USB Connectors
There are two USB ports at the rear panel, and one UBS port at the front
panel. Each permits connection of USB peripheral devices directly to the
system without having to use an external hub.
USB2 and USB2 are standard USB connectors accessible from the rear
panel. USB2 Header is a 4-pin single-line header that connects to a
standard USB connector (USB1) accessible at the bottom of the front
panel. An internal cable connects USB2 Header to an interface board
behind the front panel.
If more USB devices are needed, connect an external hub to any USB
connector.
