D-Wire Sensor Input (analogs)
6.7
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).
Pinout for D-Wire RJ-11 jack s
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.
