5.2.1.13.4.1 CONFIG: IP  ANT  SNTP (Simple Network Time Protocol)
SNTP: Disabled (Disabled, Enabled)
Servers: Primary Backup ()
Simple Network Time Protocol (SNTP) is used to synchronize computer clocks throughout a
computer network when the ultimate performance of the full NTP implementation as per
RFC-1305 (Requests for Comment No. 1305: Network Time Protocol, Version 3, Specification,
Implementation and Analysis) is not needed or justified.
On the top line – Use the ▲▼ arrow keys to select SNTP as Enabled or Disabled. If Enabled,
SNTP contacts the time server to update the Real-Time Clock (RTC) every 24 hours. If Disabled,
no such notifications take place.
On the bottom line – Use the ◄ ► arrow keys to first navigate to the bottom line, and then
select the Primary or Backup Server submenu. Pressing ENTER to continue:
[#######] Time Server: 192.168.001.010
Last Update: Never ()
(Where [######] Time Server denotes “Primary Time Server” or “Backup Time Server”):
On the top line – To edit the selected Time Server’s IP Address, use the ◄ ► arrow keys to select
a digit to edit, and then use the ▲▼ arrow keys to change that digit.
On the bottom line – this read-only field displays the time and date that the selected server was
last updated. The time is shown in military format (HH:MM:SS); the date is shown in DAY-
MONTH-YEAR format in accordance with European convention. This line specifies “Never” if no
update information exists.
