Note:
1. Sampling Rate: This parameter refers to the acquisition speed of the ADC chip
2. Data Communication Rate: This parameter refers to the communication speed between the MCU controller and the host computer.
Working principle
The upper computer sends MODBUS RTU protocol instructions to the DAM terminal through RS232/RS485/USB/RJ45/WIFI to achieve data acquisition.
