The REX Unit
The REX provides a USB Type A port for connecting standard USB devices. The REX allows you to connect
one USB device directly. Additional devices may be connected by attaching USB hubs to the REX. The REX is
powered either directly by the included power supply, or via the CAT 5e/6/7 link extension cable from the
LEX. The USB port delivers up to 1 Amp of current to the attached USB device.
