Note：
- Sampling rate: This parameter refers to the acquisition speed of the ADC chip. Due to the speed limitation of the RS485 interface, it is impossible to actually output all the sampled data.
- Data communication rate: This parameter refers to the communication speed between the MCU controller and the host computer, which is a theoretical parameter. The actual parameter may not be able to reach this parameter according to the on-site environment.
