Introduction to Environmental
Sensor Packages
Raritan has four types of environmental sensor packages: DPX, DPX2,
DPX3 and DX series.
DPX series described in this guide refers to DPX sensor packages
instead of DPX power distribution units (PDUs) unless otherwise
specified.
Note that NOT all Raritan products support all types of Raritan
environmental sensor packages. For specific sensor support information,
see the online help of your Raritan EMX, Branch Circuit Monitor (BCM) or
PDU like PX2, PX3 and so on. For a list of Raritan products that support
these environmental sensor packages, refer to Supported Maximum
Number of Sensors and Actuators (on page 63).

Note: Online help is accessible from your Raritan PDU, EMX or BCM
application, or the Raritan website's Support page(http://www.raritan.com/support/).

Chapter 1: Introduction to Environmental Sensor Packages

Sensor Overview
An environmental sensor package may have more than one sensor or
actuator function. For details, see:


Available DPX Sensor Packages (on page 6)
Available DPX2 Sensor Packages (on page 24)
Available DPX3 Sensor Packages (on page 30)
Available DX Sensor Packages (on page 35)

A sensor is used to detect the environmental condition, such astemperature, humidity, and water presence. An actuator is used tocontrol a system or mechanism, such as turning on or off a device.
Depending on the firmware of your Raritan PDU or EMX, the maximum
number of sensors or actuators supported by your PDU or EMX differs.
See Supported Maximum Number of Sensors and Actuators (on page63).
The maximum cabling length for DPX2, DPX3 and DX sensor packages
connected to a Raritan product's sensor port should not exceed 98 feet
(30 meters). For the supported DPX cabling length, see Supported
Maximum Sensor Distance (on page 61).

Exception: DX-PD2C5 supports a maximum cabling length of 29 feet (9 m)
instead of 98 feet (30 m).
Warning: For proper operation, wait for 15~30 seconds between eachconnection operation or each disconnection operation ofenvironmental sensor packages.

you cannot daisy chain multiple DPX2 sensor cables.
(1) The sensor hub that only DPX sensor packages support is
DPX-ENVHUB4.
(2) The sensor hub that all Raritan sensor packages support is
DPX3-ENVHUB4.

Sensor Support GuidelinesThe first generation of Raritan PDUs only supports DPX sensor
packages so do NOT connect other Raritan sensor packages,
including DX, DPX2 and DPX3 sensor packages, to the following
models.
- PX PDUs- DPXS PDUs
- DPXR PDUs
- DPCS PDUs
- DPCR PDUs

All other Raritan PDUs than the above models support all types ofRaritan environmental sensor packages, including DPX, DPX2, DPX3
and DX sensor packages. However, a few DX sensor packages may
be supported by specific Raritan PDUs only. For example, DX-PD2C5(on page 39).
EMX supports all types of Raritan environmental sensor packages,
including DPX, DPX2, DPX3 and DX sensor packages. However, it
may not support a few DX sensor packages, such as DX-PD2C5 (onpage 39).

Chapter 2

DPX Series
DPX is the first generation of Raritan environmental sensor packages.
Most DPX packages come with a factory-installed sensor cable with an
RJ-12 connector.

Chapter 2: DPX Series

DPX Temperature and Humidity Sensors
Raritan provides three types of DPX temperature and humidity sensor
packages: DPX-T1, DPX-T1H1 and DPX-T3H1.
A DPX-T3H1 package contains one DPX-T1H1 and two DPX-T1 sensors.
As shown in the following diagram, all sensors have been connected tothe sensor cable, when shipping out of the factory, in a manner that you
cannot remove or replace any individual sensor.

Air Flow Sensors
If a DPX air flow sensor (DPX-AF1) is connected, make sure the sensor
faces the source of the wind (such as a fan) in the appropriate orientation
as indicated by the arrow on that sensor.

To affix this sensor to an object or place, just screw it up using thesensor's two screw holes.

Chapter 2: DPX Series

Differential Air Pressure Sensors
The DPX differential air pressure sensor (DPX-T1DP1) detects not only
the differential air pressure but also the temperature because it has abuilt-in temperature sensor.
This sensor is designed to receive the inputs of two pressure levels.
Differential air pressure is measured by reading the difference of the two
inputs.

