and system and send the data measured to the Senquip Portal or a server of your choice. The Senquip QUAD is designed for applications where the telemetry device needs to be hidden, is in a metal enclosure, and so needs external antennas. Built in sensors allow measurement of supply voltage, battery voltage, time, position, speed, ambient temperature, pitch, roll and pressure. Interfaces are provided for RS232, RS485, MODBUS, CAN bus, Bluetooth, 4-20mA, pulse, frequency, and voltage. Data measured by the Senquip QUAD is transmitted to the internet via Wi-Fi or 4G LTE4 and can be delivered to the Senquip Portal or to your own server or SCADA system. Power to the Senquip QUAD can be supplied by a solar panel, or with 10V to 75V DC. If a solar panel is used, an internal LiPo battery will keep the device powered during periods without sunlight. 1 Senquip QUAD User Guide, Release Senquip telemetry devices are programmable with JavaScript.

Getting Started Chapter 3 Power Supply The Senquip QUAD has been designed to oer maximum exibility in terms of power supply require-

ments and is able to run o permanent power and solar. 3.1 Permanent power A wide input range of 10-75V operation allows for use in automotive, industrial and telecoms applica-

tions. System power is backed up with an internal lithium polymer rechargeable battery in the event of power outages. Supply voltage is monitored to a resolution of 100mV and can be reported on a periodic basis if enabled. The supply voltage input is reverse polarity protected and is resistant to damage from static and surge. The Senquip QUAD can be used with a solar panel as a source of power. When used with solar, an internal LiPo backs the device up overnight and during cloudy weather. When running on solar, the panel needs to be able to collect enough energy during sunlight hours to power the device through the night and on cloudy days. Keep in mind that solar panels will tend to get dusty and so should be over-rated to avoid regular maintenance. A typical 12V solar panel used to power the Senquip QUAD along with its specications is shown below:

Figure 3.1. Typical Senquip QUAD solar panel Parameter Maximum power Voltage at maximum power Current at maximum power Open-circuit voltage Short-circuit current Specication 10W 17V 0.56A 21.6V 0.68A 27 Senquip QUAD User Guide, Release Width Height 357mm 302mm The above solar panel was tested with a Senquip QUAD measuring and reporting 2 input voltages, ambient temperature, ambient pressure and thermocouple temperature at an interval of 5 minutes. To conserve energy in what was a xed location test, GPS location was measured every 20 base inter-

vals or 100 minutes. The results were transmitted over 4G LTE or Wi-Fi at 5 minute intervals. The solar panel was sucient to power the Senquip QUAD. 3.2 Internal rechargeable battery An Internal 3.7V, 1800mAh rechargeable Lithium Ion Polymer (LiPo) battery is charged from system power, making the device ideal in applications where power is intermittent such as solar. The LiPo battery can be fully recharged within 4 hours of system power being connected. If the internal LiPo has been allowed to completely discharge; when power is rst applied to a Senquip QUAD, the battery will go into a pre-charge mode where the battery is charged to a minimum level before the device starts operating. Pre-charge mode is identied by a slow ash on the green LED with the orange LED o. An internal protection circuits prevent damage to the LiPo battery in the event of a short circuit or due to excessive discharge. A temperature monitoring circuit terminates LiPo battery charging at temper-

atures below 0 C and above 45C. It is recommended that the LiPo battery be replaced after three years of use or more regularly if the device routinely operates in extended temperatures. The LiPo battery should only be replaced by a Senquip replacement part and should only be installed by a suit-

ably trained technician. System voltage which is closely related to the LiPo battery voltage is monitored to a resolution of 100mV and is reported at the base interval.

Power Supply Senquip QUAD User Guide, Release 3.3 Power consumption The Senquip QUAD has been designed to be suitable for use in applications where permanent power is not available and solar and other sources of intermittent power are the only source of energy. Factors aecting power consumption include the rate at which sensor measurements are made, the number of transmissions of measured data and which internal and external sensors that are connected. Broadly, the state of the Senquip QUAD can be divided into three modes: sleep, measurement and transmission. Sleep mode is by far the lowest power state where most internal sensors are turned o and the device is waiting for the next measurement period. During a measurement period, the sensors are turned on and power consumption increases dramatically. The actual power consumed during a measurement phase depends on the power requirements of connected sensors and the duration for which they are turned on. For instance, a 4-20mA pressure sensor will, by default, draw between 4mA and 20mA of current when turned on. The sensor will clearly use less energy when measuring 4mA than when measuring 20mA. Transmission is the most energy intense operation performed by the Senquip QUAD. During transmission, the Wi-Fi and or 4G LTE radios are turned on and data is transmitted. Limiting the length of radio transmissions has a signicant impact on energy consumed. The following strategies can be used to limit power consumption:

Limit the rate at which measurements are taken - if the parameter being measured changes slowly, then measuring it regularly will consume additional energy without a benet. Turn o sensors that are not required - the Senquip QUAD contains a rich set of internal sensors. If for example, the GNSS is not required, turn it o. Choose external sensors carefully - a 4-20mA sensor may use more energy than a voltage output sensor. Limit the number of daily transmissions - consider only transmitting data when warning and alarm conditions are breached. Ensure that the device is placed in a position where 4G LTE, Wi-Fi, and GNSS reception is opti-

mal. Far more current is consumed when transmitting and receiving in a poor signal environ-

ment. Measured sleep, measurement, and transmission current is given in the table below. The measure-

ments in the table represent current owing from the internal LiPo battery at 3.5V, with external power to the device removed. Except where stated, the GNSS is assumed o. Actual values will depend on the power source, selected measurements, battery charge state, distance from Wi-Fi or 4G LTE source and temperature. Mode Sleep Measurement (no external sensors, GPS o) Measurement (no external sensors, GPS cold start) Transmit (WiFi from sleep) Transmit (4G LTE from sleep) Time Current Up to 24 hours 65uA 0.5s 40mA 54s 70mA 97mA 8s 120mA 20s 3.4 Freight mode When shipping a Senquip QUAD, it is important that the device is placed in freight mode. In freight mode, the device is put into sleep mode to reduce battery drain to the minimum, and all transmitting devices are turned o. The Senquip QUAD will exit freight mode when it detects that power has been 3.3. Power consumption 29 Senquip QUAD User Guide, Release re-connected.

1. Disconnect all wires including the power input. 2. Press the Enter Freight Mode button below. 3. Wait 5 seconds, then check the Status and Network lights remain o. 4. Conrm freight mode has been entered by pressing the Reset button; there should be no response from the device. Figure 3.2. Entering freight mode Note A shortcut is provided where pressing the Setup button three times, when in setup mode, will cause the Senquip QUAD to enter freight mode. Conrm freight mode has been entered by pressing the Reset button. 30 Chapter 3. Power Supply Chapter 4 General Setup 4.1 Measurement and transmit intervals The Senquip QUAD can be congured to take periodic measurements and then to transmit those measurements at various intervals or on exception. When not measuring or transmitting, the Senquip QUAD will remain in a very low power state, referred to as sleep. For example, a device can be congured to measure temperature at 1 minute intervals, but only to transmit the temperature once an hour or if a warning or alarm level is exceeded (an exception occurs). By allowing a more regular measurement interval and a less frequent transmit interval, the device is able to reduce power consumption by remaining asleep, thereby maximising battery life. In the event of an exception, a more regular transmit rate can be selected. 31 Senquip QUAD User Guide, Release Figure 4.1. Timing owchart Green: Lowest power state; aim to congure the Senquip QUAD to spend maximum time in this state. Orange: Moderate power usage; try to reduce the number of times that the Senquip QUAD wakes to measure sensors. Pink: Highest power consumption; only transmit data when required. To allow exible measurement and transmit intervals, whilst ensuring the lowest possible power consumption, the Senquip QUAD has three global and one per-peripheral measurement interval settings. 32 Chapter 4. General Setup Senquip QUAD User Guide, Release Base-Interval The base-interval is the period of time after which the Senquip QUAD will wake from sleep in order to check if there are any measurements to perform or if it is time to transmit the latest measured data. In a system where measurements are required often, the base-interval can be as low as 5 seconds. In systems that are slow to respond, the base interval can be as high as 24 hours. It makes sense to set the base interval as long as possible to enable the device to spend as much time as possible in a low-power sleep state. Each peripheral, whether internal to the device, or attached to the external interface, can be set to only be measured after a number of base-intervals. If a particular peripheral has the interval setting set to 1, then it will be measured at each base-interval. If the interval is set to 0, then that particular periph-

eral will be turned o. Each time a measurement is taken, the results will be compared with alert, warning and alarm conditions and if an alert or exception occurs, the results will immediately be transmitted. Note if a base-interval of less than 10 seconds is specied when the Senquip QUAD is communicating via Wi-Fi or 120 seconds over 4G LTE, the device will remain awake at all times. Note if the enabled measurements take longer to complete than interval at which they are scheduled, the device will not return to sleep and measurements will be sent as fast as possible. This is most likely where the GPS and serial devices are enabled. Transmit-Interval The transmit-interval is the time between message transmissions. It is a multiple of the base interval and is set as a number of base-intervals. All enabled measurements will be trans-

mitted at the transmit-interval. For example, if the base-interval is 1 minute and the transmit-interval setting is sixty, then all the latest measurements will be transmitted every 60 minutes. In cases where the Senquip QUAD is congured to measure more often than to transmit, measured data can be saved and transmitted in batches. It is more ecient to batch messages and transmit less regularly than to send individual measurements. Use this option where power use needs to be minimised but all measured data needs to be retrieved. Note if during a measurement interval, an exception occurs, the device will immediately transmit the measured data and will switch to the exception interval. Note if measurement and transmission intervals coincide, measurements will be taken before trans-

mission to ensure the latest values are transmitted. Exception-Interval If a warning or alarm occurs, the transmit-interval can be shortened in order that measurements are transmitted more often. The exception-interval is a multiple of the base interval and sets the time between message transmissions when an exception is current (warning or alarm). For example, if the base-interval is 1 minute and the transmit-interval setting is sixty, under normal circumstances, measurements will be transmitted every 60 minutes. If the exception-interval setting is 5, then when a warning or alarm condition is current, measurements will be transmitted at 5 minute intervals instead of 60 minute intervals. Note Only exceptions, which are warnings and alarms will trigger the exception-interval; alert condi-

tions such as exit from a geo-fence will not. If, on any base interval, a new exception or alert is detected, an immediate transmission will be made regardless of the transmit-interval. 4.2 Power supply An alert can be generated when the external power source is lost, or the internal LiPo battery is running low. If enabled, the external power loss alert will be triggered as the voltage drops below 4.2. Power supply 33 Senquip QUAD User Guide, Release 9.5V. In order to conserve energy, the Senquip QUAD can be congured to enter hibernate when external power is lost. In this mode, the device will wake on its usual base interval, but if power is still lost, it will go back to sleep. A number of base intervals that occur before the device enters hiber-

nate can be set. This allows the device to continue operating for a period of time after power is lost. The Senquip QUAD can be set to wake from hibernate if motion is detected by the internal accelerom-

eter or if power is restored. In hibernate mode, a transmission is made once every 6 hours to allow the user to verify that the device is still functional. In the case of the internal LiPo battery being low, this may indicate a faulty, under-rated or dirty solar panel or permanent loss of external power. If the power loss alert is enabled where solar panels are installed, an alert should be expected as clouds move over or the sun sets. Note If Device Always On and Sleep on Power Loss are both selected then the Senquip QUAD will remain awake as long as it is powered; the device will sleep when power is removed. 4.3 Settings A full list of general settings is given in the table below.

