Introduction

Models 33.6ifxC Data/Fax, 33.6ifxvC Data/Fax/Voice, and 33.6ifxspC Speakerphone Modems

Thank you for purchasing this high-speed modem. These modems are among the fastest now available. When you use your new modem, connection time will be quicker, response time will be faster, and it will take less time to transfer files. If you haven’t used a modem before, you’ll soon appreciate the features they offer.

After you install the modem and its communications software, connect it to a telephone line and you’re ready to dial up other systems, surf the internet, or send and/or receive faxes.

Other Particulars:

· Your new data/fax modem operates at extremely high speeds: up to 33,600 bps for data communications and 14,400 bps for faxing. (With data compression activated, it has a throughput rate of up to 115,200 bps). See Specifications at rear of manual.

· Because it conforms to Hayes-Smart, Bell, and CCITT (ITU) standards, this modem is also guaranteed to communicate with other modem/fax devices that operate at the s ame or slower speeds. Standard faxing conventions are also supported, and basic AT modem commands with S Registers are available.

· Other important features include: Auto dial & answer, speed buffering/flow control, self-testing of power/analog/digital signals, Non Volatile RAM to preserve four phone numbers & AT command profiles, and a parallel 16550 UART interface.

The modem is reliable and easy to install. It is ready for use on plug and play systems, but its factory defaults can be easily modified for use on ISA direct (non-plug and play) systems. It will also provide years of trouble free operation.

Note: All necessary cabling is included in your package. A popular communications software application with a Graphical User Interface (GUI) is also supplied. This software will simplify faxing and modem use.

Hardware Installation

This 33,600ifx high-speed internal modem is a half-card modem device designed for installation in IBM and compatible personal computers. The modem will function on DOS/Windows 3.1, Windows 95 or Windows NT based systems, or on computers that use the OS/2, UNIX, and LINUX operating systems.

The data/fax and data/fax/voice models are similar in appearance (see illustration below). Each is designed to be mounted on an 16-bit expansion slot inside the computer.

The brackets of some 33.6Kbps data/fax modem cards may contain extra jacks. These jacks are inoperative for data/fax or data/fax/voice model modems.

Plug and Play Factory Defaults
A plug and play system is defined as a Windows 95/Pentium 75 (or better) computer with a BIOS labeled plug and play. If you have such as system, you should be able to install the modem without changing the factory default settings. (For Plug & Play systems, jumper blocks are installed on jumpers 1 through 10.) 

Note: If you plan on using the modem in the DOS environment, as well as in Windows 95, you will have to treat the card as if you were installing it in a non-plug and play system

Resetting Jumpers (Non-Plug and Play Systems)

If you have a non-plug and play system (i.e., a Windows 3.x, Windows NT, or Windows 95 system not equipped with a Pentium 75 processor and a plug and play BIOS), you must reset the factory jumpers on the modem card to reflect a specific COM port and IRQ setting. The COM port and IRQ that you specify must not now be in use by another device.

The Modem Jumper Settings table shows the jumpers to use for a specific COM port and IRQ.

 Also see the information below for some hints regarding the resetting of jumpers.

Hint 1: If you are replacing an old modem, try using the same COM/IRQ setting that was used for that modem.

Hint 2: To determine your system’s current COM port and IRQ assignments, you may do the following (see your computer manual for additional methods):

• Windows 95: Click on the Control Panel and System icons. Click on the Device Manager tab. Highlight Computer and select the Properties button and the View Resources tab.

• Windows 3.x: At DOS prompt type MSD [Enter] to access MS-Diagnostics, e.g., C:\DOS or C:\WINDOWS, etc. Follow the instructions that display on-screen.

Hint 3: Most operating systems will accommodate installation of a modem on COM port 4 and IRQ3 (or COM port 2 and IRQ3). You may want to try these settings first.

The I/O Address for COM 4 = 02E8 (or /dev/cua3 for UNIX or LINUX)
The I/O Address for COM 2 = 02F8 (or /dev/cua1 for UNIX or LINUX)


Note: COM 2 is usually assigned to an external connector at the back of the computer. If you plan to use COM 2 for the internal modem, you should disable COM port 2 in your computer’s BIOS (see your system manual).

Important: If the COM4/IRQ3 (or COM2/IRQ3) jumper settings result in a conflict then use another COM port setting (COM 3 or 1) or another IRQ (5, 7, 10, 11, or 12).

The I/O Address for COM 3 is 03E8 (or /dev/cua2 for UNIX or LINUX) The I/O Address for COM 1 is 03F8 (or /dev/cua0 for UNIX or LINUX)

Note: COM 1 is usually assigned to the external connector at the back of the computer. If a mouse is not used for COM port 1 and you need to use COM 1 for your internal modem, you should first disable COM 1 in your computer’s BIOS (see your system manual for information).

For a non-plug and play system, remove the jumpers from the card and reset them to correspond to the specific COM port and IRQ you will be using.

Hardware Installation

Be sure that the modem card jumpers are properly set as described above.

1. Turn off the computer and disconnect its power cord.

Note: If you are replacing an existing internal modem please remove it and its software before you start.

