2 Installation Chapter 2: Installation 5
2 Installation Introduction This chapter shows you step-by-step how to set up your Multi-Tech modem, test it, and make your first calls. What You Will Need Before starting, make sure you have everything you will need.
2 Installation Connecting the Modem to Your System Connections for the MT5600ZDX Turn off your computer. Placing the modem in a convenient location, connect it to your computer’s serial port, to the phone line, to AC power, and to your phone. PWR RS232 PHONE LINE Figure 2–1. MT5600ZDX Connections. 1.
2 Installation 3. (Optional) Connect the Modem to the Phone For voice-only calls, plug a phone into the modem’s PHONE jack. 4. Connect the Modem to the AC Power Outlet Plug the DC power transformer into an AC power outlet or power strip. Plug the DC power transformer into the POWER jack on the modem. Note: Use only the DC power transformer supplied with the modem. Use of any other transformer voids the warranty and can damage the modem.
2 Installation Connections for the MT5600ZDXV PWR RS232 PHONE LINE Figure 2–2. MT5600ZDXV Connections 1. Follow All of the Connection Directions for the MT5600ZDX The add these steps: 2. Connect the Microphone 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 1/8inch mini plug. Do not use a monophonic microphone. 3.
2 Installation Installing the Modem Driver If you use Windows 95/98/2000 or Windows NT 4.0, you must install the modem driver. The modem driver is used by Windows to control the modem. If you use Windows 3.1 or another operating system, skip this step and go to Chapter 3. If you are using a Linux operating system, see Appendix F. 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.
2 Installation Installing Your Data Communications Software Data communications software is designed to send and receive messages. MultiTech includes a data communications program with your modem. However, the modem will work with any data communications software. To install the data communications software provided with this modem, insert the CD into the CDROM drive. The software will then install automatically if you have Windows 95/ 98/2000 or Windows NT 4.0.
2 Installation Dial-Up Networking Whether you use the Internet for e-mail or browsing the Web, to connect to it through your modem, you must first set up a dial-up networking program. The one in Windows 95, 98, 2000, and Windows NT 4.0 is called Dial-Up Networking. Dial-Up Networking establishes your connection to the ISP’s server, which is the shared computer that manages calls from clients (your computer) to the Internet.
2 Installation Installing Dial-Up Networking in Windows 2000 Dial-Up Networking installs automatically in Windows 2000. The following instructions describe Dial-Up Networking connection options under Windows 2000, and guide you in setting up a Dial-Up Networking connection to an Internet service provider (ISP). Note: Make sure TCP/IP is installed on your computer. 1. To set up a Dial-Up Networking connection in Windows 2000, select Start | Settings | Network and Dial-up Connections. 2.
2 Installation 12. When the Completing the Internet Connection Wizard appears, click Finish. For further information on Dial-Up Networking, see Windows 2000 Help. Installing Dial-Up Networking in Windows NT 4.0 To install Dial-Up Networking 1. Double-click the My Computer icon, and then double-click the Dial-Up Networking icon. If Dial-Up Networking is not installed, you will see an Install button in the Dial-Up Networking dialog box. 2. Insert the Windows NT 4.0 compact disc into the CD-ROM drive. 3.
2 Installation Sending a Fax With your data communications software, you can use your modem to send and receive faxes directly from your computer. The following steps show you how to fax a document directly from a Windows application without opening the data communications program. 1. Create a document in a Windows application, such as Word, a graphics editor, or a spreadsheet. Keep the application and the document open, and select Print from the File menu. 2.
2 Installation 56 56K Mode (56,000–28,000 bps) Lights whenever the modem is set for or connects using either the K56flex or the V.90 protocol. The actual connection speed depends on the ISP server capabilities and line conditions. 28 V.34 Mode Lights when the modem in connected in V.34 mode. 14 V.32 bis Lights when the modem is connected in V.32 bis mode. OH Off-Hook Lights when the modem is off-hook, which occurs when the modem is dialing, online, or answering a call.
3 Advanced Options Chapter 3: Advanced Options 17
3 Advanced Options Introduction Like any modem, your Multi-Tech modem operates only under the control of a communications program, such as the communications 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 communications program of your choice, please refer to the documentation provided with the data communications program.
3 Advanced Options 5. Select the port the modem is connected to (normally COM1 or COM2). 6. Select your serial port speed. This can be labeled “maximum speed,” “DTE bps,” or “baud rate.” Ideally, if you use data compression, you should set your serial port baud rate to four times the modem’s maximum transmission speed or faster; however, few files can be compressed enough to require speeds that high, and not all serial ports can handle speeds that high.

