3. Enter Time and Date parameters and press Save. Press Cancel to discard changes. Please note
that Time and Date cannot be set via this menu if NTP is enabled (see Figure 2.2.39 on page
2.2.64 ).
• Date - select values from the calendar icon for Day, Month, and Year.
• Time - select values from the clock icon for hours (24-hour clock) and minutes (up to 60).
You can click Now to set the clock to the current time.
NOTE
:
Changes cannot be made via this menu if NTP is enabled. Disable NTP, make required changes in
the Time menu then re-enable NTP.
NOTE
:
Ensure the proper Timezone is selected to observe Daylight Savings time (DST).
NTP servers
You can configure an NTP (Network Time Protocol) server to allow clock synchronization with all
computers on the same network as the transmitter.
NOTE
:
The accuracy of the NTP synchronization is related to the distance to the server, therefore Nautel
recommends you choose servers in the same country as the equipment. If this is not possible, attempt
to connect to servers from the same continent.
NOTE
:
The NTP clock synchronization polling interval varies between 64 and 1024 seconds. To minimize
network traffic, the interval will change depending on how much error is accumulated between polling
events and will be increased if the remote NTP server becomes unreachable. The polling interval is also
randomized slightly to avoid the situation where a large number of requests are always arriving at the
NTP server at the same time.
Enabling NTP
Enable the NTP function by moving the NTP toggle switch to the right (displays green). Disable by
moving the NTP toggle switch to the left. When NTP is disabled, the Current Timezone fields (Country
and Zone, as applicable) are also displayed (see
Setting the Clock - Using the AUI on page 2.2.64 ). Click
the Save button to activate any change.
