Chapter 1 - Introduction and Description

Congratulations

Congratulations on your purchase of one of the finest internal

data/fax/voice modems available today: the MultiModemZPX

™

from Multi-Tech Systems.

The MultiModemZPX is an internal, half-length, fax modem card

that can be plugged into any 16-bit ISA expansion slot.

Your MultiModemZDX incorporates a new modem technology

called

K56flex

, that enables Internet connections at data rates up to 56K bps over standard telephone lines. K56flex technology is able to propel data downstream from the Internet to your computer at speeds of up to 56K bps because data is digitally encoded instead of modulated. Upstream transmission, mostly keystroke and mouse commands from your computer to the central site, continue to flow at the conventional data rate of

33.6K bps. Your MultiModemZPX offers interactive automatic dialing, as

well as command mode option configuration. You may store two command line/telephone numbers, of up to 40 characters each, in the modem’s nonvolatile memory. The modem pulse or tone dials, and recognizes dial tones and busy signals for reliable call-progress detection. The modem can detect AT&T calling card tones. It is FCC-Registered for connection to telephone networks without any Data Access Arrangements (DAA’s).

This owner’s manual will help you to install, configure, use, and troubleshoot your modem.

* Though this modem is capable of 56K bps download performance, line impairments, public telephone infrastructure and other external technological factors currently prevent maximum 56K bps connections.

Installation

Installation of the MultiModemZPX consists of four steps: (1) Configuration of the modem’s DIP-Switch and Jumper settings, (2) installation of the modem in the computer; (3) connection of the modem to the telephone line and, optionally, to an external speaker and microphone; and (4) installation of the modem’s drivers.

Note: Unless otherwise noted, these procedures are for both PnP and non-PnP environments.

Owner’s Manual

Configure the MultiModemZPX DIP-Switches and Jumpers

Windows 95 Plug and Play

Unlike an external modem, the MultiModemZPX contains its own serial port. When Windows 95 detects the MultiModemZPX, it assigns the next available COM port number to it. Since COM1 and COM2 are standard serial ports in Windows computers, Windows 95 typically assigns COM3 to the MultiModemZPX’s serial port. Windows 95 also assigns the MultiModemZPX a port address and interrupt request (IRQ) number. Because the number of IRQs is limited, a computer with several accessories may not have an available IRQ for your new modem. In that case, you may have to decide which of your other accessories you can modify or do without.

Non PnP

The MultiModemZPX is equipped with a 4-position DIP-Switch and 9 Berg Jumpers for easy configuration for Windows Plug and PlayTM (PnP) environments as well as non-PnP enivironments. The factory default configuration is set up for PnP, but if you wish a different configuration, refer to the following chart for further information. If you have MS-DOS 6.0 or later, you can find your current COM Port settings from a diagnostic program called prompt. After the opening screen, select COM Ports. You will be shown a list of current device Port Addresses, and will be able to determine available COM Ports. Be sure that all settings are correct before proceeding with the installation.

Sound Card Considerations

If you want speakerphone functions along with the ability to record sound or .WAV files through the sound card at the same time, you need:

• two stereo PC microphones

• one stereo male-to-male patch cord

• one sound card and optional speakers

To connect a 3rd party sound card, perform the following steps:

1. Obtain a stereo male-to-male patch cord (can be purchased

at a local PC retail store).

2. Place one end of a stereo male-to-male patch cord into the

“LINE OUT” jack of the MultiModemZPX and the other end into the “LINE IN “ jack of the sound card. This lets you to hear the activity of the modem whether it is originating or answering a call or playing a recorded message using the bundled Trio software.

3. Place the two stereo microphones (do not use mono

microphones) far enough apart from each other to eliminate feedback (e.g., one on each side of the monitor). Feedback will only occur if the microphones are too close to each other. Make sure speakers are amplified with power source being either a battery or AC outlet.

4. Place the microphone and speakers far enough apart from

each other to eliminate feedback. Plug the connector of both microphones into the “MIC IN” jack of both the SoundCard and the MultiModemZPX.