Chapter 2: DPX Series

Connecting Tubes
Two tubes are shipped with the sensor. Connect the tubes to the sensor
to receive two air pressure inputs. If necessary, cut the tubes so that the
tube length meets your needs.
To install tubes:
1.

Connect the tubes to both pressure nozzles of the sensor.

2.

Place each tube's grommet in an appropriate location where youwant to detect differential air pressure levels.
Place the "Lo" tube's grommet in a low air pressure position.

Place the "Hi" tube's grommet in a high air pressure position.

Connecting a DPX Sensor Package to an Air Pressure Sensor
You can add any DPX sensor package to a differential air pressure
sensor.
To connect one DPX to one air pressure sensor:
1.

Use a Raritan-provided phone cable to connect an air pressure
sensor to a Raritan PDU or EMX.
a. Plug one end of the cable into the sensor's "In" port.
b. Plug the other end into a Raritan PDU's or EMX' sensor port.


2.

An RJ-12 to RJ-45 adapter is required if your Raritan PDU uses
an RJ-45 SENSOR port, such as PX3.

Connect one DPX sensor package to the air pressure sensor's "Out"
port.

Chapter 2: DPX Series

It can be any available DPX sensor package shown in the section
titled Available DPX Sensor Packages (on page 6).

Note: You CANNOT cascade more than two sensor packages in this DPX
sensor chain.

Contact Closure Sensors
Raritan's contact closure sensor (DPX-CC2-TR) can detect the
open-and-closed status of connected detectors/switches.
This sensor has two channels for connecting two discrete (on/off)detectors/switches. Four termination points are available: the two to theright are associated with one channel (as indicated by the sensor's LED
number), and the two to the left are associated with the other.

NumberComponent
Two LEDs for indicating two channels' status.
Four termination points for connecting two discrete
detectors/switches.

10Chapter 2: DPX Series

Supported detector/switch types:
At a minimum, a discrete detector/switch is required in order for
DPX-CC2-TR to work properly. The types of discrete detectors/switches
that can be connected to DPX-CC2-TR include those for:






Door open/closed detection
Door lock detection
Floor water detection
Smoke detection
Vibration detection

Raritan does NOT produce most of the above detectors/switches except
floor water sensors. When using third-party probes, you must test themwith DPX-CC2-TR to ensure they work properly.
Important: Integration and testing for third-party detectors/switches
is the sole responsibility of the customer. Raritan cannot assume
any liability as a result of improper termination or failure (incidental
or consequential) of third-party detectors/switches that customers
provide and install. Failure to follow installation and configuration
instructions can result in false alarms or no alarms. Raritan makes
no statement or claim that all third-party detectors/switches will
work with DPX-CC2-TR.
Connection scheme:
A DPX-CC2-TR can connect two contact closure detectors/switches.

For details on connecting a detector/switch, see Connecting
Detectors/Switches to New DPX-CC2-TR (on page 12) or Connecting
Detectors/Switches to Old DPX-CC2-TR (on page 14).

11

Chapter 2: DPX Series

Old and New Contact Closure Sensors
Since the end of 2012 Raritan provided a new contact closure sensor. Old
and new contact closure sensors are functionally identical with thefollowing exceptions.
The old sensor type uses buttons to secure or loosen the connectionof detectors/switches while the new type uses screws.
The new sensor type's terminals can be separated from the sensor
but the old type's terminals are fixed.
The new sensor type supports Raritan's DPX water sensors(DPX-WSC and DPX-WSF) but the old type does NOT.

Both old and new contact closure sensors share the same part number:
DPX-CC2-TR.
The latest firmware for your Raritan PDU or EMX will continuously
support the old DPX-CC2-TR.
For instructions on new contact closure sensors, see Connecting
Detectors/Switches to New DPX-CC2-TR (on page 12).
For instructions on old contact closure sensors, see Connecting
Detectors/Switches to Old DPX-CC2-TR (on page 14).

Connecting Detectors/Switches to New DPX-CC2-TR
The new DPX-CC2-TR comprises two parts: sensor box and terminal
module. The terminal module is detachable so it is more convenient toconnect/disconnect discrete detectors/switches.
Below are the resistance values for the new DPX-CC2-TR to open andclose a connected detector/switch reliably.


