This USB extender uses inexpensive CAT5/5e/6 network cable to extend the range of a USB peripheral. Attach a length of network cable (up to 198 feet long) to the remote and local units, and then connect your USB device. You'll have a reliable, wired connection to your USB peripherals from your PC with no signal loss. Now your Web camera, scanner or printer doesn't need to be next to or even near your computer. Requires Microsoft Windows 98SE+ or Mac OS 8.6+. Network cable sold separately. Please note, only compatible with USB 1.0/1.1 devices.
