Legrand PDU User Guide 123
A DPX2, DPX3, DX or DX2 sensor package has a serial number tag attached to its rear side.
The serial number for each sensor or actuator appears listed in the web interface after each sensor or
actuator is detected by the Legrand PDU. Match the serial number from the tag to those listed in the sensor
table.
Identifying the Sensor Position and Channel
Raritan has developed five types of environmental sensor packages - DPX, DPX2, DPX3, DX and DX2
series. Only DPX2, DPX3, DX and DX2 sensor packages can be daisy chained.
Legrand PDU can indicate where each sensor or actuator is connected on the Peripheral Devices page.
DPX series shows the sensor port number only.
For example, Port 1.
DPX2, DPX3, DX and DX2 series show both the sensor port number and its position in a sensor chain.
For example, Port 1, Chain Position 2.
If a Raritan DPX3-ENVHUB4 sensor hub is involved, the hub port information is also indicated for DPX2,
DPX3, DX and DX2 series, but NOT indicated for DPX series.
For example, Hub Port 3.
If a sensor/actuator contains channels, such as a contact closure sensor or dry contact actuator, the
channel information is included in the position information.
For example, Channel 1.