Open: Greater than 320K ohm
Closed: Less than 200K ohm
To make connections when the terminal module is attached:

1.

Strip the insulation around 12 mm from the end of each wire of
discrete detectors/switches.

2.

Fully insert each wire of both detectors/switches into eachtermination point.


12

Plug both wires of a detector/switch into the two termination
points to the left.

Chapter 2: DPX Series

3.

Plug both wires of the other detector/switch into the twotermination points to the right.

Use a screwdriver with a 2.5 mm wide shaft to tighten the screws
above each termination point to secure the wires, using a torque of0.196 N·m (2 kgf·cm).

To make connections after the terminal module is separated:
You can also connect a detector/switch when the terminal module isseparated from the sensor box.
1.

Loosen the screws at two sides of the terminal module.

13

Chapter 2: DPX Series

Note: The two screws are not removable so just loosen them.

2.

Separate the terminal module from the sensor box.

3.

After connecting detectors/switches to the terminal module, plug theterminal module back into the sensor box, and then tighten thescrews at two sides of the terminal module.

Connecting Detectors/Switches to Old DPX-CC2-TR
The old DPX-CC2-TR has four spring-loaded termination points and four
little buttons to control the spring of each termination point.
To connect third-party or Raritan's discrete detectors/switches:
1.

14Strip the insulation around 12 mm from the end of each wire of
discrete detectors/switches.

Chapter 2: DPX Series

2.

Press and hold down the tiny rectangular buttons above thetermination points on DPX-CC2-TR.

3.

Fully insert each wire of both detectors/switches into eachtermination point.


Plug both wires of a detector/switch into the two termination
points to the left.



Plug both wires of the other detector/switch into the twotermination points to the right.

4.

Release the tiny rectangular buttons after inserting the wires
properly.

5.

Verify that these wires are firmly fastened.

Configuring a Contact Closure Sensor
Before using DPX-CC2-TR to detect contact closure status, water, smoke
or vibration, you must determine the normal state by adjusting its dip
switch. The dip switch controls the LED state on DPX-CC2-TR, and isassociated with a channel.
To adjust the dip switch setting:1.

Place the detectors/switches connected to DPX-CC2-TR to theposition where you want to detect a specific environmental situation.

2.

Uncover the dip switch on DPX-CC2-TR.
New DPX-CC2-TR

15

Chapter 2: DPX Series

3.

To set the Normal state for channel 1, locate the dip switch labeled
1.

4.

Use a pointed tip such as a pen to set the slide switch to the position
labeled N.O or N.C.


N.O (Normally Open): The open status of the connected
detector/switch is considered normal.



N.C (Normally Closed): The closed status of the connected
detector/switch is considered normal.

For Raritan's DPX water sensors, the Normal state must be
Normally Open, which indicates there is no water detected. Set the
dip switch to Normally Open and verify that the LED of the channel
where the Raritan's water sensor is connected remains OFF.

To set the Normal state for channel 2, repeat Step 4 for adjusting theother dip switch's setting.

Chapter 2: DPX Series

6.

Install back the dip switch cover.

Note: The dip switch setting must be properly configured, or the sensor's
LED may be incorrectly lit in the Normal state.
Contact Closure Sensor LEDs
Description in this section applies to LEDs of DPX-CC2-TR and those of
DX contact closure sensor channels. See DX Series (on page 34).
LEDs indicate states of detectors/switches connected to the contact
closure sensor channels.
The LED is lit when the associated detector/switch enters the "alarmed"
state. See Configuring a Contact Closure Sensor (on page 15) for how
to set the Normal state of DPX-CC2-TR.
The meaning of a lit LED varies depending on the Normal state settings.

Floor Water Sensors
Raritan has two types of DPX floor water sensors that work in
conjunction with Raritan's new contact closure sensor (DPX-CC2-TR).
One is the floor-mounted water sensor (DPX-WSF), and the other is thecable water sensor (DPX-WSC series).
Note that only the NEW DPX-CC2-TR support these water sensors.

