Connecting Environmental Sensors (Optional)
To enable Dominion PX to detect environmental conditions, connect one
or more Raritan environmental sensors to the Dominion PX device.
The maximum distance for all sensor cabling plugged into the product's
sensor port should not exceed 30 meters/100 feet. Contact Raritan
Technical Support if you have questions.
You can connect up to 16 environmental sensors to a Dominion PX device
by using a Raritan sensor hub.
A DPX-T2H2 counts as 4 sensors. A DPX-T3H1 counts as 4 sensors.
Warning: For proper operation, wait for 15~30 seconds between each
connection operation or each disconnection operation of environmental
sensors.
To directly connect one or multiple environmental sensors:
 Plug the connector of the environmental sensor into the SENSOR port
on your Dominion PX device.
Note: Depending on the model you purchased, the number of
SENSOR ports varies.
To connect environmental sensors via an optional PX sensor
hub:
1. Connect a Raritan sensor hub to the Dominion PX device.
a. Plug one end of the Raritan-provided phone cable (4-wire, 6-pin,
RJ-12) into the IN port (Port 1) of the hub.
b. Plug the other end into the SENSOR port on the Dominion PX
device.
2. Connect Raritan environmental sensors to any of the four OUT ports
on the hub.
