Modern heavy-duty vehicles and industrial equipment often contain dozens of Electronic Control Units (ECUs) communicating over an SAE J1939 network. During manufacturing, every ECU must be verified before it leaves the production line. Whether the product is an engine controller, telematics unit, instrument cluster, display, gateway, data logger, or sensor…

Why We Created the J1939 Community If you work with SAE J1939, you already know that finding reliable information isn’t always easy. While the standard itself is comprehensive, applying it to real-world embedded systems, diagnostics, CAN bus monitoring, or software development often raises questions that aren’t answered by the specification…
Why the SAE J1939 Starter Kit Is the Best Choice for Learning and Developing Embedded J1939 Systems When engineers first enter the world of SAE J1939, they often ask a simple question: Should I start with a single J1939 gateway or buy the complete Starter Kit? While the SAE J1939…
In previous quick demos, we focused on SAE J1939 parameters that are transmitted periodically, such as engine speed, vehicle speed, fuel level, and engine temperatures. These messages are broadcast automatically at predefined intervals, allowing any node on the network to receive the data without explicitly asking for it. The Vehicle…
Engine speed is one of the most frequently monitored parameters in any SAE J1939 network. Whether you are developing a dashboard, testing an engine ECU, validating telematics software, or learning how J1939 communication works, engine speed is often the first parameter engineers look at. In this post, we will explain…
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…
