JCOM1939 Monitor Pro-X Program Versions and Update

We needed to split the development of the Windows software and create a new, extended version that takes advantage of the more powerful features of the JCOM.J1939.USB-X and JCOM.J1939.REC boards.

The new version is called JCOM1939 Monitor Pro-X (“X” for extended).

JCOM1939 Monitor Pro-X ScreenThe jCOM1939 Monitor Pro-X Software is the perfect tool to monitor, analyze, and simulate SAE J1939 data traffic. The software utilizes our JCOM.J1939.USB-X gateway or our JCOM.J1939.REC data logger.

A comprehensive and easy-to-use, easy-to-understand Windows software displays not only SAE J1939 data traffic; it also allows to scan the network, simulate an ECU (incl. full node address negotiation features), and respond to data request messages.

The communication protocol between the gateway and the host system (PC, Embedded System, Android System, etc.) is well documented, and we provide C/C# source code to read and write CAN data frames.
