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.
