NOTE1：The factory default baud rate is 9600bps,n.8.1;The communication address of Modbus
protocol is 01 (1 ~ 247), E1 means even check 1 stop bit, O1 means odd check 1 stop bit Two stop bits,
N2 means two stop bits without check;
NOTE2：The above interface is used to show the meaning of the display content. Due to the
different functions of the instrument, the display symbols will increase or decrease.
NOTE3：When RS485 communicating, the telephone sign will flashes.
