Product Overview

Integrated 3G/GSM module

Integrated 3G/GSM module

It makes this device usable worldwide, as there are countries which have only 3G network. User can choose if device will work only in GSM network, or will it prefer 3G network and switch to GSM only when 3G is absent.

Various vehicle CAN data

Various vehicle CAN data

With additional Max GPS Vehicle CAN adapter you will be able 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.



1-Wire® protocol support enables you to identify up to 500 authorized drivers and connect temperature sensor. According to iButton® or RFID ID you can prevent unauthorized access to your fleet and temperature sensor allows you to monitor your cargo.

Internal battery


Feel safe when vehicle is monitored by device with internal battery. When vehicle battery is disconnected, device still remains online and sends data to server.

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.

GNSS antenna detection


GNSS antenna disconnection detection will monitor the state of GNSS antenna. If any person cuts or disconnects the antenna, You will be immediately informed about such action.


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.


  • External GSM antenna : An antenna used for GSM connectivity. Connected to MDF device via external connector.
  • External GNSS antenna : An antenna used for GPS connectivity. Connected to MDF device via external connector.
  • DIN - digital input - 3 : 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.
  • 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.
  • NTP time synch.: Network time protocol (NTP) is used to get the right time without GPS connection. This functionality gives an ability to monitor the device state in the real time.
  • GNSS unplug detection : The GNSS unplug detection gives an ability to notify the User about GNSS antenna disassembly.
  • SMS event : SMS event is a special functionality which is used to notify the user about the tracker initial state. Any changes of speed, engine status, over speeding or etc. will be informed with SMS.
  • Idling detection: The Idling detection functionality allows User to monitor the engine working time without initial speed.
  • Odometer : Odometer is used to calculate traveled distance and produce this information directly to server.
  • Trip detection : Trip detection is used to inform user about start and stop points in the dedicated location, while engine is on or off.
  • Integrated scenarios : The integrated device scenarios are used to simply enable the dedicate functionality like Green driving, Over speeding, Authorized driving or Immobilizer.
  • Remote configuration over SMS : The remote configuration via SMS gives an ability to configure the device via SMS
  • Offline tracking : Offline tracking is used to track the object position while GPRS is not activated.