Install the MultiModemZPX into the Computer

Installation of the MultiModemZPX requires you to open your computer. Please consult the computer manual in addition to the following instructions:

1. Turn off the computer and unplug it. Failure to do so may result in damage to both the MultiModemZPX and the computer. Do not turn the computer on until the instructions tell you to do so.

2. Remove the cover from the computer as instructed in the computer manual.

3. Select an empty 16-bit half- or full-size ISA expansion slot. Remove the expansion slot cover and save the retaining screw.

4. Before handling the MultiModemZPX, discharge any static in your body by touching a piece of grounded metal such as a water faucet. Carefully remove the MultiModemZPX from its anti-static bag, handling it only by the mounting bracket and edges. Do not touch the gold-plated connectors along the bottom edge.

5. Placing the MultiModemZPX directly above the expansion slot, gently but firmly push it into the connector until the card’s retaining bracket is flush against the computer chassis.

6. With the screw you saved in step 3, fasten the retaining bracket to the computer chassis.

7. Replace the cover of the computer.

Is Your MultiModemZPX Ready for Use?

If you’re an experienced modem user, you may simply want to check your modem’s settings for data compression, error correction, and so on. You may find that you can get moving quite quickly if you just issue the command lists how your modem is currently configured, the stored (user) profiles, and the first four stored telephone numbers. If you come across a setting you’re unsure of, refer to Chapter 3 of this manual for AT command and S-Register explanations and defaults.

If you’re a novice, please continue to the next sections of this chapter.

Operating Your MultiModemZPX

You control your MultiModemZPX by issuing AT commands and setting S-Registers. Right now your MultiModemZPX is set up for the most typical user application, that is, as a traditional modem set to make a dial-up call to a remote installation where the call is answered automatically; therefore, you shouldn’t need to change the current default configuration. (If however, you know that your application does not follow this profile, please refer to Chapter 3 for AT Commands and S-Registers.)

In operating your MultiModemZPX it is likely that you will use your data communications software to either:

• enter “terminal” mode, where you can “speak most directly”

to the modem by issuing AT commands, or to

• launch a datacomm session through a set of modem

configurations which you select and then associate with a target telephone number. Once you have created, saved, and named this set of information according to your connection needs and your datacomm software’s conventions, the software then simplifies your dialing because you needn’t reconfigure your modem, nor run the risk of mistakenly keying-in incorrect information.

Either way, you need to understand that an AT command is the method by which your modem is controlled, and must therefore prefix nearly all commands. AT stands for attention, and alerts the modem that a command follows. You may enter these commands with either upper- or lower-case characters. Once you’re in terminal mode, enter AT followed by <CR> to check whether your modem is operational. If everything’s fine, your modem will respond OK.

MT5634ZPX

Page 24

Owner’s Manual

Simple Operations

You can dial by using the ATD command and the phone number of the modem with which you wish to connect, e.g., ATD6127853500. Your modem will dial the number; a “scrambling” noise is heard as the modem negotiates the kind of connection it can make, and once the modems have settled on a common connection, a connect message on your computer’s video is displayed. To hang up a call, enter ATH0<CR>. Your modem will return on hook. Your video now displays OK, signifying that your modem is ready for your next command.

Software Configuration

Communications software must be configured to work with the MultiModemZPX, your computer, and the remote system it is calling. Fortunately, most communications programs make the process easy by providing a default initialization string to your modem as well as defaults for most of the other required parameters. Some software programs allow you to select your modem type from a menu. By this method, initialization strings that correspond to a particular modem type can be selected to operate optimally with the software it is utilizing.

*: Refer to your respective software manual for further information on your communications software.

Other software programs require you enter an initialization string in the software modem setup screen. If this is the requirement in your software application, enter the following command string to initialize your modem: modem to operate optimally with the software it is utilizing.

Testing the MultiModemZPX’s Voice Function

There are several tests you can perform to verify the MultiModemZPX’s voice circuits. Try the answering machine test first; if that doesn’t work, and you have a microphone and speaker connected to the MultiModemZPX, try the loopback and speakerphone tests, which can test the modem’s voice circuits without special software.

