CHAPTER 12: USING THE D400 LOCAL CONFIGURATION UTILITY
Configure time and time synchronization
The
Configure Time Synchronization
menu allows you set the D400's internal date
and time as well as modify options associated with time synchronization. The Time and
Time Synchronization settings are described in Table 37.
Table 37: Time and Time Synchronization setting descriptions
Reset system logs

Setting Description
Show Time and Current
Settings
Use this function to display the time, time zone, and synchronization
settings currently configured.
Set System Clock Use this function to configure the current calendar date and time of
day.
Note : The D400 system time is automatically set to the firmware
build time whenever the D400 reboots and the system time is less
than the firmware build time.
Set Time Zone Use this function to enter the time zone of the D400.
Note : The D400 uses the IEEE POSIX® standard for time zone
naming. POSIX uses the time zone offset to get GMT from the local
time (that is, GMT - local time) instead of the more common format
(local time - GMT). For example, Eastern Standard Time in North
America, which is 5 hours behind GMT, is listed as “GMT+5”, and not
“GMT-5”.
Time Sync Input Configures the D400 to use either IRIG-B or NTP to calibrate the
system clock.
•
IRIG-B: Enter the IRIG-B format, options are TTL (pulse width
code), Sine wave (amplitude modulated), and Manchester.
Ensure SW2 of the IRIG-B Input Adapter is configured for the
proper input type: Fiber Optic or TTL for TTL and Manchester,
BNC for Sine wave.
• NTP: Enter the IP address of the NTP server. The D400 verifies if
the source is accessible by pinging the address.
When configuring a D.20 RIO, refer to the D.20 RIO Hardware User's
Manual (994-0141) section: Time Synchronization Strategies.
Time Sync Output Use this function to configure the D400 to operate as an NTP time
server.
Setting Description
Check Size of Archived Logs Active system logs are automatically archived when they reach a
size of 256 KB. Up to 10 archives are kept within the D400, with
newer logs overwriting older stored logs. Check Size of Archived Logs
lets you view the amount of disk space occupied by these archived
log files. The value is shown in KB.
Check Size of Current
Application Logs
Use this function to view the amount of disk space occupied by the
current application logs. The value is shown in KB.
Delete Archived Logs Use this function to permanently delete archived logs from the D400.
Delete Current Logs Use this function to permanently delete current application logs
