The Power Hub is a small unit that allows your PC to be up to 100 feet away from the Smart Spider. The Power Hub also supports power daisy chaining when connected to the Smart Spider. It is positioned next to the computer and connects through a standard USB cable and a proprietary 48V AC/DC power adaptor. The Power Hub is then connected to the master speakerphone (i.e. MT503) unit via any standard CAT5 cable. Both data and power are routed to the speakerphone through the CAT5 cable.