MultiModemZPX’s Answering Machine Test

Test the MultiModemZPX’s voice function by using the included software to set up the MultiModemZPX as a telephone answering machine. Have a friend call and leave a message, then play it back.

Loopback Testing

Windows 95 Plug and Play

1. Connect a microphone and speaker to the MultiModemZPX. To avoid feedback, make sure the microphone and speaker are well separated; for best results, use a headphone instead of a speaker.

2. Select

3. Double-click on the Multi-Tech BBS icon you created in “Step 2: Call the Multi-Tech BBS.” HyperTerminal starts with the Connect dialog box open.

4. Click Cancel in the Connect dialog box.

5. In the HyperTerminal terminal window, type AT&&S and press ENTER. This command causes input from the microphone to be looped back to the speaker.

6. Speak into the microphone; you should hear your voice on the speaker or headphone.

7. Type ATZ and press ENTER to reset the modem.

Configuring Communications Software

Communications software must be customized, or make it work with your computer’s serial port and modem, to meet the requirements of the system on the other end of a connection, and to meet your own requirements.

Windows 95® makes configuration easy for Windows 95– compliant communications software. The modem and port are, for the most part, configured automatically when the modem’s drivers are installed in Windows. The communications software then uses the Windows 95–supplied configuration when it dials out.

However, non-PnP systems as well as “legacy” programs— those designed for earlier operating systems(non-PnP)—must be configured individually.

This chapter will help you make configuration choices specific to the MultiModemZPX. For help with other configuration choices, please refer to the software’s manual or online Help. Generally, your best course is to accept the software’s default values.

1. Turn on your computer and run your communications software.

2. Find the dialog box or menu that lets you specify your modem. (In HyperTerminal, select File, Properties, Phone Number; in ProComm Plus for Windows, select Window, Setup, Advanced; and in MultiExpress Terminal for Windows, select Setup, Terminal, Modem.)

configured

, to

3. If you are using legacy software, or if you have more than one modem installed, choose the appropriate model number for the MultiModemZPX (e.g., Multi-Tech MT5634ZPX ) from the software’s modem list. If your model number isn’t listed, choose a generic modem of the same speed as yours, i.e., a generic V.34 or 33600 bps modem, and rename it “MultiTech MT5634ZPX”.

MT5634ZPX

Page 32

Owner’s Manual

4. If your legacy software doesn’t have the correct modem initialization string, you must change it. AT&F^M, which selects the modem’s factory default settings, works well for most connections. (^M is the code for the carriage return character that sends the string to the modem.) If you need extra time to make a connection, add S7=60 to the string, like this: AT&FS7=60^M. For CompuServe, the initialization string should be AT&F\N0^M. If you use CompuServe’s WinCIM software, change the initialization string to AT&F\N0\Q1^M for compatibility with WinCIM’s software flow control. Change the error correction string to \N7%C0, and the data compression string to \N7%C1. If you want the modem to always answer the phone, add S0=1 to the initialization string.

*: To change the modem’s default initialization string, type the new

commands in the software’s terminal window, adding the command

to store the new commands in the modem’s nonvolatile memory;

e.g., AT&FS0=1&W. You can then simplify your initialization string to ATZ^M.

5. If you are using legacy software, select the port the modem is connected to (normally, COM3).

6. For maximum throughput when using data compression, set the serial port baud rate, or DTE rate, to 115,200 bps. (In Windows 95, select Start, Settings, Control Panel, Modems, Properties.)

7. If your legacy software has an autobaud selection, make sure it is disabled. Autobaud is for much older modems, and can cause problems if enabled.

