NTP Setup
The NTP Setup screen is used to control how the real-time clock/calendar of the CX-6p-
PoE 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 CX-6p-PoE 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 CX-6p-PoE 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 CX-6p-PoE 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.