General Setup Chapter 5 Internal Sensors 5.1 Light sensor The Senquip QUAD is equipped with an internal light sensor that is used to activate the setup func-

tions when the lid is opened and to detect tamper attempts. The light sensor is sampled on a regular basis and does not have an associated measurement interval. An alert can be generated when the lid is opened and the device detects light. Note A tamper alert, if enabled will be triggered by a tamper attempt or an authorised entry to change settings. A full list of light sensor settings is given in the table at the end of the chapter. 5.2 Accelerometer The Senquip QUAD has an integrated 3-axis accelerometer. The accelerometer allows for angle measurement, movement detection, harsh-usage monitoring and utilisation calculation. To provide more accurate measurement for pitch, roll and angle measurement, each time the accelerometer is measured, 10 samples will be taken at 1 msec intervals and the average will be returned as the measured value. Pitch, roll and angle will be calculated from the average acceleration. Raw accelerometer data in the X (through the lid), Y (horizontally through the device) and Z (verti-

cally through the device) are available and are delivered in Gs. These values can be useful, for instance where an incident is being re-created from force data. Note Incident recreation using force data requires high speed sampling. Please contact Senquip to discuss your application. When looking at the front cover, positive pitch is described as the top of the Senquip QUAD tilting towards the observer. In the same scenario, negative pitch is described as the top of the cover moving away from the observer. 37 Senquip QUAD User Guide, Release Figure 5.1. Denition of pitch When looking at the front cover, positive roll is described as the top of the Senquip QUAD rotating towards the right. In the same scenario, negative roll is described as the top of the cover rotating towards the left. Figure 5.2. Denition of roll Pitch and roll are useful in applications where objects to which the Senquip QUAD is attached have a denite front, back, left and right; for instance a vehicle. For objects like a pole, the user may be more interested in the angle of the pole to vertical. In these applications, the tilt may be more useful than pitch or roll. 38 Chapter 5.

The fastest possible measurement rate is achieved by setting the interval to 1 in which case measurements will occur on every base interval. To reduce power consumption, the measurement rate can be turned down by increasing the interval. Warning and alarm thresholds for pitch, roll and angle can be enabled. Once enabled, each time a measurement is completed, the returned value will be compared with minimum and maximum warning and alarm thresholds. If a warning or alarm level is breached, a message will immediately be transmitted. As long as the warning or alarm condition persists, messages will be transmitted at the exception-interval rather than the transmit-interval. Hysteresis can be specied in 1 degree incre-

ments, to prevent multiple alarms in the presence of vibration. The accelerometer is able to detect motion and shocks due to harsh usage even during sleep. If motion or shock monitoring is enabled and either of those events occurs, a ag will be set. Event ags are checked at each base-interval and if one exists, an alert message can be scheduled to be sent at that time. The threshold as well as time for which an activity must be present can be set for both motion and shock monitoring. Note Pitch and roll warning and alarm levels can be positive or negative. Angle warning and alarms can only be positive. 5.2. Accelerometer 39 Senquip QUAD User Guide, Release Vibration can be used as a trigger to count hours. This may be useful where the number of hours that an engine is running needs to be calculated. A full list of accelerometer settings is given in the table at the end of the chapter. 5.3 Pressure sensor The Senquip QUAD contains provision for a built-in pressure sensor for measuring atmospheric pres-

sure and short term height change. Although the enclosure is rated to IPX7, an integrated moisture resistant gore-vent allows internal and external pressure to equalise, meaning accurate atmospheric pressure can be measured. Note The pressure sensor is not tted by default, contact Senquip for ordering options. 5.3.1 Specication Parameter Specication Pressure range Temperature range Absolute accuracy (0 to 65 deg C) +-1hPa Relative accuracy (25 to 40 deg C) +-0.12hPa, equivalent to +-1m altitude Absolute maximum pressure 300 - 1100 hPa

val. To reduce power consumption, the measurement rate can be turned down by increasing the interval. Warning and alarm thresholds for pressure can be enabled. Once enabled, each time a measurement is completed, the returned value will be compared with minimum and maximum warning and alarm thresholds. If a warning or alarm level is breached, a message will immediately be transmitted. As long as the warning or alarm condition persists, messages will be transmitted at the exception-interval rather than the transmit-interval. Hysteresis can be specied in 1 kPa increments, to prevent multiple alarms in the presence of uctuating pressure, for instance due to wind. A full list of pressure sensor settings is given in the table at the end of the chapter. 5.4 Magnetic switch The Senquip QUAD contains a built-in hall-eect sensor that acts as a magnetic switch. When the switch detects a magnet, the Senquip QUAD can be made to enter setup mode, wakeup, or trigger a function in a script. 40 Chapter 5. Internal Sensors Senquip QUAD User Guide, Release Figure 5.4. Location of magnetic switch 5.4.1 Settings Three actions are available when the magnetic switch is activated. Setup: Put the device into setup mode. Identical to pressing the Setup button. If the device is asleep, it will wake and enter Setup Mode. Wake: Wake the device up and perform a measurement cycle. There is no action if device is already awake. Trigger: Wake the device if asleep. Trigger TP0 before rst measurement cycle. TP0 should be handled in a script. All: All actions above. Wake device if asleep. Enter setup mode. Trigger TP0 before rst measure-

ment cycle. 5.5 Temperature sensor An integrated temperature sensor allows for measurement of ambient temperature. Please be aware that the temperature sensor will measure the temperature inside the Senquip QUAD enclosure; this temperature can be subject to uctuations, for example when the internal lithium ion battery is charging and so the environment within the device heats up. For accurate external temperature measurement or to measure a wider range of temperatures, use an external temperature sensor. 5.5.

Hysteresis can be specied in 1C increments, to prevent multiple alarms in the presence of uctuating temperature. A full list of temperature sensor settings is given in the table at the end of the chapter. 5.6 GPS Models of the Senquip QUAD that have 4G LTE connectivity also have an integrated Global Naviga-

tion Satellite System (GNSS). The GNSS receiver, allows for position and speed based reporting. The internal GNSS received uses GPS, GLONASS, BeiDou and Galileo satellites to ensure high accu-

racy measurement and fast time to rst x. Data available from the GPS includes:

Latitude, longitude and altitude Speed (km/h) and bearing Date and time Number satellites being tracked In order to utilise GNSS, the antenna needs to be mounted with clear visibility of the sky. Plastic and breglass roof sheeting will have a minimal eect on GNSS performance whereas reinforced concrete and metal roofs will render the GNSS inoperable. Good GNSS signal quality will result in quicker time to position acquisition and lower power use. 5.6.1 Specication Parameter Specication Time to rst x from power up Typically 60 seconds Position update rate Horizontal position accuracy Vertical position accuracy Horizontal speed accuracy Maximum 1Hz Typically +-5m (<2.5m CEP-50) Typically +-20m 1km/h 42 Chapter 5. Internal Sensors Senquip QUAD User Guide, Release 5.6.2 Settings Measurements can be scheduled as a multiple of the base-interval. The fastest possible measurement rate is achieved by setting the interval to 1 in which case measurements will occur on every base inter-

val. To reduce power consumption, the measurement rate can be turned down by increasing the interval. The GNSS is a high power peripheral and so use should be limited when running on battery power. Figure 5.5. GPS alert parameters The GNSS can create an alert based on position and speed. A known position (expected latitude and expected longitude) can be specied and if the device moves a particular radius from that point, an alert can be raised. Hysteresis can be specied in 1 meter increments to prevent multiple alerts, for instance as a boat swings on a mooring near the edge of the allowed radius. Likewise, a maximum speed can be specied and if the device exceeds that speed, an alert will also be raised. Speed hysteresis can be specied in 1km/h increments, to prevent multiple alerts as the speed uctuates at the alert point. The time that GNSS speed exceeds 2km/h can be counted and used to calculate machine utilisation. Note In the example above, the Senquip QUAD could also report bilge water level, solar battery voltage and a host of other parameters associated with the yacht. A full list of GNSS settings is given in the table at the end of the chapter. 5.7. Bluetooth interface 43 Senquip QUAD User Guide, Release 5.7 Bluetooth interface The Senquip QUAD has a Bluetooth peripheral that can transmit and receive Bluetooth Low Energy

(BLE) advertising packets. BLE beacons typically use the advertising packets to communicate measured data such as temperatures, voltages, movement, and battery voltage. BLE tags are a special type of beacon that typically only contain identication information and are used to locate items. BLE beacons send advertising messages at dierent rates. Some report every second and some may be every minute or more. Battery operated BLE devices tend to send at lower rates to save power. Some BLE device are smart and will slow their send rate if they are not being used. A tire pressure moni-

toring device may stop sending if the tire is not rotating. Typical protocols used in advertising packets include Eddystone and iBeacon. The Senquip QUAD supports both. The BLE beacons from ELA shown below enable identication, and measurement of temperature, humidity, voltage, switch position, and more. Figure 5.6. Example BLE beacons from ELA The Senquip QUAD will report the beacon address, data, and the strength of the received signal. The address (or identier) is unique and allows individual tags to be recognised. The data may contain battery voltage, temperature, humidity, or any other data being conveyed by the beacon. The receive signal strength (RSSI) gives an indication of how strong the signal from the beacon is. For details on using the Senquip QUAD as a BLE beacon to transmit custom advertising packets, please refer to the Senquip Scripting Guide. Note The BLE module and Wi-Fi module share a common radio. BLE operation will work best when 44 Chapter 5. Internal Sensors Senquip QUAD User Guide, Release the Senquip QUAD is operated using a cellular network rather than Wi-Fi. 5.7.1 Specication 5.7.2 Settings Parameter Specication Bluetooth version 4.2 Measurements can be scheduled as a multiple of the base-interval. The fastest possible measurement rate is achieved by setting the interval to 1 in which case the Bluetooth peripheral will be sampled on every base interval. To reduce power consumption, the measurement rate can be turned down by increasing the interval. When active, the Bluetooth peripheral will scan for all advertising packets. In a typical environment, phones, computers, and other devices are all advertising. The Senquip QUAD Bluetooth peripheral could easily report a dozen Bluetooth devices even when the one you are searching for is o. A lter allows only the required Bluetooth devices to be reported by lling in the Address Capture List. Required addresses should be entered in hexadecimal and should be separated by commas. When the Senquip QUAD wakes for the next measurement interval, the Bluetooth peripheral will be sampled until all the messages listed have been found or the Capture Time has been reached. If multiple messages with the same identier are required in a single measurement interval, place a *

followed by the number of messages of that identier to be returned after the identier in the list. For example: 98588A10375E*4, 98588a103777, 98588a103888*10 will return 98588A10375E four times, 98588a103777 once and 98588a103888 ten times. Leave the ID Capture List blank to receive all messages. The Capture Time setting can be used to set a timeout after which the Bluetooth peripheral will stop listening, allowing the device to transmit received messages and return to sleep. Capture-time can be used as a mechanism to allow the Senquip QUAD to sample the environment for devices for a dened time-period.

