DX Sensor Installation Guide
This installation guide offers general instructions on identifying the components on a DX sensor package, and how toinstall it.
For detailed information on each sensor package, download the Environmental Sensors Guide from Raritan website's
PX2 Support Files page (https://www.raritan.com/support/product/px2/px2-support-files). For software functions,access online help from your Raritan PDU or EMX application, such as PX2, PX3 or EMX online help, or from theRaritan website's Support page (http://www.raritan.com/support/).

Overview
A DX sensor package usually has 4 types of components.
They are:
1.
2.
3.
4.

Two RJ-45 ports
Terminals
Dip switches
LED indicator(s)Depending on the DX sensor package you purchased, yourDX may have more terminals, dip switches and LED
indicators than the above diagram.

Installing a DX sensor package involves three steps:
Step 1: Identify Terminals (on page 1)

To identify terminal types using the terminal label:
1. Match the terminals shown on the label with those on theDX. Terminal locations on the label are the same as
physical terminal locations.
The diagram below illustrates how to match DX-PD2C5terminals with those on the label.

2. View the channel name above each pair of terminals onthe label. A channel name comprises the terminal typeand a channel number, such as CC1, PDC1, DC1, and thelike.

Step 2: Connect Detectors or Actuators to Terminals (onpage 1)
Step 3: Connect DX to a Raritan PDU or EMX (on page 2)
QS RuleStep 1: Identify Terminals
If your DX has only one pair of terminals, such as DX-PIR, theterminals are a contact closure sensor channel unless the DXsensor name contains "Dn" or "PDn" , where n is a number.
If your DX has more than one pair of terminals, such as
DX-D2C6 or DX-PD2C5, a terminal label indicating allterminal locations and types is affixed to the DX. A terminallabel looks like the following DX-PD2C5 label.

Contact closure sensor channels

PDC

Powered dry contact channels

DCDry contact channels

QS RuleStep 2: Connect Detectors or Actuators toTerminals
A CC channel connects a contact closure sensor. A DC or
PDC channel connects an actuator, which controls a system.
Warning: DX sensor packages do NOT support all types ofcontact closure sensors or actuators. For example, DX
does not support Raritan's DPX water sensors. See theEnvironmental Sensors Guide for restrictions.

To connect a detector or actuator to a pair of terminals:
1. Strip the insulation around 12mm from the end of eachwire of a detector or actuator.
 Wire size range: AWG 28 to 20 or 0.09 to 0.5 square
millimeters
2. Fully insert each wire into each termination point of a CC,DC or PDC channel on the DX sensor package.
Important: For a PDC channel, you must check theelectrical polarity markings (+ and -) on the DX label tomake sure each wire is inserted into the correct
termination point with the correct polarity.

Warning: Do NOT use a crossover cable to connect DX.
QS RuleDip Switches and LEDs
Dip switches and LED indicators are associated with CCchannels, and their sequence matches the CC channelsequence. The following diagram illustrates how the CC
channel sequence on DX-PD2C5 matches the sequence of
dip switches (in blue) and LED indicators (in red).

Dip switches:
3. Use a screwdriver with a 2.5 mm wide shaft to tighten thescrews above each termination point to secure the wires,using a torque of 0.196 N·m (2 kgf·cm).
4. Repeat the above steps if your DX has more terminals.

Dip switches determine the normal settings of associated CCchannels.
On (down): Set to "Normally Open"Off (up): Set to "Normally Closed"

QS RuleLED indicators:

Step 3: Connect DX to a Raritan PDU or EMX
An appropriate cable is required for connecting DX to aRaritan product like a PDU or EMX. The appropriate cablevaries based on the sensor port type of the Raritan product.
Warning: NOT all Raritan products support all DX sensor
packages. See the Environmental Sensors Guide forrestrictions.
RJ-12 sensor port, such as PX2, EMX and PXE:
Use the RJ-12 to RJ-45 adapter cable shipped with the DX
sensor package. Connect the cable's RJ-12 connector to thesensor port of your Raritan PDU or EMX, and the RJ-45connector to either RJ-45 port of the DX.
The adapter cable's part number: 254-01-0032-00
RJ-45 sensor port, such as PX3 and PX3TS:

An LED indicator indicates the state of the associated CC
channel if a contact closure sensor has been connected.
Solid On: Alarmed state
Off: Normal state
CC1 LED flashing: Sensor firmware upgrade in process

QS RuleCascading
Most DX sensor packages support cascading using standard
network patch cables but some may not support it, such asDX-PD2C5. See the Environmental Sensors Guide forrestrictions.
Supported maximum total cable length:
DX supports a distance up to 98 feet (30 m) except for
DX-PD2C5, which supports only up to 29 feet (9 m).

Use a standard network patch cable with RJ-45 connectors on
both ends. Connect one end to the sensor port of your Raritan
PDU, and the other end to either RJ-45 port of the DX.
