Note: Make sure the wiring is correct before sending power.
Communicating Protocol:
All s in the manual of weather meter are RTU protocol format s. All have been configured at the factory, if you need to modify the protocol, refer to the relevant s or ask for help. Baud rate 9600, 8 data bits, 1 stop bit, no check. 2 frames of data communicating interval of at least 500ms. The default address is 1, and the RTU communicating format is as follows:
Number of address bytes: 1 byte
Number of bytes: 1 byte
Number of register address bytes: 2 bytes
Number of data bytes: N bytes
Number of CRC check bytes: 2 bytes
I.Register address:
The weather meter can integrate five modes, namely wind speed, wind direction, temperature, humidity, and atmospheric pressure. Each sensor has its own register address.
II.Configuration address and baud rate:
The s to write the device address are the same for the weather meter.
III.CRC verification steps:
1. Preset the 16 bit register to hex FFFF, call this register the CRC register
2. Isolate the fi t 8-bit data with the lower bit of the CRC register, and put the result in the CRC register
3. Check the lowest bit by ing the contents of the register one bit to the right (toward the lower bit) and filling the highest bit with a 0
4. If the lowest bit is 0: repeat step 3 ( again) if the lowest bit is 1: the CRC register is iso orthogonal to the polynomial A001 (1010 0000 0000 0001)
5. Repeat steps 3 and 4 until it is ed right 8 times so that the entire 8 bit data is all processed
6. Repeating steps 2 through 5 for the other 8 bit data
7. The final CRC register obtained is the CRC (the CRC obtained is low before high).
