WRS-SST Series Wireless Sensing System Tools Overview

The WRS-SST Series Wireless Sensing System Tools are optional, lightweight, portable, battery-powered, wireless receivers designed to receive wireless data transmissions from WRS-TTx Series Sensors, TE-7800 Series Receivers, and WRS-RTN Series Receivers in One-to-One and Many-to-One sensing system applications (Figure 1).

When connected to a properly configured laptop computer, the sensing system tool receives wireless data transmissions from specified sensors or receivers, and display Radio Frequency (RF) signal strength data, zone temperature and occupancy data, and wireless device information in the tool’s User Interface (UI) in a HyperTerminal window on the laptop screen.

The WRS-SST Series Sensing System Tool features multiple modes of operation to serve two primary purposes:

• testing the RF signal strength between sensing system device locations, which helps to determine the optimum locations for sensors and receivers in wireless room temperature sensing system applications prior to system installation

• providing information about operating sensing system applications, which helps to troubleshoot existing wireless room temperature sensing system applications after installation

Note: The WRS Series Many-to-One Wireless Room Temperature Sensing System supports two methods of Internet Protocol (IP) address assignments: static and Dynamic Host Configuration Protocol (DHCP). To use the WRS-SST Series Tool in the Many-to-One monitor mode (only) to monitor an existing WRS-RTN Series Receiver configured for dynamic IP addressing, the receiver must be date coded 0734 or later. All other WRS-SST Series Tool modes do not require a special date-coded WRS-RTN Series Receiver.

You can configure the tool and laptop computer to collect wireless sensing system information and save it to a text file on the laptop. The text files can be printed from the laptop. You can also use the tool to collect RF signal strength and temperature trend data from zones in your sensing system applications.

WRS-SST Series Tools Modes of Operation

The sensing system tool has five modes of operation: Stand-Alone mode, One-to-One receiver mode, Many-to-One receiver mode, One-to-One monitor mode, and Many-to-One monitor mode.

In Stand-Alone mode, the sensing system tool is not connected to a laptop computer. When the tool is connected to a laptop computer, you can select from the remaining four modes of operation that are enabled on the Main menu in the tool’s UI on the laptop screen. The mode selected determines the type of sensing system that the tool monitors and the information fields displayed on the laptop screen.

Stand-Alone Mode

In Stand-Alone mode, the sensing system tool is not connected to a laptop computer, and the tool operates like a portable, battery-powered receiver. The sensing system tool associates with and receives data transmissions from a single WRS-TTx Series Sensor that is configured as a test sensor. In Stand-Alone mode, the RF signal strength between the sensor and tool is indicated by a series of flashes or blinks on the sensor and tool Light-Emitting Diodes (LEDs). See Rapid Transmit Mode and RF Signal Strength LEDs on page 12 more information on LED RF signal strength indication.

Typically, you use the Stand-Alone mode to quickly test the RF signal strength between the intended receiver and sensor locations prior to installing a One-to-One or Many-to-One sensing system. See Using the WRS-SST Series Tool in Stand-Alone Mode on page 20 for detailed procedures.

One-to-One Receiver Mode

In One-to-One receiver mode, the sensing system tool receives data transmissions from one to four sensors in a One-to-One sensing system application and displays system information on the laptop screen (Figure 3). See Information Displayed in the Receiver Modes on page 8.

Typically, you use One-to-One receiver mode to troubleshoot an existing One-to-One sensing system. You can also use the sensing system tool in One-to-One receiver mode to determine the optimum locations for mounting a TE-7800-x Series Receiver and up to four associated WRS-TTx Series Sensors prior to installing a One-to-One sensing system application. See Using the WRS-SST Series Tool in One-to-One Receiver Mode on page 21 for detailed procedures.

Many-to-One Receiver Mode

In Many-to-One receiver mode, the sensing system tool associates with and receives data transmissions from one to eight selected WRS-TTx Series Sensors in a Many-to-One sensing system application and displays system information on the laptop screen. See Information Displayed in the Receiver Modes on page 8.

