Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 7 Introducing SNS™ Temperature and Humidity Sensors SNS™ Temperature and Humidity Sensors provide monitoring and logging of environmental conditions throughout your facilities. SNS Temperature and Humidity Sensors (sensor devices) communicate with the Synchronized Network Solutions (SNS) Application Management Platform (AMP)/Network Time Protocol (NTP) server over wireless 802.11 b/g networks. (Some sensor devices can also communicate over the wired Ethernet network.) Figure 1 shows the architecture of an SNS Temperature and Humidity Sensors network. Figure 1: SNS Temperature and Humidity Sensors Network Sensor Devices and Accessories Primex Wireless offers battery- and AC-powered sensor devices and probes. An important accessory for both AC- and battery powered external probe sensors is the SNS thermobuffer, which enables sensor readings to be based on the temperature of the refrigerated assets rather than on the air temperature. AC-powered Sensor Devices and Accessories Table 1 and Table 2 describe the AC-powered sensor devices and accessories. For more on AC-powered sensor devices, see Features of SNS AC-powered Sensor Devices on page 12.

Introducing SNS™ Temperature and Humidity Sensors Overview of SNS Sensor Network Installation Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 9 SNS Thermobuffers A thermobuffer can be used with battery- and AC-powered single and dual probe temperature sensors to simulate the actual temperature of contents within coolers or freezers. The thermobuffer is a bottle of food-grade glycol into which the temperature probe is placed inside the refrigerator. The thermobuffer simulates refrigerated items, which change temperature more slowly than the air when the refrigerator door is opened. Using a thermobuffer with sensor devices limits the impact of fluctuating air temperature on sensor readings and helps provide a higher degree of measurement accuracy. The thermobuffer is effective to a minimum temperature of -27° F. Table 5: SNS Thermobuffer Accessories Accessory Part Number Accessory Description SNSGRP SNS Thermobuffer, 4 oz. Glycol Bottle for RTD Probe and Thermistor (NIST) SNSGLY-1 1 Gallon Food Grade Glycol Overview of SNS Sensor Network Installation Prerequisites to SNS Sensor Installation The following tasks must be complete before installing SNS Sensors. • Install and set up the SNS Application Management Platform (AMP)/Network Time Protocol (NTP) server. • Enter the SNS Sensors license key in the AMP. • Assign the Sensor Admin role to the AMP administrator or other user login. This installation guide assumes that the AMP and Sensors license are installed and that you can log in to the AMP as a user with the Sensor Admin role. See the SNS AMP Installation and Administration Guide and the SNS Temperature and Humidity Sensors User Guide for details. Plan the Installation Sensor device installation begins by planning where to place sensor devices and ensuring that the wireless or wired network is available at these locations. Note: Sensor devices must have adequate signal to support wireless operation. Sensor devices will work in areas where a wireless laptop can connect to the network or where signal to noise level measures 20 dB or greater. If wireless signal is inadequate, a wireless Access Point may be added in proximity to improve local signal strength. AC-powered sensor devices can also be connected to the Ethernet network via the RJ45 connector. Configure Sensor Devices for the Network Sensor devices arrive at your facility with no knowledge of the network. The next step in installing the SNS Sensors network is to configure sensor devices. See Configure Sensors for the Network on page 25 for details. Install and Verify Sensor Devices Once sensors are configured and you know they can connect to the network, they are ready for installation in their permanent locations. See Install SNS Sensor Devices and Accessories on page 47 for details.

You will also use AMP pages to enter information, such as the location of the sensor device or alerting thresholds. See the SNS Temperature and Humidity Sensors User Guide for details.
Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 11 Network Requirements for SNS Sensor Devices SNS Temperature and Humidity Sensors work on 802.11 b/g wireless networks. Some sensors also work on wired Ethernet networks. This section describes the requirements for the SNS Temperature and Humidity Sensors network. Wireless Signal Sensor devices must have adequate signal to support wireless operation. Sensor devices will work in areas where a wireless laptop can connect to the network or where signal to noise level measures 20 dB or greater. If wireless signal is inadequate, a wireless Access Point may be added in proximity to improve local signal strength. AC-powered sensor devices can also be connected to the Ethernet network via the RJ45 connector. Wireless Security AC-powered Sensor Devices AC-powered sensor devices support WEP, WPA, and WPA2 encryption standards with LEAP, EAP-FAST, and PEAP authentication. Battery-powered Sensor Devices Battery-powered sensor devices support WEP - 128, WPA-TKIP, and WPA2-AES encryption standards. Network Protocol and Ports AC-powered Sensor Devices AC-powered sensors send sensor device data via UDP packets. Ports 1600 and 1640 must be open on the network for data transmission and configuration. Battery-powered Sensor Devices Battery-powered sensors send sensor device data via UDP packets.

Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 12 Features of SNS AC-powered Sensor Devices This section contains the following topics: • Network, Power, and Probe Connections • Service Button • Visual and Auditory Interfaces • Monitoring Thresholds • Operational Sequences Network, Power, and Probe Connections Network, power, and probe connections are located on the side of AC-powered sensors, as shown in Figure 2. Dual-probe sensor devices contain two probe jacks. Figure 2: Network, Power, and Probe Connections on AC-Powered Temperature Sensor (SNSATPD) Network Connection The RJ-45 network connection allows you to connect a standard Ethernet cable to the sensor device. The network connection is used during browser-based configuration and if the sensor device is configured to operate on the wired Ethernet network. For details on configuration, see Configure Sensors for the Network on page 25. AC-Power Connection AC-powered sensor devices come with a power supply. Plugging in the power supply and connecting it to the sensor device turns on the sensor device. AC-powered sensor devices must be connected to AC power for normal operation. Probe Connection(s) AC-powered temperature sensor devices have one or two probe connections depending on the sensor device model. Service Button The service button is located on the front of AC-powered sensor devices, as shown in Figure 3.
