1. Introduction
1.1 General

USB ports (from one or two different PCs). On the remote side, each extended USB port
terminates into a 4-port USB hub. This allows up to 4 USB devices to be connected to
each extended USB port for a total of 8 ports.
Depending on the UTP cable the unit can extend the USB port to 230 meters (750 ft).
Maximum distance using Cat5 (UTP or STP) cable is 150 meters (500 ft), and using Cat6
(UTP or STP) cable is 230 meters (750 ft).