Typically, you use Many-to-One receiver mode to troubleshoot an existing Many-to-One sensing system. You can also use the sensing system tool in Many-to-One receiver mode to determine the optimum locations for mounting a WRS-RTN Series Receiver and up to eight associated WRS-TTx Series Sensors prior to installing a Many-to-One sensing system application. See Using the WRS-SST Series Tool in Many-to-One Receiver Mode on page 22 for detailed procedures.

One-to-One Monitor Mode

In One-to-One monitor mode, the sensing system tool monitors the data transmissions sent from a single TE-7800 Series Receiver to the associated sensors in a One-to-One sensing system and displays system information on the laptop screen. See Information Displayed in the Monitor Modes on page 10.

Typically, you use One-to-One monitor mode to troubleshoot an existing One-to-One sensing system. One-to-One monitor mode is especially useful in troubleshooting One-to-One applications where the TE-7800 Series Receiver is not easily accessible. See Using the WRS-SST Series Tool in One-to-One Monitor Mode on page 24 for detailed procedures.

Many-to-One Monitor Mode

In Many-to-One monitor mode, the sensing system tool monitors the data transmissions from a WRS-RTN Series Receiver to the associated sensors in a Many-to-One sensing system and displays system information on the laptop screen (Figure 4). See Information Displayed in the Monitor Modes on page 10.

To enable the sensing system tool to monitor a WRS-RTN Series Receiver, you enter the receiver’s IP address in the tool UI. The sensing system tool monitors all data transmissions sent by the receiver and can provide information about each sensor associated with the monitored receiver. See Using the WRS-SST Series Tool in Many-to-One Monitor Mode on page 25 for detailed procedures.

Note: To use the WRS-SST Series Tool in the Many-to-One monitor mode (only) to monitor an existing WRS-RTN Series Receiver configured for dynamic IP addressing, the receiver must be date coded 0734 or later. All other WRS-SST Series Tool modes do not require a special date-coded WRS-RTN Series Receiver.

Note: Metasys® system Release 3.1 or later software is required to employ dynamic IP addressing on the WRS-RTN Series Receiver.

Information Provided by the WRS-SST Series Tool

Data transmissions from sensors and receivers in One-to-One and Many-to-One sensing systems contain RF signal strength information, zone occupancy status, zone temperature and setpoint status, sensor identification information, sensing system device status, and sensor battery status. When a data transmission is received by the sensing system tool, some of this information is displayed in a line of text in a HyperTerminal window on the laptop screen. The information displayed on the laptop screen depends on the mode of operation that the sensing system tool is in.

Information Displayed in the Receiver Modes

In the receiver modes, the sensing system tool associates with and receives data transmissions from selected WRS-TTx Series Sensors. In a receiver mode, values for the following information fields are displayed, on a line of text in the tool’s UI, for each sensor transmission received by the tool (Figure 5).

Tool Clock Time

The displayed time is the time in hours, minutes, and seconds according to the sensing system tool’s 24-hour time clock (for example, 13:00:24). The sensing system tool’s clock is set in the tool UI on the laptop computer. The clock time is reset to 00:00:00 every time the sensing system tool is turned off (or loses battery power). See Setting the WRS-SST Series Tool Clock on page 20 for more information.

Property Code and Transmitter ID Values

The UI displays the WRS-TTx Series Sensor Property Code and Transmitter ID values (sensor address) for the WRS-TTx Series Sensor generating the line of information (for example, Prop00 ID 257). These values are set on the sensor DIP switch blocks. One-to-One sensors do not use a Property Code value, and in One-to-One applications, the sensor Property Code value is always 00.

Figure 5: Typical Information Displayed in HyperTerminal Window on Laptop Screen When the WRS-SST Series Tool Is in a Receiver Mode


Serial Number

The UI displays the sensor’s unique serial number in hexidecimal characters (for example, Sn00001A). No two sensors have the same serial number.

