Extend USB 2.0 over CAT5 up to 330 feet (100 meters)

The GefenToolBox USB 2.0 4-Port Extender extends a USB source up to 330 feet (100 meters) using a single CAT5 cable. This product supports USB 2.0 with data rates up to 480 Mbps in addition to backward-compatibility with USB 1.1. The Receiver Unit allows the connections of up to four (4) USB devices, providing access to printers, scanners, cameras, external storage media, digital signage, and automated control systems.
How It Works
Use the supplied USB cable to connect the USB 2.0 4-Port Sender Unit to the USB host (source) device. Connect the USB devices to the Receiver Unit. Use a CAT-5 cable to connect the Sender Unit to the Receiver Unit. Connect the included locking 5VDC 4A power supply to the Receiver Unit, then connect the power cable to an available electrical outlet. The LED indicators on the Sender Unit and the Receiver Unit provide status on power and data transmission activity.
The Sender Unit is normally powered by the USB Source device. If The Source device cannot provide sufficient power, an additional 5V 4A Power Supply with Locking Connector (EXT-PS54-AULPN) may be ordered (See Optional Accessories listing below).