2. Unfasten the computer cover’s mounting screws.

3. Remove the computer cover being careful not to damage the internal cabling.

Note: Before handling internal components , you may want to ground yourself with an anti-static wrist-strap. (You do this as a precautionary measure to protect electronic component from a possible discharge of static electricity from your body.)

Troubleshooting

Windows 95 does not detect the modem.	Modem card is not properly installed in 16-bit ISA expansion slot, or bad expansion slot.
Windows 95 Plug N Play modem installed, but applications software will not function.	Go to Control Panel, double click System, click Device Manager, click Modem. Select the installed modem, click Remove, click OK, click Refresh, click OK. Verify correct installation by double clicking Modems, click Diagnostics, select the com port the modem is on, click More Info, and verify response.
Modem hags up when incoming call is received.	Disable call waiting function for the on-line service, Internet connection, and/or communication software you are using.
Modem does not seem to perform at 33,600 bps.	The service or modem you normally communicate with can only operate at a slower speed.
No dial tone.	Check phone line connection. If modem is plugged into a phone line splitter, remove it and try connecting the line directly to a telephone wall jack.
Cannot contact Internet provider with recommended AT command string.	Check with your Internet provider for requirements.
Characters appear twice on screen.	Communication software not set up for full duplex operation.
Incomprehensible characters appear on screen.	Data bit, parity, and stop bit settings are incorrect.
Windows 3.x Systems - Modem Not Found	Use the communications software’s auto-search function to determine if your system can communicate with the modem. If the system cannot communicate with it, the modem will have to be reconfigured. Before reconfiguring it, make sure that the Windows 3.x modem IRQ setting matches the IRQ you have selected for it. If you have a Windows 3.x system, you can check these settings as follows: • Select Control Panel, double click on Ports, and select the COM port used by your modem. • Click on Settings and on Advanced, and make sure the IRQ selection matches the modem’s IRQ. • Restart Windows and repeat the communications software auto-search function.
DOS/Windows 3.x - IRQ Conflicts - Legacy Mode	IRQ conflicts occurring in a DOS/Windows 3.x system cannot be easily determined. If you are having a conflict with the modem card and you are not sure which IRQs are being used by the other devices (e.g., Sound Card, Network Card, Video Capture board, etc.), check the documentation for each of those devices to make sure that the correct IRQ’s are being used by them.
DOS/Windows 3.x - COM Port Conflicts	Run MSD (Microsoft Diagnostics) from the DOS prompt and check the COM Ports section to determine which addresses are free. Addresses for the COM ports are set up as follows: 03F8h=COM 1, 02F8h=COM 2, 03E8h=COM 3, and 02E8h=COM 4. Sometimes MSD will misrepresent a COM port number, so ignore the COM port number shown on-screen and use the aforementioned address list instead (e.g., if 03F8h, 02F8h, and 03E8h are displayed then 02E8h=COM port 4 is free).
Windows 95 - IRQ Conflicts - Legacy Mode	Internal modems cards are usually designed to work with an IRQ 3 or IRQ 4 interrupt. Because this modem works with a number of other IRQs as well, interrupt conflicts should not occur too often. However, if you think you have an IRQ conflict then perform the following steps: • Turn off your computer and remove the modem. • Turn your system on and let Windows 95 load. • Double-click My Computer, Control Panel, and the System icon. • From the System Properties window, click on the Device Manager tab. • With Computer highlighted, click on the Properties button. • The Properties window will show you the IRQ’s that are currently in use. • You can assume that an IRQ is available for use if it is not listed. • Using an available IRQ, reconfigure your modem and reinstall it as instructed in the manual.
Windows 95 - Resolving IRQ Conflicts (Plug and Play)	Windows 95 may have problems with the modem board even if the board was properly installed and the .INF file was properly loaded. Reason: unlike DOS and Windows 3.1, when Windows 95 is installed on a plug and play system it does not adequately support devices that share IRQs. To resolve a Windows 95 IRQ conflict, go to Computer Properties and manually select the modem’s IRQ. If this does not work, then free an IRQ line by deleting or removing existing devices or boards and manually select the modem’s IRQ from the Computer Properties screen.
Windows 95- Check if INF File Was Loaded	To determine whether the .INF file was loaded, go to the Windows 95 Control Panel and select the Modem icon. Check to see if your modem’s name displays in the Modems Properties screen. If not, then: 1) the wrong .INF file was loaded, 2) Windows 95 failed to recognize the modem, 3) the Cancel button was mistakenly pressed during installation, or 4) the modem type name was previously removed. To resolve this problem, try reinstalling the board. If reinstalling the board does not resolve the problem, try installing a different modem to see if it works. If the other modem works, then there is a hardware or COM Port conflict with the new modem.

 

 

Communications Software

After setting up your modem, as describe above, we recommend that you install the supplied communications software according to the instructions that are furnished with it.

The communications software package is very user friendly and it works well with this particular modem. The software will, moreover, simplify your dialing, data communications, and faxing operations.

If you have an IBM or compatible PC, you can also use Microsoft’s Terminal icon (or Hyperterminal icon for Windows 95) for general communication purposes. You may also use your own communications software if you prefer.