Features of SNS AC-powered Sensor Devices Visual and Auditory Interfaces Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 13 Figure 3: Service Button, Display, and LED on AC-Powered Temperature Sensor (SNSATPD) The service button has several uses depending on the status of the sensor device. • To enable browser-based configuration, pressing and holding the service button while plugging in the sensor device causes the device to enter configuration mode. • During normal operation and discovery and auto-configuration, pushing the service button causes the sensor device to sound the beeper and check in with the AMP. • During an alarm, pushing the service button cancels the alarm and stops the LED from flashing but does not acknowledge the alarm on the AMP. Pushing the service button during an alarm also does not sound the beeper or cause the sensor device to check in with the AMP. Visual and Auditory Interfaces The display and LED, shown in Figure 3, are visual indicators of sensor device status and sensor readings. The sensor device also communicates its status using beeps. Display Table 6 describes the display functions for AC-powered sensor devices. Table 6: AC-powered Sensor Device Display Item Description 38.1° F 65%RH Current reading of probe. For dual probe sensors, the reading alternates between showing the reading of probe 1 and probe 2 every three seconds. Numbers ‘1’ and ‘2’ in the upper left corner of the display indicate which reading is displayed. Before the display changes to show the other probe’s temperature, both probe inputs are sampled. MIN °F 32.0 Latest min and max temperature values. The min and max temperatures on the display are checked every time a new sample is taken. The min and max on the display are a daily min and max and every 24 hours from power up the daily min and max will be cleared and replaced by the first sample of the next 24 hour period. MAX °F 40.0
Features of SNS AC-powered Sensor Devices Visual and Auditory Interfaces Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 14 Item Description MIN %RH 75.0 Latest min and max relative humidity values. The min and max relative humidity on the display are checked every time a new sample is taken. The min and max on the display are a daily min and max and every 24 hours from power up the daily min and max will be cleared and replaced by the first sample of the next 24 hour period. Temperature and Humidity sensors only. MAX %RH 60.0 dIS One of the probes is disconnected from the device. If the probe was never plugged in since power up, no min or max will be shown until a probe is connected, though the device will continue to check in with the AMP at its normal interval. Temperature sensors only. LO Temperature below -40 °C. No temperature sample is taken or stored, though the device will continue to check in with the AMP at its normal interval. If the temperature drops much further below -40 °C the display will change from LO to SHr. Temperature sensors only. HI Temperature above 90 °C. Temperature sensors only. SHr One of the probe inputs is shorted. No temperature sample is taken or stored, though the device will continue to check in with the AMP at its normal interval. If the probe input was short since power up, no min or max will be displayed until the short is removed. Temperature sensors only. CON Device is in configuration mode. LO AC (Appears instead of MIN/MAX or %RH) Device is running on backup power. When running on backup power, the device slows its display rate and probe sampling rate down from every three seconds to every 15 seconds to conserve power. To save power, the radio, LED, and buzzer are never turned on in this mode. LED The LED has several meanings depending on the status of the sensor device. • When an alarm is active, the LED on AC-powered sensors flashes once per second. Pushing the service button when the LED is flashing stops the flashing but does not acknowledge the alarm on the AMP. • When in Find mode, the LED flashes rapidly 3 times per second. For information on Find mode, see the SNS Temperature and Humidity Sensors User Guide. • When powered up, the LED illuminates briefly. Beeps When the service button is pushed during normal operation, the sensor device emits two beeps and activates the radio to contact the AMP. Once a successful exchange with the AMP occurs, the device sounds the following series of beeps: • 1 beep indicates that the radio booted. • 2 beeps indicate that the sensor device has connected to network. • 3 beeps indicate that the sensor device has connected to the AMP. Connecting to the AMP usually takes about 25 seconds assuming a standard wireless connection with WPA2 security.
Features of SNS AC-powered Sensor Devices Monitoring Thresholds Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 15 Buzzer AC-powered sensor devices are equipped with an alarm buzzer. When an alarm is active, the buzzer sounds continuously, if Enable Audio Alerts is enabled (checked) on the sensor device’s Edit Sensor Device page in the AMP. Pushing the service button when the buzzer is sounding silences the buzzer but does not acknowledge the alarm on the AMP. Monitoring Thresholds AC-powered sensor devices permit you to set temperature and humidity monitoring thresholds. If the thresholds are exceeded or, depending on the configuration, exceeded for a period of time, the sensor device enters an alarm state. To set monitoring thresholds and download them to the sensor device, you edit sensor device information on the AMP. See the SNS Temperature and Humidity Sensors User Guide for information on editing AC-powered sensor devices, including monitoring thresholds. Operational Sequences Turn on the Sensor Device Plugging in an AC-powered sensor turns the device on. When the device is first powered up, it will turn on all of the LCD digits and the red LED. After 1 second, the display will briefly blank out and the LED will be turned off. The device will then read all of its configuration data out of non-volatile memory. If the device has never checked into an AMP, the default settings will be used. The default settings are: • Check-in Interval: 1 hour • Temperature Display: Fahrenheit • Alarms: None After the configuration data is loaded, both probes inputs are sampled and the display begins showing the temperature. The device then turns on its radio and proceeds to communicate with the AMP. Normal Operation Single probe temperature sensor devices update the probe reading every three seconds. Dual probe temperature sensor devices alternate between showing the temperature of probe 1 and probe 2 every three seconds, while temperature and humidity sensor devices alternate between showing temperature and humidity every three seconds. Before the display changes to show the other reading, both inputs are sampled. The min and max temperatures on the display are checked every time a new temperature sample is taken. The min and max on the display are a daily min and max and every 24 hours from power up the daily min and max will be cleared and replaced by the first sample of the next 24 hour period. Check-in with the AMP The sensor device checks in with the AMP at regular intervals (default 1 hour), starting when the device is powered up. If a check in with the AMP fails, the information is stored in non-volatile memory. The non-volatile memory is capable of storing 2046 readings. If the number of failed check-ins exceeds the size of the non-volatile memory, the oldest readings are overwritten. Any data stored in non-volatile memory will be lost if the device loses both AC and backup power.
