J1-1
5V0
5V0
IO5
PWR Input 5.0V module supply pin. This pin can be used to provide the 5.0V
input to the V2DIP1-48 when the V2DIP1-48 is not powered from the
USB connector (VBUS) or the debugger interface. Also connected to
DIL connector pins J1-2, J1-3 and J1-9 and J3-6.

I/O
USB port 1 traffic activity indicator LED. This pin is hard wired to a
green LED on boardthe PCB. It is also brought out onto this pin which
allows for the possibility of bringing an additional LED traffic indicator
out of the V2DIP1 board. For example, if the V2DIP1 USB connector is
brought out onto an instrument front panel, an activity LED could be
mounted along side it.

U1P
USB port 2 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 bringing an additional LED traffic indicator
out of the V2DIP1 board. For example, if the V2DIP1 USB connector is
brought out onto an instrument front panel, an activity LED could be
mounted along side it.
USB host / slave port 1 - USB Data Signal Plus with integrated pull up /
pull down resistor. Module has on board 27 Ω USB series resistor. This
pin can be brought out along with pin 5 to provide a second USB port, if
required

USB host / slave port 1 - USB Data Signal Minus with integrated pull up
/ pull down resistor. Module has on board 27 Ω USB series resistor. This
pin can be brought out along with pin 4 to provide a second USB port, if
