Serial status

LEDs The development board has two sets of serial port LEDs — four for serial port D and

eight for serial port B. The LEDs are connected to the TTL side of the RS232 or

RS422/485 transceivers.

Green means corresponding signal high.

Red means corresponding signal low.

The intensity and color of the LED will change when the voltage is switching.
