LED light
DATA Serial data indication
Two-color light, green indicates data reception, blue indicates
data transmission
I/O I / O status indicator
Two-color light, any one input has a signal, green indicator is on,
any one output has a signal, blue indicator is on, when there is
both output and input, both lights on at the same time, the
indicator is cyan.
PWR Power indicator
Red LED ， Always on
Note ：
Grounding: It is recommended to connect the case to the earth
