MasterCAN DAC

J1939 i/o module MasterCAN DAC

MasterCAN DAC15 – is smart tool for GPS/GLONASS vehicle monitoring systems,  where analogue on-board equipment is used along with digital CAN/S6 equipment.

MasterCAN DAC15 used for converting:

1) Digital data (SPN) of automotive interface CAN/S6 to analogue inputs of telematics terminal or dashboard.
2) Analogue output signals of automotive sensors to CAN/S6 ports of telematics terminal.

Tasks

Vehicle operation monitoring according to data from standard, additional and attachments equipment:

  • data transmittion from analog sensors to the CAN input of the telematics terminal and/or dashboard
  • data transmittion from standard CANbus and telematic sensors with CAN/S6 interface to analog dashboard and/or telematics terminal with analog inputs

Application of MasterCAN DAC15

Advantages of MasterCAN DAC15

  • Complies with European automotive industry standards
  • Compliance with units, database and cabling system S6 Technology
  • IoT Burger Technology provides internal data processing (parameter filtration and normalization, events logging, counters recording) for easier server operation and data traffic saving
  • Increases quantity of vehicle parameters monitored through CAN j1939/S6 by converting output signals from analogue sensors to  telematics interface
  • Connects safely to standard on-board CANbus through CANCrocodile contactless reader
  • Integrates converted data of CAN j1939/S6 automotive bus to telematics system when terminal equipped by analogue inputs is used
  • Ensured compatibility with majority of telematics terminals and dashboards through possibility of output signal setting and adjustment
  • Power-supplied by on-board electrical system of vehicle – does not require external power sources

Converting CANbus data to analogues signals

MasterCAN DAC15 converts digital data (SPN) automotive CANbus (SAE J1939) to various types of analogue signals (voltage, frequency, pulse, current, discrete, resistive) for further transfer with data logging devices having correspondent analog inputs.

MasterCAN DAC15 combined with CANCrocodile contactless reader can be used as an out-of-the-box solution for integration of vehicle CAN bus essential data into vehicle telematics system through analog inputs of the tracking device.

Converting CANbus data to analogues signals

MasterCAN DAC15 used with DUT-E CAN fuel level sensor is a ready solution for accurate fuel volume measurement in vehicle’s fuel tank and volume indication on a standard vehicle’s dashboard.

Converting S6 Telematics interface data to analogues signals

Converting GNOM axle load sensors’ analogue signals to CAN/S6 Telematics Interface data

MasterCAN DAC15 converts analog signals of vehicle sensors into digital parameter values (SPN) of CAN (J1939) bus for further transfer with data logging devices having CAN interface port.
MasterCAN DAC15 is useful for data accumulation and analog signal transformation of GNOM DDE  axle load sensor for transfer of converted parameters (SPN) into telematics bus CAN/S6.

Fuel Gauge. Monitoring of fuel using standard fuel level sensor in fuel tank

  • For vehicles where fuel level data is not available from CAN bus
  • Converts analog signal of vehicle’s standard fuel level sensor into digital data (SPN) as per SAE J1939
  • Saves tank calibration table in internal memory, for higher accuracy of fuel volume measurement
  • Combined operation with FMSCrocodile allows transfering FMS data to telematics unit