Temperature Setpoint Value

The temperature setpoint value is displayed in the UI as a percentage of the sensor’s total adjustment range (for example, SetPt 070%).

The WRS-TTP0000-x and WRS-TTS0000-x Series models have a setpoint adjustment dial, and the displayed setpoint value is a percentage (0 to 100%) of the total setpoint adjustment range (depending on the dial position). When a sensor’s setpoint dial is adjusted, the setpoint value (percentage) changes, and the new value is displayed in the next line of text generated by a sensor transmission.

The WRS-TTR000-x Series models do not have an adjustment dial, and SetPt 100% is always displayed in this field.

Note: Actual zone temperature setpoints are configured in the target field controller, the Network Automation Engine (NAE) UI, or the Network Control Engine (NCE) UI. Refer to the TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT-12011097) or the WRS Series Many-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT-12011095) for information on sensor adjustments and setting zone temperature values.

Sensed Temperature Value

The UI displays the current temperature in °C and °F sensed at the sensor (for example, Tmp +24.17C +75.51F).

Battery Power Status

The UI displays the current status of the sensor’s battery power (for example, Bat OK or Bat Lo [low]).

Zone Occupancy Override

The UI displays whether or not the sensor transmission has initiated zone occupancy override (for example, Occ Y = data transmission has initiated a zone occupancy override or Occ N = data transmission has not initiated a zone occupancy override).

Note: Pressing the occupancy override button on a sensor generates a manual data transmission and initiates an occupancy override command. Manually generated transmissions always display OccY. The zone occupancy parameters are configured in a (compatible) target field controller, the NAE UI, or the NCE UI. Refer to the TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT-12011097) or the WRS Series Many-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT-12011095) for information on setting zone occupancy values.


Rapid Transmit Mode Status

The UI appears if the sensor is in Rapid Transmit Mode (RTM) or not (for example, RpXmt Y or RpXmt N). When a WRS-TTx Series Sensor is forced into RTM, it generates a data transmission every 10 seconds. Each sensor data transmission generated in RTM is displayed in the UI as long as the sensing system tool is associated with the sensor. See Rapid Transmit Mode and RF Signal Strength LEDs on page 12 for more information.

Transmission Count

The UI displays the number of the data transmissions generated by a sensor. For example, XCnt025 is the 25th transmission sent by the sensor. The sensor can count up to 255 transmission, then it rolls the counter over to XCnt001.

When powered on, a sensor automatically sends a transmission approximately every 60 seconds. The first transmission received by a receiver or sensing system tool establishes the sensor to receiver/tool association, and XCnt000 is displayed. After the association is established, the sensor counts each subsequent sensor transmission (even if the transmission is not received). A missing transmission count indicates that a sensor data transmission was not received by the associated tool (in the receiver modes) or the monitored receiver (in the monitor modes).

RF Signal Strength

RF signal strength indicates the strength of the RF signal between the sensor and the associated sensing system tool, expressed in dBm, followed by the RF signal strength expressed as Excellent, Good, or Weak, followed by the signal strength expressed as a percent of the typical signal strength range (where -90 to -65 dBm equals 0 to 100%). For example, SgStr -29dB,E,100% where -29dB = -29 dBm signal, E = Excellent, and 100% = 100 percent of the optimum signal strength.

RF Quality

The RF quality value range of 50 to 110 represents the RF signal strength relative to the ambient RF interference impact on the RF signal (for example, RFQual 107). Displayed RF quality values of 80 or greater are considered adequate or excellent. Lower values indicate ambient RF interference may be impacting the data transmissions between a sensor and the associated tool or receiver.

Note: On the Metasys UI, the RF quality value range is converted to 0 to 100, where values of 50 or greater are considered adequate or excellent.

Information Displayed in the Monitor Modes

In the monitor modes, the sensing system tool is configured to monitor and display data transmissions sent to WRS-TTx Series Sensors by either a TE-7800 Series Receiver in a One-to-One system or a WRS-RTN Series Receiver in a Many-to-One system.

