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.
