Data and power over category cable. 

Now, you can locate Logitech Tap nearly anywhere in your meeting rooms. With the Cat5e Kit, connect Tap up to 40 meters away from the meeting room computer with data and power carried over category cable. When connected to the meeting room computer with a USB cable, Tap needs its own power supply. But since the Cat5e Kit delivers both power and data over category cable, there's no need to find an outlet at the table. Use the 10 meters of cable included with the Cat5e Kit or supply your own cabling for runs of up to 40 meters. Cat5e allows for precise cable lengths, reducing clutter beneath tables.
