the Front Panel
Multi-Tech Systems, Inc. MT5600BA-V92 User Guide 13
Chapter 3 - Using the Front Panel
Like any modem, your Multi-Tech modem operates only under the control of a communication program,
such as the PhoneTools program included with the modem. It also operates under other general-purpose
data communication programs, such as Windows Terminal and HyperTerminal. For information on how to
use the modem with the communication program of your choice, please refer to the program’s
documentation.
Modem Configuration
Your modem normally is configured through Windows or through the communication program you are
using. The default settings work best for most purposes. See “Step 4: Install PhoneTools” in Chapter 2 for
help in setting up your communication program.
You also can configure your modem either through the front panel or by sending AT commands to the
modem. The AT commands can be found in the AT Reference Guide on the CD shipped with this
modem.
Front panel
LED Indicators
The MT5600BA-V92 has six LED indicators on the front panel that indicate status and activity:
Receive Data The RD indicator flashes when the modem is receiving data.
Transmit Data The TD indicator flashes when the modem is transmitting data.
Carrier Detect The CD indicator 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.
Off-Hook The OH indicator lights when the modem is off-hook, which occurs when the
modem is dialing, online, or answering a call. The LED flashes when the modem
pulse-dials.
Terminal Ready The TR indicator lights when a communication program is using the
modem. It means the modem is ready for an outgoing or incoming call. It goes off
when the communication program disconnects the serial port. When it goes off, a
connected modem will disconnect.
Test Mode The TM indicator lights when the modem is in test mode.
