DX or DX2 Sensor Packages
DX2 sensor packages, which WILL be released one by one in 2018, are functionally similar to DX or
DPX3 sensor packages. Description in this section applies to all DX and DX2 sensor packages unless
otherwise specified.
Most DX sensor packages contain terminals for connecting detectors or actuators. For information on
connecting actuators or detectors to DX terminals, refer to the Environmental Sensors and Actuators Guide
(or Online Help) on Raritan website's
Support page

You can cascade up to 12 DX sensor packages.
When cascading DX, remember that the Legrand PDU only supports a maximum of 32 sensors and/or
actuators.
If there are more than 32 sensors and/or actuators connected, every sensor and/or actuator after the 32nd
one is NOT managed by the Legrand PDU.
For example, if you cascade 12 DX packages, and each package contains 3 functions (a function is a sensor
or actuator), the Legrand PDU does NOT manage the last 4 functions because the total 36 (12*3=36)
exceeds 32 by 4.
Tip: To manage the last 4 functions, you can release 4 "managed" sensors or actuators, and then manually
bring the last 4 functions into management. See

RJ-45 ports, each of which is located on
either end of a DX sensor package.
RJ-12 port, which is reserved for future use
and now blocked.
Removable rackmount brackets.
Note: A DX2 sensor does not have the RJ-12 port and looks slightly different from the above image. For
details, refer to the Environmental Sensors and Actuators Guide (or Online Help).
Connect DX sensor packages to the Legrand PDU:
1. Connect a standard network patch cable (CAT5e or higher) to either RJ-45 port on a DX sensor
package.
2. If you want to cascade DX packages, get an additional standard network patch cable (CAT5e or higher)
and then:
a. Plug one end of the cable into the remaining RJ-45 port on the prior DX package.
b. Plug the other end into either RJ-45 port on an additional DX package.
Repeat the same steps to cascade more DX packages.