Features of SNS AC-powered Sensor Devices Operational Sequences Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 16 Pushing the service button during normal operation forces the sensor device to check in with the AMP. When the service button is pressed, the sensor device will emit a series of beeps. The beeps signal the following connection sequence: 1= radio booted, 2 = connected to network, 3 = connected to the AMP (usually takes about 25 seconds to hear the beep assuming a standard wireless connection with WPA2 security). Configuration Mode Holding the button down while plugging the device in causes the device to enter configuration mode, regardless of whether it has been configured previously. While in configuration mode, you can perform browser-based configuration. When the device first enters configuration mode, it beeps once. This beep indicates to the user that they can take their finger off the button. While in configuration mode, the device flashes CON for one second and then goes blank for the next second. The sensor device continues to flash CON while in configuration mode. See Configure Sensors for the Network on page 25 for information on configuration. Handle Alarms When an alarm is active, the LED on the front of the sensor device flashes once per second and the buzzer sounds continuously, if Enable Audio Alerts is enabled (checked) on the sensor device’s Edit Sensor Device page in the AMP. If an alarm is active (LED is flashing), pushing the button cancels the alarm and stops the LED from flashing, but does not acknowledge the alarm on the AMP. Pushing the button during an alarm also does not sound the beeper or cause the sensor device to check in with the AMP. The behavior of the sensor device after cancelling an alarm depends on how the device is configured in the sensor device’s Edit Sensor Device page: • If a threshold has been exceeded with High Span Minutes blank and Audio Reset Period set at Indefinite, pushing the button cancels the alarm and an alarm will not occur again until the sensor goes back in range and then out of range again. • If a threshold has been exceeded with the Audio Reset Period is configured but High Span Minutes is blank, the alarm does not sound again until the Audio Reset Period expires. • If a Span Minutes has been exceeded, pushing the button cancels the alarm. If the device remains out of range and if an Audio Reset Period is configured, the alarm will not sound again until the Audio Reset Period expires. • If a Span Minutes has been exceeded, pushing the button cancels the alarm. If an Audio Reset Period is not configured, the alarm sounds again once Span Minutes runs out a second time. Backup Power AC-powered sensor devices have an internal super cap that allows the devices to continue to do many of their functions during an AC power outage. It normally takes about 8 hours to fully charge a super cap. Once fully charged, an AC-powered sensor device should be able to run on backup power for up to 4 hours. All data being collected by the probes is stored in non-volatile memory. This data will be lost if backup power fails. If AC power is restored before backup power fails and the temperature stayed within the set limits, all of the readings will be sent to the AMP as a single check in with the current temperature for the entire duration of the power outage. If a high or low limit is crossed while running on backup power, the data will be saved to non-volatile memory with a timestamp. This
Features of SNS AC-powered Sensor Devices Operational Sequences Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 17 data will be erased in the event that backup power fails. If it does not fail, these archived readings will be sent to the AMP as well as current temperature readings when AC power is restored so that you may see when temperatures went in and out of limits and for what duration. In the AMP Sensor Readings page, archived readings appear with a check mark in the Logged Readings column and have the same Transmit Count as the current reading.
Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 18 Features of SNS Battery-powered Sensor Devices This section contains the following topics: • On/Off Switch • Batteries • Programming Cable Connection • Probe Connections • Service Button • Visual and Auditory Interfaces • Monitoring Thresholds • Operational Sequences On/Off Switch Battery-powered sensor devices have on/off switches. The sensor devices must be turned on during configuration and normal operation. As shown in Figure 4, the on/off switch on model SNS2TNS-2 is located inside the sensor device. On this model, moving the switch away from the programming cable connection turns the sensor device on. On model SNS2TPS-2, the on/off switch is located in the battery compartment, as shown in Figure 5. On model, SNS2THS-2, it is on the side (Figure 6). Figure 4: Inside Model SNS2TNS-2
Features of SNS Battery-powered Sensor Devices Batteries Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 19 Figure 5: On/Off Switch Model SNS2TPS-2 Figure 6: Side of Model SNS2THS-2 Batteries SNS battery-powered sensors use two AA batteries located inside the sensor (Model SNS2TNS-2, Figure 4; Model SNS2TPH-2, Figure 12) or in an externally accessible battery compartment (Model SNS2TPS-2, Figure 5). Programming Cable Connection Battery-powered sensor devices come with a USB programming cable for use when configuring the sensor device. The standard USB connector connects to the computer that is running the configuration software utility. The other end of the programming cable connects to the sensor device’s programming connection. For information on configuring sensors, see Configure Sensors for the Network on page 25. As shown in Figure 4, Figure 6, and Figure 7, the location of the programming cable connection depends on the sensor model.

