USB Monitor LED (LED4)
The USB monitor LED (
LED4
) indicates that USB communication has
been initialized successfully and you may connect to the processor using a
Vi+ EZ-KIT Lite session. This should take approximately 15
seconds. If the LED does not light, try cycling power on the board and/or
reinstalling the USB driver.

When Vi+ is actively communicating with the EZ-KIT
Lite target board, the LED can flicker, indicating communications
handshake.