The sensing system tool monitors two types of data transmissions in monitor mode: association grants and acknowledgements.


An association grant is the initial reply generated by a receiver and sent to an unassociated WRS-TTx Series Sensor in response to a data transmission from the sensor. An association grant enables the sensor to establish and maintain an association with the receiver. If the association is broken, another association grant must be generated to reestablish the association.

An acknowledgement is a routine reply generated by a receiver and sent to an associated WRS-TTx Series Sensor to confirm a sensor data transmission. After a receiver generates an association grant and establishes an association with the sensor, the receiver replies to all subsequent sensor transmissions with an acknowledgement (until the association is broken). The vast majority of the data transmissions sent by a receiver are acknowledgements.

In the monitor modes, the sensing system tool monitors all of the association grants and acknowledgements sent by a single sensing system receiver to all of the WRS-TTx Series Sensors associated with that receiver. System information from the monitored transmission is displayed in the tool UI (Figure 6).

In the monitor modes, the sensing system tool UI displays many of the same fields displayed in the receiver modes. See Tool Clock Time, Property Code and Transmitter ID Values, Serial Number, Transmission Count, RF Signal Strength, and RF Quality in the Information Displayed in the Receiver Modes section for information on fields that are also displayed in the receiver modes and monitor modes. In the monitor modes, the following fields are also displayed.

Data Transmission Type

The UI displays the type of data transmission generated by the receiver, either an association grant (AssocGrnt) or an acknowledgement (SenAcknwl).

Frequency

The UI displays the Zigbee™ channel (number) on which the sensor data transmission was sent (for example, Freq20).

Figure 6: Typical Information Displayed in HyperTerminal Window on Laptop Screen When the WRS-SST Series Tool Is in a Monitor Mode


Sensor Transmission Power

Sensor transmission power is a fixed value (for example, Spwr32). On WRS-TTx0000-0 Series Sensor models for the North American market, the radio transmitters are configured to transmit at the maximum power (32) which corresponds to 15 dBm; therefore, in North American applications, the sensor transmission power value should always be Spwr32. WRS-TTx0000-1 Series reduced transmission power (10 dBm) CE Mark compliant models are configured to transmit at the maximum power (10).

Receiver Transmission Power

Receiver transmission power is a fixed value (for example, Rpwr32). On TE-78x0-0 Series Receivers and the WRS-RTN0000-0 Receiver for the North American market, the radio transmitters are configured to transmit at the maximum power (32) which corresponds to 15 dBm; therefore, in North American sensing system applications, the receiver transmission power value should always be Rpwr32. TE78x0-1 Series and the WRS-RTN0000-1 reduced transmission power (10 dBm) CE Mark compliant models are configured to transmit at the maximum power (10).

RF Signal Strength

In the monitor modes, RF signal strength indicates the signal strength between a WRS-TTx Series Sensor and the associated receiver. See RF Signal Strength in the Information Displayed in the Receiver Modes section for more information on the RF signal strength value.

WRS-SST Series Tool Help

The sensing system tool can display Help pages in the UI. The Help pages have abbreviated information on the fields and values displayed in the UI and on how to set up the tool in each of the four modes of operation available when the tool is connected to a laptop computer. Select 6 in the tool’s Main menu to go to the tool Help pages. See Connecting a Laptop Computer to the WRS-SST Series Tool and Accessing the Tool UI on page 18 for procedures on accessing the Help pages.

Rapid Transmit Mode and RF Signal Strength LEDs

Pressing and holding the manual occupancy override button on a WRS-TTx Series Sensor for 3 seconds or more forces the sensor into RTM. In RTM, a WRS-TTx Series Sensor sends a data transmission once every 10 seconds. Many-to-One sensors remain in RTM for up to 100 seconds. One-to-One sensors remain in RTM for up to 30 minutes. After each RTM transmission, the sensor occupancy LED flashes on one, two, or three times every 10 seconds to indicate the RF signal strength between the sensor and the receiver or sensing system tool.

