5. Troubleshooting
5.1. Normal Boot Process
The normal boot process of the eWON COSY takes approximately 25 seconds to complete.
During this process, all LEDs are first shortly ON (except BI1) then only the
PWR
LED stays solid
green.
As soon as the boot process is finished and the unit is ready to be used, the
USR
LED flashes
GREEN slowly whereas others might be solid green (if you are connected to Internet, Talk2M,
...).
5.2. Resetting the eWON COSY 131
The reset button B1 is located on the front of the COSY unit (see in
3.3.1.Front
). The reset
function of this button is active only if pressed while powering on.
The eWON COSY features two levels of reset:
5.2.1. First Level Reset (user reset)
The first level reset is a selective one that erases the «
user files
» part and the system settings.
This type of reset does not alter the communication parameters of the eWON COSY.
How to perform a first level reset?
•
Power the unit OFF.
•
While powering it ON, press & maintain the reset button.
The LED labeled BI1 turns ON.
•
Keep the reset button pressed for approximately 30 seconds until the
USR
LED flashes
RED 1x per second. If you don't release at that specific moment, you will perform a
second level reset phase.
The LED labeled BI1 turns OFF.
•
Wait approximately 30 secs until the reset process is completed.
•
The eWON restarts automatically and the unit is ready to be used, the
USR
LED flashes
GREEN slowly.
5.2.2. Second Level Reset (factory reset)
This second level reset restores the eWON to its factory settings. This operation consists in 3
steps:
•
Formats the entire non volatile memory, including all COM parameters and IP
addresses
•
Full hardware auto-test with result shown by the
USR
LED