Note: If you order a Raritan DPX water sensor with the part number
containing the suffix -KIT, you get the new DPX-CC2-TR that supports it.
Floor-mounted Water Sensor
The floor-mounted water sensor (DPX-WSF) has a flat bottom so it canstand on the ground. The water detector's dimension is 63.5 mm x 13.25mm x 13.2 mm (W x L x D).
Use one of the following methods to affix this detector to the ground:

Screw the detector to the ground with your own screws. To avoid
breaking the detector's enclosure, do not over tighten the screws.
Put something weighing around 100 to 250 grams (0.22 to 0.55
pounds) into the empty bag shipped with this water sensor. Then use
cable ties to wrap the bag right above the detector. Make sure thedetector is not tilted so that its bottom evenly contacts the ground.

NumberItem

Chapter 2: DPX Series

NumberItem
Wires to connect to the contact closure sensor.
You need a minimum of 30 cm wires to prevent thecontact closure sensor from being damaged by floor
water (if any). Below are the wire length limitations:

Minimum: 30 cm (11.8 inches)
Maximum: 150 cm (59 inches)

How a Floor-mounted Water Sensor Works

The floor-mounted water sensor uses two poles marked with red arrows
below to detect the water.

When there is some water between the two poles, it causes current loop
back on the water sensor to trigger the alarm.

19

Chapter 2: DPX Series

Cable Water Sensor
The cable water sensor is in the shape of a cable so it can be flexibly
placed, twisted or wrapped around a location where water may drip,
such as a ceiling tile, water pipe or the floor.
Raritan provides two types of cable water sensors. The only difference istheir cable length.

Minimum: 30 cm (11.8 inches)
Maximum: 150 cm (59 inches)Chapter 2: DPX Series

How a Cable Water Sensor Works

The cable water sensor uses black wires on the water rope to detect thewater. When there is water between two black wires, it causes current
loop back to trigger the alarm on the water sensor.

Mechanical information about black wires:
The distance between two black wires is about 0.3 in.
The distance from the black wire to the cable surface is about 0.05
in.

Water detection requirements:
The water spot should be at least 0.5" wide so that two black wires
are in the water at the same time. Otherwise, the water cannot cause
current loop back on the water sensor to trigger the alarm.
If the water spot is about 1" wide, the water sensor should detect it at
any location of the water rope.

The thickness of the water spot should be at least 0.1" because there
is some gap between any black wire and the cable surface.
This is why the cable water sensor does NOT work well with theconcrete floor but works fine with ceramic tiles. The concrete floor
absorbs the water quickly so it needs more water on the concrete
floor to trigger the alarm.

21

Chapter 2: DPX SeriesThe alarm requires some water between two black wires for a while.
If there are just few water drops on the cable water sensor, noalarms are triggered.
The water sensor's rope should be mounted on the floor firmly, or
the water sensor cannot detect the water.
In the following diagram, NO alarm is triggered by the presence of
the water, which is indicated by the blue color, because the water
sensor's rope does not evenly contact the floor.

22

Chapter 3

DPX2 Series
DPX2 sensors are physically similar to DPX sensors. Below are theirdifferences:







DPX2 does not have a factory-installed sensor cable so you must
manually connect DPX2 sensors to a DPX2 sensor cable.
DPX2 has an LED to show the sensor status.
DPX2 provides the chain position information.
Individual DPX2 sensors can be replaced without the need toreconnect the DPX2 sensor cable.
DPX2 does NOT support the use of a Raritan DPX-ENVHUB4 sensor
hub.
DPX2 can be connected to the end of a DX sensor chain while DPX
sensor packages CANNOT. For details, see Connecting a DPX2
Sensor Package to DX (on page 53).

Connection and Disconnection
Before connecting a DPX2 sensor to a Raritan PDU or EMX, you must
connect it to a DPX2 sensor cable first.
If any connected sensor is broken, you can replace it with a new one
without disconnecting the DPX2 sensor cable from the Raritan PDU or
EMX.
To connect the DPX2 sensor package to the end of a DX sensor chain, seeConnecting a DPX2 Sensor Package to DX (on page 53).

Chapter 3: DPX2 Series

Connecting a DPX2 Sensor Cable
Raritan has three types of DPX2 sensor cables. The difference is thenumber of available head connectors on the cable: one to three head
connectors.
DPX2 sensor cables cannot be daisy chained.
The following diagram illustrates a DPX2 sensor cable with three head
connectors.

