CONFIGURATION PARAMETERS
The converter configuration parameters can be viewed and changed using the standard J1939
memory access protocol through the CAN bus using Axiomatic PC-based Electronic Assistant
®
(EA) software.
4.1 Electronic Assistant Software
Axiomatic provides PC-based Electronic Assistant
®
(EA) software to communicate with a wide
range of Axiomatic products, including this converter. The software can be downloaded from
Axiomatic website
The EA uses the Axiomatic USB-CAN converter P/N AX070501 to connect to the CAN
network. The converter with cables can be ordered as an EA kit P/N AX070502.
Please, refer to the user manual UMAX07050X for description of the EA and associated
products, and for the CAN network connection troubleshooting.
The most recent EA software version can be downloaded from Axiomatic website.
Before connecting to the CAN network, the user should ensure that the EA baud rate is the
same as the baud rate used by ECUs on the network. The EA baud rate is displayed in the
bottom-right corner of the EA screen and can be changed in the
Options
menu.
If the converter is the only one ECU on a temporary network set for configuring the unit, the EA
baud rate should be set to the baud rate of the CAN network where the converter is planned to
be deployed. This baud rate will be stored in the ECU non-volatile memory and used by the
unit on the next power-up.
Upon connection, EA will show the converter on the list of ECUs that are present on the J1939
CAN network. If the converter is the only one ECU on the network, the following screen will
appear, see the figure below.

The user can then browse through the ECU parameters, read
General ECU Information
and
Bootloader Information
groups, view and modify configuration parameters, see Figure 28 figure
below.
The configuration parameters are grouped into function blocks. Please, refer to the appropriate
section of this manual describing the required function block.
In the
General ECU Information
group, the user will see the version number of the application
firmware. Please, make sure that the user manual version number matches with the most