In the receiver modes, the RF SIGNAL LED on the sensing system tool blinks off one, two, or three times every 10 seconds to indicate the signal strength between the sensor and tool. In the monitor modes, the RF SIGNAL LED on a TE-7800 Series Receiver or the WIRELESS LED on a WRS-RTN Series Receiver blinks off one, two, or three times every 10 seconds to indicate the signal strength between the sensor and associated receiver.

• No flashes/blinks indicate no RF signal.

• One flash/blink indicates a weak RF signal.


• Two flashes/blinks indicate a good RF signal.

• Three flashes/blinks indicate an excellent RF signal.

Press (and quickly release) the manual occupancy override button on a WRS-TTx Series Sensor to terminate RTM and reset the sensor to normal operation.

Setting the WRS-SST Series Tool Clock

To set the clock on the sensing system tool:

1. With the tool’s Main menu displayed, press 5 on the laptop keyboard to display the field for setting the tool time clock (Figure 17).

2. Enter the desired time setting in 24-hour format (HH:MM:SS).

3. Press Enter to set the time and start the clock at the desired time setting and return to the Main menu.

Note: The time clock returns to the default starting value whenever the sensing system tool is turned off or loses power.

If you do not set the sensing system tool time clock, the timer and time field display the time that has elapsed in the session (up to 24 hours) since the tool was powered on.

Using the WRS-SST Series Tool in Stand-Alone Mode

Use the sensing system tool in Stand-Alone mode (without a laptop computer) to test the RF signal strength between a single WRS-TTx Series Sensor and the tool. See Stand-Alone Mode on page 5 for more information. Typically, Stand-Alone mode is used to quickly test the signal strength between (potential) sensor and receiver locations prior to installing the sensors and receivers to determine the optimum locations for the devices in One-to-One or Many-to-One sensing system applications.

To test RF signal strength with sensing system tool in Stand-Alone mode:

1. Mark (or otherwise indicate) the intended locations of the receiver and all of the sensors associated with the receiver.

2. Set all of the PROPERTY CODE DIP switches on the test sensor to the OFF position.

3. Set the TRANSMITTER ID DIP switches on the test sensor to the same positions as the RF ADDRESS DIP switches on the tool so that the sensor address is the same value as the tool RF address.

Figure 17: Setting the WRS-SST Series Tool Clock


Note: Ensure that no other sensing system receivers or sensors with the same address are powered and nearby. Active sensing system devices with the same address as the sensing system tool and test sensor can interfere with RF signal strength testing.

The RF address value of 510 should be reserved for testing One-to-One sensing system applications. You can use an address value of 510 for the test sensor and sensing system tool to avoid interference from other One-to-One devices.

4. Position the tool at a location where you intend to mount the sensing system receiver, position the tool’s antenna in a vertical position (pointing up or down), and power the tool on.

Note: For the most accurate test results, locate the tool and position the tool antenna exactly as the receiver and receiver antenna would be located and positioned.

5. Power on the test sensor and press the occupancy override button for 3 seconds to force the test sensor into RTM.

6. Hold the test sensor upright and as close as possible to an intended sensor location for at least 10 seconds. The occupancy override LED should emit one to three rapid flashes, which indicates the RF signal strength between the test sensor and the tool. (See Rapid Transmit Mode and RF Signal Strength LEDs on page 12 for more information on RTM and RF signal strength indication.)

7. Hold the sensor in place for another 10 seconds to verify the test and record the results for the sensor location.

8. Move the test sensor to the next intended sensor location and repeat Steps 6 and 7.

9. Repeat Step 8 for each of the associated sensor locations.

10. If you have more receiver locations to test, move the sensing system tool and repeat Step 1 and Steps 4 through 9 for each receiver location.

