Developing, testing, or diagnosing SAE J1939 networks requires more than simply connecting a CAN interface to a PC. Engineers often need to monitor network traffic, decode messages, simulate electronic control units (ECUs), request diagnostic data, and verify that embedded software behaves correctly under real-world conditions. The market offers a wide…
A customer recently asked me a seemingly simple question: “Can I use your JCOM1939 Monitor software with my existing IXXAT CAN-to-USB interface?” Although the question was specifically about SAE J1939, the underlying issue has nothing to do with J1939. It is a problem that has existed in the CAN Bus…
When I published Comprehensible Guide to J1939 several years ago, I honestly didn’t know what to expect. Today, it continues to sell well, and I still receive emails from engineers telling me it helped them finally understand SAE J1939 after struggling with the official documentation. That feedback has always meant…
If you are new to SAE J1939 development, you may believe that access to a truck, engine, generator, or agricultural machine is required before you can write any meaningful software. While eventually you will want to test your application on real equipment, the majority of J1939 software development can be…
If you have recently started working with SAE J1939, chances are your search history looks something like this: How do I monitor J1939 traffic? What hardware do I need for J1939 development? How do I simulate a J1939 ECU? How can I test my software without connecting to a real…
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…
