  • Page 5: General Information

    Axiomatic Technologies’ Electronic Assistant. Information about the setpoint defaults and ranges is outlined in Section 3. The Axiomatic EA communicates with the controller over J1939 CAN port#1 and uses Memory Access Protocol (MAP) to read/write each setpoint.

  • Page 6: Control Sources

    However, in some applications this broadcast may not be required and so the user has the option to disable or enable this feature. Section 3.1 shows the configuration of this feature by using the Axiomatic Electronic Assistant tool. 1.3. Control Sources The different function blocks in the ECU are commanded by a set of Control Sources.