Using the WRS-SST Series Tool in One-to-One Receiver Mode

In One-to-One receiver mode, the sensing system tool receives data transmissions from up to four WRS-TTx Series Sensors in a One-to-One application. Typically, you use the sensing system tool in One-to-One receiver mode to troubleshoot an existing One-to-One sensing system application. You can also use the sensing system tool in One-to-One receiver mode to determine the optimum locations for mounting a TE-7800 Series Receiver and up to four associated WRS-TTx Series Sensors prior to installing a One-to-One sensing system application. See One-to-One Receiver Mode on page 6 for more information.


Before you use the tool in One-to-One receiver mode, you should:

• ensure that the sensor or sensors you are testing are turned on, and that they all have the same sensor address and that the address is a valid One-to-One sensor address (no Property Code value)

• ensure that the sensing system tool RF address is the same value as the sensor or sensors you are testing

• ensure that the TE-7800 Series Receiver (associated to the sensor or sensors you are testing) is turned off

See Connecting a Laptop Computer to the WRS-SST Series Tool and Accessing the Tool UI on page 18 and Setting the WRS-SST Series Tool Clock on page 20 for more information.

To use the sensing system tool in One-to-One receiver mode:

1. Position the sensing system tool next to (or in place of) the TE-7800 Series Receiver that is associated to the sensor or sensors you are testing.

2. Ensure the Main Menu is the active menu in the tool UI and then press 1 to place the tool in One-to-One receiver mode.

3. Wait for at least 1 minute. Each target sensor should associate with the tool and begin sending data transmissions to the tool approximately once every minute.

You can force any or all of the sensors you are testing into RTM to generate sensor transmission every 10 seconds. See Rapid Transmit Mode and RF Signal Strength LEDs on page 12 for more information.

You can collect information for as long as the sensing system tool batteries last, but the HyperTerminal window displays only the 24 most recent lines of text generated by the tool.

You can save the collected information to a file on the laptop computer and display the data in a text editor (such as Notepad) or word processing application or print the collected information to a printer connected to the laptop.

Use the information to troubleshoot your One-to-One application. See Information Displayed in the Receiver Modes on page 8 for more information.

Using the WRS-SST Series Tool in Many-to-One Receiver Mode

In Many-to-One receiver mode, the sensing system tool receives data transmissions from up to eight WRS-TTx Series Sensors in a Many-to-One application. Typically, you use the sensing system tool in Many-to-One receiver mode to troubleshoot an existing Many-to-One sensing system application. You can also use the sensing system tool in Many-to-One receiver mode to determine the optimum locations for mounting a WRS-RTN Series Receiver and up to eight associated WRS-TTx Series Sensors prior to installing a Many-to-One sensing system application. See Many-to-One Receiver Mode on page 6 for more information.

Using the WRS-SST Series Tool in One-to-One Monitor Mode

In One-to-One monitor mode, the sensing system tool monitors the data transmissions from a TE-7800 Series Receiver that are sent to (up to four) associated WRS-TTx Series Sensors. Typically, you use the tool in One-to-One monitor mode to troubleshoot existing One-to-One sensing system applications. The One-to-One monitor mode is especially useful in troubleshooting One-to-One applications where the receiver is not easily accessible. See One-to-One Monitor Mode on page 6 for more information.

Before you use the tool in One-to-One monitor mode, you should:

• ensure that the sensor or sensors you are testing are turned on, and that they all have the same sensor address and that the address is a valid One-to-One sensor address (no Property Code value)

• ensure that the RF address value (RF ADDRESS DIP switch positions) on the TE-7800 Series Receiver match the sensor address value (TRANSMTTER ID DIP switch positions) of the sensor or sensors you are testing

• ensure that the TE-7800 Series Receiver is turned on

• ensure that the sensing system tool RF address value (RF ADDRESS DIP switch positions) matches the receiver you are monitoring

• ensure that no other active receivers or sensors with the same RF address value as the sensing system tool and receiver you are monitoring are near your test site


To use the sensing system tool in One-to-One monitor mode:

1. Position the tool in a direct line-of-sight path with the target TE-7800 Series Receiver.

Note: For the WRS-SST-100 model, do not exceed the practical indoor limit of 200 ft (61 m). For the WRS-SST-101 model, do not exceed the practical indoor limit of 165 ft (50 m). For either model, do not place the tool less than 3 ft (1 m) from the target receiver.

