The AC-421 enables easy programming of any SDI-12 sensor by simply connecting the sensor to a computer’s USB port.
Configuration of the sensor can be done using any terminal program or Apogee Instruments DSI software.
One side of the AC-421 features a USB connection for plugging into a computer. The other side of the AC-421 has +12 V out, GND, and SDI-12 data channels for connection to any standard SDI-12 sensor (for proper operation, please connect the ground wire first).
