Description
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 VDIP1 board. For example, if the VDIP1
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 required

Can be used by an external device to reset the VNC1L. This pin can be used
in combination with PROG# and the UART / parallel FIFO / SPI interface to
program firmware into the Vinculum
This pin is used in combination with the RESET# pin and the UART / parallel
FIFO / SPI interface to pro gra m fir mware into t he VNC1L.