8. If the software allows you to edit the no-connect messages (

NO CARRIER, BUSY, NO ANSWER, NO DIALTONE

make sure there is no space between

NO DIALTONE

DIAL

and

TONE

MT5634ZPX

9. If you must dial 9 to get an outside line, edit the dialing prefix to include a 9 and a comma, e.g., ATDT9, (the comma inserts a pause before dialing the next digit). Similarly, to turn off call waiting for the duration of the call, insert the disabling code used in your area, e.g., ATDT*70,. If you are using Windows 95-compliant software, make these changes in the “How I dial from this location” box of the Dialing Properties sheet.

*: *70 is only used in the United States.

Chapter 4 - Troubleshooting

Introduction

This chapter covers some common problems you may run into with your modem and how to solve them. Your MultiModemZPX 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. Always begin with the initial checklist to make sure all hardware is properly connected. Then review the common problems for recommendations on what to change.

Initial Checklist

Always begin with the following checklist to make sure all hardware is properly connected and that the modem is set up properly.

• Make sure you are running the Microsoft Windows 95 operating system. This modem will not run properly with other operating systems.

• Make sure the COM port you chose during setup matches the COM port set in your communications software. See Chapters 2 and 3.

• Check that the phone cord between the modem’s “LINE” jack and the wall jack is undamaged and firmly connected to both.

• If you connected a telephone to your modem, check that the phone cord between the modem’s “PHONE” jack and the telephone is undamaged and firmly connected to both.

• If you connected a microphone to your modem, check the connection of the microphone plug to the modem’s “MIC IN” jack.

MT5634ZPX

Page 53

4 Troubleshooting

• If you connected speakers to your modem, check the

connection of the speaker plug to the modem’s “LINE OUT” jack.

• Retry whatever action was not working.

• If it still does not work, check the following section for a

description and possible solution of your problem.

• If you do not find your problem listed in the next section, see

Chapter 7 for information on how to reach one of our technical support technicians via our toll-free telephone number, the Internet, or CompuServe. Don’t forget to fill out the information in “Recording Modem Information” in Chapter 7 before contacting a technical support technician.

Common Problems

You may encounter the following problems:

• The modem does not respond to commands.

• The modem dials but is unable to make a connection.

• The modem disconnects while online.

• The modem cannot connect when answering.

• File transfer appears slower than it should be.

• Data is being lost.

• There are garbage characters on the monitor.

• Fax and communications software won’t run at the same

time.

If you experience problems, please check the following possibilities before calling Technical Support (see Chapter 7).

MT5634ZPX

Page 54

Owner’s Manual

The Modem Does Not Respond to Commands

• Make sure you are in terminal mode in your data

communications program, then type AT and press ENTER. If you get an OK response, your connections are good and the problem likely is in the connection description in your communications software.

• Try resetting your modem by sending it an command in terminal mode. If you are using legacy software— software designed for an older operating system—make sure the initialization string includes &F as the first command, to cancel any “leftover” commands that could interfere with the modem’s operation.

• If you don’t get an OK, the problem may still be in the communications software. Make sure you have done whatever is necessary in your software to make a port connection. Most legacy (prior to Windows 95) communications programs connect to the COM port when the software loads, and remain connected until the program terminates. Some, however, can disconnect without exiting the program; if you have one of these, try issuing the software’s connection command. Also, if more than one communications program is open, they can conflict with each other. Make sure all other communications programs are closed, and then try again.

• If you are using legacy software, its COM port setting may not match the COM port Windows 95 assigned to the modem. Compare the COM port setting in your software to the COM port reported in the Diagnostics tab of the Modems Properties sheet. (Select Start, Settings, Control Panel, Modems, Diagnostics.)

• Another expansion card, such as a bus mouse or sound card, might be using the same COM port, memory address, or interrupt request (IRQ) as your modem. On the Windows 95 desktop, right-click on My Computer, select Properties,

ATZ

AT&F

Device Manager, and Ports, then double-click on the Communications Port your modem is connected to. In the port’s Properties sheet, click on the Resources tab to see the port’s Input/Output range and Interrupt Request. If another device is using the same address range or IRQ, it will appear in the Conflicting Device List. Uncheck Use Automatic Settings to change the port’s settings so they do not conflict with the other device, or select the port the conflicting device is on and change it instead. If you need to change switches or jumpers on the conflicting device; refer to the device’s documentation.

