13.5 Resetting the eWON
13.5.1 Overview
In some situation it may be desired or required to initialize the eWON.
The eWON has a non volatile memory which is used to store configurations and acquired data.
Non volatile information is basically divided into 2 groups:
• Communication configuration
• The rest of the non volatile data (file system, Tag Config, user defined web site, etc.)
The reset button is located between the SERIAL and LINE connectors.
A very small hole is located in the box; you will need a thin tool like a paper clip to push the button.
The button must be pressed while the eWON is powered up.
The button must be maintained until correct initialization level has been reached (see below):

13.5.2 Reset sequence
There are 2 initialization levels:
• The first level (the more usual) will force a format of the eWON.
• The second level will reset the eWON in a state corresponding to the "out of the box" configuration. By doing this you will also
perform a thorough self test of the eWON.
13.5.2.1 First level reset
When the eWON boots with the SW switch pressed, after 4 seconds, the "USER" led will start blinking at a 1 flash per second rate.
As soon as the led starts blinking at that rate, release the switch. The Format request will be set.
The blinking will continue during 15 seconds, so there is no need to hurry, but you must release the switch before the 15 seconds elapse.
13.5.2.2 Second level reset
If the SW switch is maintained for more than 15 seconds after blinking starts, the "USER" led will stop blinking and will become "solid red",
at that moment the "Out of the box reset" is registered, the SW switch can be released and all the data of the eWON will be erased,
including its communication, IP address,… parameters.
The eWON configuration tool eBuddy will be required to define your eWON working IP address.
Note: if you have waited too long and the "USER" led becomes "solid red" while you only needed to format the eWON,
the only solution is to keep the SW switch pressed and remove the eWON power, this will avoid entering the "Full Erase" procedure.
