    Sleep Current:

    The Dart passes stringent automotive power “load dump” tests to ensure that it will continue to operate in the harshest electrical systems. A built-in self-resetting fuse makes installation easy and safe.

    Operating Temperature

    On External Power
    -20°C to +60°C

    Below 0°C the standard internal backup battery’s ability to deliver sufficient power to operate the cellular modem is reduced. Below 0°C and above +45°C the internal backup battery will not be charged as a safety precaution due to dangers associated with charging batteries at extreme temperatures.

    Concurrent GPS and GLONASS Tracking

    • Concurrent GPS and GLONASS tracking
    • 72 channel high sensitivity receiver
    • -169dBm industry leading tracking performance
    • Battery backed up for optimal hot-start performance
    • AssistNow Offline aiding data for extremely fast time-to-first-fix and performance in urban canyon environments

    Low Noise GPS Amplifier (LNA)

    The Dart’s GPS signals are boosted by a special low-noise amplifier (LNA). This allows the Dart to operate where normal units will fail to receive GPS signal.

    Even when designing a low-cost device Digital Matter is not prepared to compromise on the performance of the product. You will see the difference if you compare device performance in low signal environments.

    Internal Antenna

    Internal GPS and cellular antennas.

    Having the antennas inside the housing makes for very simple and quick installation. The Dart has had its antennae tuned by the top laboratories to ensure optimal performance.

    Backup Battery

    The LiPo backup battery allows the Dart to continue to operate when external power is removed for up to 5 days, depending on the amount of movement

    3 x Digital Inputs

    1 x Ignition line
    2 x digital inputs with configurable pull-up / pull-down
    Numerous configuration options including switches, duress/panic alerts, pulse counting and other applications

    1 x Digital Output

    1 x switched ground digital output, easily wired up to switch external lights, relays, buzzers, sirens, motors and other devices. The output can be used to immobilise a vehicle.

    3 Axis Accelerometer

    The 3 axis accelerometer allows the Dart to detect harsh driving events (harsh acceleration, braking and cornering) and this information can be used to monitor driver behaviour and unsafe driving. It also allows the Dart to go to ‘sleep’ when not moving, resulting in extremely low standby current.

    Serial Port

    The TTL serial interface allows the Dart to interface with external devices and peripherals, including a low-cost RFID tag reader for driver identification.

    Switched Power Out

    The Dart can provide power to external sensors and devices via this power line, allowing for easy installation and doing away with the need for additional external power supplies.

    Voltage: 3.5v to 4.5v
    Maximum current: 200mA

    Flash Memory

    The Dart has sufficient memory to store over 50,000 records in its flash memory. Normally the data will be sent to the server immediately but if the device is out of range then there is sufficient space to ensure that no data is lost – for many weeks of driving!

    The flash memory is also used to store parameters, GPS aiding data, accident data, driver lists, geo-fences and other important information that needs to be securely stored.

    Peripheral Options

    Dart RFID Driver ID Reader

    Compact 125kHZ RFID Reader reads cards and keyfobs

    • 5cm typical read range (can read through plastic / dashboard)
    • Includes a LED and buzzer for reminding drivers to swipe their card
    • Plugs into the Molex connector on the Dart harness
    • Compatible with the EM4001 RFID standard
    • Optional 125kHz HID reader option
    • Keyfobs available
  • Firmware Smarts


    Auto-APN allows the Dart to analyse the SIM card and select the correct APN details from a list that is pre-loaded in the device’s firmware. This means that the Dart can be shipped world-wide without requiring specialist setup for SIMs.

    Text Message Setup

    The Dart can also be sent text messages to setup the APN, server and other details.


    The Dart can be configured to roam across multiple networks and to automatically use the different APN details for the roaming networks.

    AssistNow Offline

    The Dart will track successfully where other devices just give up.

    This fantastic technology allows the GPS to predict which satellites are in orbit above it and to dramatically reduce the time-to-first-fix of the GPS, and the overall performance of the GPS, especially in ‘urban canyon’ or forested environments.

    Flexible Logging Parameters

    The Dart trip logging is flexible and can be configured to log based on a variety of parameters including:

    • Elapsed time
    • Distance travelled
    • Change in heading
    • Change in speed
    • When stationary
    • Accelerometer events (harsh driving)

    Accident and Rollover Detection

    The Dart uses the built-in accelerometer to detect high G impacts such as accidents and rollovers and reports these events to the server for emergency alerting.

    Harsh Driving

    The Dart automatically calibrates its built-in 3 axis accelerometer and uses this to detect harsh driving events:

    • Excessive acceleration
    • Harsh braking
    • Cornering at speed

    These events are logged in the Dart along with additional event statistics that allow back-end server platforms to perform sophisticated driver profiling and scoring.

    Accident Data

    The Dart keeps a second-by-second “black box” recording of valuable GPS and accelerometer data for a two hour window. This data can be automatically uploaded to the server when an accident is detected, or it can be requested manually.

    Driver Identification

    The Dart supports a low-cost external RFID reader to read cards and keyfobs in order to identify drivers.

    Driver Lists

    The Dart can be updated from the server with lists of Drivers that are allowed to drive the vehicle that it is installed in. When a driver or operator registers on the Dart it will check the Driver List to see if that person is authorised to drive the vehicle. The list also includes information about the driver such as whether they can perform supervisor functions.

    The Dart can be installed to immobilise a vehicle and only allow authorised drivers / operators to drive it, or to annoy an unauthorised driver with a loud buzzer.


    The Dart has the capacity to hold hundreds of geo-fences that can be downloaded to it from the server. The Dart can use this geo-fence information to:

    • Implement arrival and departure alerts
    • Implement speeding zones with audible warning alerts
    • Implement “No-go” and “Keep-out” areas
    • Automatically control outputs, for example to switch on warning lights when inside a special area
    • Warn drivers when approaching dangerous intersections
    • Disable data communications within intrinsically safe areas

    Emulated Ignition

    This setting allows the Dart to determine that a trip has started based on accelerometer and GPS data and to automatically set the ‘ignition’ input on the device to emulate the ignition line.

    This means that the Dart can be installed with the option of not wiring in the ignition line and ‘emulating’ the ignition based on movement.

    Run Detect

    This setting allows the Dart to monitor the system voltage and to detect changes in the voltage that indicate if the engine is running or not.
