  • Page 4: Introduction To Ax030440 Features

    The ECU has been designed to allow the maximum amount of versatility to optimize the performance of the machine. Numerous configurable variables, called setpoints, have been provided which are accessible using Axiomatic Technologies’ Electronic Assistant. Information about the setpoint defaults and ranges is outlined in Section 3. The EA communicates with the controller over J1939 CAN bus and uses Memory Access Protocol (MAP) to read/write each setpoint.
