GREENFIELD, Mass. - s4story -- The JCOM1939 Monitor Software is a powerful Windows application built to make SAE J1939 networks approachable, insightful, and efficient. Instead of staring at endless streams of raw data, users can filter, record, and analyze traffic in real time, simulate complete ECUs, scan connected devices, and design custom Parameter Group Numbers (PGNs). With its intuitive layout, the software transforms complex network behavior into understandable visuals, making it indispensable for engineers, developers, and educators who need reliable insight into heavy-duty communication.

Supporting the software is a family of JCOM1939 gateways that serve as the bridge between the vehicle network and your PC. Without these gateways, the monitor software would have no data to display. Each option provides a different approach, ensuring there is a solution tailored to every project.
