Communication baud rate: 9600.8.N.1        Data format: hexadecimal

Parts Communication protocol and function:

Read the temperature:

For example:

A module as a slave communicate with master by RS485,and,read the temperature and humidity of 16 ports .

The master send the message as this format:

Send content                                              Bytes        Send data                 Meaning

Slave address                                              1               01                               No. 01 Slave

Register starting address                       2               0005                          The Command of reading

The number of words for reading        4               0020                          Read the 32 words of temperature and humidity

CRC check                                                   2               XXXX                          The CRC result

 

The slave feedback the temperature and humidity value one by one from port0 to port f.

The feedback format from the slave:

CRC check                                                 2               XXXX                  The CRC result

 

The 00_AC_01_77 means: 

0:          +

0AC:       172    (10 times of temperature)

01_77:   375    (10 times of humidity)

 

The FF_83_01_9C means: 

F:           -

F83:       125    (10 times of temperature)

01_9C:   412    (10 times of humidity)

 

The temperature value display on the LED screen through J2
