46 Legrand PDU User Guide
Repeat the same steps to cascade more DPX3 sensor packages.
3. Connect the first DPX3 sensor package to the Legrand PDU by plugging its cable's connector into the
RJ-45 SENSOR port of the Legrand PDU.
Connecting a DPX2 Sensor Package to DPX3
You can connect only one DPX2 sensor package to the "end" of a DPX3 sensor chain. It is strongly
recommended to use an RJ-12 to RJ-45 adapter for connecting the DPX2 to the final DPX3 in the chain.
The maximum number of DPX3 sensor packages in the chain must be less than 12 when a DPX2 sensor
package is involved.
When connecting a DPX2 sensor package containing three DPX2 sensors:
A maximum of nine DPX3 sensor packages can be cascaded because 12-3=9.
When connecting a DPX2 sensor package containing two DPX2 sensors:
A maximum of ten DPX3 sensor packages can be cascaded because 12-2=10.
When connecting a DPX2 sensor package containing one DPX2 sensor:
A maximum of eleven DPX3 sensor packages can be cascaded because 12-1=11.
