6.1 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 propelling pencil or an unfold paper clip to pass through the hole
in the front panel.
6.1.1 User Reset
This is the first level and most usual level of reset. 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 in red 1x per second. When this state is
reached, release the button and wait approximatively 30 secs until the procedure is completed. The eWON
restarts automatically and is ready to communicate. This type of reset does not modify the communication
parameters.
6.1.2 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
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 90 seconds until the procedure is completed. The
procedure finishes with the result of the autotest on the “USER” LED. If the autotest is completed succesfully,
then the “USER” LED will blink in RED with a pattern of 200ms ON and 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 before, the
eWON returns to its default COM parameters and IP addresses after this level 2 reset is performed.
