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…
This post will guide you through setting up SAE J1939 PGN simulation with our JCOM1939 Monitor software, using the Engine Coolant Temperature as a randomly chosen example. It’s important to note that you can configure any PGN with our software. However, it’s crucial to have the SAE J1939-71 Standard (available…
It happens regularly that I am contacted by a user of our SAE J1939 ECU Simulator Board with USB Port, complaining that our device does not display a PGN correctly or modify the PGN before transmitting. The real problem here is a misinterpretation of the PGN and its purpose. For…
Welcome to my beginner’s guide! By opening this page, you have entered the first and probably most crucial stage toward developing your SAE J1939 project: Reading. Over the years, I dealt with many newcomers to the J1939 technology, some motivated by great product ideas. Others were thrown into a project…
