Over Voltage alarm

Voltage threshold can be set, divide into high voltage and low voltage threshold, when the measured voltage exceeds the threshold, it can alarm

The default high voltage threshold is 300V, the default low voltage threshold is 7V.

Communication interface

RS485 interface.

Communication protocol
Physical layer protocol
Physical layer use UART to RS485 communication interface.

Baud rate is 9600, 8 data bits, 2 stop bit, no parity.

Other instructions
1 RS485 interface is passive output, need external connect 5V power supply and the the external power supply should ＞100mA.

2 When the input test voltage is less than 7V, it must supply 5V independent work voltage through MICRO USB port；
