NOTE!!!
The K thermocouple acquisition port is easily damaged, please do not input a voltage greater than 3V, and please prevent static electricity. If the acquisition port is damaged, it can be repaired by replacing the MAX6675ISA+/MAX31855KASA+ IC.
How to use:1 Connect the power port to the power supply (DC 12V recommended)
2 Connect to RS485 bus
3 Connect the K thermocouple probe
4 Power-on test
Note: The module will restore factory settings and automatically restart after the RES port is short-circuited for 5 seconds.
For protocol details, please refer to the ''N4KTF32 Modbus RTU Protocol''
All states are mapped into 4xxxx range registers. The user can monitor the input and output status of the module by reading or modifying the value of the 4xxxx interval register (03 06 16 function code)
