Windows® 95 can automatically identify a Plug and Play device and determine if your system has the resources necessary to support the device. However, Plug and Play will not work if you do not have resources available or if devices on your system are not reporting resource usage correctly. Here's how you can verify that your system has the necessary resources before installing the modem: 1. Click the Windows 95 Start button, point to Settings, and then click Control Panel. 2. Double-click the System icon. 3. When the "System Properties" screen appears, click the Device Manager tab. 4. Double-click Computer and the "Computer Properties" screen appears. 5. Select the option at the top of the screen to show Interrupt Requests (IRQs). You will see the IRQs your system is currently using. If IRQs 3, 4, 5, and 7 are being used, you need to free an IRQ before you begin installation. This process involves moving a device from the IRQ you want to use to a different (and usually higher) IRQ setting. Please read the documentation for (or contact the manufacturer of) the device that is currently using the IRQ you want to use for your modem to learn more about how to free the IRQ for your modem. 3 BEFORE YOU BEGIN (WINDOWS 95 USERS) Determining Your Version of Windows 95 Follow these steps to determine your version of Windows 95. This information will be important during installation. 1. Click the My Computer icon on your desktop with the right mouse button. 2. Click Properties. 3. In the "System Properties" screen, look at the system information under the General tab (circled in the following screen image). The number following the text "Microsoft Windows 95" will end with "950", "950a", or "950b". This indicates your version of Windows 95. Write this number on the blank below for later reference. Then click OK. 4 Windows 95 version _________________ INTERNAL MODEM INSTALLATION WITH WINDOWS® 3.X You will need these items from your U.S. Robotics® modem box: A Word about COM Ports and IRQs Most computer accessories -- mouse, sound card, enhanced graphics card, scanner, etc. -- require a special connection through which they can communicate with the computer. For some devices, this connection is called a communications (or COM) port. Most computers have 1 or 2 COM ports, though they can have up to 4. Although internal modems do not connect to COM ports directly, they do require a COM port setting, which is determined by the setting on the modem's COM jumper pins. modem phone cord ConnectionsTM CD microphone Plus: screwdriver (not included) 5 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X Each COM port uses an interrupt request (IRQ). An accessory uses an IRQ to get the attention of your computer's centralprocessing unit (CPU) so that the accessory can perform a task. The computer stops what it's doing, depending on the priority of the request, to help the accessory perform its task. When two accessories share an IRQ, it's like two people asking different questions in unison to a third person. Just as the person being asked the two questions cannot understand either request, a computer can lock up or otherwise fail to communicate properly with your modem when there is an IRQ conflict. KEY POINT: Accessories cannot share COM ports and should not share IRQs. When accessories try to share settings, they will either not work properly or not work at all. 3Com has set your modem to a default Plug and Play setting which is ideal for Windows 95 users. In this configuration, the shunts used to set your modem's COM port and IRQ settings are hanging from single jumper pins and will not affect your modem's settings. As a Windows 3.x user, you need to run the ComTest program (on the ConnectionsTM CD) to determine what settings your modem should use. 6 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X 3. The screen in the next column appears when NOTE: Some communications software programs require a particular setting for your modem (the RapidCommTM software, which shipped with your modem, does not). If you wish to use a program other than RapidComm, now is a good time to read that software's manual to determine what setting is required. ComTest starts. · If there is a modem in your computer which you are replacing with your new U.S. Robotics modem, go to "Testing an Installed Modem" on page 9 to determine which COM and IRQ settings the older modem is using. · If a modem is not currently installed in your computer, click Recommend settings for a new modem. Then click Next. How to Use ComTest to Determine Your Modem's Settings 1. Insert the Connections CD into your CDROM drive. 2. In Windows' Program Manager, click File and then click Run. Type d:\comtest.exe and press ENTER. This starts ComTest, the program that determines which COM ports and IRQs are available for use by your modem. 7 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X 4. Click Internal Modem. Then click Next. Write down the displayed settings here: COM Port_________ IRQ_________ You will need to know these settings later. Click Next. If you do not have a free setting, you will see a screen like the follwoing. Click Finish to exit ComTest. Go to "What to Do with ComTest's Recommendation" on page 10. 5. If you have a free setting, you will see a screen like this. (COM2/IRQ3 is free in this example.) 8 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X 6. When you see this screen, click Finish to exit ComTest. Testing an Installed Modem If there is a modem already installed in your computer, you can determine its COM and IRQ settings by selecting the Test an installed modem option. Follow the instructions on screen until you see the screen that tells you "Testing is complete." This screen will also tell you which COM and IRQ settings your present modem is using. These are the settings you want to use for your new U.S. Robotics modem. Write down the displayed settings here: COM Port_________ IRQ_________ Turn off and unplug your computer and remove your present modem using its documentation as a guide. Go to "How to Change the Modem's Settings" on page 12. If ComTest recommended COM 1/IRQ 4 or COM 2/IRQ 3, turn to "How to Change the Modem's Settings" on page 12. Otherwise, go to "What to Do with ComTest's Recommendation" on page 10. 