Monitoring the incoming power to the DXM IO-Board is a good practice to ensure the power supply for the DXM is supplying sufficient voltage and current, especially if the DXM is powered off a battery (such as a 12 V SLA battery commonly used in solar-powered applications). Note that this is only available on DXM100, DXM150, and DXM1000 models.
From the IO-Board, it is possible to read the following:
- Battery Voltage (mV)
- Battery Charging Current (mA)
- Incoming Supply Voltage (mV, solar or power supply)
- On-Board Thermistor Temperature (°C)
