Guide To SAE J1939 - Communication Methods
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. SAE J1939 provides three communication methods, each serving a specific purpose.1. Destination Specific Communications:Destination specific communications use PDU1 (PF values 0 to 239), but also the global destination address 255. There are cases where this method will require the utilization of destination specific Parameter Group Numbers, for instance, [...]
SAE J2534-1 And J2534-2 Device Supports CAN FD Plus Four CAN Bus Channels
Drew Technologies (USA) improved their J2534 devices by adding a CAN FD port. The Cardaq-Plus3 complies with the SAE J2534-1 and J2534-2 application programming interface specifications. It comes with one CAN FD and four standard CAN Bus interfaces. Additionally, it supports DoIP (Diagnostics over IP), which goes beyond the three-port requirement for some Chrysler/FCA models.Also, the product features High-Speed USB [...]
CAN Bus Transceiver Modules With Isolated DC/DC Converter In One Module
Mornsun CAN Bus transceiver modules replace the traditional design by integrating transceiver, isolation chip, and high efficient DC/DC isolated power in one module. The modules can be used for inter-communications between devices on the industrial bus, achieving the signal transmission and power isolation. They target the automotive industry, rail transportation, smart monitoring, smart meters, and more.Mornsun [...]

As in previous editions, different topics appear in a compact, but descriptive way backed up by diagrams, graphs, photographs, and tables allowing the reader to understand the subject better. This fifth edition [...]
SAE J1708 to UART Breakout Board - Programming SAE J1708 Network Access
We at Copperhill Technologies have designed an SAE J1708-to-UART breakout board, and we are in the process of adding it to our e-commerce website. However, what we learned during the development is that the device is in need of some massive software support as I will explain in the following.First of all, to go into [...]
Guide To SAE J1939 - J1939 Characteristics
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. SAE J1939 is a higher-layer protocol based on Controller Area Network (CAN). It provides serial data communications between microprocessor systems (also called Electronic Control Units - ECU) in any kind of heavy-duty vehicles.Everything that has to do with CAN is based on maximum reliability with the [...]
Guide To SAE J1939 - Controller Area Network and J1939
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. The standard CAN message frame uses an 11-bit message identifier (CAN 2.0A), which is sufficient for the use in regular automobiles and any industrial application, however, not necessarily for off-road vehicles.The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee had developed a family of [...]
Guide To SAE J1939 - CAN Bus Higher Layer Protocols
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. Even though extremely effective in automobiles and small applications, CAN alone is not suitable for machine automation, since its communication between devices is limited to only 8 bytes per message. As a consequence, higher layer protocols such as CANopen for machine control, DeviceNet for factory automation and [...]
CAN-to-Cloud Gateway Connects CAN Bus to Microsoft Azure Cloud Via Ethernet
The CAN-to-Cloud device by esd electronics connects a CAN Bus network to Microsoft Azure Cloud using Azure IoT Hub. Once transferred to the Cloud, the data can be processed according to the user's needs. Microsoft Azure offers a multitude of software services for further processing, such as storing, displaying, and analyzing process data. The service also allows the designing [...]
Guide To SAE J1939 - Introduction to J1939
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. 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 [...]
