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.
PHONE LINE LEASED
MultiModem II Connections
Connect the Modem to Your PC
Plug one end of the serial cable into the modem’s RS-232 connector.
Plug the other end into your PC’s serial port connector (COM1 or COM2).
Connect the Modem to the Telephone Line (Dialup
Connection)
Plug one end of the phone cable into the modem’s LINE jack.
Plug the other end into a public switched telephone network (PSTN) wall jack.
Important: The LINE jack and PHONE jack are not interchangeable. Do not plug the phone into
the LINE jack and do not plug the leased line cable into the PHONE jack.
Note: Regulatory agencies may impose certain restrictions on equipment connected to public
telephone systems.
Two-Wire or Four-Wire Leased Line Connection
Plug one end of a two-wire/four-wire phone cable into the modem’s LEASED jack.
Connect the other end to a leased line wall jack or terminals.
Modems with the leased line feature support dial backup.

Chapter 2 – Installation
Multi-Tech Systems, Inc. MT5600BA-V92 User Guide 9
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
Country or Region Codes
A list of country/region codes can be found on the Multi-Tech Web site at:
http://www.multitech.com/PRODUCTS/Info/approvals
Then click on global modems. The Global Modem Country Approvals page displays. On this page
you can view approvals, configuration strings and responses by country and products.
