Product Details

Product Overview

3G/GSM module

3G/GSM module

It makes this device usable worldwide, as there are countries which have only 3G network. Device automatically selects available network (3G or 2G) to ensure the best connectivity in area.

Internal high gain antennas


Internal GNSS and 3G antennas make installation easier and faster. Install more units in less time. Internal antennas deliver higher security against possible third party impact.

CAN adapters support

Various vehicle CAN data

Additional accessories LV-CAN200, ALLCAN300 allow you to acquire CAN data from any kind of transport such as light vehicles, trucks, buses, agriculture transport, and special transport. Supported vehicles list contains more than 1800 models. Each vehicle model has particular instruction for installation with scheme and picture. Available parameters: RPM, Total fuel, Fuel level, Vehicle mileage and more.



1-Wire® protocol support enables you to identify up to 500 authorized drivers and connect temperature sensor. iButton® or RFID® allows to prevent unauthorized access to your fleet. Temperature sensors gives you possibility to monitor and control your cargo.

Internal battery


Feel safe when vehicle is monitored by device with internal battery. When external power is disconnected, device still remains online and sends data to server plus provides notification of disconnection.

Trip detection

Trip detection

Easy trip start and stop detection gives you possibility to have the report with correct time, location and driven distance for each trip.

Product Features


  • 3G : 3G is the third generation of wireless mobile telecommunications technology.
  • GNSS : Global positiong system/Global Navigation Satellite System.
  • GPRS : General Packet Radio Service (GPRS) is a packet oriented mobile data service based on the 2G technology.
  • SMS : Short Message Service (SMS) is a text messaging service component.


  • Internal GSM antenna : An antenna used for GSM connectivity. Integrated into MDF device PCB. Does not have external connector.
  • Internal GNSS antenna : An antenna used for GPS connectivity. Integrated into MDF device PCB. Does not have external connector.
  • DIN - digital input - 4 : Digital Inputs allow device to detect logic states 1 (enabled) or 0 (disabled).
  • AIN - analog input - 1: An analog input converts a voltage level into a digital value that can be stored and processed in device.
  • DOUT - 2 : Digital Outputs allow device to output logic states 1 (makes a circuit) and 0 (cuts the circuit).
  • 1-Wire® - 1: 1-Wire® is a device communications bus system that provides low-speed data, signaling, and power over a single conductor.
  • Accelerometer : Accelerometer allows the device to indicate if vehicle is moving or not, as well as measure acceleration.
  • Battery - 170mAh Li-ion 3,7V : Allows device to work without external power source.
  • IP41 : Protected from tools and small wires, condensation.
  • 1MB memory : Internal memory for records storing when there is no GPRS connectivity.
  • 10 - 30V : External voltage range.
  • Overvoltage protection : Protects device from voltage jumps till 90V.
  • 1x SIM Card : Allows to put 1 SIM card for internet connection
  • USB 2.0 Interface : Device accessible and configurable via USB.


  • LV-CAN support : LV-CAN200 is used to listen data from light vehicles. With this adapter MDF device is able to collect and send such data.
  • ALL-CAN support : ALL-CAN300 is used to listen data from any type of transport: light vehicles, Trucks, busses, agriculture and other special transport. With this adapter MDF device is able to collect and send such data.
  • Ignition detection : A vehicle ignition detection function, based on a configured ignition source (External power voltage, Digital input 1 or Movement).
  • Geo-fence : A functionality, which generates an event when crossing a defined area. It can be used to detect wherever car enters or leaves customized areas
  • Sleep/Deep sleep : Working modes which let MDF deviceto reduce power consumption and save vehicle battery.
    - In sleep mode, MDF device turns GNSS module off and it is not saving or sending new periodic data records.
    - In deep sleep mode, MDF devicesets GNSS receiver to sleep mode and turns off GSM/GPRS module, although periodic records with last known coordinate are being saved and sent to server.
  • Overspeeding detection: This scenario helps to prevent from exceeding fixed speed and inspects driver if needed. Digital output 1 is controlled by scenario for user needs, to manage buzzer, LED etc. During overspeeding event Digital output 1 will be turning ON and OFF until speed is lower than configured Max Allowed Speed.
  • FOTA : Firmware over the air solution. The software is used to send firmware/configuration to MDF devicevia GPRS network.
  • Remote Log : This type of MDF data logging is used when there is no possibility to connect to device physically. Device establishes GPRS connection and activates link to server, log is started to stream to server until set time is elapsed.
  • GPRS commands : It is possible to send commands to MDF deviceusing GPRS. GPRS commands can be used for sending configuration, debug, digital outputs control commands etc. These commands should be coded into a special codec12 format.
  • RFID 1-Wire® : Radio-frequency identification (RFID) is the use of a wireless non-contact system to transfer data from a tag attached to an object, for the automatic driver identification. Reader can be connected to MDF device via 1-wire interface.
  • iButton 1-Wire® : iButton is a special driver identification chip based on 1-wire protocol. External 1-wire iButton reader can be used in parallel with MDF devices
  • Temp. 1-Wire® : A temperature sensor which can be connected to MDF device and provide information via 1-wire data protocol.
  • Immobilizer : With this scenario vehicle can be used only if iButton is connected. You can connect any iButton to pass Immobilizer security. MDF device Digital Output 2 is controlled by scenario for user needs (for example: LED, buzzer or other indicator can be connected).
  • Green driving : Helps to prevent and inspect driver about harsh driving. This functionality works in parallel with accelerating force, braking force and cornering angles. Every harsh drive event can be presented in the real time during the LED or buzzer notification.
  • Fuel monitoring LLS : Fuel monitoring via LLS sensors gives ability to measurer are highly accurate fuel level in the vehicle. This functionality can be based on digital or analog connectivity.
  • Jamming detection: Jamming detection informs the driver with buzzer or LED about radio jamming events.
