6.1 LED indication

On the AS311, five status LEDs are provided as follows. These LEDs are useful to check the AS311 operation status and the communication status.

RUN	RUN	Indicates the AS311 operation status.
TX1		Lit when the AS311 is in ready state.
RX1		Not lit when the AS311 is in error or under initialization.
TX2	TX1	Indicates the channel 1 communication status.
RX2		Lit while some data is transmitting from the AS311.
	RX1	Indicates the channel 1 communication status.
		Lit while some data is receiving into the AS311.
	TX2	Indicates the channel 2 communication status.
		Lit while some data is transmitting from the AS311.
	RX2	Indicates the channel 2 communication status.
		Lit while some data is receiving into the AS311.
