Compact and Robust Joystick Supports SAE J1939, CANopen Interfaces
Posted by on
Genge & Thoma AG introduced its series of joysticks for industrial and mobile applications with CANopen and SAE J1939 connectivity. The products address applications, including off-road vehicles and vehicle body applications.
The SK 60 joystick is a versatile product with several options with various haptic characteristics. The product is available in numerous configurations, with up to three axes depending on the handle. In the core of the joystick is a hall-effect sensor. In addition, the IP67-rated joystick comes optionally with a CAN Bus interface supporting the CANopen or SAE J1939 protocol stacks.
The SK197 joystick provides up to three axes based on potentiometer technology. The IP54-rated product also supports CANopen and SAE J1939. Therefore, it is suitable for remote control devices.
The SK212 multi-function joystick will operate under harsh environmental conditions. The IP65-rated product is appropriate for mobile hydraulics, agriculture, construction machines, and off-shore equipment. The joystick uses hall-effect sensors. Additional switches, thumbwheels, etc., can be applied. The product is available with CANopen and J1939 ports.
The Swiss company, established in 1958, exports about 90 percent of its joysticks. It has sales partners in many European countries, the U.S.A, Australia, China, Taiwan, and India. The company is a CiA member since 2017.
SAE J1939 Starter Kit And Network Simulator
The SAE J1939 starter kit allows you to monitor, simulate, and record any PGN as defined in the SAE J1939-71 Standard but also including diagnostic messages according to SAE J1939-73.
The starter kit was not designed to simulate specific diesel engines, but if you enter all PGNs that are being used, you can design and simulate any diesel engine.
ESP32 DC Motor PWM Speed Control (Pulse Width Modulation) - The Hidden Facts
Lately, I have worked on two projects requiring DC motor control per PWM (Pulse Width Modulation). What both projects had in common was a profound lack of documentation regarding PWM control, specifically the side effects that have a significant impact on the programming. This post aims to point to these quirks that may cause considerable headaches [...]
Thomson Electrac HD Linear Actuator - Fatal Error Flag at Low Speed
As part of a customer project, I was asked to develop a hardware system to control a linear actuator, specifically the Thomson Electrac HD model with SAE J1939 interface. The Electrac Linear Actuator is a great product, and it is always rewarding to see the application literally move. Yet, working on this application was at [...]
Thomson Electrak HD Linear Actuator - Multiple Actuators in the Same Network Will Empty the Batteries
Back in April 2022, I published a post, Thomson Electrak Linear Actuator with SAE J1939 Interface for Railway and Industrial Applications with the intention to use the gained knowledge and publish it in form of an application report. However, after months of working with this product (time frame, not efforts), I still discovered what I call [...]
SAE J1939 Diagnostic Device Includes a PGN, SPN Database
The handheld PCAN-Diag FD device from PEAK-System supports diagnosing communication on a CAN (FD) network. In addition, a separately available extends the functionality to analyze SAE J1939 data traffic. The SAE J1939 Standard describes communication in utility vehicles via CAN Bus. The standard specifies messages and data for transmitting diagnostic and control information using PGNs (Parameter Group Numbers) and SPNs [...]
SAE J1939 - Simulation of Request Message with J1939 to USB Gateway
The above image shows my SAE J1939 test setup with a total of three nodes, all connected through our CAN-Bus Hub with 7 Ports and DC Power Connection. They are: SAE J1939 to USB Gateway in Plastic Enclosure... SAE J1939 ECU Simulator Board With USB Port... PEAK PCAN-USB Pro FD - CAN, CAN FD, and LIN Interface for [...]
Quick Prototyping by Copperhill Technologies
As they say, a picture tells a thousand words. The above image demonstrates a predicament we encountered a few days ago. The enclosure we are using for our SAE J1939 Gateway And Data Logger With Real-Time Clock is not available at the moment, and it might take a few more months before new supplies arrive. At [...]
SAE J1939: Simulation of Analog and Digital Signals with the JCOM1939 Monitor Software
The JCOM1939 Monitor Software is ideal for monitoring, recording, analyzing, and simulating SAE J1939 data traffic. The system works in combination with our SAE J1939 gateways. This comprehensive and easy-to-use, easy-to-understand Windows software displays not only SAE J1939 data traffic but also scans the network, simulates an ECU (incl. full node address negotiation features), and responds [...]
Any CAN Bus, SAE J1939, NMEA 2000 Development Requires the Right Testing Tools
I want to reiterate a point made in a previous post ("A Beginner's Guide to SAE J1939 Embedded Software Development"): When developing and testing your CAN Bus application, may it be Classical CAN, CAN FD, CANopen, SAE J1939, or NMEA 2000, you need to connect your device to a functional network. One solitary node connected to your [...]
Data Acquisition from Heavy Duty Vehicles Using SAE J1939 CAN Bus
Modern vehicles have electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or ‘controllers’) are networked to convey information and output measured and calculated data to each other.This in-vehicle network is a data goldmine for improved maintenance, measuring vehicle performance and its subsystems, fleet [...]
