Communicating Protocol:
I. All commands in the manual of weather meter are RTU protocol format commands. All have been configured at the factory, if you need to modify the protocol, refer to the relevant commands 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 command bytes: 1 byte
Number of register address bytes: 2 bytes
Number of data bytes: N bytes
Number of CRC check bytes: 2 bytes
II. CRC verification steps:
1. Preset the 16 bit register to hex FFFF, call this register the CRC register
2. Isolate the first 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 shifting 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 (shift 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 shifted 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 code (the CRC code obtained is low before high).
Troubleshooting:
The meter displays an incorrect value when RS485 is output. The meter may not be able to acquire data correctly due to wiring problems or communicating serial port failure. Please check whether the wiring is correct and firm, whether the serial port is occupied, and whether the serial port setting is correct.
Package List:
1 x Weather Environment Sensor
Note:
1. Please check if the packaging is intact and verify if the product model matches the selection
2. Do not wire with power, only power on after checking the wiring is correct
3. The sensor is a precise device, users should not disassemble, contact the sensor surface with cutting objects or corrosive liquids when using, to avoid damaging the product
4. Ensure that the installation environment does not interfere with the sensor by other running devices, which may not fully with universal standards, such as radioor radar transmitters, ship engines, engines, etc.
5. Do not install on the same plane as any radar scanning device, at least 2 meters away
6. Avoid eddies generated by surrounding buildings such as trees, power poles, high rise buildings, which will affect the accuracy of the product
7. The magnetic north indicated by the compass and the geographic north are not completely consistent, so when calibrating the sensor, the deviation (error) of the location must be considered. The error is related to the location, with the maximum error exceeding 15° (e.g. northeast). In the China region, the error can be neglected (<3°). More detailed information can be found on the Internet.
8. The sensor is a precise instrument, handle with care, do not knock.