• The modem may be defective. If you have another

MultiModemZPX, try swapping modems. If the problem goes away, the first modem is possibly defective. Call Technical Support for assistance (see Chapter 7).

The Modem Dials But Cannot Make a Connection

There can be several reasons the MultiModemZPX 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. If you have disabled the modem’s extended result codes, re-enable them by entering ATV1X4 in the terminal window and pressing ENTER. When you dial again, the modem will report the call’s progress.

• If the modem reports 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 may 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 may be installed behind a company phone system (PBX) with an internal dial tone that sounds different from the normal dial tone. In that case, the modem may not recognize the dial tone and may 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 include 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.)

NO DIALTONE

, check that the

MT5634ZPX

• If the modem reports BUSY, the other number may be busy,

in which case you should try again later, or it may 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 using legacy software 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. For example, to change the dial prefix in MultiExpress Terminal, select Setup, Modem; then select the modem type you are using and type the new prefix in the Dial Prefix box. To change it for Windows 95 software, select Start, Settings, Control Panel, Modems. In the Modems Properties sheet, select the appropriate MultiModemZPX model number (e.g., Multi-Tech MT5634ZPX), click Dialing Properties, and type 9 in the local and long distance boxes in the “How I dial from this location” box.

• If the modem reports

NO ANSWER

, the other system has failed to answer, 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 may be having problems negotiating because of modem incompatibilities or line noise. Try connecting at a lower speed by setting register S37 to a lower rate (e.g., by typing ATS37=11 in the terminal window and pressing ENTER) and then calling again.

MT5634ZPX

Page 58

Owner’s Manual

The Modem Disconnects While Online

• If you have call waiting on the same phone line as your

modem, it may 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 telephone number is dialed). For example, to change the dial prefix in MultiExpress Terminal, select Setup, Modem; then select the modem type you are using, and type the new prefix in the Dial Prefix box. To change it for Windows 95 software, select Start, Settings, Control Panel, Modems. In the Modems Properties sheet, select the Multi-Tech MT5634ZPX, click Dialing Properties, check “This location has call waiting,” and select the correct code for your phone service.

Note: *70 is only used in the United States.

• 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 telephone jack.

• You may have a poor connection because of line conditions or the problem may have originated on the other end of the line. Try again.

• If you were online with a BBS or a commercial online service, it may 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.

MT5634ZPX

Page 59

4 Troubleshooting

The Modem Cannot Connect When Answering

• Auto-answer may be disabled. Turn on auto-answer in your

data communications program or send the command

ATS0=1

to your modem in terminal mode.

File Transfer Appears Slower Than It Should Be

• If you are using a slow transfer protocol, such as Xmodem

or Kermit, 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.

Data Is Being Lost

• If you are using data compression, be sure the serial port

baud rate is set to a minimum of four times the data rate.

• Make sure the flow control method you selected in software

matches the method selected in the modem. If you are using CompuServe’s WinCIM software, you must set the modem for XON/OFF flow control (see Chapter 4 for the CompuServe initialization string).

• Try entering the &V (View Parameters) command, making a

screen print of the diagnostics listing, and checking for parameters that may be unacceptable.

MT5634ZPX

Page 60

Owner’s Manual

There Are Garbage Characters on the Monitor

• Your computer and the remote computer may 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 communications software.

• You may be experiencing line noise. Enable error correction, if it is disabled, or hang up and call again; you may get a better connection.

• 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 &V (View Parameters) command, making a screen print of the diagnostics listing, and checking for parameters that may be unacceptable.

Fax and Data Software Won’t Run at the Same Time

• Although you can have Windows 95-compliant data and fax

communication applications open at the same time, they cannot use the same modem at the same time. Make sure no other application is online when you try to dial out. If you are using legacy communications software with Windows 95, you may get a message that another application is occupying the device even when no call is in progress. Close any open legacy communications programs, and try again.
