Real-time tracking device with CAN-bus:


  • GSM/GPRS device designed for real time tracking of vehicles and cargo or supervising technical objects. It is intended for passenger, construction, money transport and agricultural vehicles, buses, trucks, etc.

  • DS540 communicates with server via GSM network. Device transmits location data (GPS/GLONASS position and speed) with current parameters and  events registered in monitored objects to external server using UDP or TCP protocol.

  • Due to analogue/digital inputs and interfaces (RS485, 1-wire) the device: a) measures data from 2 sensors with analogue output signal and from analogue/digital fuel level sensors, b) authorizes access to a vehicle via iButton identifiers, c) measures temperature via 1-wire sensors, d) monitors status of 2 switches. Due to digital outputs the device allows users to control 2 circuits remotely.

  • It reads data from CAN-bus of over 800 passenger cars: fuel level, engine RPM, door/trunk/bonnet status, OEM remote locking and unlocking of the vehicle, triggering vehicle OEM alarm etc.

  • DS540 reads from CAN/FMS/J1939/J1708 buses among others: fuel level, fuel consumption, engine RPM, engine load and temperature, tachograph data, door/trunk/bonnet status, OEM remote locking and unlocking of the vehicle, triggering vehicle OEM alarm.


  • Sending vehicle data from GPS, CAN, other interfaces and analogue/digital inputs via GPRS using UDP or TCP protocol.

  • Real-time transmission of vehicle geoposition, sampling grid dependent on speed and vehicle rotation angle.

  • Limiting data transfer by collecting larger amount of data into packets.

  • Intelligent report sending system, dependant on time, speed and events.

  • Separate report sending conditions for different device operating circumstances (external power supply or internal battery, roaming).

  • Intelligent algorithm for operation in roaming mode.

  • Memory holding up to 50000 reports (~85 hours of normal operation).

  • Upgrade Over The Air (OTA) - firmware upgrade via GSM/GPRS.

  • Remote configuration via GSM/GPRS.

  • Measuring of temperature from up to 4 digital temperature sensors.

  • Driver/load identification with contact 1-wire identifiers or contactless RFID identifiers.

  • Reading fuel level from CAN-bus (both trucks and passenger vehicles), from fuel level sender circuits, from analogue and digital RS485 fuel level sensors.

  • Reading fuel consumption from CAN-bus.

  • Low power consumption.

  • Power saving modes.

  • Compact and easy to install housing.

  • Advanced diagnostic tools, improving device installation and testing.