Internal sensor settings 47 Senquip QUAD User Guide, Release 48 Chapter 5. Internal Sensors Chapter 6 External Sensors 6.1 Inputs and Outputs The Senquip QUAD has 5 multifunction Input/Outputs that can be individually congured. Pin Channel 3 4 5 6 7 IO 1 IO 2 IO 3 IO 4 IO 5 Each of the 5 IO can measure:

analog voltages, currents into and out of the terminals, frequencies, pulses, duty cycle, digital ON or OFF state. Each measurement can be calibrated and alerts of type info, alert, warning, and alarm can be set. The IO can also be used as outputs and can be switched to:

OFF - high impedance, Vin - connected via a switch to Vin, GND - connected via a switch to GND, Vset - connected to an internal congurable voltage source, PULLUP - an internal pullup resistor is enabled. Vset is an internal voltage source that can be congured in General IO settings to be between 5V and 25V. Vset is typically used to power external sensors. Vset is backed up by the internal LiPo battery and so will continue to operate if power to the device is intermittent, for instance if powered by solar. The setting for Vset voltage is used to control the feedback loop of a boost converter acording according to a set of characterisation data. The voltage that appears on the output may vary by approximately 100mV. A short dead-time is inserted when switching between IO states to prevent high current ows during 49 Senquip QUAD User Guide, Release the transition from Vin and Vset to ground and ground to Vin and Vset states. The input and output functionality are independant and can be enabled simultaneously. You can for instance switch an output to Vin, measure the voltage on the output to conrm and measure the current owing into the output. Each IO pin can supply up to 100mA from either Vin or Vset and can sink 250mA to ground. The IO are able to switch inductive loads such as relays; it is recommended that yback diodes always be used with inductive loads. The inputs are protected against over-voltage events to 85V and against static discharge. Note Vset can provide a maximum of 100mA across all IO pins. All parameters are measured at the same time, so for instance an input can report measuring 15V with a 20mA current owing. Settings are available to limit which of the measured parameters are trans-

mitted at the end of each measurement cycle. Limit the data sent at the end of a measurement cycle by only selecting the measurement types that you require. A simplied internal architecture of the IO module is shown below. Figure 6.1. Simplied internal IO architecture Each IO can be congured to cause the device to enter hibernate mode on a high to low voltage level change on the associated pin. Likewise, the device can be made to wake from hibernate on a low to high transition on the associated pin. If these functions are selected, the pullup associated with that 50 Chapter 6. External Sensors

Senquip QUAD User Guide, Release IO channel will be enabled. 6.1.1 Powering external devices IO on the Senquip QUAD can be used to power and provide signals to external sensors, relays, lights, buzzers, and other devices. To permanently power an external device by supplying it with a voltage, set the IO Default State to VIN or VSET in which case the connected device will be permanently powered. To power a device by connecting it to ground, select GND as the Default State. The default state will continue to be applied between measurement cycles. Alternatively, the IO can made to switch power on only at a measurement cycle, and for a dened period. To enable switched power, set the default for the IO to OFF and enable the Measurement State as VIN or VSET. Set the Measurement Time as the time for which the externally connected sensor must be powered before being measured. This time is typically the boot time for a sensor. In this case, Vin or Vset will only be made available on the IO during a measurement interval and for the time speci-

ed. This is the preferred method for installs that are solar powered or have intermittent power. Measurement of CAN, RS232, and RS485 are delayed by the longest of all specied measurement times to allow for the case where an IO is being used to power a serially connected device. The gure below shows an RS232 sensor that is powered by IO5 and measured on the RS232 port and a relay that is energised by setting an IO to ground. Figure 6.2. Powering external devices on an IO Note Where switched power is used to power a sensor that is read by another input, the Measurement Time specied for the IO and the input must be the same to ensure that the sensor is powered when measured. For advanced users, the state of an IO can be switched from within a script. This allows for the control of complex sensors and systems and precise timing. If changes to the IO are made from within a script, the default will only be re-applied the next time the device boots. Output states are held when the Senquip QUAD enters sleep. 6.1. Inputs and Outputs 51 Senquip QUAD User Guide, Release 6.1.2 Current Measurement Loop powered (2-wire) and externally powered (3-wire) 4-20mA devices can be used with the Senquip QUAD. For 2-wire devices, Vin or Vset power can be supplied by an IO and the current drawn measured by that same IO. A typical 2-wire install is shown in the gure below. Figure 6.3. 2-wire 4-20mA device install 3-wire devices are externally powered as they typically draw more than 4mA at a minimum and so are not suitable for loop powering. The Senquip QUAD can power a 3-wire device with Vin or Vset from one IO and measure the output current on a second IO. A typical 3-wire install in shown in the gure below. 52 Chapter 6. External Sensors Senquip QUAD User Guide, Release Figure 6.4. 3-wire 4-20mA device install Current out of the IO terminal is dened as positive (2-wire) and current into the terminal (3-wire) is dened as negative. Although optimised for 4-20mA, the IO can measure currents in the range

-100mA to 100mA. 6.1.3 Pulse Count Measurement The Senquip QUAD can count pulses from devices like water-meters, rain guages, and speed-sensors. The inputs can be from voltage free contacts like reed switches, hall eect sensors, or pulse trains from powered devices. When connecting to voltage free switches, am optional pullup (wetting) resistor can be enabled in the settings. The Senquip QUAD can count pulses while awake and between cycles when sleeping. Although all IO can count in a very low power mode, IO1 and IO2 have additional circuitry that allows ultra low power pulse counting. Along with a total pulse count, frequency and duty cycle are also measured at the measurement interval. The gure shows how to wire a voltage free contact and powered pulse train to the Senquip QUAD IO. 6.1. Inputs and Outputs 53 Senquip QUAD User Guide, Release Figure 6.5. Pulse counting Calibration Calibration can be applied to each measurement so that the value returned by the Senquip QUAD is in units that are meaningful in the end application. For instance, a fuel level sensor that outputs a voltage between 0 and 5V may represent a level between 0 and 100 litres of diesel. The voltage measurement can be calibrated to convert from Volts to the more meaningful unit of litres. In any system, the measurement instrument (the Senquip QUAD), the sensor and possibly the measured value will be subject to errors that may accumulate to reduce accuracy. In a system that measures uid volume in a 100 litre tank using a 4-20mA sensor, oset errors may result in a non-zero or negative reading when the tank is empty. Sensor gain may also not be perfectly linear and so a 1 litre change may be measured dierently when the tank is empty versus when it is full. The sensor may report in inches of liquid height where a more meaningful unit may be litres. To achieve an accu-

rate and meaningful measurement, a calibration can be performed. In this example, the tank could be calibrated by adding a small amount of liquid, say 10 litres at which point the current measured may be 4.1mA. Now add more liquid to take the level to say 80l. The sensor now reads 16.2mA. The calibration would then be lled into the IO setting as shown below:

Once enabled, each time a measurement is completed, the returned value will be compared with low and high warning and alarm thresholds. If a warning or alarm level is breached, a message will immediately be transmit-

ted. As long as the warning or alarm condition persists, messages will be transmitted at the exception-interval rather than the transmit-interval. Note If calibration has been applied, then the warning and enable thresholds should be set in the cali-

brated units. To set a high level warning or alarm level only, set the low level to a value that is impossible to achieve. For instance to set a high only warning at 50V, set the low warning to -1V which is an unachievable value. Hysteresis can be specied in increments of the specied unit, to prevent multiple alarms in the pres-

ence of electrical noise. Figure 6.6.

A full list of IO settings is given in the table at the end of this chapter. 6.2 Serial interface The serial port can be used to capture data that is sent from an external system or to interface to a MODBUS sensor. The serial port occupies pins 6 and 7 on the interface header. The pins have functions that depend on the chosen interface as shown in the table below. When RS485 mode is chosen, an optional 120 termination resistor can be selected. Interface type Pin 6 function Pin 7 function Transmit (Tx) RS232 RS485 RS485-A Receive (Rx) RS485-B Note RS485-B is sometimes referred to as D+ or TX+/RX+ and RS485-A as D- or TX-/RX-. The RS485 receiver supports up to 256 nodes per bus, and features full failsafe operation for oating, shorted or terminated inputs. Interface pins are protected against electrostatic discharge up to 26kV, whether the QUAD is powered or unpowered. 6.2.1 Specication Parameter RS232 transmitter output low voltage (typical) RS232 transmitter output high voltage (typical) RS232 Input threshold voltage RS485 dierential output voltage (minimum with load resistance 120) +2V RS485 dierential input signal threshold Maximum nodes in RS485 mode RS485 termination resistor

val. To reduce power consumption, the measurement rate can be turned down by increasing the interval. In serial capture mode the measurement interval can be used to reduce the number of readings being provided by a connected sensor or system that may be permanently powered. If for instance, a connected system is sending a message every second but it is only required to be read and trans-

mitted every minute, the measurement interval can be set to 1 minute in which case the device will wake on the minute interval, receive a message and return to sleep thereby missing the other 59 messages sent by the attached system. Since serial packets cannot be interrogated by the Senquip QUAD without a customised script, it makes sense to set the measurement interval to the same as the transmit interval in most cases. 6.2. Serial interface 57 Senquip QUAD User Guide, Release The serial port on the Senquip QUAD can be congured as an RS232 or RS485 hardware interface using the type option. If RS485 mode is selected, an optional 120 termination resistor can be selected by selecting the Termination resistor option. The purpose of the termination resistor is to match the impedance of a transmission line to the hardware impedance of the interface to which it is connected. Termination is generally not required in lower speed networks (9600 baud or less) and networks shorter than 500m in length. No more than 2 termination resistors should be used, one at each end of the RS485 trans-

