Modern vehicles have electronic control units (ECUs) to manage various subsystems, such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or simply ‘controllers’) are networked together to share information and output both measured and calculated data directly to one another. The SAE J1939 in-vehicle network is a…

The SAE J1939-22 standard addresses the issue of limited bandwidth for future data-demanding applications when using Classical CAN as the hardware layer. The proposed solution is CAN FD, which enables larger data frames and higher transmission speeds. However, the originally envisioned backward compatibility has not been achieved. The Bandwidth Issue…
The JCOM1939 Monitor Software is the perfect tool for monitoring, recording, analyzing, and simulating SAE J1939 data traffic. It works in combination with our SAE J1939 gateways. This comprehensive, easy-to-use, and easy-to-understand Windows software displays SAE J1939 data traffic. It allows network scanning, simulating an ECU (including full node address…
Things are going smoothly with our software development, and we are ready to present another update to the JCOM1939Monitor Software for Windows. This time, we would like to introduce Version 4.00.00. The jump in version number indicates a major change in how we present the PGN data. In detail: With…
This post refers to a simplified version of our SAE JCOM1939 Monitor – JCOM1939 Monitor, Analyzer, and ECU Simulator, a C# application created in Visual Studio. The JCOM1939 Monitor Software, a unique and powerful tool, allows you to monitor, analyze, and simulate SAE J1939 data traffic. It works seamlessly with…
What is the FMS Standard? At the turn of the 21st century, GPS-based vehicle tracking systems were becoming more affordable, yet they still lacked the capability to provide vehicle-related technical information. In a significant industry development, six leading truck manufacturers (Volvo, Scania, Iveco, MAN, DAF, Mercedes-Benz) joined forces in 2002…
The Address Claiming Process is the cornerstone of Network Management in the context of J1939. Unlike other higher-layer protocols based on Controller Area Network (CAN) that lack default support for dynamic node address assignments, the SAE J1939 standard stands out with its ingeniously designed feature. This feature allows for unique…
Our JCOM.J1939.USB gateway board is not just a high-performance, low-latency vehicle network adapter for SAE J1939 applications. It’s also a powerful tool that allows any host device with a USB COM port to monitor and simulate SAE J1939 data traffic. This unique feature makes it an invaluable asset for…
