Modbus Communication protocol

The default set is 19200,1 start bit，8 data bit，1 stop bit，none.All data is 32 bit.

Other communications

Active sending protocol

1: The data is transmitted in ASCII code. For example, if 1234 is displayed, hexadecimal 30 31 32 33 34 will be passed.

2: The XOR operation is performed on all data[not contain a start character] before the XOR check bit，and can get a byte of data，Then the byte is converted into two ASCII codes. For example, the computed check is 0x4a, and the corresponding hexadecimal ASCII is 34 41.

3: 4-channel data, symbols and data, a total of four frames, each frame contains seven bytes of data, which are symbol + data;