mission line. A baud rate of 4800, 9600, 19200, 38400, 56800 or 115200 needs to be selected using the baud rate option. Other settings, including the number of bits, odd or even parity and 1 or 2 stop bits are added in the settings eld. The most common setup is 8 bits, no parity and 1 stop bit or 8N1. The serial interface can be congured in serial capture mode or MODBUS mode using the mode option. Capture mode is typically used where an external sensor sends serial data and a portion of that serial data is to be captured. MODBUS mode is used to connect to external sensors that are compatible with the MODBUS standard. In serial capture mode The device listens for periodic data and when received, transmits this data at the next send interval. The maximum length of a message that can be captured is 512 characters. Once 512 characters have been received, the Senquip QUAD will terminate the capture and will transmit it on the next transmit interval. In capture mode, the max-time setting can be used to set a timeout after which the serial port will return to sleep. Max-time can be used as a way to end serial measurement in the event that no serial data is received, or as a mechanism to allow the device to sample the serial port for a dened time-pe-

riod. Note If the serial port needs to be kept on all the time, set the max-time to longer than the measure-

ment interval. The contents of the serial buer is retained as long as the device does not return to sleep. The operation of the max chars option is similar to the max time setting except that the serial port stops sampling after a certain number of characters has been received. In most cases where the max-chars setting is used to terminate serial capture, the max-time setting is also used to end the serial measure-

ment in the event that data does not arrive. In Serial capture mode, in systems where many messages are sent and only a few are of interest, a start string of up to 10 characters can be enabled. For instance, in a typical GPS serial NMEA feed, the following are a subset of available messages:

DTM - Datum being used. GGA - Fix information GLL - Lat/Lon data GSA - Overall Satellite data GSV - Detailed Satellite data RMC - Recommended minimum data for GPS RTE - Route message VTG - Vector track an Speed over the Ground If in the application, the user is only interested in receiving the GGA message, then a start string can be set to GGA. In that way, any messages starting with DTM, GLL, GSA or other unwanted messages will be discarded. Note If a start string is enabled, the device will stay awake until the string is received or until the max-time is reached. 58 Chapter 6. External Sensors Senquip QUAD User Guide, Release In rmware revisions less than 2, serial start strings are specied as text, with special characters such as carriage return and line feed being specied by their respective escape sequences. A list of allow-

able escape sequences is given below:

\f Form-feed

\n Newline (Line Feed)

\r Carriage Return

\t Horizontal Tab

\v Vertical Tab

\\ Backslash Note Because escape sequences start with a backslash (\), if a capture string contains a backslash, it needs to be escaped and so is represented as a double backslash (\\). In rmware release 2 and above, serial start strings are specied as text, with special characters such as carriage return and line feed being specied by their respective ASCII codes in hexadecimal. A list of example hexadecimal sequences is given below:

\x0C Form-feed

\x0A Newline (Line Feed)

\x0D Carriage Return

\x09 Horizontal Tab

\x0B Vertical Tab

\x08 Backslash The change to the method used to represent special characters has been made to allow for all ASCII characters to be used, and to allow for hexadecimal data to be captured. Note In rmware revisions 2 and lower, special characters are specied as escape characters. In revi-

sions 2 and above, special characters are represented by their ASCII representations in hexadecimal. In some serial protocols, the start of a packet is specied by a preceding period of inactivity on the serial bus. The Idle Time Before Start parameter can be used to specify an idle time, which is exceeded will trigger the serial port to start capturing serial data. Note If the serial port is capturing data and a subsequent idle time occurs, the capture process will restart and captured data will be discarded. A serial capture stop string of up to 10 characters can also be provided. Again using the NMEA exam-

ple, all NMEA messages end with a carriage return and line feed and so the serial capture stop strings in each case will be the same and will be \r\n or \x0D\x0A in revision 2 and above rmware. In most instances, the serial stop strings will be the same for all messages. Note If a start string is specied without a stop string, or the stop string is never encountered, the serial port will capture characters until the max-time or max-chars is reached, the next measurement interval occurs or 256 characters are received. An optional serial request string can be sent, on each measurement interval, to an external device. The purpose of the request sting is to request data from an external sensor or system. The request string can be a maximum of 10 characters and can be entered as text. Special characters like carriage return and line feed can be inserted using escape sequences or their ASCII representations as described earlier in the chapter. 6.2. Serial interface 59 Senquip QUAD User Guide, Release The Senquip QUAD implements the MODBUS communications protocol standard as a master, which enables communication with many slave devices connected to the network. The Senquip QUAD can be congured to periodically request specic data from slave MODBUS devices on the network and transmit that data at specied intervals. Up to fty MODBUS data requests can be congured; these data requests can either be from twenty individual slave devices or multiple requests from the same device. For each of the fty data reads, the slave address, function and register address need to be specied. The slave address will be specied by the manufacturer of the device that is attached to the Senquip QUAD; in some cases, slave devices allow their addresses to be congured. The function species the type of data to be read from the slave device. The Senquip QUAD supports the following types of data reads:

Disabled - the particular MODBUS channel is not used Read Coil - a 1 bit data value Read Discrete - a 1 bit data value Read Holding - a single 16 bit holding register Read Input - a 16 bit input register Read Holding (32 bits, Little Endian register order) - a 32 bit holding register Read Holding (32 bits, Big Endian register order) - a 32 bit holding register Read Input (32 bits, Little Endian register order) - a 32 bit input register Read Input (32 bits, Little Endian register order) - a 32 bit input register Endianness is the order or sequence of bytes of digital data in computer storage and will be specied by the sensor that is being connected to the QUAD. A single MODBUS device may have multiple data values that can be read. The register address speci-

es which data the slave device needs to deliver. In MODBUS mode, calibration can be applied so that the registers read by the Senquip QUAD can be scaled to be in the units of what is being measured. For instance, a register that returns 0 to 255 may represent 0% humidity to 100% humidity. The Senquip QUAD can be calibrated to take a number and to convert it to humidity in % and return that as the measured value. In any system, the sensor and possibly the measured value will be subject to errors that may accumu-

late to reduce accuracy. In a system that uses the Senquip QUAD to measure uid volume in a 100 litre tank using a MODBUS sensor, the sensor may have oset errors such that with zero liquid in the tank, the Senquip QUAD is showing a small volume. The Senquip QUAD and sensor may also not be perfectly linear in that they may not measure 1 litre in exactly the same way when the tank is empty versus when it is full. The tank itself may also not be perfectly manufactured and may, for instance have walls that are not perfectly straight. All of these errors could add together such that the nal system is less accurate than expected. To achieve a more accurate system, a calibration can be performed. In this example, the tank could be calibrated by adding a small amount of liquid, say 10 litres (low Y) and noting the value reported by the Senquip QUAD (low X). Now ll the tank by adding another 99 litres (high y) and note the value being reported by the Senquip QUAD (high X). By lling the high and low X and Y values into the calibration constants associated with analog mode, oset and non-linearity errors can be eradicated, resulting in a much more accurate system. In MODBUS mode, warning and alarm thresholds for can be set for each MODBUS channel. Once enabled, each time a measurement is completed, the returned value will be compared with minimum and maximum warning and alarm thresholds. If a warning or alarm level is breached, a message will immediately be transmitted. As long as the warning or alarm condition persists, messages will be transmitted at the exception-interval rather than the transmit-interval. Note If calibration has been applied, then the warning and enable thresholds are in the calibrated units. A full list of serial interface settings is given in the table at the end of the chapter. 60 Chapter 6. External Sensors Senquip QUAD User Guide, Release 6.3 CAN Bus interface The Senquip QUAD-C1 has a CAN bus interface that can be used to read data from all kinds of vehi-

cles and sensors that use CAN as their communications medium. Hundreds of sensors can be connected to a single CAN network. In many cases, the protocol that is being used on the CAN bus is known, and so large volumes of understandable data can be extracted from all kinds of vehicles. Common CAN protocols include:

J1939, the dominating CAN-based protocol for trucks and busses. ISO 11783, a J1939 avor for agricultural tractors. ISO 11992, an interface between trucks and trailers. NMEA 2000, a protocol based on J1939 for marine use. CANopen, provides a standard for industrial machinery commonly used in industrial automa-

tion. The Senquip QUAD is compatible with the latest CAN Flexible-Data-rate (FD) specication. Pins 11 and 12 on the Senquip QUAD header provide the interface to a CAN network with pin 11 being CAN High (dominant high) and pin 12 being CAN Low (dominant low). In CAN networks, 120 terminating resistors are found at each end of the network. In most systems, the terminating resistors will already be in place and will not be needed. In cases where a sensor network is being formed between an Senquip QUAD and external sensor, a 120 resistor should be placed between the pins 11 and 12 on the Senquip QUAD. Warning In CAN bus systems, the ground supplied to the Senquip QUAD must be the same ground as used by the CAN network. High dierential voltages between the CAN lines and ground can damage the CAN interface. 6.3.1 Specication Specication Parameter 2.9V CAN High driver voltage (typical) 0.9V CAN Low driver voltage (typical) Common mode voltage for reception (maximum)

+-25V Absolute maximum voltage on CAN High and CAN Low +-60V Termination resistor 120 6.3.2 Settings Measurements can be scheduled as a multiple of the base-interval. The fastest possible measurement rate is achieved by setting the interval to 1 in which case the CAN network will be sampled on every base interval. To reduce power consumption, the measurement rate can be turned down by increasing the interval. The Senquip QUAD CAN bus supports can bit rates of 125, 250, 500 and 1000 bits per second as speci-

ed in the Nominal Baud Rate eld. To ensure minimum intrusion on CAN systems, the Senquip QUAD can be set to listen only. In this mode the Senquip QUAD will only receive messages that are acknowledged on the bus by a listening node. Where required, the Senquip QUAD can be made to acknowledge messages by selecting the TX Enable option. A typical automotive CAN network will contain hundreds of messages, all with their own identiers. 6.3. CAN Bus interface 61 Senquip QUAD User Guide, Release The Senquip QUAD can lter only the required messages by lling in the ID Capture List. Required identiers should be entered in hexadecimal and should be separated by commas. When the Senquip QUAD wakes for the next measurement interval, the CAN network will be sampled until all the messages listed have been found or the Capture Time has been reached. If multiple messages with the same identier are required in a single measurement interval, place a * followed by the number of messages of that identier to be returned after the identier in the list. For example: 18FF20F2*4, 18FF36F0, 18FF1BF2*10 will return 18FF20F2 four times, 18FF36F0 once and 18FF1BF2 ten times. Leave the ID Capture List blank to receive all messages. The Capture Time setting can be used to set a timeout after which the CAN bus will stop listening, allowing the Senquip QUAD to transmit received messages and return to sleep. Capture-time can be used as a mechanism to allow the Senquip QUAD to sample the CAN bus for a dened time-period. A full list of CAN bus settings is given in the table at the end of this chapter. 6.4 External Sensor Settings A full list of settings for external sensors is given in the table below.

