These instructions are for users of either Windows® 3.1, Windows 3.11, or Windows for Workgroups. You'll need these items from your U.S. Robotics modem box: the modem a phone cord Connections CD Winmodem disk Guide Installation Plus: a screwdriver (not included) 3 WINMODEM INSTALLATION UNDER WINDOWS 3.X This chapter will walk you through the installation of your Winmodem. There are two parts to the installation: hardware (the modem) and software. The modem must be installed before the software. How to Insert the Modem NOTE: Before installing your modem, write down its serial number. (You'll 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. 1. Shut down Windows, turn off your computer and unplug it from the electrical outlet. 2. Unplug any peripheral devices (printer, monitor, keyboard) from the computer. NOTE: Your Winmodem supports Plug and Play installation, the fastest, easiest way to add new features (a modem, a sound card, etc.) to your PC. 4 WINMODEM INSTALLATION UNDER WINDOWS 3.X 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. 4. CAUTION : To avoid the risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged. 3. Find an empty ISA expansion slot at least as long as the gold edge of your modem. (ISA slots have 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. Remove the screws from your computer's cover and then remove the cover. Your computer may look different from the drawing on the right, but the basic principle for removing the cover should be the same. Refer to your computer manufacturer's manual if you need further instructions. 5 WINMODEM INSTALLATION UNDER WINDOWS 3.X 5. Holding the modem by each corner, align the gold edge with an empty expansion slot. Push down gently until the modem snaps into the slot. (Note: The drawing shows horizontally aligned expansion slots. Some computers have vertically aligned slots. The instructions apply to both styles.) 6. You'll have to apply a little pressure to seat the modem properly. Sometimes a gentle back-and-forth motion helps get 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. Take the modem all the way out and try again. Once the modem is seated, secure it using the screw you removed in step 3. Put the computer's cover back on and replace the screws. If you currently have a phone plugged into the wall jack you're going to use for the modem, disconnect the phone's cable from the jack. (See Warning statement on next page.) 7. 8. 6 WINMODEM INSTALLATION UNDER WINDOWS 3.X 9. Plug one end of the phone cable that came with the modem into the TELCO jack at the rear of the modem. 12. Plug the power cords, cables, and peripherals back into the computer and turn the computer on. If Windows does not start automatically, please start it now. 13. WARNING : The phone jack you use must be 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. 10. Modem Initialization Your Winmodem came with a diskette that contains an installation program that will help your computer finish installing the modem. The installation program will also copy modem programs from the disk onto your computer's hard drive. Plug the other end of the cable into the wall jack. If you want to use a telephone on the same line as the modem, plug the telephone's cable into the modem's PHONE jack. 11. 7 WINMODEM INSTALLATION UNDER WINDOWS 3.X 3. Running the Installation Program on a Windows 3.1 or 3.11 For Workgroups System After inserting the Winmodem follow these steps: 1. 2. Insert the installation diskette. Click on Program Manager. Now click File and select Run. In the Command Line text box, type a:\install.exe. Click OK. The next screen will tell you where the Winmodem installation files will be located. Click Continue to copy the Winmodem files to this directory. If you wish to copy the Winmodem files to a different directory, type the path to that directory in the Install to text box. 8 WINMODEM INSTALLATION UNDER WINDOWS 3.X 4. This screen tells you that the software will create the new Winmodem directory. Click Yes. 6. This screen tells you that modifications have been made to your Windows system files. Click OK. 5. This screen lets you know the installation software is being loaded to your hard drive. Let it finish. 7. This screen tells you that the software will automatically detect available communications ports for the Winmodem. Click OK. 9 WINMODEM INSTALLATION UNDER WINDOWS 3.X 8. After the software detects the available COM ports, it will ask you select one for the Winmodem. Highlight the first or lowest one and then click OK. Be sure to write the number of the free COM port you select. See the troubleshooting section of this manual if the software does not locate an available COM port. 9. Your Winmodem software has been installed. Click Restart Windows to finish the process. 10 WINMODEM INSTALLATION UNDER WINDOWS 3.X 10. Windows will now restart. At this point, you will see a new Winmodem group. · (Note: If you do not see a new Winmodem group, you will instead see the Configuration screen. You will have to choose an available I/O address and an available IRQ. Do not select "Let plug and play configure... ") For the I/O address: Choose any on the list. · For the IRQ: The COM port/IRQ combinations shown here work with most computer set-ups: COM IRQ 1 .....................4 2 .....................3 3 .....................5, 7, or 9 4 .....................5, 7, or 9 11 WINMODEM INSTALLATION UNDER WINDOWS 3.X · · If you have a sound card, SCSI card, or game card, it might be using IRQ 5 or 7. Do not make 5 or 7 your first choice, because it might not be available. Once you've chosen a combination, restart Windows. Click on Program Manager. You should see the Winmodem group. If you do not see this group, try a different combination of resources. If you chose an unavailable I/O address, you will get an error message. Choose another I/O address in the Configuration dialog box that appears. · If you chose an unavailable IRQ, you may encounter problems when your communications software program tells you it cannot find the modem. At that point choose another IRQ in the Configuration dialog box. (You can find it by clicking the Configurator icon in the Winmodem group in the Program Manager window.) · Once you've finished installing your modem, you are ready to install the Connections CDROM (included with your Winmodem.) Please turn to the section entitled "Software Installation"(page 29). 12 BEFORE YOU BEGIN (WINDOWS 95 USERS) Your U.S. Robotics modem is a Plug and Play device. 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 ...
