<Notes>
nReload Pin function:
1.
After device is powered up, If put this pin to low more than 3 seconds and then put to High,
It will restore the product parameters to factory setting.
We strongly suggest user to fan out this pin.
ACTIVE Pin
1.
When there are data transmiting and receiving, This LED will flashing. If there is no data
transmit and receive, It will output High.
LINK Pin
1.
When Ethernet connected normal, It will output Low, If there is no Ethernet connection, It
will output High.
