INTRODUCTION

Thanks for purchasing the D-Link 7-Port USB Hub. This easy plug

and play external device will allow your computer to connect to USB

interfaced monitors, printers, digital speakers, modems, digital

cameras, joysticks and other USB devices.

Technology Overview

USB stands for Universal Serial Bus. It’s a standard that has been

adopted by leading manufacturers within the computer industry to

define a new type of peripheral connection scheme. It is designed to

replace older parallel and serial ports, cables, and connectors with

something faster and easier to use. USB is:

?? Easier --Windows 98, 2000, Me or MAC OS will automatically

recognize newly installed devices.

?? Quicker -- You won’t have to reboot when installing.

?? Faster -- Top USB data speed is around 100 times faster than a

serial connection.

?? Greater Expandability -- Using USB hubs you can connect up to

127 devices to your computer.

?? Hot Swappable -- They just plug and go!
