Electromechanical Linear Actuators With Embedded SAE J1939 Interface For Mobile Off-Highway Applications
Thomson (US) introduced its Electrak MD electromechanical linear actuators with an embedded SAE J1939 interface. They are suited for mobile off-highway, material handling, and factory automation applications. The integrated features reduce space consumption by keeping external equipment (e.g., encoders, switches) within the actuator housing. This functionality provides straightforward control and communication methods. Besides the CAN Bus connectivity, the actuators [...]
Difference Between CAN Bus and SAE J1939 Data Logger
SAE J1939 has become the accepted industry standard and the vehicle network technology of choice for off-highway machines in applications such as construction, material handling, agriculture, and forestry machines. SAE J1939 is a higher-layer protocol that utilizes Controller Area Network (CAN Bus) as its hardware layer. Consequently, many vendors in the CAN Bus industry claim SAE [...]
SAE J1939 Gateway And Data Logger With Real-Time Clock - July 8, 2020
Our SAE J1939 Gateway And Data Logger is ideal for vehicle fleet management (trucks, buses, agricultural equipment, and any other diesel engine application), prototype field testing, diagnostics, or reverse engineering. The SAE J1939 Gateway And Data Logger records SAE J1939 message frames (PGNs) onto an onboard MicroSD memory card and timestamps them with a real-time clock (RTC). [...]
SAE J1939 Data Logger - SD Micro Card Capacity And Write Speed Requirements
Our SAE J1939 Gateway And Data Logger was designed for vehicle fleet management (trucks, buses, agricultural equipment, and any other diesel engine application), prototype field testing, diagnostics, or reverse engineering. The SAE J1939 Gateway And Data Logger records SAE J1939 message frames (PGNs) onto an onboard MicroSD memory card and timestamps them with a real-time clock (RTC). Alternatively, it [...]
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. It comes with an ISO 11898‑2‑compliant CAN Bus interface, which supports the 29-bit identifier extended frame format (CAN 2.0B) for SAE J1939 applications.Available with either the NXP i.MX6 Quad (quad-core), or the i.MX6 Duallite (dual-core) processors, the board carries an onboard Wi‑Fi, Bluetooth, [...]
