13.6 The eWON firmware upgrade process
13.6.1 Overview of the upgrade process
Very important notes:
Applying a new firmware on the eWON requires following a very precise process that is described in chapter “eWON firmware
upgrade step-by-step” on page 231.
Please do not attempt to upgrade your eWON prior reading this chapter if you are not so familiar with this process,
otherwise you could severely damage your eWON.
Versions 4.xx apply to eWON 500, 2001, 4001 and 4002. That means, NOT TO eWONs 1000, 2000 and 4000.
It is possible to come back to version 3 after you have installed the firmware version 4 on your eWON, providing you apply a level 2
reset to your eWON prior to “downgrading” it to version 3.
The choice of the firmware you will install on your eWON depends on the current version your eWON embeds:
• If your eWON is still running a version 3 firmware, you should use the firmware that permits you to upgrade from v3 to v4.
• In case you are already running a version 4, and that you want:
• either upgrade from your current v4 version to the latest version
• or reapply your current firmware, because you think that your eWON requires such an operation,
Then you should use a v4 to v4 firmware.
All the V4 firmwares are available for download from http://www.ewon.biz/
(Support/Download software), depending:
• On your eWON's P-Code (86, 87, 88 or 89),
• On the firmware version your eWON is currently running (V3.8 or V4.xx).
Note:
You can always check your eWON's current version, by clicking on the eWON logo that is available from any standard eWON's
website page (at the top left corner, as illustrated on the screenshot below)
• On the language with which you want to monitor your eWON (English or French).