External Sensor Settings 69 Senquip QUAD User Guide, Release 70 Chapter 6. External Sensors Chapter 7 Scripting Senquip devices have the ability to run user written scripts, allowing extra exibility. The scripting language is called mJS and is essentially a restricted JavaScript engine. Typical uses include:

Scripting on Senquip devices allows:

Decoding and parsing of messages from serial and CAN-bus devices Mathematical manipulation of measured data Controlling connected devices Creating complex alerts that may be dependent on more than one variable Customisation of data payloads to be compatible with third party dashboards Scripts can be executed in response to a measurement cycle completing, a trigger button being pressed, or based on a recurring timer function. For more information about writing JavaScript for a Senquip device, please see the Senquip Scripting Guide. 7.1 Risks Warning The scripting environment is a powerful tool. If incorrectly used the scripting functions may cause the device to malfunction, or even permanently brick the device. The mJS scripting environment provides low level access to the devices memory and CPU. Running a script on the device is not without risk, some of which include:

Permanent lesystem damage rendering the device unable to boot. Malfunction of other functions, such as regular reporting of data to the portal. Memory corruption, causing incorrect reporting of data. Memory leaks, which may present intermittently or after a period of time. Loss of remote control over the device, if your Portal account is compromised. A good understanding of the environment, language and best practices will help avoid or mitigate these risks. 7.2 Access Scripts can be written and securely downloaded to the device from the Senquip Portal. There are several requirements for access scripting on your device:

71 Senquip QUAD User Guide, Release You must have ADMIN status on the Portal for the device. Your Portal account must be granted SCRIPTING permissions. This can be granted by making a request to support@senquip.com Once the requirements are met, you can access the scripting page at: https://portal.senquip.-

com/script/DEVICEID or by pressing the scripting icon on the device dashboard. 7.3 Writing and deploying a script The scripting page on the Senquip Portal allows scripts to be written and downloaded, and custom variables, custom settings, and triggers to be created. Figure 7.1. Senquip scripting page Once written, the user can deploy the script to a remote device by pressing the download button and then the reboot button. To enable error reporting, enable the Send Errors option. If the script termi-

nates unexpectedly, a message will be sent with a description of the reason that the script failed to complete execution. 72 Chapter 7. Scripting Senquip QUAD User Guide, Release Figure 7.2. Feedback on unsuccessful script Scripts can be saved to a le using the Save button on the scripting page. It is recommended that all scripts are backed up to a secondary storage medium. Note Remember to backup your scripts. 7.3. Writing and deploying a script 73 Senquip QUAD User Guide, Release 74 Chapter 7. Scripting Chapter 8 Network Connection The Senquip QUAD can communicate with the Senquip Portal or a remote server via Wi-Fi or 4G LTE. Where both Wi-Fi and 4G LTE networks are selected, the Senquip QUAD will rst attempt to connect via Wi-Fi and if that is unsuccessful, the device will then attempt to connect via 4G LTE. In the event that neither Wi-Fi or 4G LTE networks can be found, the device can be set to log data to internal memory and then upload it when a network becomes available (see Endpoint settings). 8.1 Wi-Fi specication Wi-Fi on the Senquip QUAD is used to transmit data, to allow settings to be remotely updated, to allow in-eld software updates and also to enable setup via an integrated web-server that can be accessed in setup mode via a mobile phone or other Wi-Fi device. The Wi-Fi implementation supports Wi-Fi 802.11 b/g/n. The Wi-Fi antenna is integrated into the Senquip QUAD. In typical applications, the range achievable with Wi-Fi is 500m. 8.2 4G LTE specication 4G LTE on the Senquip QUAD is used to transmit data, to allow settings to be remotely updated and to allow in-eld software updates. The 4G LTE implementation is designed for global use and supports Cat-M1 and NB-IoT in the following bands:

FAKRA-D 4G LTE antenna connector 8.3 Connecting to a Wi-Fi network Once in setup mode, use the Network page to connect the Senquip QUAD to a Wi-Fi network. On the Network page, press the Scan for Wi-Fi Networks button. After a few seconds, a list of SSIDs for visible Wi-Fi networks will be shown. Select the Wi-Fi network to which you would like to connect by selecting the SSID from the list. The SSID will automatically be copied to the Wi-Fi SSID eld and you will be prompted for the network password. After entering the password, press Save Settings. You will be prompted to restart the device; settings will only be applied after a restart. To continue with setup, press CANCEL or to restart and apply your settings, press OK. 76 Chapter 8. Network Connection Senquip QUAD User Guide, Release Figure 8.2. Save changes and reboot After a reboot, the Senquip QUAD will attempt to connect to the specied Wi-Fi network. You can check if the Senquip QUAD has successfully connected to the chosen network by placing the device in setup mode and returning to the Network page. At the top of the page, the current network status will be shown. Note the IP address that your Wi-Fi modem has allocated to the Senquip QUAD; you can use this address to access the device directly on your WiFI network. 8.3. Connecting to a Wi-Fi network 77 Senquip QUAD User Guide, Release Figure 8.3. Note the IP address on your network Further Wi-Fi settings are available by selecting the Advanced option. Once selected, a static IP address, netmask, gateway and DNS server can be specied. The integrated web-server is normally only active in setup mode; it can however be made to be always on by setting the web setting to ON. This may be an advantage in systems where permanent power is available and the user wants to be able to make remote changes directly on the Senquip QUAD without having to access the Senquip Portal. Keeping the web-server active will require that the device remain awake at all times but does mean that the user can make instant changes to settings and see the latest measured data. 78 Chapter 8. Network Connection Senquip QUAD User Guide, Release Figure 8.4. Access via local IP When connected to a Wi-Fi network, the Senquip QUAD may need to be able to make outgoing connections to remote services. To allow the device to make connections, some ports need to be enabled for outgoing connections on your Wi-Fi network. Function Port Number Description NTP Time MQTT to Senquip Portal 123 8883 OTA update 80, 443 8.3.1 Wi-Fi settings To be able to correctly timestamp measured data and for certain encryption functions the Senquip QUAD needs to know time accurately. Time is accessed by connecting to an NTP server on this port. Secure communications with the Senquip Portal are established on this port. Over the Air (OTA) is a method by which the Senquip QUAD software can be remotely updated. To enable remote software upgrades, outgoing connections need to be enabled on this port. A full list of Wi-Fi settings is given in the table at the end of the chapter. 8.4 Connecting to a mobile network Once in setup mode, use the Network page to connect the Senquip QUAD to a mobile network. In most cases only an APN will be required to establish a 4G LTE connection. Some service providers will require a username and password and some SIM cards will require a pin. If these are not needed, leave them blank. For CAT-1 devices, an additional Connection Mode setting is available. This setting allows the selection 8.4.

Network Connection Chapter 9 Endpoint Setup When connected via Wi-Fi or 4G LTE, data measured by a Senquip QUAD can be sent to the Senquip Portal or a remote server or SCADA system, using UDP, HTTP, HTTPS, MQTT and MQTTS. The endpoint settings allow for conguration of the end server detail and the protocol used to communicate with that server. 9.1 Data security Devices that connect to company networks and the internet need to be properly secured to mitigate risks and protect organisations from malicious cyber-attacks. Senquip takes the challenge of cyber-se-

curity seriously and utilises public-key-infrastructure as a part of their security solution to create a unique, trusted and protected identity for every Senquip QUAD. Public Key Infrastructure certicates are an important part of developing a complete security solution. By authenticating devices, encrypting condential data, and maintaining data and system integrity, certicates establish online trust and reliable security. Authentication: Certicates for devices validate identities to make sure only authorized users, messages, or other types of servers have access to the device. Encryption: A certicate creates an encrypted link and allows information to be transmitted privately. Integrity: Certicates make sure that any messages or data transferred to and from Senquip devices are not altered. To ensure the highest levels of each of the three levels of trust, Senquip uses a NIST validated, ultra-secure hardware crypto-element for key and certicate storage and cryptographic processing. The crypto-element is pre-loaded with certicates for Amazon Web Services (AWS), allowing for immediate, out-of-the box, secure communication with the Senquip Portal. Users can load additional certicates to allow secure communications with other servers, using the Senquip Portal. Note For volume applications, Senquip can supply the Senquip QUAD pre-loaded with additional certicates. 9.2 Data format Data that is transmitted by the Senquip QUAD to a remote server is formatted in JSON format. JSON

(JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and it is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. 81 Senquip QUAD User Guide, Release JSON is built on two structures:

A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. An example data JSON packet as sent by a Senquip QUAD is shown below:

