UM AX032200 Version 1.0 4-46
GENERAL INFORMATION
1.1. Introduction to AX032200 Features
The AX032200 electronic control unit (ECU) is designed to provide a simple interface between
J1939 CAN network and discrete electronic devices in a power generator set or industrial
environment. The hardware supports 1 digital input or ignition, 2 digital outputs. Each of the two
outputs have current feedback to the microprocessor.
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 usin
g Axiomatic Technologies’ Electronic Assistant. Information
about the setpoint defaults and ranges is outlined in Section 4. The EA communicates with the
controller over the J1939 CAN bus and uses Memory Access Protocol (MAP) to read/write each
setpoint. Once the ECU has been setup as desired, the setpoints can be saved to a file, and
flashed into other controllers over the CAN bus using EA.
The ECU is an arbitrary address capable ECU, which can perform dynamic address allocation at
the run time. It also provides all necessary network support required by the J1939 standard.
