FIRMWARE UPDATE
The converter firmware can be updated through the website in the field
The update procedure is performed in two stages. First, the application firmware is uploaded
into the converter internal flash. During this stage, the converter checks the firmware
checksum and whether it can be programmed into the unit.
Then, upon the user confirmation, the firmware is programmed into the microcontroller and the
unit is restarted. At the end of this process, the user should see the new firmware version
number on the converter home page in the browser.
The details of the firmware update are provided below.
5.1 Uploading the New Firmware
To upload the new firmware, the user should activate the
Firmware Uploading
page, Figure 17,
by clicking on the
Firmware
link on the left side of the web page.

Then the user selects the new firmware file using the
Brows
e…
button.
The firmware file is provided by Axiomatic in a proprietary binary format with extension:
.af
.
The file name should have the following format:
AF-21153-X.XX.af
, where the
<X.XX>
field
wildcard reflects the firmware version number. We will use
AF-21153-1.00.af
file for
illustration of the firmware update process in this manual.
When the file is selected, the user should press the
Upload
button. The user will see the
dynamic message:
“Loading…” in the bottom of the screen and then, if everything is in order,
the converter will switch automatically to the
Firmware Update
page.
5.2 Applying the New Firmware
