4.3.5 Clock Setup section
Figure 18: eWON clock setup field
The eWON’s real time clock can be updated manually with this dialog window.
Fill in the edit box with date and time and click on Update Clock button.
An event will be added to the event log signaling the time update and the time offset between old and new time.
Important: Updating the time may result in duplicate points stored in non-chronological order in the eWON files
(alarms, events and historical).
4.3.6 COM Setup section
Warning: depending on eWON's version (c.f. Table on page 233)
The third page of the System setup is the communication setup. All Ethernet, modem and PPP TCP/IP connectivity parameters are defined
here. This page is divided into 7 sub-menus, which classifies the COM setup into functional systems:
Ethernet, Modem, Dialup (PPP), Callback, Router (Filter), IP Services and Default Config (Communication setup only).

• Important: This configuration is not saved in the eWON flash file system, its means that formatting the eWON will not erase this
configuration. This allows formatting the eWON remotely and ensuring that communication is still possible after formatting.
Nevertheless, the Default Config menu allows the user to return to default well known communication values.
