Appendix A: Supported Maximum Sensor Distance
75
Raritan sensor hubs:
A sensor hub is used to increase the total distance of a sensor package.
There are two sensor hubs: DPX-ENVHUB4 and DPX3-ENVHUB4.
Different sensor hubs support different sensor packages:
DPX-ENVHUB4 supports the DPX sensor packages only.
DPX3-ENVHUB4 supports all Raritan sensor packages, including
DPX, DPX2, DPX3, DX and DX2.
Each sensor port on a Raritan or Legrand product, such as a PDU,
supports only one Raritan sensor hub so DO NOT cascade sensor hubs.
DPX series:
DPX series' supported distance is determined by the length of the sensor
cable pre-installed (or provided) by Raritan. DO NOT extend or modify the
cabling length with any tool other than Raritan's sensor hubs.
DPX connection restriction and illustration:
When using a DPX-ENVHUB4 sensor hub, the maximum cabling distance
between the Raritan or Legrand product (such as a PDU) and the sensor
hub is 33 feet (10 m).
The following illustrates the maximum distance when connecting DPX
sensor packages with a maximum 16 feet (5 m) sensor cable via a
DPX-ENVHUB4 sensor hub.
The sum of a DPX-T3H1 sensor cable's length is 16 feet (5 meters).
The total cabling length between the Raritan or Legrand product and
one DPX-T3H1 is 49 feet (15 meters) as illustrated below.
Note that the length 16 feet (5 meters) is the length of each
DPX-T3H1 sensor cable, which is defined in the above diagram.
