8.1 Resets
Warning: you should not reset your eWON® unless you have been told to do so by someone of our
technical support. The concerned files (differs depending on reset type) are totally lost and
unrecoverable after being formatted.
To press the reset button, you will need a standard ball pen to pass through the hole in the front panel.
8.1.1 User Reset
This is the first and most usual reset level. It consists in formatting only the « user file » part of the non volatile
memory. The Tag configuration and the customer web site are part of the formatted files.
You generate this first level reset by pressing and maintaining the reset button during approximately 4 seconds after
powering the eWON® up until the “USER” LED flashes 1x per second. When this state is reached, release the
button and wait approximatively during 20 secs until the procedure is complete. The eWON® restarts automatically
and is ready to communicate. This type of reset does not modify the communication parameters.
8.1.2 Factory Reset
This second level reset is used only exceptionally because it formats all non volatile memories and make the
eWON® returning to its factory defaults. This operation consists in 3 stages:
• Formatting of all non volatile memories, including all COM parameters and IP addresses
• Return to ex-factory configuration (default config)
• Full hardware auto test with result shown by the “USER” LED
Warning: you should not reset your eWON® unless you have been told to do so by someone of our
technical support. The concerned files (differs depending on reset type) are totally lost and
unrecoverable after being formatted.
You generate this second level reset by pressing and maintaining the reset button during approximately 20 secs
after powering up the eWON® until the “USER” LED remains RED continuously. When this state is reached, release
the button and wait approximatively during 45 secs until the procedure is complete. The procedure finishes with the
result of the autotest on the “USER” LED. If the autotest is completed successfully, then the “USER” LED shows its
normal pattern of 200ms ON et 1,5 sec OFF.
Any other pattern will start with 200ms ON (opening of the pattern) followed by OFF and a certain number of times 1
sec ON that allows to identify the nature of the detected problem. Please call the technical support if you are
confronted with an error pattern on the “USER” LED.
Warning: you absolutely have to wait until the full autotest procedure is completed without interrupting
it. If the autotest is interrupted, the flash memory of the eWON® will contain random data likely
to make it unstable. In such a case you have to redo the full reset procedure from scratch and
wait until it is totally completed.
When performing a full reset, the eWON® does NOT restart in normal mode by itself and remains running in
diagnose mode. Power the eWON® off and on again to restart in normal mode. As described previously, the
eWON® returns to its default COM parameters and IP addresses after this level 2 reset is performed.
