Telematics Gateway Connects to Multiple SAE J1939 / ISOBUS Sensors
The CANUp telematics gateway by Technoton represents a multi-functional tool for advanced telematics systems combining data interface features, a digital-to-analog converter, and an online GPS/GLONASS tracker. The telematics gateway allows the easy and error-free implementation of a complex telematics system that uses many onboard smart sensors and devices to monitor multiple control points: fuel tanks, engines, upper [...]
Controller Area Network (CAN Bus) Tutorial - Higher Layer Protocols
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. Even though highly influential in automobiles and small applications, the CAN Bus technology alone is not suitable for machine automation since its communication between devices is limited to only 8 bytes. Consequently, higher layer protocols such as CANopen for machine control, DeviceNet for factory [...]
Controller Area Network (CAN Bus) Tutorial - Extended CAN Protocol
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. The standard CAN message frame uses an 11-bit message identifier (CAN 2.0A), which is sufficient for use in regular automobiles and industrial applications but not necessarily for off-road vehicles. The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee developed a [...]
A Simple SAE J1939 to USB Gateway with the Arduino Uno, Mega 2560, Due, Teensy, ESP32
The following is an excerpt from SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino by Wilfried VossI deem it necessary to clarify the definition of “SAE J1939 to USB Gateway” because there are several variants of gateway applications.If you browse through the Internet in search for SAE J1939 gateways, you will primarily find CAN [...]
What is the Difference Between SAE J1939 and NMEA 2000?
After developing and programming multiple SAE J1939 devices over the years, I was curious to determine the difference between SAE J1939 and NMEA 2000. There are some valid reasons why I didn't consider an expansion into NMEA 2000, and they all have to do with the immense costs related to NMEA 2000 development. First of [...]
Build an ELD Better, Faster, and Cheaper Than KEEPTRUCKIN, Samsara, and Others
To mention it upfront, I am not suggesting building the best ELD (Electronic Logging Device) solution in the market. Such systems already exist, and while I like the idea of disrupting the market, I deem such an attempt extremely time-consuming, thus expensive, and most likely not worth the efforts. In other words, KEEPTRUCKIN and Samsara [...]
Data Converter Transforms SAE J1939 and SAE 1708/1587 Messages Into Single SAE J1939 Data Frames
The MasterCAN data converter series by Technoton serves as an interfacing and transformation tool between CAN J1939/71, J1708 (SAE J1587), and RS-485/232 (Modbus RTU) communication devices, designed for vehicle telematics (GPS vehicle tracking) and industrial automation (IIoT). The MasterCAN data converter is suitable for integrated sensors and peripherals with different interfaces into single telematics and remote management system. [...]
User-Configurable CAN to LIN Gateway Can Act As A Bi-Directional CAN-LIN Bridge Or Remote I/O Module
The CAN-LIN Gateway ECU by Mach Systems is an electronic control unit with two CAN/CAN FD channels, a LIN Bus port, and various multi-purpose digital/analog inputs and outputs. The control unit is completely configurable and can operate as a stand-alone data converter between a CAN/CAN FD and a LIN bus network or remote I/O modules to connect vehicle [...]
SAE J1939 Data Recorder - Programming And Data Retrieval
The following is an update on our activities regarding our development of an SAE J1939 data recorder. The development affects two of our devices, the SAE J1939 Gateway Module With USB Port, RTC, MicroSD Memory Card and the SAE J1939 Gateway And Data Logger With Real-Time Clock. Both gateways are supported by our free-of-charge jCOM1939 Monitor, an SAE J1939 [...]
Testing The SAE J1939 to RS232 & USB Gateway By Copperhill Technologies
In this post, I will demonstrate the test setup of our SAE J1939 to RS232 & USB Gateway. The JCOM.J1939.SER gateway is a high-performance, low-latency, serial vehicle network adapter for SAE J1939 applications. It allows any host device with an RS232 or USB port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle [...]
