Wiring : Default Line : Line Color and Output Signal Red: Voltage and Current: Power positive,  : Power positive Black: A+ Yellow: B- Green: Voltage and Current: Power negative,  : Power negative Description of Sensor Communication Protocol: If you are connecting multiple senso to PLC, configuring or connecting to a programmable data collector, it is recommended to use the standard for -RTU protocol (hex sending and receiving). Standard for  -RTU communication protocol 1. Serial Port Format 8 data bits, 1 stop bit, no parity bit, baud rate 9600bps, the serial port debugging software is set to hex sending and receiving, the interval between two communications is at least 1000ms, the CRC in the manual is the parity bit, 2 words Festival. 2. Register Address The YGC-SM comprehensive soil sensor can integrate up to 8 soil s, namely soil temperature, soil moisture, electrical conductivity, and soil nitrogen, phosphorus and potassium content. Each has its own register address. The correspondence between register addresses and channels in for  is as follows: Register Address and Aisle Data Shows:  0x0000: Channel 1 (TW) Signed number (-40.80 celsius ), 0x7 (invali elsiusmissed) 0x01 0x2C=30.0 celsius 0x0001: Channel 2 (soil wet) Signed number (0.60%), 0x7 (invali elsiusmissed) 0x01 0x23=29.1 0x0002: Channel 3 (conductivity) Signed number (0-20000) usCelsiuscm, 0x7 (invali elsiusmissed) 0x01 0xF4=500usCelsiuscm 0x0005: Channel 6 (nitrogen content) Signed number (0-2000) mgCelsiuskg, 0x7 (invali elsiusmissed) 0x00 0xE1=225 mgCelsiuskg 0x0006: Channel 7 (phosphorus content) Signed number (0-2000) mgCelsiuskg, 0x7 (invali elsiusmissed) 0x00 0x64=100 mgCelsiuskg 0x0007: Channel 8 (potassium content) Signed number (0-2000) mgCelsiuskg, 0x7 (invali elsiusmissed) 0x00 0xA0=160 mgCelsiuskg Troubleshooting : The display value of the instrument is incorrect when the analog signal or is output. Correct data may not be acquired due to wiring problems or communication serial port failures. Please check whether the wiri