5 Troubleshooting Chapter 5: Troubleshooting 47
5 Troubleshooting Introduction 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, check the list of troubleshooting procedures before calling Multi-Tech. • None of the LEDs light when the modem is on. • The modem does not respond to commands. • The modem dials but is unable to make a connection. • The modem disconnects while online.
5 Troubleshooting The Modem Does Not Respond to Commands 4 Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”) 4 Make sure you are issuing the modem commands from the data communications program, either manually in terminal mode or automatically by configuring the software. (You cannot send commands to the modem from the DOS prompt.) 4 Make sure you are in terminal mode in your data communications program, then type AT and press ENTER.
5 Troubleshooting To change a port address or IRQ in Windows 3.1x, double-click the Control Panel icon, then the Ports icon. Click on the port you want to change, click Settings, click Advanced, and select the new port address and/or interrupt. If you wish to use COM3 or COM4, note that COM3 shares an IRQ with COM1, as does COM4 with COM2, so you should change their IRQs to unused ones, if possible.
5 Troubleshooting installation, plug a phone into your modem’s phone 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.
5 Troubleshooting 4 Check for loose connections between the modem and the computer, the phone jack, and AC power. 4 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. 4 If you were online with a BBS or an online service like CompuServe, 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.
5 Troubleshooting Data Is Being Lost 4 If you are using data compression and a high speed serial port, set the serial port baud rate to four times the data rate. 4 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. 4 Make sure the flow control method you selected in software matches the method selected in the modem.
5 Troubleshooting Fax and Data Software Can’t Run at the Same Time 4 Communication devices can be accessed by only one application at a time. Under DOS or Windows 3.1x, you can run either your fax software or your data communications program, but not both at the same time, unless you have a special communication device management application. In Windows 95, 98, and NT 4.0, you can have data and fax communication programs open at the same time, but they cannot use the same modem at the same time.
A Regulatory Compliance Appendixes 55
A Regulatory Compliance Appendix A: Regulatory Compliance Note: Each regulation may not apply to every version of the MultiModemZDX. FCC Part 15 This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
A Regulatory Compliance FCC Part 68 Telecom 1. This equipment complies with part 68 of the Federal Communications Commission Rules. On the outside surface of this equipment is a label that contains, among other information, the FCC registration number. This information must be provided to the telephone company. 2. The suitable USOC jack (Universal Service Order Code connecting arrangement) for this equipment is shown below.
A Regulatory Compliance Fax Branding Statement The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other electronic device, including fax machines, to send any message unless such message clearly contains the following information: • Date and time the message is sent • Identification of the business or other entity, or other individual sending the message • Telephone number of the sending machine or such business, other entity, or individual This information
A Regulatory Compliance International Modem Restrictions Some dialing and answering defaults and restrictions may vary for international modems. Changing settings may cause a modem to become non-compliant with national telecom requirements in specific countries. Also note that some software packages may have features or lack restrictions that may cause the modem to become non-compliant.
A Regulatory Compliance Use of pulse dialing, when this equipment is connected to the same line as other equipment, may give rise to ‘bell tinkle’ or noise and may also cause a false answer condition. Should such problems occur, the user should not contact the Telecom Faults Service. The preferred method of dialing is to use DTMF tones, as this is faster than pulse (decadic) dialing and is readily available on almost all New Zealand telephone exchanges. 5.

C Loopback Tests Appendix C: Loopback Tests Introduction Each time you turn on your modem, it performs an automatic self-test to ensure proper operation. Your modem also has three diagnostic tests: local analog loopback, remote digital loopback, and local digital loopback. These ITU-T V.54 loopback tests isolate telephone circuit and transmission problems. In a loopback test, data from your computer loops through the circuits of your modem and/or a remote modem before it appears on your monitor.
C Loopback Tests Test Procedure 1. Connect the modem to your computer. Using your communication program, set the desired baud rate and go into terminal mode. 2. Type AT and press ENTER; you should get an OK message. Type AT\N and press ENTER to disable error correction. 3. Type AT&T1 and press ENTER. This places your modem in analog loopback mode in the originate mode. A CONNECT message should appear on your display. The modem is now out of command mode and in a pseudo-online mode. 4.
C Loopback Tests Test Procedure 1. Arrange to have &T4 set on the remote test modem. This command enables the remote modem to respond to an &T6 request for a remote digital loopback test from the local modem. 2. Open your communications software and go into terminal mode. Type AT and press ENTER; you should get an OK message. Type AT\N and press ENTER to disable error correction. Type AT+MS=9,1,9600,9600 and press Enter to set the local modem to V.32 mode at 9600 bps. 3.

E Upgrading the Modem Appendix E: Upgrading the Modem 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.
E Upgrading the Modem 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/ MultiModemZDX/firmware.asp. 2. Scroll down the table to your modem model number. 3. Look at the firmware version number for your modem. 4.
