SAE J1939 diagnosis made easy
The Chemnitz-based electronics company GEMAC extends the functionality of diagnosis device CAN-Bus Tester 2 and software tool CANvision® by adding a protocol monitor for SAE J1939 to its portfolio.
The company GEMAC – Gesellschaft für Mikroelektronikanwendung Chemnitz mbH has launched the software license “protocol monitor SAE J1939” for its CAN-Bus Tester 2 making further diagnosis possibilities available to the user of the only diagnosis device that test CAN bus systems logically AND physically. The software tool CANvision® has also been extended by a license client for SAE J1939 which enables the user to analyze SAE J1939 data via the network without having to be present at the place of the actual measurement.
This protocol extension for CAN-Bus Tester 2 and CANvision® eases the familiarization with the protocol SAE J1939 and allows the user to quickly start analyzing the data of SAE J1939 based systems. The optional extension decodes and displays the source address, the parameter group (PGN – Parameter Group Number) and the individual signals (SPN – Suspect Parameter Number) specific to SAE J1939 whilst taking into consideration the transport protocols BAM (Broadcast Announce Message) and CMDT (Connection Mode Data Transfer). For a better overview the data can be filtered, sorted and highlighted in different colors. A fully integrated SAE J1939 database eases the setting of the filter criteria.
With this protocol extension for SAE J1939 GEMAC’s CAN-Bus Tester 2 and the program CANvision® become ideal tools for the analysis of SAE J1939 based communication protocols used in utility vehicles, agricultural and forestry machines, fleet management systems (FMS), networks between trucks and their trailer as well as in the shipbuilding industry.
About SAE J1939
SAE J1939 is a standard for the data communication in utility vehicles maintained by the international Society of Automotive Engineers (SAE). It works on the physical layer with CAN-Highspeed in accordance with ISO 11898. The ISO standard 11783 (ISOBUS) used in agricultural vehicles is based on the SAE J1939 standard just like the communication protocol NMEA 2000® of the National Marine Electronics Association (NMEA®) used in the shipbuilding industry builds on SAE J1939. GEMAC’s protocol monitor for SAE J1939 therefore supports the user in analyzing these two standards as well.