27

Chapter 3: DPX2 Series

Sensor connection guidelines:
Always make sure there are NO free head connectors between thesensor cable's RJ-12 connector and the final DPX2 sensor attached to it.
That is, each head connector prior to the final DPX2 sensor must be
occupied with a sensor. Otherwise, those sensors following the "free"head connector(s) on the same sensor cable do not work properly.
Below illustrates the scenarios when the number of DPX2 sensors is lessthan the number of head connectors on a DPX2 sensor cable.

28



Scenario A: When only one sensor is connected, always connect it to
the first head connector.



Scenario B: When only two sensors are connected, always connect
them to the first two head connectors.

Chapter 3: DPX2 Series

Disconnecting a DPX2 Sensor
You can remove any individual DPX2 sensor from the sensor cablewhenever needed.
To disconnect a DPX2 sensor:
1.

Press the latch of the cable connector so that the other side of thelatch slightly goes up.

2.

Pull the sensor away.

3.

Connect any DPX2 sensor back to this free head connector, or move
all subsequent DPX2 sensors that follow it on the same sensor cableto prior head connectors.

Warning: The final step is required, or all subsequent DPX2 sensors
no longer work properly. For example, after removing the sensor fromthe 2nd head connector, you must either add a DPX2 sensor back to
the 2nd head connector, or move the sensor attached to the 3rd head
connector to the 2nd head connector.

Making Connections
Cascading DPX3 Sensor Packages
To increase the number of connected DPX3 sensor packages per
SENSOR port, you can cascade DPX3 using standard network patch
cables (CAT5e or higher). Up to 12 DPX3 sensor packages can be daisy
chained.

Tip: You can also make a sensor chain comprising DPX3 and DX sensor
packages. See Cascading DPX3 and DX Sensor Packages (on page 55).
To cascade DPX3 sensor packages:
1.

Connect a standard network patch cable to either RJ-45 port of thefirst DPX3 sensor package.

Note: For a Raritan EMX or PDU with the RJ-12 SENSOR port, use
the RJ-12 to RJ-45 adapter cable instead.
2.

If you want to cascade DPX3 sensor 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 theprior DPX3.
b. Plug the other end into either RJ-45 port on an additional DPX3.
Repeat the same steps to cascade more DPX3 sensor packages.

32Chapter 4: DPX3 Series

3.

Make sure the total number of cascaded sensors does not exceed
the maximum number of sensors supported per sensor port. See
Supported Maximum Number of Sensors and Actuators (on page63).

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.

DX Series
A DX sensor package consists of terminals, sensors and two RJ-45 ports.
Different DX sensor packages have a different number of terminals.
Every pair of terminals is a channel for connecting a sensor or actuator.
Contact closure channels on DX do not support Raritan's DPX water
sensors.

Note: DX may also not support third-party leakage detectors so you must
test them before using any third-party leakage detectors.
No sensor cables are shipped with DX sensor packages except for an
RJ-12 to RJ-45 adapter cable (part number: 254-01-0032-00).
A standard network patch cable (CAT5e or higher) is needed to:Connect a DX sensor to a Raritan product with the RJ-45 SENSOR
port, such as PX3 PDU.

Exception: For a Raritan EMX or PDU with the RJ-12 SENSOR port,
use the RJ-12 to RJ-45 adapter cable instead which is shipped withDX.
Daisy chain DX sensor packages.

DX-PIR
DX-PIR contains one occupancy sensor (that is, presence detector), one
tamper sensor and a pair of terminals for connecting a contact closure(CC) sensor.

Occupancy sensor:
The occupancy sensor is located on the top of the DX-PIR. It uses thepassive infrared technology to detect the motion of a person by sensing
the temperature differences between a person and the surroundings.

The diagrams below show the occupancy sensor's detection range andsensing area.

