Status
The Status window is a display-only window that gives you the current information on the network
clock’s display and synchronization activity. The status window shows a snapshot of the network
clock display. This status update is not precise, but is meant to give you a view of the clock display
for troubleshooting and maintenance purposes. The Status also shows the active NTP server –
Primary or Secondary, the current synchronization status, and Time Adjustment information.
Time Adjustments may be caused by
o loss of NTP,
o changing the NTP source, or
o changing Network Configuration settings
o power loss or cycling
The Ceiling Exceeded field describes the event where the time adjustment exceeded a value that
will be set in the NTP Digital Clock Configuration - Advanced – Ceiling. Note: the statistics will
reset if you change the NTP server.
[Troubleshooting Tip: In addition to the standard status indications, the network clock will display a
special error indicator under the status window if either a DHCP server cannot be located, or if the
device has an IP address conflict due to either DHCP or Static IP addressing. Under these conditions
the unit will also be assigned a fallback IP address of 169.254.xxx.xxx, and appear in RED text under
the main WinDiscovery window. To determine the cause of why the clock received a 169.254.xxx.xxx
address the user should display the status of the clock. Near the bottom of the Status window the error
will be displayed. (If there is no error the error text field will not be displayed]
