High Accuracy CAN Bus Transducer With SAE J1939 Support
The GP:50 Model 541 CAN-connectable pressure transducers are intended for brake, dynamometer, hydraulic valve, jet engine, and transmission testing. They can be installed in test stands. The products feature higher resolution, reduced noise, and improved thermal performance compared to the Model 540 predecessor series. The welded stainless steel design of the Model 541 offers ease of installation within space constrained [...]
SAE J1939 CAN Range Of Hydraulic Sensors For OEM Mobile And Industrial Applications
The new SAE J1939 CAN range of hydraulic sensors from Webtec (Milwaukee, WI) are designed for OEM Mobile and Industrial applications where the user needs real-time continuous monitoring of hydraulic flow, pressure and temperature on high-pressure hydraulic systems for closed loop control, to predict imminent hydraulic failure or for diagnostic fault-finding. The CT turbine flow meter range with [...]
CAN Bus and SAE J1939 Wiring Requirements And Trouble-Shooting
Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry, especially for European cars, but has also become a popular bus in industrial automation as well as other applications. The CAN bus is primarily used in embedded systems, and as its name implies, is a network technology that provides [...]
SAE J1939 ECU Simulation And Data Monitoring Under Linux
Our JCOM.J1939.USB gateway board is a high-performance, low-latency vehicle network adapter for SAE J1939 applications. It allows any host device with a USB COM port to monitor SAE J1939 data traffic and communicate with an SAE J1939 vehicle network. The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 [...]
Non-Contact Rotary Position Sensor With J1939 Output For Vehicle Applications
Curtiss-Wright’s Industrial division has launched the NRH27C, a non-contact rotary position sensor which is suitable for on- and off-highway vehicles utilizing CAN Bus communications. The full range of the digital output span corresponds to a rotation of 360°, and the positional information is determined by the angle of the supplied magnet relative to the sensor body. The maximum [...]
CAN Bus And SAE J1939 Recording and Simulation Using the Raspberry Pi
The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries. The original model became far more popular than anticipated, selling outside of its target market for uses such as robotics. Peripherals (including [...]
SAE J1939 Turbo Interface for Raspberry Pi - Firmware Update
The jCOM.J1939.RPi, an SAE J1939 interface for the Raspberry Pi, is not an RPi HAT in the common sense. The board incorporates an ARM processor with CAN transceiver for use on the Raspberry Pi while allowing the operation with any other RPi-compatible board.By combining our J1939 port interface, the Raspberry Pi, an SAE J1939 cable, and [...]
"C" Programming The SAE J1939 Turbo Interface for Raspberry Pi
The jCOM.J1939.RPi, an SAE J1939 interface for the Raspberry Pi, is not an RPi HAT in the common sense. The board incorporates an ARM processor with CAN transceiver for use on the Raspberry Pi while allowing the operation with any other RPi-compatible board.By combining our J1939 port interface, the Raspberry Pi, an SAE J1939 cable, and [...]
Authentication And Encryption for SAE J1939 And Other CAN Bus Protocols
At the time when the Controller Area Network (CAN) standard was designed, security was not a requirement. The primary usage of the CAN Bus was considered complete; possible intruders or attackers would simply not get physical or remote access to the network. However, today it is more and more common that devices connected to a CAN [...]
Position Control With Embedded J1939-Compliant Linear Actuator Is Superior To Hydraulic Actuator
Manufacturers of agricultural, construction, and other off-highway equipment are increasingly deploying electromechanical actuators instead of hydraulic actuators, the primary reason being their simplicity and environmental benefits. Now, intelligent electromechanical actuators that support the Controller Area Network (CAN) bus networking standard give designers more reasons to choose such a solution. Support for the CAN/J1939 networking protocol [...]
