SAE J1939 is the 29-bit CAN ID protocol originally devised for coordinating the communication of ECUs within a typical truck and trailer system. The J1939 option for the X-Analyser means that users can view raw CAN data, engineering signals and the J1939 interpretation in terms of packet interpretation, all within X-Analyser’s intuitive graphical user interface.

The J1939 interpretation feature for X-Anlayser supports all of the main features of the X-Analyser plus the following: -

  • Source and Destination filtering (show ALL or Individual source or destination)
  • Protocol Data Unit Filtering (PDU1, PDU2)
  • Data is displayed as: -
  • Source
  • Destination
  • PDU – Protocol Data Unit
  • PGN – Parameter Group Number
  • Pr – Priority
  • PD – Page Data
  • Date Field
  • Textual description

A signals file is provided that gives interpretation of signals as per specification J1939-71.
