Integrated Temperature And Battery Sensor (Optional); Analog Polarity Override - DPS Telecom NetGuardian 420 Hardware User Manual

Reference 1 and reference 2 correspond to the minimum and maximum output values of your analog device

13.3.12.1 Integrated Temperature and Battery Sensor (Optional)

The optional integrated temperature and battery sensor allows the user to monitor surrounding temperature as well
as the unit's current draw. This is only available if the NetGuardian was purchased with this option. If you are
using the temperature or battery sensor, you must dedicate an analog port to each one (see user manual for
connection information).
CAUTION: Ambient room temperature will be cooler than the NetGuardian integrated temperature.
