Control 4.5.3.2.1
LEAP YEAR
Leap year programming (365 or 366 days). Select Yes or No (ensure the external
time code generator setting is identical).
CURRENT OFFSET
Configuration parameter and status. Allows to enter a time offset for immediate
application and to read the current time offset. Expressed in seconds (signed
value).
The current time offset is added to the time delivered by the internal Time Code
Reader, for time tagging telemetry frames, range measurements, etc...
DATE OF NEXT
OFFSET 1
At this date, Next Offset 1 will replace the current offset. Expressed in seconds
with January 1
st
00:00:00 = 0.
NEXT OFFSET 1
This time offset, expressed in seconds (signed value), will become effective when
the current date matches Date of Next Offset 1. See note 1.
DATE OF NEXT
OFFSET 2
At this date, Next Offset 2 will replace the current offset. Expressed in seconds
with January 1
st
00:00:00 = 0.
NEXT OFFSET 2
This time offset, expressed in seconds (signed value), will become effective when
the current date matches Date of Next Offset 2. See note 1.
Note that if Date of Next Offset 1 = Date of Next Offset 2, then Date of Next
Offset 2 will be ignored (no offset update: priority to Offset 1).
TIME CODE
Expected time code (IRIG-B or NASA-36) or NTP if expected time from an
external NTP server (refer to § 4.4.3.2.3)
Note 1: At boot up, the current offset value is set to the latest value programmed by the Operator
(automatic adjustment of Current Offset from Next Offset 1 or Next Offset 2 is not memorized by the
machine).
Monitoring 4.5.3.2.2
TIME-TAG CODING
Time-tag coding in TCP-IP messages:
Code 3
Time-tags are expressed in seconds and microseconds of the
second (integer format).
DECODER STATUS
Time Code Reader status: Locked or Unlocked or Flywheel.
NTP cilent set-up 4.5.3.2.3
The HDR is fitted with an NTP client. The activation of the NTP client is done by setting the parameter
“TIME CODE” to “NTP”.
Two parameters are available for the set-up: the address of the server and the time refresh period
(Server name or IP address, Adjustment period in seconds). The time is periodically updated when
the HDR is set in Configuration mode.
These set-up parameters are not directly accessible through the GUI. The setup is done using the tool
“uihm.exe”. This tool is available in the directory C:\Program Files\ZDS\uihm for Windows 7
otherwise C:\Program Files\IN-SNEC\uihm.
