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.
In-built database of SPNs, which can be shown by CAN bus display, includes over 10,000 operation parameters of machinery described and standardized by CAN J1939 and ISOBUS specifications, also by CAN j1939/S6 Telematics Interface.
Core features of CAN J1939 display
- Displaying up to 402 parameters, which can be selected from in-built S6 Database containing 10,000+ possible SPNs,
- 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 measuring 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
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, if needed.
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.
CAN bus display in telematics system
The following equipment for vehicle tracking/machinery telematics can be connected to MasterCAN Display 35:
- standard automotive (engine) CAN J939 and J1708 buses
- external equipment sending CAN J1939/71 messages
- 16 fuel level sensors
- 16 fuel flow meters
- 2 axle load sensors
- 42 senders with voltage/frequency/current/digital outputs (via DAC converter)
- telematics gateway or vehicle tracking device (AVL unit) with CAN bus interface
Examples of data on MasterCAN Display 35 screens
From standard CAN bus
- engine operation time, engine RPM;
- coolant and oil temperature, oil pressure;
