    The standard 800mAh LiPo backup battery allows the G100 to operate when external power is removed for up to 4 days, depending on the amount of movement. Optional HUGE battery pack of 1800mAh available on special order.

    5 x Digital Inputs

    • 1 x Ignition line
    • 4 x Digital Inputs with configurable pull-up / pull-down
    • Numerous configuration options including switches, duress/panic alerts, pulse counting.

    2 x Digital Outputs

    2 x switched ground digital outputs, easily wired up to switch external lights, relays, buzzers, sirens, motors and other devices. Can be used to immobilise a vehicle

    Internal Buzzer

    Audible alert without requiring the installation of an external buzzer. Can be used for speeding alerts, harsh driving alerts, reminders to swipe RFID tags, error conditions and other events.

    Diagnostic LED

    The diagnostic LED makes it easy to see if the device is operating correctly.

    3 Axis Accelerometer

    The 3 axis accelerometer allows the G100 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 G100 to go to ‘sleep’ when not moving, resulting in extremely low standby current.


    Communicate with common one-wire iButton devices.


    RS232 receive and transmit allow the G100 to communicate with external RS232 devices. These can include fuel monitoring, Garmin FMI, tyre pressure monitoring. The RS232 interface can also be used to configure the device and to test and debug.

    Switched 5V Out

    The G100 can provide power to external peripherals via this 5V power line, allowing for easy installation and doing away with the need for additional external power supplies.

    Maximum current: 300mA

    DMCAN Peripheral Port

    Digital Matter has a range of peripherals that connect to the G100 via the DMCAN peripheral port. Peripherals such as the RFID Driver ID reader, 5 digit keypad, data console and RF gateway use the DMCAN port.

    Flash Memory

    The G100 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.

    FlexiCard Expansion Slot

    The G100 has one FlexiCard slot. This card slot allows the device to be upgraded to support extra functionality:

    • Iridium satellite modem
    • SDI12
    • RS485
    • Additional RS232 ports
    • Digital Matter can design custom cards by request

    The innovation of FlexiCards allows the G100 to be the most flexible telematics device available on the market.

    6 x FlexiCard IO

    The FlexiCard slot is connected to 6 pins on the G100 connector. This allows the cards to provide functionality to the outside world via the connector pins.

    Peripheral Options

    RFID Driver ID Reader

    Compact 125kHZ RFID Reader reads cards and keyfobs

    • 5cm typical read range (can read through plastic / dashboard)
    • Plugs into the peripheral plug on the G100 harness for easy installation
    • Includes a LED and buzzer for reminding drivers to swipe their card
    • Compatible with the EM4001 RFID standard
    • Optional 125kHz HID reader option

  • Firmware Smarts


    Auto-APN allows the G100 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 G100 can be shipped world-wide without requiring specialist setup for SIMs.

    Text Message Setup

    The G100 can also be sent text messages to setup the APN, server and other details.


    The G100 can be configured to roam across multiple networks and to automatically use the different APN details for the roaming networks.

    AssistNow Offline

    The G100 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 G100 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
    • On Stationary
    • Accelerometer events (harsh driving)

    Accident and Rollover Detection

    The G100 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 G100 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 G100 along with additional event statistics that allow back-end server platforms to perform sophisticated driver profiling and scoring.

    Accident Data

    The G100 keeps a second-by-second “blackbox” 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 G100 supports a number of ways to identify a driver:

    • RFID reader and a card or keyfob
    • 5 digit keypad to enter a PIN code
    • Console with built-in RFID reader
    • iButton 1-wire reader

    Driver Lists

    The G100 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 G100 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 G100 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 G100 has the capacity to hold hundreds of geo-fences that can be downloaded to it from the server. The G100 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 G100 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 G100 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 G100 to monitor the system voltage and to detect changes in the voltage that indicate if the engine is running or not.