SNS™ Temperature and Humidity Sensors Installation Guide 20 Figure 7: Connections and Service Button on Model SNS2TPS-2 Probe Connections Single and dual external probe sensor devices contain probe jacks on the end of the sensor device, as shown in Figure 7. Service Button The service button is located on the side or end of the sensor device, depending on the model (See Figure 7 and Figure 9). As shown in Figure 8, on model SNS2TNS-2, the service button is inside the sensor device. On this model, the service button is activated by swiping the outside of the sensor device with the supplied magnet. Figure 8: Service Button on Model SNS2TNS-2 Figure 9: Service Button on Model SNS2THS-2
Features of SNS Battery-powered Sensor Devices Visual and Auditory Interfaces Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 21 The service button has several uses depending on the status of the sensor device. • Activating the service button causes the sensor device to check in with the AMP. • During an alarm, activating the service button cancels the alarm and stops the LED from flashing but does not acknowledge the alarm on the AMP. Activating the service button during an alarm also does not sound the beeper or cause the sensor device to check in with the AMP. Visual and Auditory Interfaces LEDs are visual indicators of sensor device status and sensor readings. The sensor device also communicates its status using beeps. LEDs Sensor devices have an LED visible from outside the sensor that indicates sensor status, as shown in Figure 10. Sensor devices also have an internal LED that may be useful for troubleshooting, as shown in Figure 4, Figure 11, and Figure 12. Figure 10: External Red LED Models SNS2TNS-2, SNS2TPS-2, and SNS2THS-2 Figure 11: Inside Model SNS2TPS-2
Features of SNS Battery-powered Sensor Devices Monitoring Thresholds Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 22 Figure 12: Inside Model SNS2THS-2 The red LED flashes to alert when the sensor device detects that a threshold that is programmed in the device has been exceeded. The red LED also indicates that a transmit attempt has just finished. The internal green LED indicates that the sensor device is connected to a network. When in sensor mode, the green LED will flash when a connection is made. When in setup mode (the programming cable is connected to the sensor), the green LED will remain on continuously when a connection is established. In setup mode, the red LED never comes on. Beeps When the service button is pushed, the sensor device beeps. The sensor device also beeps when monitoring thresholds are set in the sensor device and the device enters (and exits, depending on the configuration) an alarm state. If you do not want to hear alarm beeps, remove the alarm jumper. The alarm jumper is located inside the sensor device, as shown in Figure 4, Figure 11, and Figure 12. Monitoring Thresholds During configuration, battery-powered sensor devices permit you to set temperature and humidity monitoring thresholds in the AMP or in both the AMP and the sensor device itself. In order to achieve maximum benefit from SNS battery sensors, careful thought should be given to where alarm thresholds are set as well as the frequency with which sensor devices report readings to the AMP. If thresholds are set in the AMP, but not in the sensor device, the alarm state is not detected until the sensor device transmits scheduled readings to the AMP and the AMP recognizes that a reading is out of limits. Depending on how frequently the sensor device is configured to transmit readings to the AMP, a period of time may elapse before the AMP creates an alert for the out-of-range condition. If thresholds are set in the sensor device and these thresholds are exceeded or, depending on the configuration, exceeded for a period of time, the sensor device enters an alarm state and transmits readings to the AMP. However, thresholds set in the sensor device can only be changed on a device-by-device basis through reconfiguration.
Features of SNS Battery-powered Sensor Devices Operational Sequences Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 23 Set Monitoring Thresholds to Prevent Loss of Sensitive Assets If you have sensitive assets such as blood, medications, or tissues, you can set up the sensor devices to report readings as many as 15 times per hour and to generate alerts and send notifications as soon as thresholds are reached. Be sure that settings are configured both in the sensor device and in the AMP sensor device page. In this scenario, you will set the sensor’s transmit period to a shorter time, and edit the sensor device’s reporting period to the same number of minutes as the transmit period. Note: Shorter transmit periods (more frequent transmissions) shorten battery life and increase network load. Then, you will use the Battery Sensor Software Configuration utility to set the transmit period in the sensor devices. You will also set the alarm thresholds in the sensor device. If the sensor device detects that a threshold has been exceeded the LED will flash and the sensor will transmit a reading to the AMP, where an alert will be active. See Appendix B: Battery Sensor Configuration Utility on page 57 for instructions on setting these alarm thresholds. Note: Thresholds configured in the sensor device using the Battery Sensor Software Configuration utility can only be changed using the utility. If you relocate the sensor device, for example, moving it from a refrigerator to a freezer, you will need to reconfigure the device using the utility. Operational Sequences Turn on the Sensor Device Place the on/off switch in the ‘on’ position to turn on the sensor device. Normal Operation When the USB Programmer is not plugged into the sensor and the sensor is powered on, the sensor is in Sensor mode. The sensor spends most of its time in this mode in a very low power state (sleep). When a transmit period is due, it powers up the Wifi radio, attempts to link to the specified wireless network, transmits its data and then goes back to sleep. The sensor transmits based on a transmit period or entering an alarm state. The sensor will go through following steps in order to connect to a network and deliver data: 1. Associate 2. Authenticate (depends on the type of security) 3. Request IP from DHCP Server (if set to dynamic IP) 4. Request from Name Server IP address of hostname (if a hostname is used for the Destination address and DNS Server specified). 5. Sensor sends UDP packet with sensor data. 6. Host sends UDP acknowledgement packet. Check-in with the AMP The sensor will initiate a delivery attempt to the AMP, known as a ‘try’, repeatedly (typically every 30 seconds) until either an acknowledgement is received from the host or the number of tries has been exhausted. If no acknowledgement is received, the sensor device will stop transmitting and wait for the next transmit period or when an alarm is triggered. The sensor follows this delivery mechanism for both when the transmit period arrives or for alarm attempts.
Features of SNS Battery-powered Sensor Devices Operational Sequences Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 24 When specifying the setup parameters for a sensor, you must give careful consideration to the needs of your application and battery life. The more often the sensor transmits data because of the transmit period, alarms, or retries, the shorter the battery life. It is recommended that you use the alarm function to transmit sensor data of concern and extend the transmit period to lengthen the battery life of the sensor. If you plan on using DHCP or DNS, it is best to use local DHCP and DNS servers rather than a DNS Server on the internet. The local servers will give better response times compared to the remote servers and thus conserve battery life. Setup Mode If the USB Programmer is connected to the sensor, the sensor is in Setup mode. When in Setup mode and configured properly, the sensor attempts to connect to the network and will remain connected to the network. The sensor will not send sensor data when in this mode. Handle Alarms If alarms are configured in the sensor device, pressing the button cancels the alarm on the sensor device. Change Batteries The sensor device has a built-in battery meter. This meter is based on a count of the sensor device transmissions. This battery information is only an estimate of the remaining battery life. The Battery Sensor Configuration Utility shows the estimated battery expiration and the estimated battery life percentage in the Status page. Refer to Figure 22: SNS Battery Sensor Configuration Utility Status Tab on page 44 and Table 14: SNS Battery Sensor Configuration Utility Status Tab Fields and Values on page 45. When changing batteries, be sure to replace both batteries and reset the battery. See Replace Batteries in Battery-powered Sensor Devices on page 49.
Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 25 Configure Sensors for the Network Regardless of the type of sensors deployed in your SNS Temperature and Humidity sensor network, each sensor device must be configured with the settings of the wired or wireless network in which it will be used. This section covers the following topics: • Select the Configuration Method • Edit Default Sensor Profiles • Configure AC-powered Sensors using Discovery and Auto-Configuration • Set up the Network Connection • Configure AC-powered Sensors using Browser-based Configuration • Configure Battery-powered Sensors with the Sensor Configuration Utility Select the Configuration Method Several methods exist to configure sensor devices. The configuration method you choose depends on several factors such as the type of sensor and the availability of the network at the time of configuration. Table 7 shows the applicability of each method. All methods assume that the sensor is configured with the latest Primex Wireless firmware and that the Default Profile has been set up on the AMP. For information on the Default Profile, see Edit Default Sensor Profiles on page 25.

Configure Sensors for the Network Edit Default Sensor Profiles Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 28 Item Description Audio Reset Period Interval from the time the alarm is cleared at the device by pressing the service button before the device again displays the alarm if the alarm condition persists. At the end of the Audio Reset Period the LED will begin to flash again if the alarm condition persists, even if Enable Audio Alert is disabled (unchecked). Your choices are: Indefinite 15 or 30 minutes 1, 2, 3, 4 hours (AC Single and Dual Probe Temperature sensor devices only) Not Reporting Limit Maximum time that the sensor can go without checking in with the AMP before notification is sent. If this setting is exceeded, the AMP generates the Not Reporting alert if this alert is enabled. Your choices are: No Limit; 30 minutes; 1 Hour; 2 Hours; 3 Hours; 4 Hours; 6 Hours; 8 Hours; 12 Hours; 16 Hours; 1 day Not Reporting Email Address(s) Enter one or more email addresses (maximum 500 characters) separated by semi-colons for the AMP to send notifications if the Not Reporting Limit is exceeded. The Not Reporting alert must be defined in order for the AMP to send the Not Reporting notification. This user receives email in addition to anyone whose email address is defined for the specific alerts. Not Reporting notification is generally sent to the IT person who can repair, replace or reprogram the sensor device. Reporting Interval This field indicates how often the sensor device reports status to the AMP. Your choices are: Every: 4, 5, 10, 15, 20, 30 minutes, 1, 2, 4, 8, 12 hours Note: For battery-powered sensors, this should be the same as the Transmit Period configured in the sensors. Note: AC-powered sensors (and battery-powered sensors with internally configured alarms) also report to the AMP when a threshold or span is exceeded or if the temperature comes back into range. AC sensors also check in with the AMP if power is lost and then restored. All sensors check-in with the AMP if the service button is pushed by the user during normal operation. Logging Interval This field indicates how often the sensor device saves its readings, and is separate from the interval at which the device accesses the network to report readings. If the logging interval is enabled in the sensor and set shorter than the reporting (transmit) interval, the sensor device will report multiple readings per check-in, but will check in less frequently for the same amount of data, thus saving the battery life. (Battery-powered sensor devices only) Connection Attempts Choose the number of attempts, 1-5, the device makes to connect to the AMP for its regularly scheduled reporting. If the device fails to connect after this number of attempts, it waits until its next regularly scheduled report time. (Battery-powered sensor devices only)

After configuring the sensor device, you can edit its settings to assign it a static IP address. If DHCP is not an option, configure sensors using Browser-based Configuration and add the sensor device on the AMP with a static IP address before configuring it. *Access AMP Using: (Device Settings) You may access the AMP via an internal or external IP address. Internal IP address External IP address AMP Alternate 1 (Optional) Select an alternate access method: Internal or External IP address. AMP Alternate 2 (Optional) Select an alternate access method: Internal or External IP address.