Figure 9.1. Example JSON data packet Users of the Senquip Portal do not need to understand the data format; data can be viewed on the Senquip Portal numerically or graphically or can be downloaded in spreadsheet format. For users who are sending data to third party servers that require data in a format other that JSON, arbitrary data formats can be scripted on the Senquip device. Application notes are provided that detail the scripting of custom data packet formats for connection to common third party platforms. Further information on scripting for Senquip devices can be found in the Senquip Scripting Guide. 9.3 Data buer Where neither Wi-Fi or 4G LTE networks can be found, the Senquip QUAD can store up to 10 MB of messages to internal memory for later transmission when a network becomes available. When the internal memory is full, the device stop logging. Once network connectivity is established, the most recently stored data will be transmitted rst. 82 Chapter 9. Endpoint Setup 9.4 UDP Senquip QUAD User Guide, Release Data can be sent via raw UDP to a xed IP address and port. This method is only suitable for a local network Wi-Fi connection as the data is not encrypted and there is no authentication. Raw UDP also provides no acknowledgment that data was received. 9.5 HTTP An HTTP session is a sequence of network request-response transactions. The Senquip QUAD initi-

ates a request by establishing a HTTP connection on a particular port on a client server (typically port 80, occasionally port 8080). 9.6 HTTPS HTTPS is the secure version of HTTP and is sometimes referred to HTTP over TLS. The S at the end of HTTPS stands for Secure. It means all communications between your browser and the website are encrypted. Wherever possible, HTTPS should be used as an alternative to HTTP. HTTPS requires that the certicate-authority (CA) certicate of the destination be loaded onto the Senquip QUAD. Note for volume applications, devices can be pre-congured with CA certicates to allow secure communications with a customer server. 9.7 MQTT MQTT is a secure machine-to-machine (M2M) Internet of Things connectivity protocol specically designed for low data-rate applications and is perfect for implementation on Senquip devices. MQTT is the protocol used when the Senquip QUAD communicates with the Senquip Portal and is also supported by many open source IoT platforms such as Thingsboard. Note Senquip devices can maintain concurrent MQTT connections to the Senquip portal and a customer server or SCADA system. Consideration must be given to data security on open networks. In applications where data security is critical, the use of MQTTS with encryption and authentication should be considered. 9.8 MQTT over TLS MQTT over TLS (MQTTS) adds enhanced security as all data is encrypted and secured with SSL certicates. Most business grade IoT platforms such as AWS (Amazon Web Services) oer MQTTS. MQTTS is recommended by Senquip as the preferred protocol for use with the Senquip QUAD as it oers a low power, reliable, secure connection. The Senquip QUAD is pre-loaded with certicates allowing secure communication with the Senquip Portal. Note For volume applications, devices can be pre-congured with additional certicates to allow secure communications with a customer server or SCADA system. 9.4. UDP 83 Senquip QUAD User Guide, Release 9.9 Settings UDP, TCP and HTTP connections require an IP address of the host server and a port on which the host server is listening. Secure protocols like MQTTS and HTTPS require certicates to be loaded on the device. The Senquip QUAD is pre-loaded with certicates that allow connection to the Senquip Portal that is hosted on Amazon Web Services. Certicates for customer servers can be uploaded using the Senquip Portal. All messages are time-stamped using the UNIX time standard. Unix time (also known as POSIX time or UNIX Epoch time) is a system for describing a point in time, dened as the number of seconds that have elapsed since 00:00:00, Thursday, 1 January 1970. Every day is treated as if it contains exactly 86400 seconds, so leap seconds are not applied. UNIX time is used to timestamp messages as it is used widely in Unix-like and many other operating systems and le formats. The Senquip QUAD automatically updates time by accessing a Network Time Protocol (NTP) server. By default the device will get the time via NTP from pool.ntp.org, on whatever network connection is available (Wi-Fi or 4G LTE). It does this if the time is not valid, for instance, after a reset, and then every 12 hours thereafter. Between updates, time is kept with a high precision real-time clock that is powered by the internal LiPo battery. Although UNIX time is easy for computer systems to use, it is not easily human readable. If a human readable time-stamp is required, set the timestamp setting to ON, in which case, the device will insert an additional time and date eld, formatted in human readable format, as below:

DD/MM/YYYY, hh:mm:ss for example: 27/06/2018, 17:30:15 Time is UTC (coordinated universal time); no osets are applied for local time-zones. The Senquip Portal will apply local time osets as specied by the settings on your computer. The Senquip Portal can be used to update settings on the Senquip QUAD remotely. Each time the device makes contact with the Senquip Portal (for example to transmit measurements), the device will check for any settings changes. If there are changes to settings, these will be downloaded and applied. Pending conguration changes are listed on the settings pages on the Senquip Portal. Figure 9.2. Pending change where the base interval has been changed to 600 seconds If the Senquip QUAD is congured to send data to a 3rd party server, the device will by default contact the Senquip Portal to check for settings updates once a day. Set the Conguration via Senquip Portal to OFF to prevent the device from contacting the Senquip Portal to check for settings. This setting may be used where power consumption is critical such as when AA batteries are being used an a very long battery life is required. Warning Disabling Conguration via Senquip Portal will mean that no settings or rmware updates will be able to be performed remotely using the Senquip Portal.

Endpoint Setup Chapter 10 Senquip Portal The Senquip Portal is Senquips secure cloud solution that is powered by Amazon Web Services

(AWS). The portal allows for:

numerical and graphical viewing of current data, long term data storage, remote modication of settings, remote updates to rmware, event forwarding, user account management. By default, access to the Senquip Portal is enabled; it is highly recommended that users retain this setting. If disabled, device settings may not be able to be changed remotely and important rmware changes will not be able to be performed. Two instances where access to the portal may disabled are in very power battery operated applications and where the device is connected to an alternate server. Warning Disabling communication with the Senquip Portal will mean that no settings or rmware updates will be able to be performed remotely using the Senquip Portal. Connection with the Senquip Portal is achieved using an MQTT connection. To ensure the highest levels data security, Senquip uses a NIST validated, ultra-secure hardware crypto-element for key and certicate storage and cryptographic processing. The crypto-element is pre-loaded with certicates for AWS, allowing for immediate, out-of-the box, secure communication with the Senquip Portal. 10.1 Using the Senquip Portal This section describes the various features of the Senquip Portal and how to use them. 10.1.1 Login to the Senquip Portal The Senquip Portal can be accessed at: https://portal.senquip.com/.

Senquip Portal Senquip QUAD User Guide, Release Note In applications where power is available, a quicker transmit interval will mean that settings changes can be made more quickly. 10.1.7 Remote Firmware Updates Senquip will routinely make rmware updates to enable new features, enhance security and x bugs. Device rmware can be updated via the Senquip Portal. To update the rmware, press the Update button on the settings page. You will be directed to a page asking for the rmware number. This number can be found in the Device Firmware Changelist on the Senquip website or through your preferred distributor. Figure 10.11. Remote rmware updates via the Senquip Portal A Firmware Update typically takes about 5 minutes on Wi-Fi and 20 minutes on 4G LTE. During the update the green light will be o and the orange light will ash fast. Once the device has received the rmware update and is processing it, the lights may appear to freeze. This is normal behaviour. Please allow plenty of time for the device to nish the update and return to normal operation. Note There is always a risk that something may go wrong during a rmware update; it is not recom-

mended that rmware be updated unless it is suggested by Senquip or a specic new feature is required. Note Under some circumstances, output states may change during rmware updates. 10.1.8 Event Reporting The Senquip Portal allows forwarding of alert, warning, and alarm events generated on a device to email or SMS endpoints. A Hosted plan is required for this feature. Use the Events page on the Senquip Portal to congure event reporting. Events can be congured to be sent once as they occur, or with a daily reminder. Warning Make sure to add no-reply@senquip.com to your safe senders list on you email client to prevent email events from going into spam or junk folders. 10.1. Using the Senquip Portal 97 Senquip QUAD User Guide, Release Figure 10.12. Congure event forwarding If an event is current, and the event escalates, for example a warning turns into an alarm, the more severe event will be forwarded. If an event is current and it de-escalates, for an example, an alarm turns into a warning, the event will not be forwarded. If a type of event is current, and a new type of event occurs, the new event will be forwarded. For instance, if a high current warning is active and has been forwarded to email or SMS, and a high temperature warning becomes active, the high temperature warning will also be forwarded. 10.2 Management and Hosting on the Senquip Portal The Senquip Portal oers hosting of data, a data visualisation dashboard, rmware upgrades, and device management including remote conguration and scripting. Every Senquip device purchased comes with a managed plan for the life of the product (10 years). Managed plans allow remote congu-

The only serviceable item is the internal LiPo backup battery. 12.1 Replacing the LiPo Battery It is expected that the LiPo battery will have an in service life of 5 years. Factors that will reduce the life are:

Exposure to temperatures above 55C or below -10C. Unusually high number of charge / discharge cycles. Being left in a discharged state for an extended period of time. Replacement of the LiPo battery should only be performed by suitability trained service personnel. Only LiPo batteries supplied by Senquip should be used. Senquip LiPo batteries contain temperature sensing and protection circuitry to ensure safe operation of the Senquip QUAD. Note Use of 3rd party batteries may cause damage to the unit and will void the warranty. The LiPo battery is located under the user access panel inside the Senquip QUAD. To replace the LiPo battery, the following steps need to be completed:

Un-fasten the 4 hex-head screws securing the cover using a 4mm hex bit. The screws are captive and will not fall out when loose. Do not attempt to remove the screws from the lid. When the lid is opened, an internal light detector will recognise the increase in brightness and will enable the LEDs and conguration switches. 107 Senquip QUAD User Guide, Release Figure 12.1.

Table of Contents 13.2 Senquip Portal 13.2.1 Do I need a hosted subscription to remotely congure my device?

No. The purchase of a Senquip device entitles the owner to make conguration changes, perform rmware updates and view data using the Senquip Portal for the life of the device. 13.2.2 Do I need a hosted subscription to perform rmware updates?

No. The purchase of a Senquip device entitles the owner to perform rmware updates using the Senquip Portal for the life of the device. 13.2.3 Can I view data on the Senquip Portal for free?

Yes, you can view data on the Senquip Portal on a free basic plan. Updates to the Senquip Portal will be limited to 5 minute intervals and the data will not be stored for more than a day. 13.2.4 I cannot see historical raw data on the Senquip Portal. If your device is on a free basic plan, Senquip will not store more than 1 day of historical data. Continuous backups of data storage becomes expensive so is feature of hosted plans where data will be saved for 2 years. Updating a device plan to hosted can be done on the Senquip Portal by using the subscriptions facility. 13.2.5 Do I have to use the Senquip Portal to view my data?

Senquip devices can send measured data to any endpoint via UDP, HTTP, and MQTT. Data transfers can be secured through the upload of customer certicates to the device. 13.2.6 Can I completely disconnect from the Senquip Portal?

Yes. To stop sending data to the Senquip Portal, unselect the Send Data to Senquip Portal option in the endpoint settings. To stop conguration settings from the Senquip Portal unselect Conguration via Senquip Portal. Further settings updates will have to be done using the Senquip webserver. 111 Senquip QUAD User Guide, Release 13.2.7 Does Senquip have access to my data?

No. Unless you give a Senquip employee access to a device by giving them view, operator, user, or admin status, Senquip employees will not be able to view your data. Sometimes, you may give a Senquip employee access to your device so that they can assist you in setup. As an administrator, you can remove this access at any time. 13.2.8 Can I secure proprietary scripts?

