About the LED indicator
a. When module is power on, POWER LED is always ON (red).
b. When module enter to set mode (DIP 8 ON), SET LED is always ON
(red).
c. When module is transmitting,
if you use RS232 port, RS232 LED blinks (green) regularly.
if you use RS485 port, RS485 LED blinks (green) regularly.
if you use USB port, USB LED blinks (green) regularly.
d. When module is receiving, RF LED blinks (blue) regularly.