9 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X What to Do with ComTest's Recommendation NOTE: If your communications software requires a modem setting that ComTest does not recommend, there is a good chance that the setting is being used by another device in your system. To free that setting in your system, consult your computer's manual. Go to "How to Change the Modem's Settings" on page 12. If ComTest recommended COM3/IRQ4 or COM4/IRQ3 Do not use either of these settings. While the COM port part of the setting is acceptable (ComTest only recommends COM ports that are not being used), the IRQ part of the setting 10 is not acceptable. When ComTest recommends either COM3/IRQ4 or COM4/IRQ3, the IRQ in the setting is being used by another accessory. You could use the suggested IRQ for the modem, but you run the risk that the modem and/or the other accessory sharing the IRQ might not work properly. If you do not have a sound card, use COM3/IRQ5. Write "COM3" and "IRQ5" where it will be convenient during the software installation. You will have to change the settings on your modem. Go to "How to Change the Modem's Settings" on page 12. If you do have a sound card, use COM2/IRQ3. To use this setting, you have to first disable your computer's second serial port (COM2). This is a pronged socket on the back of your computer. · Go to your computer manufacturer's manual. INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X · Find out how to disable the COM port. · Find out which of the sockets on the back of your computer COM 2. · If you have something plugged into that port, find out if you can plug it in somewhere else. Any accessory plugged into that port will not work after the port has been disabled. · Then return to this point in this manual to continue. After disabling COM2, you can use the COM2/IRQ3 setting. Write "COM2" and "IRQ3" where it will be convenient during the software installation and go to "How to Change the Modem's Settings" on page 12. If ComTest reports that "You do not have any available COM ports and/or IRQs" We recommend you disable COM1 or COM2. When you disable one of these COM ports, you can use it and its default IRQ for your modem. Go to your computer manufacturer's manual. · Find out which socket is COM1 and which is COM2. · If nothing is plugged into either port, you may choose either of the ports to disable. Your computer manufacturer's manual will tell you how to disable the COM port. · If one port does not have anything plugged into it, note if the port is COM1 or COM2. This is the port you'll want to disable for your modem. · If both ports are being used, you may be able to attach one of the plugged-in 11 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X accessories elsewhere so that you can disable its COM port. The accessory will not work once its port is disabled. If you've disabled COM1, you can now use the COM1/IRQ4 setting. Write this setting down where it will be convenient during the software installation. If you've disabled COM2, you can now use the COM2/IRQ3 setting. Write the setting down where it will be convenient during the software installation. Go to "How to Change the Modem's Settings" (on this page). damage your modem. Then take the modem out of its plastic bag. 2. Find the COM and IRQ jumper shunts (small black plastic pieces) on your modem's jumper pins (see the following diagram). How to Change the Modem's Settings 1. Always touch an unpainted metal part of your computer (the back is usually unpainted) to discharge static electricity before handling the modem. Static can 12 3. To change the COM port and IRQ settings, you need to reposition the jumper shunts on the COM port and IRQ pins. To do this, lift the jumper shunts off the pins. INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X TIP: Grasp the jumper shunts with a tweezers or needle-nosed pliers. DO NOT grasp too firmly, as you may crush the jumper shunts. If a jumper shunt seems stuck, gently rock it back and forth as you lift. Do not touch any other part of the modem or your computer with the tweezers/pliers. A jumper shunt needs to be sitting on both jumper pins in order to effectively set the modem to the desired setting. 4. Move the jumper shunt to the new setting. · The COM port setting can involve one to three shunts. The four possible COM port settings are as follows: 0 1 SE L COM 1 COM 2 0 1 SE L 0 1 SE L COM 3 COM 4 0 1 SE L · Unlike most COM port settings, the IRQ setting involves only one jumper shunt. Simply move the jumper shunt to the pins labeled with the IRQ you need. 13 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X How to Insert the Modem into the Computer NOTE: Before installing your modem, write its serial number in the space provided here: 1. Turn off your computer and unplug it from the electrical outlet. 2. Unplug any peripheral devices (printer, monitor, keyboard, mouse, etc.) from the computer. SERIAL NUMBER:_____________ You will find the serial number underneath the bar code on the white sticker on the modem and on the outside of the box the modem came in. If you ever need to call our customer support department, a customer support representative will ask you for the serial number. This will help him or her identify your modem. 14 TIP: Before you unplug anything, label the cords or make a sketch of how things are connected. This can be helpful when you plug things back in later. CAUTION : To avoid the risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged. INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X 3. Remove the screws from your computer's cover and then remove the cover, as shown in the following diagrams. Your computer may differ in appearance from these diagrams, but the basic principle for removing the cover should be the same. Contact your computer manufacturer or review their manual if you need further instructions. 4. Find an empty ISA expansion slot at least as long as the gold edge of your modem. (ISA slots are usually black plastic grooves lined with silver metal.) Unscrew and remove the expansion slot cover (the long narrow piece of metal that keeps dust from entering through the opening perpendicular to the slot). Be careful not to drop the screw into the computer. You will need it later to screw the modem into place. 15 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X 5. Holding the modem at each corner, with the gold edge facing the slot, push the modem down as gently as possible until it snaps into the expansion slot. (The drawings show horizontally aligned expansion slots. Some computers have vertically aligned slots. The instructions apply to both styles.) You need to apply a little pressure to seat the modem properly. Sometimes a gentle back-and-forth motion helps to fit the modem all the way into the slot. If you feel resistance, the modem may not be properly lined up with the slot. Do not force it into the slot. Remove the modem and try again. 6. Once the modem is in the slot, fasten it firmly into place using the screw that you removed in step 4. 7. Replace the computer's cover and fasten it with the screws you removed in step 3. 8. If you currently have a phone plugged into the wall jack you plan to use for the modem, disconnect the phone's cord from the jack. 16 INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X WARNING : The phone jack you use must be for an ANALOG phone line (the type found in most homes). Many office buildings have digital phone lines. Be sure you know which type of line you have. The modem will be damaged if you use a digital phone line. 9. Plug one end of the phone cord that came with the modem into the TELCO jack at the rear of the modem. Plug the other end of the cord into the wall jack. 10.If you wish to use a phone through the line the modem uses (when the modem is not in use), plug your phone's cord into the modem's PHONE jack. NOTE: You cannot use the modem and a phone at the same time if they share the same telephone line. 11. Plug the microphone into the MIC jack on the modem. 12.