2. Ensure the Main Menu is the active menu in the tool UI and then press 3 to place the tool in One-to-One monitor mode. The tool attempts to sync up with the receiver. (This may take up to 30 seconds.) Then Synchronization achieved is displayed in the tool UI and the receiver messages are displayed in the UI as they are sent by the receiver.





Use the information to troubleshoot your One-to-One application. See Information Displayed in the Monitor Modes on page 10 for more information.

Using the WRS-SST Series Tool in Many-to-One Monitor Mode

In Many-to-One monitor mode, the sensing system tool monitors all of the data transmissions from a WRS-RTN Series Receiver that are sent to the associated WRS-TTx Series Sensors in a Many-to-One application. Typically, you use the tool in Many-to-One monitor mode to troubleshoot existing Many-to-One sensing system applications. The Many-to-One monitor mode is especially useful in troubleshooting Many-to-One applications where the receiver is not easily accessible. See Many-to-One Monitor Mode on page 7 for more information.

Note: Up to 60 WRS-TTx Series Sensors can be associated to an WRS-RTN Series Receiver, but the practical average is 10 to 20 sensors per receiver.


Before you use the tool in Many-to-One monitor mode:

• ensure that the sensors in the Many-to-One application (you are testing) are turned on, and that they have a valid Many-to-One sensor address

• ensure that there are no other active Many-to-One sensors (near your test site) with any of the same sensor addresses as the sensors you are monitoring

• ensure that the WRS-RTN Series Receiver you are monitoring is configured with a valid static or dynamic IP address, and is turned on

• ensure that the sensors in the Many-to-One application are mapped to the WRS-RTN Series Receiver of the Wireless Supervisor on the NAE UI or NCE UI. Refer to the WRS Series Many-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT-12011095) for information on mapping sensors to WRS-RTN Series Receivers.

• ensure that there are no other active WRS-RTN Series Receivers (near your test site) with the same IP address as the receiver you are monitoring


To use the sensing system tool in Many-to-One monitor mode:

1. Position the tool in a direct line-of-sight path with the target WRS-RTN Series Receiver.

Note: For the WRS-SST-100 model, do not exceed the practical indoor limit of 200 ft (61 m). For the WRS-SST-101 model, do not exceed the practical indoor limit of 165 ft (50 m). For either model, do not place the tool less than 3 ft (1 m) from the target receiver.

2. Ensure the Main Menu is the active menu in the tool UI and then press 4 to place the tool in Many-to-One monitor mode

3. Type the target WRS-RTN Series Receiver’s IP address and press Enter. If the receiver is configured with a static IP address, obtain the address from the IP address sticker on the front of the receiver. If the receiver is configured for dynamic IP addressing, obtain the address from the Advanced focus view of the Wireless Receiver object on the NAE or NCE. The tool attempts to sync up with the receiver. (This may take up to 30 seconds.) Then Synchronization achieved is displayed in the tool UI, and the receiver messages are displayed in the UI as they are sent by the receiver.

Note: To use the WRS-SST Series Tool in the Many-to-One monitor mode (only) to monitor an existing WRS-RTN Series Receiver configured for dynamic IP addressing, the receiver must be date coded 0734 or later. All other WRS-SST Series Tool modes do not require a special date-coded WRS-RTN Series Receiver.

Note: Metasys system Release 3.1 or later software is required to employ dynamic IP addressing on the WRS-RTN Series Receiver.


If the Many-to-One monitor mode of the WRS-SST Series Wireless Sensing System Tool does not function for a temperature sensing system configured for dynamic IP addressing, cycle the power on the receiver. Next, go to the Advanced focus view of the Wireless Receiver object on the NAE or NCE to obtain the IP address of the receiver, since it may have changed when the power was cycled on. Enter this receiver IP address into the WRS-SST Series Wireless Sensing System Tool.
