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.

 - Check your tracker clock setup is set UTC-0 or GMT. (The most trackers come from the factory on UTC.)
 - For most devices you should use IMEI (International Mobile Equipment Identity) number as unique identifier. However, some devices have vendor specific unique identifier, for example TK-103 devices use 11-digit identifier.
 - 
        Set Up the IP and port on your tracker: (automatic detect tracker's protocol.)