Conditions for the detected target:

Temperature difference between the target and the surroundings
should exceed 4 degrees Celsius (7.2 degrees Fahrenheit).
Target's movement speed: 1.0 m/s.
Target concept is human body (size: 700 x 250 mm).
Tamper sensor:

The tamper sensor is located on the back of the DX-PIR. This sensor isused to detect whether the DX-PIR is moved away from its original
position. In the normal state, the DX-PIR is firmly affixed to an object so
this sensor, which is a button on the back of DX-PIR, is pressed down. If
someone takes the DX-PIR away, the button springs up so the sensor isin the alarmed state.

Making Connections
Pre-installed DX Brackets
To allow users to hang or affix a DX onto an object or position, twobrackets have been installed on the rear side of a DX sensor package
when shipped out of the factory.
Below is the diagram of a DX sensor package with two brackets installed.

Connecting Detectors/Actuators to DX
A DX sensor package comprises two parts: a sensor box and the terminal
module(s). A terminal module is removable.

Note: The following diagrams illustrate a terminal module comprising
two termination points only. Your DX terminal module may be larger if it
has more terminals.
To make connections when the terminal module is attached:
1.

Strip the insulation around 12 mm from the end of each wire of adetector or actuator.


2.

Wire size range: AWG 28 to 20 or 0.09 to 0.5 mm2

Fully insert each wire into each termination point of a CC, DC or PDC
channel on the DX sensor package.

49

Chapter 5: DX Series

Important: For a PDC channel, you must check the electrical polarity
markings (+ and -) on the DX label to make sure each wire isinserted into the correct termination point with the correct polarity.

3.

Use a screwdriver with a 2.5 mm wide shaft to tighten the screws
above each termination point to secure the wires, using a torque of0.196 N·m (2 kgf·cm).

To make connections after the terminal module is detached:
1.

Loosen the screws at two sides of the terminal module.

Note: The two screws are not removable so just loosen them.

50

Chapter 5: DX Series

2.

Separate the terminal module from the sensor box.

3.

After connecting detectors/switches to the terminal module, plug theterminal module back into the sensor box, and then tighten thescrews at two sides of the terminal module.

Cascading DX Sensor Packages
To increase the number of connected DX sensor packages per SENSOR
port, you can cascade DX using standard network patch cables (CAT5e or
higher). A maximum of 12 DX sensor packages can be daisy chained.

Tip: You can also make a sensor chain comprising DPX3 and DX sensor
packages. See Cascading DPX3 and DX Sensor Packages (on page 55).

Adjusting Dip Switches
There are two Normal settings for each CC channel on DX packages.


N.O (Normally Open): The open status of the connected
detector/switch is considered normal.
N.C (Normally Closed): The closed status of the connected
detector/switch is considered normal.

Each CC channel and the DX-PIR occupancy sensor's Normal setting is
configured by turning on or off its corresponding dip switch.

Appendix A Supported Maximum Sensor
Distance
DPX2, DPX3 and DX sensor package support the total cabling length up
to 98 feet (30 m), except for DX-PD2C5 (on page 39).
As for DPX sensor packages, the 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.
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 and DX.

Each sensor port on a Raritan PDU or EMX supports only one Raritan
sensor hub so DO NOT cascade sensor hubs.
DPX sensor connection restriction and illustration :Restriction: When using a DPX-ENVHUB4 sensor hub, the maximum
cabling distance between the PDU/EMX/BCM 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' (5 m).



The total cabling length between the PDU/EMX/BCM and one
DPX-T3H1 is 49' (15 m) as illustrated below.
Note that the length 16' (5 m) is the length of each DPX-T3H1 sensor

Appendix B Supported Maximum Number of
Sensors and Actuators
The maximum number of sensors and actuators that can be managed
per sensor port of a Raritan PDU or EMX varies according to the PDU's
or EMX' firmware version.
However, DPX sensor packages are always limited to a maximum of 16
DPX sensors per port due to hardware restrictions regardless of thefirmware version.
Below lists different Raritan products and firmware versions that
support a different number of managed sensors/actuators.

Note: For the latest information on the supported maximum number of
sensors and actuators, see the online help of your Raritan PDU or EMX.
Online help is accessible from your Raritan PDU, EMX or BCM
application, or the Raritan website's Support page(http://www.raritan.com/support/).
In the following list, x represents a number.

