  • Collection function of IOT Cellular Modem

  • Collect analog standard signals such as pressure and water level transmitters, 4-20mA signals (default);
    Collect data from 485 meters such as flow meters and electricity meters;
    Support fixed-point/timing acquisition, freely configure acquisition/frequency
    Incompatible instrument protocols can be instrument-driven development
