SAE J1939 Sensor Array Reports Vehicle Angular Rate, Acceleration, And Attitude Data Of Heavy-Duty, Off-Highway Vehicles
Honeywell's Tars (Transportation Attitude Reference System) series of 6D inertial sensor units allows the concurrent acquisition of rotation rate, acceleration, and tilt data for heavy-duty, off-highway, or other specialized vehicles. The sensors are available from SE Spezial-Electronic. The vehicle network protocol is SAE J1939. The reference sensor unit Tars-IMU operates either with a 5 VDC or 9 to [...]
ARM Cortex Automotive-Grade SoC (System on Chip) With Two CAN Bus Interfaces Supports Linux And Android BSP
Advantech announced the release of its ROM-5620 Smarc 2.1 module, its first Arm Cortex A35 based on the NXP i.MX8X application processor. The product is especially applicable for automation equipment and HMI (human-machine interface) devices.The product adopts an automotive-grade SoC (System on Chip) and associated industrial-grade components that provide an operating temperature range from -40 °C [...]
Data Acquisition from HD Vehicles Using The SAE J1939 CAN Bus
Modern vehicles are equipped with electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (Electronic Control Units) are networked to share information, and output directly measured and calculated data. The SAE J1939 in-vehicle network is a data goldmine for enhanced maintenance, measuring vehicle performance and its [...]
SAE J1939/13 Off-Board Diagnostic Connector Deutsch HD10-9–1939
The SAE J1939/13 document defines a standard connector for diagnostic purpose. The connector is a Deutsch HD10 - 9 – 1939 (9 pins, round connector). According to the document, the connector supports both the twisted shielded pair media (as defined in SAE J1939/11) as well as the twisted unshielded quad media (as defined by ISO 11783-2). The designations [...]
SAE J1939/16 Automatic Baud Rate Detection Process
The SAE J1939/16 document outlines the methods used to detect the baud rate of an SAE J1939 network segment by ECUs that can adjust their CAN baud rate while in use. The specified approach provides a reliable method to detect the CAN baud rate of that network segment without interrupting network communications. SAE J1939/16 defines the following requirements [...]
Single-Board ARM i.MX6 Computer Supports CAN Bus, WiFi, And Bluetooth
Versalogic introduced its Swordtail VL-EPC-2702 as part of a product series of ARM‑based embedded computers.

SAE J1939 And The Challenging Migration From Classical CAN To CAN FD and CAN XL
The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee has developed a family of standards concerning the design and use of devices that transmit electronic signals and control information among vehicle components. SAE J1939 and its companion documents have quickly become the accepted industry standard and the vehicle network of choice for off-highway [...]
Introduction To The NMEA 2000 Marine Networking Standard
NMEA 2000 is a marine networking standard created and administered by the National Marine Electronics Association (NMEA). The NMEA is an association of marine electronics manufacturers, dealers, and technicians. The NMEA 2000 standard describes a low-cost, moderate capacity, bi-directional, multi-transmitter, multi-receiver instrument network. Typical data on a network using this standard include position latitude and longitude, [...]