Configure Sensors for the Network Configure AC-powered Sensors using Discovery and Auto-Configuration Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 31 Item Description Message Retries Sensors use UDP (User Datagram Protocol) to communicate with the AMP server. UDP does not provide guaranteed delivery, so the sensors can be set to retransmit unacknowledged messages from 1 to 4 additional times before giving up and saving the data to report the next time the sensor connects to the network. Retry Period Sensors can be configured to wait from 5 to 60 seconds before trying to re-send an unacknowledged message to the AMP. Typically 5 seconds is more than sufficient, but longer wait periods can be used if desired on networks with bursts of high activity. Wireless Network Settings 1 Each sensor device can be configured to use up to three different wireless network settings, allowing for backups and fail-over scenarios. If using a wireless network, the first network setting is required. Select from the list of networks configured for the AMP. Wireless Network Settings 2 For the optional, alternate wireless network, select from the list of networks configured for the AMP. Wireless Network Settings 3 For the optional, alternate wireless network, select from the list of networks configured for the AMP. Configure AC-powered Sensors using Discovery and Auto-Configuration Discovery and Auto-Configuration is the preferred method for configuring AC-powered sensor devices. During Discovery and Auto-Configuration, you connect the sensor device to the network. The MAC address of the sensor device is transferred to the AMP, and the AMP downloads the Default Profile as the information by which the device operates as part of the network. If the SNS AMP has been installed and you have a network connection available on the same subnet that the AMP is on, you can use Discovery and Auto-Configuration to configure AC-powered sensors. Note: Discovery and Auto-Configuration assumes that sensor devices connect to the network using DHCP. After sensor devices are recognized on the AMP, you can edit the network settings for each sensor device to assign it a static IP address. If DHCP is not an option, configure sensors using Browser-based Configuration and add the sensor device on the AMP with a static IP address before configuring it. Otherwise, when the sensor checks in after being configured, the AMP will see it as an “unknown” new sensor and will use the default profile to configure it, which will wipe out the static IP address configured in the sensor. See the SNS Temperature and Humidity Sensors User Guide for information on editing a sensor device. Guidelines Before you begin be sure that the following items are available: • Default Profile configured for your network on the AMP. See Edit Default Sensor Profiles on page 25. • A network connection on the same subnet as the AMP • Ethernet cable
Configure Sensors for the Network Set up the Network Connection Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 32 Configuring AC-powered Sensors Using Discovery and Auto-Configuration (Same Subnet as the AMP) 1. Connect the temperature probe to the sensor in the available Sensor Probe jack. 2. Connect one end of the Ethernet cable to the RJ45 port on the side of the sensor device, as shown in Figure 2. Connect the other end of the Ethernet cable to the network on the same subnet as the AMP. 3. Plug the AC adapter for the sensor device into a power source. 4. Plug the AC adapter into the sensor device. The sensor device will display all the segments and then go blank briefly before displaying the temperature. 5. When the sensor display shows the temperature, push and immediately release the button on the front of the sensor. The sensor will emit a series of beeps. The beeps signal the following connection sequence: 1= radio booted, 2 = connected to network, 3 = connected to the AMP. 6. Check the AMP to confirm that the sensor device has checked in. The sensor device appears in the Sensor Devices list with the MAC address in brackets in the Name column. Double-click on the sensor device in the Sensor Devices list to edit information for the sensor, for example, change the name to something meaningful. Refer to the SNS Temperature and Humidity Sensors User Guide for details on editing sensor device information on the AMP. 7. Disconnect the Ethernet cable from the sensor. 8. The Sensor Default Profile is stored in the sensor’s non-volatile memory, so you can unplug and move the sensor device to its installation location. Note: Verify that the first sensor device you configure checks in with the AMP with the correct settings before configuring additional sensors. The first sensor device does not check in or the settings are not correct, troubleshoot the problem or correct the default profile before configuring additional sensors.

When a sensor is configured using Browser-based Configuration, you connect the sensor to a laptop and use the sensor’s web server to enter information for the sensor to connect to the SNS AMP. Later, when the network is available and the AMP is installed, you connect the sensor to the network and force it to check in with the AMP.
Configure Sensors for the Network Configure AC-powered Sensors using Browser-based Configuration Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 35 Note: During this check in, the Default Profile on the AMP will overwrite the settings that you have configured, so before beginning Browser-based Configuration, you first set up the Default Profile on the AMP. For additional information on the Browser-based Configuration Tool, see Appendix A: Browser-based Configuration Tool on page 54. Important • Do not change the Port settings. • Be sure that the Default Profile on the AMP has been configured for your network. • When opening the sensor web configuration page, you may need to disable your laptop or PC’s wireless radio to avoid connecting to other devices with this address. • Obtain the following network information for use when configuring devices for the wireless network. • Wireless network settings: SSID, Security Type, Security Key • Static IP Address, if not using DHCP. If using Static IP, you will need the IP Address, Subnet Mask, and Gateway. When using Static IP, you must specify the IP address of the NTP server numerically. For example, you must enter 10.10.39.100, not ntp.primexwireless.com. Note: If you are not familiar with the network settings, contact your network administrator. Configure the Sensor While in configuration mode, you will use the SNS Configuration Screen, Figure 18, to configure the device for your wireless network. Configuring an AC-powered Sensor 1.

Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 47 Install SNS Sensor Devices and Accessories Once sensor devices are configured, they are ready for installation in their permanent locations. Although not required, installing a thermobuffer with external probe sensor devices helps ensure that sensor readings more closely approximate the temperature of the assets you are monitoring. Install SNS Temperature and Humidity Sensors Specifics of the installation depend on the monitored unit. Installing Sensor Devices 1. For sensor devices with probes, in the monitored unit, locate an existing access hole, drill a new access hole for insertion of the probe, or route the cable through the rubber door gasket. 2. Route the external probe through the access hole. 3. (Optional) Install a thermobuffer. See Install a Thermobuffer on page 47. 4. Mount sensor and dress cable. All SNS AC-powered temperature and humidity sensor devices come with self-adhesive hook-and-loop mounting tape. Alternatively, the sensor device’s base plate has four holes that may be used to mount it with screws. Note: The operating range of the AC-powered temperature sensor device is 32° - 95°F (0° - 35°C). If you’re monitoring temperatures in a freezer, the sensor device must be mounted outside the freezer. 5. Ensure that sensor device is powered on. 6. Activate sensor using the Service button. 7. Log into the AMP and verify that sensor device has checked in and is reporting within expected ranges. Install a Thermobuffer In many environments, normal daily use of refrigerators or freezers results in routinely opened doors, occasionally for prolonged periods when restocking. This may cause air temperature to change drastically and then recover just as quickly when the door closes. Temperature sensors respond to this quick change and can give readings inconsistent with the actual temperature of stored goods. The Primex Wireless SNSGRP SNS Thermobuffer, shown in Figure 24, is used with SNS temperature sensors to simulate the actual temperature of contents within coolers or freezers and limit impact of fluctuating air temperature. This helps provide a higher degree of measurement accuracy and reduces risk of potential material spoilage. When a thermobuffer is in use, fluctuations are minimized so you can rely on the AMP threshold exceeded alerts and do not need to define span exceeded alerts. The thermobuffer features a plastic bottle that can be filled with food grade glycol to delay the temperature spikes found during the replacement of materials or while servicing refrigerators, freezers or walk-in coolers. Whether protecting vaccines, food, medications or other temperature sensitive materials, the thermobuffer can help provide a more consistent measurement of your investments.

