D-Wire Sensor Inputs

The port on your NetGuardian labeled D-Wire supports up to 16 D-Wire sensors. Your NetGuardian powers
and communicates with your D-Wire sensors via simple RJ-11 connection.
The max cable length depends on the number of sensors daisy chained together. The cable lengths and
corresponding number of sensors can be seen in the table below.

Note: The DPS Temperature and Humidity Sensor, DPS part number D-PK-DSNSR-12002, occupies two nodes.

6.7.1 Connecting to D-Wire Sensors

Using a standard 6P4C, straight-through RJ-11 cable (part number D-PR-045-10A-01, pinout below),
connect the D-Wire port on the NetGuardian to the In jack on the D-Wire Sensor. Chain additional sensors to the
D-Wire sensor (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).
For details about configuring your sensors through the web interface see the Sensors section of this web browser
user manual.
