    Low-profile IP67 rugged housing

    The IP67 rated housing is made of sturdy ABS/Polycarbonate plastic to survive bumps and knocks and to survive many years in the sun and weather. It is low-profile and caters for a number of cable glands to allow for waterproof cable entry to the housing. The housing screws together for easy assembly, and has convenient mounting tabs.


    Dimensions

    L 183 x W 145 x H 40mm


    Operating Temperature

    -20°C to +65°C.
    For operation in extreme temperatures, the device must be fitted with Lithium Batteries.


    Power

    Input Voltage

    4.5 - 16V
    4 x C Cell Battery holder fitted and screw terminals for line power.
    Flexible options - from "off the shelf" Alkaline to LiSO2 and 12V options.


    Long-Life

    The Eagle is ultra-low power and can run off a set of batteries for many years, including powering sensors. External power can be used if available.


    External Power Input

    4.5V – 16V
    The internal battery can be used as a backup to operate when external power fails or is not present.
    Fit both 4 x C Cell batteries and connect to line power. If there is a power cut the batteries will power the device.


    Battery Meter

    The innovative battery meter gives an accurate reading of the energy being used from the battery, allowing for superior battery life prediction and monitoring.


    Connectivity

    Cellular Networks

    The Eagle is available in 2 versions.

    2G: SARA-G350-02S-01: 850/900/1800/1900 MHz

    4G LTE Cat-M1 and NB-IoT:
    uBlox SARA-R410M Modem operates on all major global LTE-Cat-M1 and NB-IoT bands.
    Supported LTE bands:
    1*, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26*, 28 (*roaming bands)


    SIM Card

    Hinged Micro-SIM Holder (3FF)


    Antenna

    The Eagle has a U.FL connector on the PCB that connects to an internal cellular antenna by default. This offers the option of installing an external antenna if maximum range is required.

    Configuration

    Firmware and parameters can be changed Over-The-Air (OTA) using Digital Matter’s device management platform “OEM Server”

    GPS Tracking

    GPS/GLONASS Tracking

    - UBLOX EVA-M8Q GPS Module
    - Low-noise amplifier (LNA)
    The GPS design allows the Eagle to operate as a high performance tracking device or to obtain occasional position and time updates


    GPS Antenna

    High Performance internal patch antenna


    Offline Assist

    Offline Assist GPS satellite data is downloaded via the cellular network and stored in flash memory – used to dramatically improve the TTFF (time to first fix) and performance of the GPS


    Interfaces

    SDI-12

    This interface is commonly used in agricultural sensors and measurement devices for soil moisture probes, temperature, electrical conductivity (EC) of soils, water levels / pressures, other SDI-12 probes and sensors


    Switched Sensor Power (Vout)

    Used to control the battery power to external sensors and peripherals. Load limited and short circuit protected.  Output voltage is the same as input voltage.


    I2C Interface

    I2C (inter-IC communications) is an interface commonly used in sensor modules. This allows the Eagle to talk to a wide range of sensors including: temperature, humidity, vibration, CO2 gas and many others. (requires firmware support - contact Digital Matter about sensor support)


    3.3V Switched Power

    Used to control the 3.3V power to external sensors and peripherals. Load limited and short circuit protected.


    3 x Digital Inputs

    Configurable for Pull-up/Pull-Down
    Wake-up from deep sleep
    Can be used for low power pulse counting
    Max input voltage 48V
    Thresholds: ‘Low’ below 1.0V, ‘High’ above 2.6V (approx.)


    2 x Analogue Inputs

    Input range 0-30V with Auto Ranging
    12-bit ADC
    0-5V Range: 1.22mV precision
    0-30V Range: 7.32mV precision


    2 x Digital Outputs

    The switched ground outputs can be used to control external devices and circuits, for example to turn a lighting tower on/off


    2 x 4-20mA inputs

    The 4-20mA inputs can be used to interface to current loop sensors. 0.025mA precision.


    RS-485

    The RS-485 interface can be used to interface to devices that support this interface, including MODBUS.
    This is catered for in hardware and will require specific firmware integration.


    1-wire

    1-wire or "i-Button" can be used to read Dallas tags, or interface to sensors using the 1-wire interface.


    Bluetooth 5

    The Bluetooth Low Energy v5 module can be used to interface to BLE sensors and peripherals, or can be used to scan for BLE tags. This is an exciting new option and adds massive flexibility to the device.
    (may require specific firmware integration)


    Other

    Accelerometer

    3D accelerometer to detect movement.


    Flash Memory

    The flash memory is used to store non-volatile information like parameters and data records. The flash memory is large enough to store approx. 30,000 records.


    Test Button & LED

    Easy do do in-field testing.

  • SDI-12

    The SDI-12 interface is commonly used by agricultural (Ag-Tech) sensors such as soil moisture probes.

    I2C

    The Eagle's I2C interface, along with it's digital and analog inputs allow for a variety of sensors to be connected such as:

    • Temperature/Humidity Sensors

    • Tank Level Sensors

    • Switches to monitor door open/close

    • Panic Buttons


    4-20mA

    Documents and Product Support

  • Device Management – OEM Server


    All Digital Matter devices are fully managed Over-The-Air (OTA) via our OEM Server web interface. The OEM Server seamlessly manages:

    • Device firmware – firmware updates can be done remotely
    • Network (administrator) parameters relating to critical communications
    • System parameters, including GPS parameters, IO configuration, logging options and general device behaviour settings
    • GPS AssistNow Offline aiding data files
    • Remote debugging of devices, including being able to trace data, view detailed debug message logs, and view a live trace of the server debug messages
    • Remote disconnect and reboot of devices
    • Driver list downloads to devices – this allows for the Driver Identification on the device to check if the RFID tag / username / PIN is valid, and for specific drivers to be allowed to drive / operate particular vehicles, for example based on licences or permits.
    • Geo-fence syncing with the devices – this allows the device to do advanced in-cab alerting and monitoring such as geo-fence arrival and departure, speed limit alerting, dangerous intersection warnings, turn on warning lights inside a geo-fence, and disable communications inside intrinsically safe zones such as gas plants.
    • Provides a command and message queueing platform to the devices and is incorporated into the remote management and debugging applications
     

    Data Connectors


    The OEM Server provides Data Connectors that forward data records on to the software platform of your choice, including Digital Matter’s own Telematics Guru platform.