Insert the sensor probe through the grommet on the bottle cap with the tip of the probe fully submersed in the glycol fluid. 3. Tighten the sensor grip with a wrench to secure the sensor in place. 4. Set the thermobuffer on a shelf, adhere it to a wall with hook-and loop mounting tape, or attach it to a shelf with standard zip ties. Avoid placing the thermobuffer in direct contact with the sides of the storage unit.
Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 49 Maintain Sensor Devices SNS Temperature and Humidity Sensors require very little maintenance. This section contains the following topic: • Replace Batteries in Battery-powered Sensor Devices Replace Batteries in Battery-powered Sensor Devices Battery-powered sensors use two AA batteries. Batteries are located inside the sensor device (Model SNS2TNS-2, Figure 4; Model SNS2TPH-2, Figure 12) or in an externally accessible battery compartment (Model SNS2TPS-2, Figure 5). When replacing batteries, it is important to reset the battery meter. Resetting the Battery Meter 1. Turn off the sensor. Make sure the USB Programming Cable is disconnected from the sensor. 2. Engage the service button by either pressing the service button or using a magnet with some sensors. 3. Turn the sensor on while the service button is engaged. 4. Wait four seconds. 5. Release the service button. The battery meter has been reset. To confirm that the battery meter has been reset, reconnect the USB Programming Cable to the sensor and view the estimated battery life in the battery sensor configuration utility Status tab. The utility should indicate 100 %. NOTE: When replacing the batteries in a dual battery SNS sensor always make sure you replace both batteries together.

Many of the troubleshooting suggestions given below for battery-powered sensors apply to AC-powered sensors as well. Table 15: Troubleshooting AC-powered Sensors Problem Resolution Cannot access the AMP. Check wireless signal and network interface (wired/wireless) using the browser-based configuration tool.

Check wireless signal and network interface (wired/wireless) using the browser-based configuration tool. Refer to Appendix A: Browser-based Configuration Tool on page 54. Defective sensor Troubleshooting Battery-powered Sensors Overview The SNS Sensor Configuration Utility can be used to help troubleshoot sensor issues with connecting to a wireless network. The troubleshooting suggestions below assume you have the SNS Sensor Configuration Utility installed on your computer and that you know how to use it. When the programming cable is connected to the sensor, the sensor goes into “setup mode”. The sensor continuously attempts to connect to the wireless network and will stay connected until the programming cable is disconnected, or the sensor setup has changed. The sensor is in “sensor mode” when the programming cable is not connected and the sensor power switch is turned on. In “sensor mode”, the sensor remains in a low power state. When ready to transmit, the sensor will turn on, connect, transmit a UDP packet, and then go back to the low power state. General Troubleshooting Suggestions 1. The sensor will not work reliably with signal strengths below about -65 dBm. If the signal strength is smaller than that, the sensor may work marginally or not at all. Obviously the better the signal strength, the better the chance the sensor has at delivering a sensor packet. 2. The signal strength will vary from sample to sample. You should take multiple samples to determine the signal strength. Signal strength is available in the Status tab and the Available Networks window (press the “Find Networks” button in the Setup tab).
Troubleshoot Sensors Troubleshooting Battery-powered Sensors Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 51 3. The red LED on the main sensor board indicates that a transmit attempt has just finished. The green LED on the radio module indicates that radio module is connected to a network. When in sensor mode, the green LED flashes when a connection is made. When in setup mode (the programming cable is connected to the sensor), the green LED remains continuously on when a connection is established. In setup mode the red LED never comes on. In sensor mode the red LED flashes at the end of the transmit cycle. 4. In sensor mode, it can take up to 5 seconds for the transmit cycle to complete. This is from when the service button is pressed to when the red LED is flashed. 5. If the connect time to the network is long (over 4 seconds), the sensor will not be able to connect to the network. If you suspect the connect time to the network is long, use a PC to connect to the network and then measure the connection that a PC takes to verify the connection time. 6. Some access points will move between three channels (typically 1, 6 and 11). The SNS Sensor will work with these access points with the Channel AutoFind feature but the channels that are used must match the channels the sensor is configured for. Troubleshooting Specific Symptoms The list of symptoms includes: • Cannot connect to the wireless network • Can connect to the network but cannot obtain a dynamic IP address • Can connect to the network but host is not receiving UDP packets • Battery Meter indicates a lower battery life than expected • SNS Sensor Configuration Utility cannot find the sensor • SNS Sensor Configuration Utility Says Sensor is Off • Loss of Data When Backup Power Fails Cannot connect to the wireless network 1. Verify that the network exists. 2. Verify signal strength. Use the built in sensor signal strength meter. Use a signal strength meter like a PC running “Network Stumbler”. Determine if adequate signal strength exists at that location. 3. Verify network settings. 4. Make sure the network settings do not exclude 802.11b. Also make sure the router or Access point accept connections of 1 Mega baud. 5. Turn off auto modes in the router or Access Point. The sensor does not support WPA2-PSK TKIP. There are some routers and Access Points where the sensor will connect if the network is set to WPA2-PSK AES and TKIP. Set the Access Point to WPA2-PSK AES. 6. If the sensor was previously connected at one location, but will not connect at the new location, temporarily move the sensor to the previous location and verify operation. It is also possible that a setting at the sensor or on the network has changed. Can connect to the network but cannot obtain a dynamic IP address 1. Verify your network settings. 2. Verify that you are connected to the right network.