Yes. You can use the lock feature on the Senquip Portal to lock scripts so that only you can access the content of the script. 13.2.9 I have added a measurement in the settings, but the widget is not show-

ing in the portal. Browsers typically cache most of the elements in a webpage. Refresh your Chrome or Edge browser by: * Hold down Ctrl and click the Reload button. * Or Hold down Ctrl and press F5. Check that the widget has not been turned o in the portal display settings. To turn on (or o) a widget, press the eye icon on the device page and select which widgets you would like to show, and the order in which you want to show them. Remember to refresh your browser. 13.2.10 There are measurements missing in the data stored on the Senquip Portal. When a Senquip device tries to connect to a network but cannot, it will retry several times and then discard the measured data and return to sleep. If you would like data to be stored when there is no coverage, select the Oline Buer option in endpoint settings. If the transmit interval is dierent to the base interval, the measurement that coincides with the Transmit Interval is the one that will be sent. If you would like the measurements taken on every base interval to be stored, select the Batch Transmit option under general settings. 13.2.11 I have logged into the Senquip Portal but there is no data showing. Measurements will only show on a device page in the Senquip portal once a device has published measurements to the portal at least once. When you receive a new device, it will be in freight mode, and it will not have published data to the Senquip Portal. Power the device to exit freight mode, congure the network settings and the device will start to publish data at the specied Base Interval. 13.2.12 I have changed a setting on the Senquip Portal, but the Senquip device has not changed behaviour. When a setting is changed on the Senquip Portal, it is added to a queue that is stored until the device next makes contact. To see if a setting has been applied by a device, press the command queue button at the top of each settings page. Settings changes shown in green have been applied. For remote conguration using the Senquip Portal to be possible, the Conguration via Senquip Portal option must be selected in the endpoint settings. 13.2.13 I have many Senquip devices and I am struggling to identify them. Once you have many devices installed, it can be dicult to identify which Senquip device is performing which function. It is highly recommended that each device is named using the Device Name setting when rst installed and that devices are added to logical groups on the Senquip Portal. If a device has not been named and it needs to be identied, turn the GPS on to determine its location. The columns on the device summary page can be customised to show key data for a group of assets. You may, for instance want to show fuel level, utilisation and alerts on the summary page. 112 Chapter 13. Frequently Asked Questions Senquip QUAD User Guide, Release 13.2.14 Is my data secure?

Yes. To ensure the highest levels of security, Senquip devices use a NIST validated, ultra-secure hard-

ware crypto element for key and certicate storage and cryptographic processing. The crypto-element is pre-loaded with certicates for Amazon Web Services (AWS), allowing for immediate, out-of-the box, secure communication with the Senquip Portal. Users can load additional certicates to allow secure communications with other endpoints. Data stored on Senquip device is encrypted using AES256 encryption. 13.2.15 Can I use symbols and characters as units on the Senquip Portal?

Yes. To use symbols like the degrees symbol (o) as in oC, create the text in an editor such as Microsoft Word or Notepad and copy it into the eld in the Senquip Portal. Alternatively, use the alt code for the symbol you need, for instance, ALT 0167 for the o symbol. 13.2.16 I cant add a user to a device. To add a user to a device, you must have administrator priveledges for that device. For a user to be added to the Senquip Portal, they must have activated an account on the portal. To add a user, from the device page, press the Users icon in the top right. Enter the email address with which the user has signed up to the Senquip Portal. Select the user permissions as Admin, User and Read. If the email address entered is not associated with an activated account on the Senquip Portal, an error will occur, and the user will not be added. 13.2.17 How do I change the payment details for my subscriptions?

You may want to change your payment method when, for instance, your credit card has expired and you need to add an updated version. To change payment details, login to the Senquip Portal and select the Account option at the top right to navigate to your account page. Select the Billing Detail option and then press the Edit Billing Detail or View Invoices banner. This will take you to the secure payment portal from where you can add payment methods by pressing Add payment method and delete payment methods by pressing the cross next to each payment method. 13.2.18 Where can I nd copies of invoices for subscription payments?

Login to the Senquip Portal and select the Account option at the top right to navigate to your account page. Select the Billing Detail option and then press the Edit Billing Detail or View Invoices banner. This will take you to the secure payment portal where invoice history can be seen at the bottom of the page. Click on an invoice to open the details of that invoice and to download a copy. 13.3 Network 13.3.1 I have inserted a SIM card, but the device is not connecting to the net-

work. Senquip devices that use 4G networks need to be congured with an Access Point Name (APN). The APN is unique to each mobile service provider and should be known by the provider of the SIM. Sometimes a username and password are also needed for a SIM. To congure SIM settings, use the device network settings page. Later versions of rmware for Senquip devices include a feature called Auto-APN. With Auto-APN, the Senquip device reads data o the SIM and searches a database to try and nd a suitable APN. If successful, the Senquip device will connect directly to the network. Senquip produces devices for 4G LTE CAT-M1 and 2G, 3G, 4G CAT-1 networks. CAT-M1 is a newer protocol supported by most networks and deliveres extended range from a given 4G tower. Make sure that the 4G network that you are using supports CAT-M1, sometimes referred to CAT-M. 13.3. Network 113 Senquip QUAD User Guide, Release 13.3.2 What is Auto-APN?

Later versions of rmware for Senquip devices include a feature called Auto-APN. With Auto-APN, the Senquip device reads data o the SIM and searches a database to try and nd a suitable APN. If successful, the Senquip device will connect directly to the network. 13.3.3 My APN is not on the list of Auto-APN options. If you have a SIM card for which Auto-APN does not work, please contact support@senquip.com to have your service provider details added. 13.3.4 Why does Senquip prefer to operate on the 4G LTE CAT-M1 network?

Senquip supports 2G, 3G, 4G, and 5G LTE networks. We prefer to use the 4G and 5G LTE CAT-M1 service where available. 3G networks are being turned-o in many counties including Australia and New Zealand from 2020. 4G and 5G networks are capable of very high-speed data transfer that is not required for IoT devices. The designers of the networks realized this and introduced IoT specic services NB-IoT and CAT-M1. These services use lower power and achieve extended ranges, meaning longer battery life and better coverage in buildings and remote areas. Senquip prefers 4G and 5G CAT-M1 over NB-IoT as the prior has data rates that allow for in-eld updates and the technology allows roaming between towers in mobile applications. 13.3.5 I cannot see my Senquip device on my local Wi-Fi network. If you know a Senquip device IP address on your local Wi-Fi network, then you can login to the device webserver provided it is active. The webserver will only be active in setup mode unless the Web Server option has been selected in general settings. The webserver will be inactive if the Senquip device is sleeping, to prevent the device sleeping, select the Device Always On option in general settings. The webserver will be disabled if 4G communication options have been chosen as it is a signicant security risk to leave the webserver active when operating on an open network. 13.3.6 I am not sure if my Wi-Fi network is reliable enough. Wi-Fi networks can be aected by the number of transceivers, the geometry of the site and the way in which a Senquip device is mounted. To receive information of the quality of the connection made by a Senquip device, enable the Report Network Info option in endpoint settings. You will be able to map network coverage using this feature. 13.3.7 What SIM card should I use?

Senquip devices use a Micro SIM. The SIM can be either 1.8V or 3.3V. The SIM needs to be for an operator that supports either a CAT-1 (-H devices) or CAT-M1 (-G devices) network. For volume applications, Senquip can provide devices with SIM cards that are soldered to the PCB during manufacture. Soldered SIMs are more reliable in high vibration environments. 13.3.8 Why does Senquip not allow the webserver to be on when operating on an LTE network?

When a Senquip device is operating on a public LTE network, it will receive an IP address that is open to the internet. If the webserver is enabled, the device may be exposed to malicious attacks by auto-

mated bots that will try to break the password and gain access to the Senquip device. By turning o the webserver, the risk of attack is eliminated. 13.3.9 I have been using the hotspot on my phone to test Senquip devices and 114 Chapter 13. Frequently Asked Questions Senquip QUAD User Guide, Release it is not working anymore. The Wi-Fi Hotspot feature available on most smartphones is typically limited to between 3 and 5 active device connections. Once this limit is reached, the smartphone will not allow further devices to connect. We note that one some newer smartphones, this limit has been increased to 10. We also note various work arounds to increase this limit. 13.4 GPS / GNSS 13.4.1 Is the Senquip GPS compatible with other GNSS networks?

Yes, the Senquip GPS will receive data from GPS, GLONASS, Bei Dou, Galileo, and QZSS satellites. Senquip uses the term GPS instead of the more correct GNSS because it is more commonly under-

stood. 13.4.2 I have enabled GPS but I am not seeing any GPS data. To provide GPS data such as position, and speed of satellites, Senquip devices needs to connect to satellite constellations. Ensure that the device is mounted in a location where the device has a clear view of the sky, not through metal. Ensure that the device is mounted with the cable gland down. In poor reception areas, the device may require additional time to acquire satellite data. Try increasing the GPS Max Time to 240 or even 360 seconds in poor reception areas. 13.4.3 Can I attach a GPS or 4G antenna to my Senquip Senquip device?

No. The Senquip Senquip device has all required antennas internal to the device. This has been done specically as Senquip Senquip devices are expected to be used in harsh conditions where antennas would be damaged. If you need an external antenna, please use a Senquip QUAD. 13.4.4 How accurate is the GPS on my Senquip device?

With a clear view of the sky, the position accuracy of the GPS is better than 2.5m 50% of the time, and better than 5m 95% of the time. GPS position accuracy depends on many factors such as the mounting position, orientation, visibility of the sky, weather conditions and time of day. The best position accuracy will always be obtained when the Senquip device is mounted vertically in a position where it has a clear view of the sky. To enhance GPS position accuracy, the Senquip devices track GPS, GLONASS, Bei Dou, Galileo and QZSS satellites. 13.5 Power 13.5.1 Do I need to add AA batteries as a backup in a solar installation?

No. Senquip devices have an internal LiPo battery which, in most solar applications, will be sucient to power the device during the night and in low sunlight conditions. In low power congurations, the internal LiPo battery can power a Senquip device for months. Use the battery calculator on the Senquip website to estimate how long the internal battery will power your solar setup. Senquip devices report the internal LiPo battery voltage. It is recommended that the LiPo battery be monitored for a while after a solar install to ensure it is being suciently charged by the solar panel. AA batteries are only required in applications where there is no permanent or solar power available. They can be added as an additional backup when using permanent or solar power. 13.4. GPS / GNSS 115 Senquip QUAD User Guide, Release 13.5.2 I am running on solar and am losing data at night and on cloudy days. It is likely that your solar panel is not supplying enough energy to power your application and charge the Senquip device internal LiPo battery. Monitor the LiPo battery voltage on the Senquip Portal. A charged battery will reach approximately 4.2V. A low battery is below 3.5V. The simplest way to extend battery life is to increase the Base Interval in general settings. 13.5.3 How can I extend battery life on my Senquip device?

