Keypad/Display Interface
n
Small date and time, reference, and NTP stratum.
The time display also indicates a time scale:
n
If the time zone setting on TIMING - Time Zone page is set to UTC, the time display shows
"UTC" as the time scale.
n
If the time zone setting on TIMING - Time Zone page is set to a non-UTC (local) time zone,
the time adds AM/PM.
n
If the Ignore UTC Corrections from GPS Reference setting on the TIMING - HW Clock page
is enabled (selected), the time display shows "GPS" as the time scale.
Note: The TIMING - Time Zone page configures the display for UTC or local time. The TIMING -
HW Clock can be used to display GPS time (not recommended). Also see TIMING - Time
Zone (on page 42) and TIMING - HW Clock.
STATUS Button
Pressing the STATUS button repeatedly displays a series of status screens for:
n
NTP
n
Alarms
n
Network Ports
n
Hardware Clock
n
GPS Receiver
n
SyncServer model, serial number, software version, and software upgrade availability.
The upper right corner of each screen displays the user-configured UTC, local, or GPS time.
See
TIME Button (on page 73).
NTP Status Screen
Network Time Protocol (NTP) daemon status.
Stratum : The Stratum number of the SyncServer. Stratum 1 means it is locked to a Hardware
Clock Input Reference. Stratum 2-15 means the SyncServer is locked to another NTP time
source. Stratum 16 means that the SyncServer is unsynchronized.
REF : This field identifies the "system peer". While stratum is 16, this field shows the pro-
gression of the NTP clock PLL. The field starts with a value of "INIT". Once a peer has been
selected, the clock may be stepped, in which case the reference ID field changes to "STEP".
Once the PLL is locked, the stratum is updated and the reference ID provides information
about the selected peer. When the SyncServer is operating at stratum 1, the reference ID dis-
plays the name of the Hardware Clock reference input. If the selected peer is another NTP
server, the reference ID displays the address of the server.
NTP Packet I/O: The number of NTP packets the SyncServer has replied to and initiated. The
SyncServer replies to clients that send NTP requests. The SyncServer also sends NTP
requests when the NTP daemon isn't synchronized (i.e., Sync LED is RED) and when it is
configured to synchronize to an NTP association (e.g., a Server type association).
Also see STATUS - NTP (on page 25).
