CAN bus display

MasterCAN Display 35 – CAN bus display / HMI device designed for displaying CAN J1939 parameters and data from additional fuel level sensors, fuel flow meters, axle load sensors and other peripheral units used in vehicle telematics systems or stationary machinery monitoring system.

Parameters shown on the screen of CAN bus display can be selected from S6 database containing over 10,000 SPN (parameters) of machinery operation, used in CAN J1939, ISOBUS and CAN j1939/S6 Telematics Interface.

Core features of CAN J1939 display

  • Displaying 402 parameters, selection from S6 Database‘s 10,000+ SPN,
  • automatic CAN J1939/71 and ISOBUS messages scanning and parsing,
  • possibility to parse and display proprietary CAN bus message,
  • embedded converter of analog signal to CAN interface messages
  • flexible configuration, adding/deleting screens, parameter and units naming

In vehicle telematics MasterCAN Display 35 is used as a dash mounted CAN display helping driver/machinery operator to monitor the most important engine (or other ECUs) operation parameters and to get readings from additional sensors and devices of tracking & monitoring systems (AVL) of construction equipment, agricultural machinery, railway vehicles, water transport, mining equipment and special vehicles for geological exploration and oil production, as well as in systems for remote monitoring of power (diesel) generator and boilers/burners sets.

Also, MasterCAN Display 35 can be employed for solving single tasks like: axle load display (i.e. on-board vehicle and/or semi-trailer axle load monitoring), fuel consumption monitoring system display or fuel tank monitor.

Vehicle manufacturers can consider including MasterCAN Display 35 as an optional “on request” equipment for providing their customer with additional possibility of on-board CAN bus parameters monitoring.

MasterCAN Display 35 features

Display CAN J1939 data

Flexible screen setting

Displaying up to 402 parameters, split into 21 group containing 20 parameters each. Flexibility of CAN J9139 display configuration includes: selecting to show 1 or 2 parameters per screen, uploading custom parameter icons, rename parameter or measuring units, add new screens in a group or remove screens from groups.

Industry-specialized models “Truck”, “Tractor” and “Marine” have preset screen groups for reducing efforts and time spent for configuration by installation technician.

Ready-made product, no SDK required

MasterCAN Display 35 is “out-of-the-box” product, which does not require further programming or user interface development, no HEX value calculations needed.

Configuration of MasterCAN Display 35 involves selecting network address of data source (engine, sensors, etc.), selecting from a drop-down list parameters to be shown on screens , adding/deleting screens, overlaying bit masks for detected proprietary CAN messages only (manual CAN bus parsing), renaming parameters or measuring units.

Automatic scanning and parsing CAN and ISOBUS

Over 10,000 parameters (SPN) described by J1939 (commercial vehicles) and ISOBUS (agricultural machines and equipment) are available to be shown on the screens of MasterCAN Display 35. After screen configuration, the display will automatically scan CAN bus and recognize available parameter groups (PGN).

The display can also show proprietary CAN J1939/71 messages, received from third-party developed devices with CAN-interface.