A Senquip Senquip device should be able to last for many years running on AA batteries. To estimate the life of your device, see the battery calculator on the Senquip website. For low power installations such as solar and battery installs, to save energy, consider the following:

Increase your Base Interval. In applications where measured data is not changing quickly, you may be able to increase the base interval. A longer base interval means that the Senquip device spends more time sleeping between measurement intervals and so saves energy. Increase your Transmit Interval. In some applications you may not need every measurement that is taken to be reported but are more interested in receiving an alert when a warning or alarm condition occurs. In these cases, increase the transmit interval so that data is not trans-

mitted on every measurement interval. Once a day measurement may be enough. Turn o peripherals that are not needed. If you are not using the serial port, GPS or other peripheral, make sure that they are turned o. Reduce the interval of peripherals. A Senquip device mounted on a pole is unlikely to move. One GPS update a day may be sucient. The GPS, serial and current sources are the most power-hungry peripherals, use them sparingly. Consider using voltage sensors instead of current sensors. Sensors like liquid level sensors are often available in current or voltage versions. A 4-20mA sensor will draw 20mA at full scale whereas a voltage version may only draw 1mA. Where using the serial and current sensors, reduce the wait times before measurement and before returning to sleep. Make sure that the device is not always on, and that the webserver is o. Under endpoint settings, do not send human readable time and network info. The smaller the set of data you send, the lower the power of your device. Send to a single endpoint if possi-

ble. Senquip is constantly working on code improvements to reduce the power of devices. Make sure that your device is running the most recent rmware version. 13.5.4 I wired my Senquip device incorrectly; have I damaged it?

Senquip devices have protection against the most common wiring faults like reversing the voltage. There are some inputs such as the serial, current sense and thermocouple inputs that can be damaged if connected to supply voltages. 13.5.5 Do I need a fuse in-line with the power supply of my Senquip device?

It is always a good idea to include a fuse in the supply to any electronic device. A 1A fuse would be a suitable size for use with the Senquip device. 13.5.6 I have opened my Senquip device, and the lights are not on. Your device is most likely sleeping; this is good as it conserves power. The lights will come on when the device next wakes for a measurement cycle. If you want to access the device immediately, press the setup button to access the device webserver or press reset to initiate a re-start that will trigger a measurement cycle. If you want to be able to access your device to make settings changes at any time, select the Always On option in the general settings. 116 Chapter 13. Frequently Asked Questions Senquip QUAD User Guide, Release 13.5.7 The device that I am setting up via the webserver keeps switching o. The device webserver is activated by pressing the setup button and then connecting to the device Wi-Fi. The device will exit the webserver when settings are saved and it executes a reset, when the lid is closed or when no activity is detected for a few minutes. To ensure that the webserver does not close-down when you are conguring a device, make sure that you do not cover the device light sensor and that you are not inactive for extended periods of time. 13.5.8 Can I use AA NiCd batteries in my Senquip Senquip device?

NiCd batteries are generally rated at 1.2V. Although the Senquip device will operate from 1.2V batter-

ies, they will not last very long. It is recommended to use high quality Alkaline or Lithium batteries. For longest life, use 1.6V or 3.6V lithium batteries. 13.5.9 Can I use 3.6V lithium batteries in my Senquip Senquip device?

Yes. 3.6V Lithium Thionyl Chloride batteries are generally the longest lasting when used with a Senquip Senquip device. The improvement in life is however small when compared with lower cost Lithium Energizer and other brand batteries that are widely available. 13.5.10 How long will the internal LiPo battery in the Senquip device last?

The lithium battery is expected to last 5 years without signicant degradation. The life of the battery may be reduced if it is exposed to temperatures above 55C or below -10C, if it experienced an unusually high number of charge/discharge cycles or if it is left in a discharged state for an extended time. Spare LiPo batteries can be sourced from Senquip and can be replaced by a quali-

ed technician. 13.5.11 I have received my Senquip device, pressed the setup button and noth-

ing happens. When Senquip devices are shipped, they are placed in freight-mode to preserve the internal battery and to prevent the device from transmitting when being transported. To exit shipping mode, apply power or insert batteries. 13.5.12 How long can I run my Senquip device o AA batteries?

To achieve maximum life, use high quality Lithium batteries such as Ultimate Lithium from Energiser. Battery life will depend entirely on your application, the rate of measurement, transmissions and the types of sensors attached. As a guide, if your Senquip device was to be left sleeping, it could achieve up to 10 years of life. In a typical battery powered application, where the Senquip device is communicating over GSM, with once per hour updates, the Senquip device can be expected to last 2 years on a set of batteries. The Senquip device can be congured to monitor its batteries and report low battery conditions. Use the battery calculator available on the Senquip Portal to estimate the battery life of your system. 13.5.13 Why is my AA battery voltage reading lower than I expect?

If you have inserted four 1.5V AA batteries into your Senquip Senquip device, you would expect the battery voltage shown on the portal to be 6V. It may sometimes instead show 5.5V. There is internal resistance in your battery so that when current is drawn from it, the measured voltage drops. If, for instance, the Senquip Senquip device was drawing energy from the AA batteries to charge the internal battery when a measurement was made, the measured battery voltage would be slightly lower than 6V. There is also a small amount of protection circuitry between the battery and the measurement circuit and again, we would expect a small drop across this circuitry. 13.5. Power 117 Senquip QUAD User Guide, Release 13.5.14 I haven not used my device for a while, and it is taking a long time to make a rst connection. If you leave a device unpowered for an extended time and you have set the Senquip device in a high-power mode by for instance setting a fast update rate, the internal LiPo battery will have run at. When the Senquip device rst receives power, it evaluates the internal LiPo battery and if it is found to be extremely at, the Senquip device will pre-condition the LiPo before resuming normal operation. If you open the lid during pre-conditioning, you will see the green light pulsing slowly during pre-conditioning. 13.5.15 How do I make a Senquip device safe for shipping?

Put the device in freight mode. In freight mode, the battery drain is reduced to almost zero and all transmitters are turned o. Enable freight mode via the webserver, on the Senquip Portal in the Admin page, or from setup mode by pressing the setup button 3 times. The device will exit freight mode when power is applied or batteries are inserted. 13.6 Setup 13.6.1 If I perform a factory reset, will I lose my settings?

Yes. A factory reset will remove all your settings including your network settings. After performing a factory reset, you will need to connect to the device via the internal webserver to re-establish an internet connection. 13.6.2 I performed a factory reset and I cannot remember a setting. Go to the settings page for the device and open the command queue at the top of the page. You will be able to see a log of previous settings applied to the device. 13.6.3 If I perform a rmware update, will I lose my settings?

No. Performing a rmware update preserves your settings. If the rmware update introduces new settings, these will be set to the default value. Note that updates to major rmware revisions may reset some variables such as non-volatile variables used in scripts and hour meters. 13.6.4 Can I save my settings to a le?

Yes. You can export your settings, scripts and Senquip Portal settings to a le using the export settings option in the admin settings. Before exporting your settings, you will need to use the Request Device Settings option to get the latest settings from the Senquip device. 13.6.5 Can I save settings to another device?

Yes. Use the Import Settings option in the admin settings to import settings from another device. 13.6.6 I have lost my password, what can I do?

If you have lost the original device password, please contact support@senquip.com who will assist you in recovery. If your device is connected to your Senquip Portal account, you can continue to view device data and make conguration changes. If you have changed your password, and have forgotten your new pass-

word, a factory reset will restore the original device password. 118 Chapter 13. Frequently Asked Questions Senquip QUAD User Guide, Release 13.6.7 How long does a rmware update take?

The time taken to perform a software update depends on the network type chosen and the signal strength of the connection. A typical update over Wi-Fi will take 5 minutes and an LTE update will take 15 minutes. The orange light will ash during the update process. If the upload is interrupted, it will need to be restarted. A failed rmware upgrade will not harm the Senquip device. 13.6.8 If a rmware update fails, will my Senquip device be harmed?

No. If a rmware update fails, your Senquip device will not be harmed. The Firmware update will need to be restarted. 13.6.9 My device is not accepting a rmware update. In some instances with short base intervals and lots of data being transmitted, the Senquip device may not have the capacity to process a rmware update. In this instance, reduce the base interval to 60 seconds and then apply the rmware update. Once complete and with the device reporting the new rmware version, change the base interval back to the required rate. 13.6.10 How can I force a Senquip device to accept a change made on the Por-

tal if it is sleeping?

Since the device will not contact the Senquip Portal during sleep, no changes can be made until the next transmit interval. To force a device to make immediate contact, press the reset button. After reset, contact is made with the Senquip Portal, and any outstanding settings will load. This is most useful when you have set a long sleep period and want to test a quick change before deployment. 13.7 Operation 13.7.1 Is the time on my Senquip device accurate?

Yes. At boot, the Senquip devices connects to an available network and queries time from an NTP server such as Google NTP. If an NTP server is not available, the device will try to retrieve time from the LTE network and failing that, from the device GPS. 13.7.2 How often is time synchronised on a Senquip device?

Senquip devices renew their time sync every 6 hours. Time between refresh is maintained by a crystal derived source in the device. 13.7.3 Why does the rst measurement after a reset take longer?

After a reset, a Senquip device needs to load the operating system into memory, congure itself and load user settings. This can take a few seconds. 13.8 Scripting 13.8.1 Does my script run in the Senquip Portal?

No. Your script will run on the Senquip device in eld. This means that your script will continue to execute even if your device loses contact with the network. 13.8.2 How do I get access to scripting?

To request access to scripting, please send a message, using the email address associated with your 13.7. Operation 119 Senquip QUAD User Guide, Release Senquip Portal account to support@senquip.com. 13.8.3 I cannot see the scripting icon on the device page. To request access to scripting, please send a message, using the email address associated with your Senquip Portal account to support@senquip.com. 13.8.4 How can I tell if there is an error in my script?

Limited error detection is available real-time in the scripting page. For feedback on why a script that looks ok in the editor has failed, turn on Send Errors in the scripting window. Errors will show up as script events in the events widget on the device page. 13.8.5 My script looks ok in the editor but is failing to run. The most common source of problems with scripts is the use of JSON keys that do not exist. If, for instance, GPS speed is used in a script, but the GPS loses satellite lock, the GPS speed key will no longer be available. When the script tries to use GPS speed, the script fails. Use a function like if

((typeof obj.analog1 === number) to check that a variable exists and is of the correct type before using it. 13.8.6 If my script fails, with my Senquip device fail?

Maybe. In general, if a script fails to end correctly, the script will terminate, and the device will continue to run. Scripting is an advanced feature, and an incorrectly written script can cause a Senquip device to fail or even brick a device. Read the scripting guide carefully before committing a script. 13.8.7 My script looks ok, but I get a calling non-callable error. Your script may be trying to use a function that is not available in the version of rmware that you are using. Update to the latest rmware version before using scripting. 120 Chapter 13.
