D-Wire Sensors
The NetGuardian supports up to 16 daisy-chained D-Wire sensors via its D-Wire input. Sensors connected to the
NetGuardian will appear on the web interface. The background color of the ROM field informs the user of the sensor's
configuration state.
Also the NetGuardian's first D-Wire sensor used to monitor the internal temperature. The internal temperature sensor
measures a range of -40° F to 180° F (-40° C to 82.2° C) within an accuracy of about ± 2°.
Basic configuration for the NetGuardian's D-Wire temperature sensors can be accomplished from the
Provisioning
>
Sensors
menu. From this screen, you can configure D-Wire sensors, select notification devices, and set
thresholds.
