Time Zone
This field shows the offset from UTC and is only valid when the Time Mode is
Offset
Local. A positive Time Zone Offset implies a longitude east of the Greenwich
meridian. To change the time zone use the
systimemodeconfig
command.
Daylight Saving
This field will show whether DST control is enabled or not.
Time
DST fields are only used when the Time Mode is Local.
DST Start,
These fields will only display if the Daylight Saving Time field above shows
DST End
enabled. If enabled, then these fields show when DST starts and ends during the
year. For example, in most of the U.S.A. the DST Start Time is the 2nd Sunday
in March at 2 a.m. The DST End Time is the 1st Sunday in November at 2
a.m. DST settings are used when the time mode is Local. To change the DST
settings use the
systimemodeconfig
command.
I/O Page
This page shows the CPU Module outputs and their settings. The standard outputs are the 1 PPS and
Time Code (AM). There may also be one optional output for the 1U chassis, or four optional outputs
for the 2U chassis. Use commands
cpuoptsconfig
and
sysioconfig
via the console port to
change the settings of the CPU Module outputs. See
Chapter 10 - Rear-Panel I/O
for information on
the various options.
I/O Page (Plug-In Options)
This page shows any installed Plug-In Modules and their settings. Some plug-in modules can be
user-configured. Use command
pluginoptsconfig
to change the configuration of these modules.
Faults: System Faults Page
This page lists all possible system fault conditions of Meridian II - the Linux Subsystem, the GPS
Subsystem and the GPS Receiver. For details on each fault see
Appendix G - System Faults
.
Faults: Fault Mask Page
Fault Masks
Signal Fault
This field shows the current mask setting for the Signal Fault, either Masked or
Enabled. When the signal fault is Masked it will prevent a Signal Loss Fault
from occurring. Some installations may need to mask this fault when operating
Meridian II with no GPS signal. (An example of this would be when
configured as a Stratum 2 NTP Server.) To change the Signal Fault Mask use
the
setsigfltmask
command, or the front-panel keypad/display.
Antenna Fault
This field shows the current mask setting for the Antenna Fault. When the
antenna fault is Masked it will prevent an Antenna Fault from occurring.
Some installations may need to mask this fault due to special antenna situations
like splitters. To change the Antenna Fault Mask use the
setantfltmask
command, or the front-panel keypad/display.
