Do This First Please read the following tips carefully before attempting to install your new modem. For WINDOWS 95 INSTALLATION If you are replacing the modem in your computer system with this modem, be sure to remove all other modem drivers. Go to: Start-Settings-Control Panel and double-click on the System icon. Select the Device Manager tab. Doubleclick on the Modems icon in the device tree to show the modems installed.
To find the Windows 95 Version on your system, select: Start-Settings-Control Panel. Double-click on the System icon. If the version of Windows 95 is 4.00.950 or 4.00.950A, go to: Start-Programs and select Windows Explorer. Go to the UNIMODEM directory of the CD-ROM (the UNIMODEM driver is sometimes supplied on a separate floppy) that came with your modem and right-click on UNIMODV.INF (or UNIMODV, whichever is displayed) then click on Install. Restart your computer to enable the drivers.
Do not reassign an interrupt that is already in use by an ISA card to the PCI bus. Since each BIOS manufacturer has a different way of handling these configurations, you may have to use trial-and-error to get your modem properly configured. Be sure to Save the settings before exiting the BIOS Setup. You are now ready to install the modem. Proceed to the Installing the Modem section. For WINDOWS NT 4.
Installing The Modem HARDWARE INSTALLATION 1. Switch off the computer and all peripheral devices connected to it. 2. Unplug the computer power cord from the wall receptacle. 3. Remove the computers cover. Refer to your computer owners manual for instructions. 4. Remove the screw securing the expansion slot cover behind one of the computers available PCI expansion slots. Lift the expansion slot cover out as shown below.
5. Firmly, but gently, insert the modem into the available PCI expansion slot. Ensure that the card is seated properly before securing it with the screw removed in Step 4, as shown in the following diagram: Fig. 6: Installing The Modem 6. Put the chassis cover back on the computer. 7. Be sure that all power switches are in the OFF position, then reconnect the power cables to the computer and its peripherals. 8. Connect the telephone line cable to the Line (Telco) jack as shown in Fig.7. 9.
CONNECTING DEVICES TO THE MODEM Fig.7: Connecting Devices On the rear panel of your modem are input jacks to connect devices to the modem. As shown in the diagram, there are jacks for connection to a phone and to a phone line. The connector labeled Line (Telco) is meant to be connected to a standard analog phone line. To help reduce the load on your phone line, it is recommended that the modem be the only device connected.
CONFIGURING WINDOWS 95 Step 1 Upon startup, Windows 95 detects the modem and displays the New Hardware Found dialog box. Select Driver from disk provided by hardware manufacturer then Click OK. Step 2 If Windows asks for an installation disk, click OK and type A:\ in the dialog box that appears and click OK. Step 3 After the installer has copied the .INF files to the hard disk, a New Hardware Found dialog box should appear prompting for the Wave Device for Voice Modem. Click OK.
Step 4 Click OK to copy the Wave Device .INF file from the A:\ drive (or CDROM Drive) to the hard drive. Step 5 To determine what COM port and IRQ is assigned to the modem in Windows 95, click on the Modems icon in Control Panel and select the Diagnostic tab. Click on the COM Port icon next to the modem and then click on the More Info button to view the modem properties.
CONFIGURING WINDOWS 95 OEM SR2 Step 1 Upon startup, Windows 95 detects the modem and launches the Update Device Driver Wizard dialog box. Insert the diskette containing the modems Windows 95 .INF files and click Next >. Step 2 After Windows 95 has found the updated drivers for your modem, click Finish. Step 3 If Windows asks for an installation disk, click OK and type A:\ in the dialog box that appears and click OK.
Step 4 After the Wizard has copied the .INF files to the hard disk, it should detect Wave Device for Voice Modem and prompt for its driver. Click Next>. Step 5 Click Finish to copy the Wave Device .INF file from the A:\ drive (or CD-ROM Drive) to the hard drive. Step 6 To determine what COM port and IRQ is assigned to the modem in Windows 95, click on the Modems icon in Control Panel and select the Diagnostics tab.
Step 7 Remember this COM port number. When you install your Data/Fax software or internet browser program, you may need to set your modem port location to this same number.
CONFIGURING WINDOWS NT 4.00 In order to install the modem in Windows NT, you must prepare the installation utility supplied on a separate floppy diskette. This diskette should be labeled Windows NT Installation Utility. This program will allow for easy installation and uninstallation of your PCI Windows Modem. Step 1 Install your modem into an available PCI slot (see the Do This First section for important preinstallation information).
