commands are in hexadecimal data. When the device leaves the factory, the default device address is 1,
and the default baud rate is: for modules and non-recording instruments: 9600, 8, n, 1 (for the recorder
series products, the default is: 115200, 8, n, 1).
1. Read data (Function code 0x03)

Data description: The data in the command is in hexadecimal. Taking Data 1 as an example, 02 18
converted to decimal value is 536. Assuming the data magnification factor is 100, then the t rue value is
536/100 = 5.36, and the others can be deduced by analogy.

3. Read and modify the device address (1) Read or query the device address
If you don’t know the current device address and there is only one device on the bus, you can query
the device address through the command FA 03 00 66 00 01 71 9E .
Device address
Function code
Starting address Data length
Checksum
FA
03
00 66

FA, which is 250, is the universal address. When you don’t know the address, you can use 250 to
obtain the real device address. 00 66 is the register of the device address.
For a correct query command, the device will respond. For example, the response data is: 01 03 02 00
01 79 84. The format analysis is shown in the following table:
Device address
Function code
Starting address Address ID
Checksum
01
03
02
00 01

In the response data, the first byte 01 represents the real address of the current device.
(2) Change the device address
For example, if the current device address is 1 and you want to change it to 02, the command is: 01 06
00 66 00 02 E8 14 .

After the change is successful, the device will return the information: 02 06 00 66 00 02 E8 27. The
format analysis is shown in the following table:

In the response data, after the modification is successful, the first byte is the new device address.
Generally, after the device address is changed, it takes effect immediately. At this time, users need to
modify the query commands in their own software accordingly.
4. Read and modify the baud rate (1) Read the baud rate
The default factory baud rate of the device is 9600. If you need to change it, you can perform the
change operation according to the following table and the corresponding communication protocol. For example, to read the baud rate ID of the current device, the command is: 01 03 00 67 00 01 35 D5 . The
format analysis is as follows.
Device address
Function code
Starting address Data length
Checksum
01
03
00 67

Read the baud rate code of the current device. Baud rate codes: 1 for 2400; 2 for 4800; 3 for 9600; 4
for 19200; 5 for 38400; 6 for 115200.
For a correct query command, the device will respond. For example, the response data is: 01 03 02 00
03 F8 45. The format analysis is shown in the following table:
Device address
Function code
Data length
Baud rate code
Checksum
01
03
02
00 03
F8 45
According to the baud rate code, 03 represents 9600, which means the current baud rate of the device
is 9600.
(2) Change the baud rate
For example, to change the baud rate from 9600 to 38400, that is, change the code from 3 to 5, the
command is: 01 06 00 67 00 05 F8 16 .
Device address
Function code
Register address Target baud rate Checksum
01
06
00 67
00 05
F8 16
Change the baud rate from 9600 to 38400, that is, change the code from 3 to 5. The new baud rate will
take effect immediately. At this time, the device will stop responding, and the query command for the
device’s baud rate needs to be modified accordingly.
5. Read and modify the correction value (valid for some products) (1) Read the correction value
When there is an error between the data and the reference standard, we can reduce the display error by adjusting the “correction value”. The adjustable range of the correction difference is plus or minus 1000,
that is, the value range is 0 – 1000 or 64535 – 65535. For example, when the displayed value is 100 less
than the actual value, we can correct it by adding 100. The command is: 01 03 00 6B 00 01 F5 D6 . In the
command, 100 is the hexadecimal value 0x64. If you need to decrease the value, you can set a negative
value. For example, – 100 corresponds to the hexadecimal value FF 9C. The calculation method is 100 –
65535 = 65435, and then convert it to hexadecimal, which is 0x FF 9C. The device correction value starts
from 00 6B. We take the first parameter as an example for illustration. When there are multiple parameters,
the methods for reading and modifying the correction value are the same.

For a correct query command, the device will respond. For example, the response data is: 01 03 02 00

In the response data, the first byte 01 represents the real address of the current device, and 00 6B is
the register for the correction value of the first state variable. If the device has multiple parameters, the
operation methods for other parameters are the same. Generally, temperature and humidity sensors have
this parameter, while light sensors usually do not.
(2) Change the correction value
For example, if the current state variable value is too small and we want to increase its real – value by
1, the command to correct the current value by adding 100 is: 01 06 00 6B 00 64 F9 FD .

After the operation is successful, the device will return the information: 01 06 00 6B 00 64 F9 FD. After
the change is successful, the parameter takes effect immediately.
For example, the range is 0~30m/s, the analog output is 4~20mA current signal, wind speed and
current The calculation relationship is as shown in the formula: C = (A2 -A1) * (X-B1) / (B2-B1) + A1, where
A2 is wind speed range upper limit, A1 is the lower limit of the range, B2 is current output range upper limit,
B1 is the lower limit, X is the currently read wind speed value, and C is the calculated current value. The list
of commonly used values is as follows:
