Legrand PDU User Guide 139
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
.
Sensor/actuator position examples:
Example
Physical position
Port 1
Connected to the sensor port #1.
Port 1,
Channel 2
Connected to the sensor port #1.
The sensor/actuator is the 2nd channel of the sensor package.
Port 1,
Chain Position 4
Connected to the sensor port #1.
The sensor/actuator is located in the 4th sensor package of the sensor chain.
Port 1,
Chain Position 3,
Channel 2
Connected to the sensor port #1.
The sensor/actuator is located in the 3rd sensor package of the sensor chain.
It is the 2nd channel of the sensor package.
Port 1,
Chain Position 1,
Hub Port 2,
Chain Position 3
Connected to the sensor port #1.
Connected to the 2nd port of the DPX3-ENVHUB4 sensor hub, which shows
the following two pieces of information:
The hub's position in the sensor chain -- "Chain Position 1"
The hub port where this particular sensor package is connected -- "Hub
Port 2"
The sensor/actuator is located in the 3rd sensor package of the sensor chain
connected to the hub's port 2.