Troubleshoot Sensors Troubleshooting Battery-powered Sensors Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 52 3. Use the “Ping From Sensor” function in the utility to ping an address that should be available from the network (verify that the address is ping-able). 4. Use the “Ping From PC” function in the utility to see if your PC can ping an address on that network (your PC must be connected to that network for this to work). 5. Use the “Ping From PC” function in the utility (if this PC is connected) to see if you can ping the sensor when it is in setup mode. Go to the Status tab to determine the sensor’s IP address. 6. Use a static IP address temporarily and connect to the network. Determine if sensor packets are being received by the host. 7. Make sure the DHCP Server has not exhausted the number of assignable IP addresses. 8. It is possible the DHCP Server is taking too long to respond to the request. Can connect to the network but host is not receiving UDP packets 1. Verify your network settings. 2. Verify that you are connected to the right network. 3. Verify that the Destination IP address is correct. 4. If using the broadcast address, verify that the network can support broadcasts. Most routers by default will not route broadcast traffic. 5. If the host will respond to ping requests, use the “Ping From Sensor” function in the utility to have the sensor ping the host. Use the “Ping From PC” feature if this PC is connected or a PC on the network and ping the host. Also, try pinging the sensor when the sensor is in setup mode. 6. Is the host ready to receive the sensor packets? Is the host configured to listen for the UDP packets? Is the host software running? Is firewall software installed at the host that would prevent the UDP traffic? Is there anything on the network that would restrict packets from being routed (like MAC filtering)? 7. Use the “Contact Destination Host” function from the Tools tab. 8. If using a hostname for the destination address: • Make sure the DNS address is correct (whether set as static or obtained through the DHCP server). • Is the hostname being resolved in setup mode? (Use the SNS Sensor, go to the Status tab and examine the Resolved Destination field.) AMP Battery Meter Icon Indicates a Lower Battery Life than Expected Some possible causes of low battery life: 1. The transmission count was not reset when the batteries were last changed. 2. The transmit period is too short. 3. The service button was pressed a lot for this sensor. 4. There were many alarms for this sensor. 5. There were many tries for the sensor.
Troubleshoot Sensors Troubleshooting Battery-powered Sensors Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 53 SNS Sensor Configuration Utility Cannot Find the Sensor 1. Make sure the programming cable is plugged into the sensor. 2. Does the red LED in the programming cable flash when doing an operation? 3. Disconnect the programming cable from sensor and connect again. 4. Disconnect the programming cable from sensor and then disconnect the cable from the PC. Wait 30 seconds. Plug cable back into PC and into sensor. 5. Reboot your computer. 6. Use an externally powered USB Hub. Your computer may not be supplying enough power through the USB port. SNS Sensor Configuration Utility Says Sensor is Off 1. If the utility gives the following error “Sensor is possibly powered off!” disconnect the USB Programming cable from the sensor, turn on the sensor, wait 5 seconds and connect the USB Programming cable. 2. Be sure that you are turning the sensor on. See Features of SNS Battery-powered Sensor Devices on page 18 for the location of the On/Off switch. Long Connect Time In some networks, one of the optional components of the connect time may take too long to perform on a consistent basis. If the average connection time is too long, it is important to try isolating the cause. To isolate the cause, try temporarily turning off one of the options and then re-measuring the average connection time. For example, try setting the dynamically assigned IP address as the static address temporarily, or try using a Destination IP address instead of the hostname address temporarily. Loss of Data When Backup Power Fails All data being collected by the probes is stored in non-volatile memory. This data will be lost if backup power fails. If AC power is restored before backup power fails and the temperature stayed within the set limits, all of the readings will be sent to the AMP as a single check-in with the current temperature for entire duration of the power outage. If a high or low limit is crossed while running on backup power, the data is saved to EEPROM with a timestamp. This data is erased in the event that backup power fails. If backup power does not fail, these archived readings are sent to the AMP as well as current temperature readings when AC power is restored. This provides a view of when temperatures went in and out of limits and for what duration.

You use the SNS Battery-powered Sensor Configuration Utility Alarm tab to program alarms in battery-powered sensors. The utility will display the Alarm Tab window if the sensor supports alarms. If the sensor has more than one I/O point that supports the alarm function, then the utility displays the alarms settings in individual tab windows. A name will be given for the I/O point, for example, Temperature 1, and displayed on the tab at the side of the window for each I/O point Figure 34: Alarm Tab for Dual Temperature Sensor The settings for dual temperature sensor are similar to the single temperature sensor. The difference is that there are two separate probes to set alarms for, Temperature 1 and Temperature 2. Set thresholds as desired.

Ping from Sensor: When the Ping button is pressed, the sensor uses either the IP address in the IP Address field or the current address in the Destination IP field in the Setup tab and pings that specified address. Once the ping operation is complete, the utility indicates either failed or success, and specifies the IP address in the Result field. Ping from PC: When the Ping button is pressed, the sensor uses either the IP address in the IP Address field or the current address in the Destination IP field in the Setup tab and pings that specified address from the local PC. Once the ping operation is complete, the utility indicates either failed or success, and specifies the IP address in the Result field. Destination Test The Utility will instruct the sensor to send a special packet to the Destination Address. If the Destination responds with an acknowledgement, the Utility will indicate success otherwise the Utility will display “Failed” in the Result field. Use the Contact Destination Host function to confirm that the sensor is sending packets to the Destination. Note: the Destination must be capable of responding with an acknowledgement in order for this function to work.
Appendix B: Battery Sensor Configuration Utility User Interface Primex Wireless, Inc. SNS™ Temperature and Humidity Sensors Installation Guide 64 Item Description Test Connect Time The "Test Connect Time" function tests how well the sensor connects to the network. Consistent connection performance is essential for longevity of sensor battery life. This test will give an indication of how well the sensor connects to the network thus giving an indication about battery life. If the average connection time is above 6 seconds, the sensor battery will be exhausted before the battery meter indicates. Refer to Table 17 for the components of connect time. Start Press the Start button to start the test. The utility will repeatedly attempt to connect to the network with one second between connection attempts. The utility will show a count of connection attempts, the last connect time, the average, minimum and maximum connect times. The utility will show the history of connect attempts as a bar graph. Each bar graph is the number of seconds for the attempt. The utility will show a grey bar (at full scale) for failed connection attempts. Failed connection attempts are not factored in the statistics. Table 17 lists the components of the Connect Time.
