We have finally implemented an old idea to provide better support for our customers. The “problem” is that many users are reluctant to read the dry user manual, finding it easier to watch a video instead. Therefore, we have created a YouTube channel to visually demonstrate the capabilities of the JCOM1939…

The JCOM1939 Monitor Software is the perfect tool for monitoring, recording, analyzing, and simulating SAE J1939 data traffic. It works in combination with our SAE J1939 gateways. This comprehensive, easy-to-use, and easy-to-understand Windows software displays SAE J1939 data traffic. It allows network scanning, simulating an ECU (including full node address…
Please be aware that you can only scan the network when you have chosen ECU Simulation Mode in the ECU Setup tab. Otherwise, the software will indicate that there is no node ID available. Click on the Scan Network command button, and the system will send a Request for Address Claimed message into the network. All other…
The Recorder function allows the user to store received (filtered) PGNs into an MS-Excel-compatible csv file. The control buttons are self-explanatory, since they resemble those of any standard recording device. Click Record to start the recording process, and the program will display the number of current records as shown above. After clicking the Stop button,…
In the Byte Data section of the jCOM1939Monitor software, the user can select a previously designed PGN, the data start position, and the data length (1, 2, 3, or 4 bytes). The program will display the data as selected and allows the user to modify the data either per text input or…
The Bit Data section was designed with the modification of digital signals in mind. It functions very similar to the Byte Data section, however, limited to one byte. Also, instead of a slider, the program uses check boxes to set or reset digital information. → Download/View the JCOM1939 Monitor User Manual (PDF)… A Comprehensible…
If your intention is the mere monitoring of SAE J1939 data traffic, you don’t need to set up the ECU, but if you want to transmit SAE J1939 data (PGNs), you need to claim a node address. This section is where you configure an SAE J1939 ECU through parameters such…
The Filter section allows you to filter any PGNs (Parameter Group Numbers) from your network. Simply enter the PGN of your choice and a description (optional), then hit the Save command button. The PGN, provided it is part of your J1939 data traffic will show on the data screen below. If you…
Please be aware that you can only transmit messages when you have chosen ECU Simulation Mode in the ECU Setup tab and you have claimed an ECU address (see paragraph ECU Setup above). Otherwise, the software will indicate that there is no node ID available. You can design messages by entering the PGN, Destination Address (255…
As you can gather from above image, the program lists all received PGNs according to the PGN filter settings. The displayed information includes: PGN Index PGN Source Address – SA Destination Address – DA Priority Message Length Data Description (assigned in PGN filter settings as described below) As of Version…