Manage up to 16 sensors/actuators per port:
PX2 series: 2.5.x and earlier
PX3 series: 2.5.x
PX3TS series: 2.6.x
EMX series: 2.5.x and earlier
BCM series: 2.5.x and earlier
PXE series: 2.5.x and earlier
PX, DPC and DPX (PDU) series: 1.5.x and earlier

Note: PX, DPX and DPC PDUs support DPX sensor packages only.

Manage up to 32 sensors/actuators per port:
PX2 series: 3.0.0 and later
PX3 series: 3.0.0 and later
PX3TS series: 3.0.0 and later
EMX series: 3.1.0 and later
BCM series: 3.0.0 and later
PXE series: 3.0.0 and later
Calculation examples for 16 and 32 sensors/actuators:

A sensor package may contain more than one sensor/actuator. A sensor
or actuator is a function. For example, a DX-D2C6 contains 8 functions
because it has 6 sensors and 2 actuators.

63

Appendix B: Supported Maximum Number of Sensors and Actuators

When a Raritan PDU or EMX supports 16 managed sensors or
actuators:
2*8 = 16
Therefore, you can manage two DX-D2C6 packages per port.

When a Raritan PDU or EMX supports 32 managed sensors or
actuators:
4*8 = 32
Therefore, you can manage four DX-D2C6 packages per port.
Tip for DX sensor connection:

If intended, you can connect a maximum of 12 DX sensor packages
without exceeding the maximum number of sensors/actuators supported
by your EMX or PDU. All you need to do is to manage "partial"
sensors/actuators of each DX and unmanage the rest.
For example, if your EMX or PDU can manage 32 sensors/actuators perport, you can connect 12 DX-D2C6 sensor packages to a sensor port bymanaging only two sensors or actuators of each DX-D2C6.
12*2 = 24
All 24 sensors/actuators can be managed because it is less than 32.
For information on how to manage and unmanage any sensors/actuators,
see online help or User Guide of your PDU or EMX.

Appendix C Sensor Measurement Accuracy
This section shows the factory specifications of Raritan DPX and DPX2
environmental sensor packages. Calibration is not required for thesesensor packages.

In This Chapter
DPX Sensor Accuracy ................................................................................ 65
DPX2 Sensor Accuracy .............................................................................. 65

DPX Sensor AccuracyTemperature: +/-2 degrees Celsius (+/-3.6 degrees Fahrenheit)
Humidity: +/-5% (when humidity < 60%) or +/-8% (when humidity >60%)
Differential air pressure: +/-1.5%
Air flow: +/-6.5%

DPX2 Sensor AccuracyTemperature: +/-1.0 degree Celsius (+/-1.8 degrees Fahrenheit)
Humidity: +/-2.5% (when humidity = 10% to 90%)65

Appendix D Sensor Firmware Update
DPX2, DPX3 and DX sensor packages automatically upgrade or
downgrade their firmware after being connected to a Raritan EMX or
PDU that supports these sensor packages. This way it ensures that thesesensor packages work properly with the connected Raritan PDU or EMX.
Automatic upgrade or downgrade is determined by comparing DPX2,
DPX3 or DX sensor firmware against the environmental sensor firmware
stored inside the Raritan PDU or EMX. A downgrade can be performed
only when the PDU- or EMX-provided sensor firmware is either greaterthan or equal to the minimum firmware version requested by theconnected sensor packages.
Note that a DPX sensor package does NOT support the automatic
firmware update feature, and you do NOT need to manually update it.

Tip: Information regarding current sensor firmware version and thesensor's firmware update time is available in the Device Information
dialog. Choose Maintenance > Device Information > Peripheral Devices in
the web interface of your Raritan PDU or EMX.

Appendix E Sensor Naming Conventions
The model name of a Raritan environmental sensor package consists ofsensor family, sensor functions and the total number of the specified
function.
[Family] - [Function_1] [Number_1]- OR [Family] - [Function_1] [Number_1] [Function_2][Number_2][Family] is DPX, DPX2, DPX3 or DX.
[Number_1] and [Number_2] are integer numbers.
[Function_1] and [Function_2] are abbreviations representing diverse
functions.

Note: Some sensor packages may indicate the main function only rather
than indicating all functions in its name. For example, the name of
DX-VBR indicates that it contains the vibration sensor while it does notindicate the contact closure sensor that it also contains.
