JCOM.J1939.REC – SAE J1939 Gateway And Data Logger With Real-Time Clock

This product is under current development…

Targeted release date is September 2020. For further information, please feel free to contact us.


SAE J1939 Gateway And Data Logger With Real-Time ClockThe SAE J1939 Gateway And Data Logger is ideal for vehicle fleet management (trucks, buses, agricultural equipment, and any other diesel engine application), prototype field testing, diagnostics, or reverse engineering.

The SAE J1939 Gateway And Data Logger records SAE J1939 message frames (PGNs) onto an onboard MicroSD memory card and timestamps them with a real-time clock (RTC). Alternatively, it can be used for mere SAE J1939 data monitoring and viewing.

In record mode, the gateway reads the data traffic without being connected to a PC. A free-of-charge Windows software is available for the device setup (PGN filtering, message-sampling frequency, etc.) as well as reviewing and re-playing the SAE J1939 data.

The data file format is Microsoft-Excel-compatible (.csv), and the data file can be retrieved directly from the SD card for further processing. Alternatively, the board acts as a USB memory stick, allowing easy access per PC.

Furthermore, the data logger offers an optional feature to include GPS information attached to the data (requires additional onboard GPS sensor).

Testing the Device:

Please, make sure you download our free-of-charge JCOM1939 Monitor Software for Windows. The current combination of prototype hardware and Windows software will allow you to record and store SAE J1939 data to a PC file.

We are working to update the firmware and the Windows software to have the device record data without the need of an attached PC, and we will update/document the progress here on this page.
