Description
Debug connector, 6-way 2mm pitch female connector.
USB Mini-B type connector for connecting to PC.
FTDI FT232R USB to serial converter device.
2 port buffer device used to convert VNC2 debug signal
from single bit bidirectional signal into separate
transmit and receive signals for FT232R. Data flow
direction control on the buffer is carried out by the
TXEN output from the FT232R. TXEN at logic ‘1’ will
indicate transmit.
LED indicating transmit or receive traffic.
LED indicating power status.
FET switch used to switch power on or off on connector
CN2. FET switch is controlled by PWREN# output from
FT232R.
Debugger Interface.
Not connected.
Module ground supply pin.
Connects to VNC2 RESET# pin. This pin may be
used in combination with PROG# and the UART
interface to program firmware into the VNC2
device.
Connects to VNC2 PROG# pin. This pin is used in
combination with the RESET# pin and the UART
interface to program firmware into the VNC2
device.
5V output to V2DIP module (from USB bus power).
