5.0 V module supply pin. This pin provides the 5.0V output on
the USB ‘A’ type socket, and also the 3.3V supply to VNCL2,
via an on-board 3.3 V L.D.O.

USB port 1 traffic activity indicator LED. This pin is hard wired to
a green LED on board the PCB. It is also brought out onto this
pin which allows for the possibility of bring- ing out an additional
LED traffic indicator out of the VDIP2 board. For example, if the
VDIP2 USB connector is brought out onto an instrument front
panel, an activity LED could be mounted along side it.
