D-Link DSL-200 Installation Guide
http://support.dlink.com

System Requirements:
The Modem can be installed on any IBM compatible Pentium PC with a minimum of 32MB of RAM running Microsoft Windows 98/98SE, Windows 2000 or Windows Me operating systems.

Additional Requirements:

VPI/VCI Values - Your ADSL service provider will provide information that you will need to configure the Modem. The VPI (Virtual Path Identifier) and VCI (Virtual Circuit Identifier) numbers are used to define a dedicated pathway (called a Permanent Virtual Circuit or PVC) used for your ADSL service. Be sure to have this information handy before you begin the installation.

Micro-filters - Since ADSL and telephone services share the same copper wire to carry their respective signals, you may need to install a micro-filter (low pass filter) device for each telephone that shares the line with the ADSL line. Micro-filters are easy to install in-line devices, which attach to the telephone cable between the telephone and wall jack.

USB Port - In addition to the Windows OS, you will need a USB (Universal Serial Bus) port on your computer. These are commonly installed on newer computers (usually directly on the motherboard), however older PCs may require an additional installation.

User Name and Password - Your ADSL service provider or ISP will assign a User Name and Password for your account. You need to enter these during the dial-up procedure to connect to their network and the Internet. You can write these in the space provided if you wish. Keep this information in a safe place and do not reveal it to anyone.

Install Modem:
Before starting the software setup process, exit all Windows applications currently opened on your PC. The software installation procedure is identical for the Windows 98/98SE, Windows Me, and Windows 2000, and is therefore described in the same section.
DO NOT CONNECT THE USB CABLE. You must install the software driver before you connect the device to your computer via the USB cable. You will be prompted to connect the device during the installation. Connecting the USB cable at this point will initiate the Found New Hardware process.

Install Modem Driver:
1. Insert the DSL-200 Installation CD into the CD-ROM drive. Double-click on My Computer icon located on your desktop. Double-click on the CD-ROM icon.
2. Double-click Setup.exe to start the installation procedure. A notification message will appear indicating that the setup process has begun.
3. The Welcome window recommends that you exit all other programs before you run the Setup program. Make sure you have quit all other programs and click Next.
4. In the Select ISP window, select ‘Other Service Provider’ then click Next.
5. In the Select Driver Type window, choose ‘WAN Driver’ and click Next.
6. In the Communication Settings window you must provide the PVC settings, encapsulation method and modulation method for configuring the Modem. Type in the VPI and VCI values in their respective fields. 
7. In the same window, select the proper Encapsulation method using the drop-down menu. Please contact your service provider for the appropriate Encapsulation settings. There are two possible settings, RFC 2364 PPPoATM LLC Encapsulation or RFC 2364 PPPoATM NULL Encapsulation. If your ADSL service provider does not specify one, use the default setting (RFC 2364 PPPoATM NULL Encapsulation).
8. Again in the same window, select the proper Modulation settings using the drop-down menu. Please contact your service provider for the appropriate Modulation settings.  There are four possible settings from which to choose, T1.413, Multimode (suitable for Alcatel’s and ADI’s non-standard T1.413), G.Lite and G.DMT. Click Next to continue.
9. The Start Copying Files window appears. Click Next to copy the needed driver files.
10. In the Setup Complete window, click Finish.
11. The DSL Installer window asks you to plug in the Modem. Plug the rectangular end of the USB cable into the USB port of your PC, and then plug the square end of the USB cable into the USB port of the ADSL Modem. The USB Modem will be detected and messages will be displayed as the modem software is installed.
For Windows 2000 applications, the 'Found New Hardware Wizard' window indicates the modem has been installed and suggests you reboot the system to have new settings take effect. Click Finish.
12. You now need to restart the computer to complete the installation of the driver. You may do this now by clicking Yes. A new icon (two arrows) appears in the System Tray on your desktop.