Step 7 After the installation utility has finished installing the drivers, restart your computer to enable the drivers. Step 8 Click on the Modems icon in the Control Panel. Verify that Windows NT has correctly found the modem. Step 9 If you wish to use your modem to dial into a Windows NT Remote Access Server or wish to connect to the Internet, you will need to configure Dial-up Networking. Go to: Start-Settings-Control Panel and doubleclick the Network icon.
NT may ask for its own disks or CD-ROM for some files. Insert as required. After you have installed Remote Access Service add the appropriate protocols as directed (i.e.. TCP/IP for Internet Access). Step 10 At the Remote Access Setup dialog box, click on Add RAS Device you wish to add and Click OK. . Select the Step 11 Click Continue to finish the Installation. Step 12 After Windows NT has completed the binding process, allow Windows NT to shut down and restart the computer.
Installing and Configuring Communications Software If your modem came with a communications software package, it is strongly recommended that you use this software for your modem. Its default installation parameters have been specially configured to work with this modem. The Users Guide for this program can be found inside the modem package. It can be supplied in either soft-bound copy or on CD-ROM (depending on the model you purchased). Some configurations are packaged without communications software.
Using the Modems Voice Features This modem supports TIA IS-101 commands applicable to a Telephone Answering Device. In order to take advantage of this feature, you will need a Sound Blaster® compatible sound card equipped with an external microphone and external speakers. A software application; such as the one supplied with the modem; which supports these TAD functions is also required.
Troubleshooting This section lists some common problems and offers suggestions for a solution. It is important to remember that this modem is a Windows 95/NT based modem and requires 32bit virtual device drivers. It therefore cannot work in Windows 3.1 which cannot use these drivers. The modem also cannot work in DOS regardless of version. It is a software installed device and has no provisions for manual configuration.
STEP 2: Check Modem Properties. From the Device Manager tab within System Properties, double-click the Modems icon in the device tree to show what modems are installed. Highlight your modem by clicking once on the icon and then click the Properties button. Read the Device Status under the General tab to see if the device is working properly.
If you receive an error message or the panel is blank, go to the Does Not Install section. STEP 4: Does Not Install. The most likely reason for a non-installation in Windows 95 is a lack of IRQ resources. The modem needs one IRQ and two I/O addressees in order to function. Modern computer systems are usually equipped with soundcard, CD-ROM drive, Hard-drive, floppy drive, video card, two COM Ports, one LPT port, keyboard, and a mouse.
Certain full-featured sound cards require three IRQs to support all their functions. When one becomes available, they take it. This situation requires that you remove your sound card, free an interrupt, install the modem and verify its operation, and then reinstall the sound card. This procedure may also work for sound cards that have lost their sound after the modem has been installed or if the modem will not install in a system with a sound card.
If you cannot find a particular file, it usually means it was not installed. After all instances of these files have been deleted, restart your system. Windows 95 and 95a users see below. If you are using Windows 95 OEM SR2 (see the Do This First section for Windows 95 for instructions on how to determine your Windows 95 version), you need only delete the files listed.
When a file is found, it will have the name oem#.inf. Delete only an oem inf file. To delete a file, highlight the file name by clicking once and then select File-Delete from the File menu. After the file is deleted, you now need to find the other inf file. Go to the Advanced tab and type the following in the Containing text field: V.90_PCI_Windows_Modem as shown below. After Windows finds the other file, delete it as before.
Common Problems: No Dialtone Error Make sure you have connected the phone cable into the right connector on the back of the modem. See Figure 7: Connecting Devices. You may have too many devices connected to the phone line. Remove all other equipment. Your modem may not recognize overseas dialtone. Use ATX0 to have the modem ignore (not look for) the dialtone before dialing.
You may have other telephone devices connected to the phone line. To help your modem achieve the best connection possible, remove all extra devices connected to the telephone line when the modem is in use. This includes extension phones, answering machines, cordless phone bases, caller ID boxes, etc. Dont just disconnect the phone cable from the units. Disconnect the phone cable from the wall. This reduces the load on your phone line and keeps signal attenuation to a minimum.
hear a hissing or humming sound in the background? Is there popping or crackling during your call? These are phone line problems. In the case of distortion, your phone line is bad. Humming may be due to the cabling inside your residence coming too close to a high current appliance or you may have a cordless phone recharger base connected to the phone line. Popping or crackling usually indicates a loose connection to the outside line or water dripping on the hookup outside your house.
