SAE J1939 vs. CAN Bus - What's the Difference?
To say it upfront, the difference between SAE J1939 and CAN Bus (Classical CAN and CAN FD) has all to do with so-called "Higher Later Protocols (HLP)," and SAE J1939 is one of them. I have written a post about HLPs (see: Guide to SAE J1939 - CAN Bus Higher Layer Protocols), but I would like [...]
CAN FD Data Logger For CAN Bus Monitoring, DBC Logging, Message Filtering, SAE J1939 Logging, And Trigger Events
Influx Big Data Solutions introduces their ReXgen 2 CAN Bus logger, one of the smallest, compact, robust, and powerful handheld CAN Bus data recorder available in the market today. The device is targeted at applications requiring CAN 2.0 and CAN FD data recording capabilities. The data logger comes with a freely distributable ReXgen data logger configuration [...]
Telematics Gateway With SAE J1939 Data Logging For Predictive Maintenance Of Diesel Engines
The Telematics Gateway from iWave represents a vehicle diagnostics system for monitoring critical vehicle parameters from any place. The device supports four CAN Bus interfaces, including CAN FD, and is suitable for heavy-duty trucks, off-road vehicles, emergency vehicles, and vessels.The gateway utilizes parameters such as location, working duration, engine performance, and engine parameters that require continuous [...]
Multi-Functional Telematics Gateway Processes SAE J1939, ISOBUS Parameters For Predictive Maintenance
The CANUp telematics gateway by Technoton represents a multi-functional telematics unit for use in advanced machinery telematics systems. Advanced machinery includes mobile and stationary objects, which have many operation monitoring parameters for engines, power generators, boilers, various additional equipment, and other assemblies. The core features of the CANUp telematics gateway include: Reading over 10,000 machine operation parameters, thus the [...]
CAN Bus, SAE J1939, NMEA 2000 Programming With ESP32, Supporting USB, Bluetooth, BLE, And WiFi
The ESP32 Series of modules by Espressif supports the integration of WiFi, Bluetooth, and Bluetooth LE for a wide range of applications, most prominently for IoT (Internet of Things). For instance, using WiFi ensures connectivity within a large radius. Using Bluetooth allows the user to easily detect (with low-energy beacons) a module and connect it to [...]
ESP32-Azure IoT Kit For Sensor Data Acquisition And Cloud Platform Access
The ESP32-IoT development board by Espressif provides powerful functions that are specifically designed for sensor data acquisition, cloud platform access, and a broad spectrum of applications.ESP32-Azure IoT Kit supports innovative network configuration, cloud platform access, and sensor data acquisition. It is part of the product list of Microsoft’s Azure IoT solutions, and Espressif is an official partner of Microsoft's IoT [...]
AI Vehicle Computer For Machine Learning, Computer Vision, Sensor Fusion Supports Two CAN Bus Interfaces
Syslogic Industrial Computing introduced its AI railway computer RSL A3 for AI-assisted railroad applications. It comes with two CAN Bus interfaces. The device utilizes the recent Nvidia Jetson AGX Xavier industrial System on Module (SOM), created for challenging environmental conditions. The module features a 512-core Nvidia Volta GPU with 64 Tensor cores, two Nvidia deep learning accelerators, two [...]
The Two Elements of the SAE J1939 Protocol Stack
Any SAE J1939 hardware must support SAE J1939/1x and SAE J1939/21; otherwise, they’re useless because these standards describe the CAN bus physical layer and the basic protocol features. That part is sufficiently covered (i.e., for demonstration purposes) by our CAN shield, while the cabling and connectors may not necessarily J1939-compliant. A fully functional SAE J1939 protocol software [...]
Telematics Gateway For Automatic SAE J1939 and ISOBUS Scanning and Parsing
The CANUp telematics gateway by Technoton couples the functionality of two vehicle data interfaces, a digital-to-analog converter and an online GPS tracking device. The gateway scans and automatically parses 10 000 SAE J1939/71 and ISOBUS parameters and transmits selected data to a web-based telematics server or by email/SMS to a user. It applies edge computing algorithms for onboard [...]
Guide to SAE J1939 - Parameter Group Number Compilation
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. For internal purposes, the parameter group number is extended to 24 bits = 3 bytes, where the most significant 6 bits are always set to zero. Each ECU must accomplish this process individually; this procedure is not part of the CAN standard. To compile [...]
