NTP Setup
The NTP Setup screen is used to control how the real-time clock/calendar of the N-111
is updated. The user can select one of three update modes: No updates, NTP
broadcast updates, or polling a NTP server.
If “None” is selected for the NTP update mode, the N-111 will never update its real-time
clock/calendar. If the time was set accurately before updating was disabled and a
working battery is installed it should retain a fairly accurate time and date for some time.
There will be some drift from true time and date over time, so this mode is not
recommended.
If “Accept NTP Broadcast” is selected, the N-111 will update its time and date settings
every time it received a NTP broadcast packet on the network. This is the default
setting.
If “Poll NTP Server” is selected, the N-111 will periodically connect to a NTP server to
update its RTC setting. No server is specified by default, so if the user wishes to use
this function they will have to specify a server address. The time between updates can
be set. The default setting for update rate is to update once every 12 hours.
