Description

Not connnected

5V0

PWR Input 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.

LED1

LD1

Output

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.

pin which allows for the possibility of bring- ing out an additional

LED traffic indicator out of the VDIP2 board. For example, if the
