D-Wire Sensor Input (analogs)

The port on your NetGuardian labeled "D-Wire" supports up the connection of up to 16 chained D-Wire
analog sensors. The NetGuardian powers and communicates with your D-Wire sensors via straight-
through RJ-11 cables.
Connecting D-Wire Sensors
Using a 6P4C, straight-through RJ-11 cable, connect the D-Wire sensor port on the NetGuardian to
the In jack on a D-Wire sensor. Chain additional sensors to the NetGuardian (using the same straight-
through cables) from the Out jack on the previous sensor to the In jack on the next (i.e. Out on sensor 4
to In on sensor 5).
Note: Some sensors may consume 2 of your NetGuardian's 16 analog channels (the combined temp/
humidity sensor, D-PK-DSNSR-12002, for example). Your NetGuardian can provide power to a sensor
chain up to 800 feet long.
The Integrated temperature build option uses one of the maximum 16 sensors that are supported.
The D-Wire line of sensors includes temp/humidity, additional analogs, discretes, and more. Contact
DPS at 1-800-693-0351 for information about available D-Wire sensors.
For details about configuring your sensors though the web interface, see the Sensors section of this
manual.
