The FREE Mode of the Time Code Generator
Switching on the FREE method of operating can be done utilizing a function key or GPIO
assigned with the
Operating Mode Free
function or clicking button
FREE
at the
Generate
page of the configuration tool.
The FREE method of operating has been provided to add a feature to the REAL
–
TIME mode.
With FREE it is possible to shift a legal time jump in the time code according to a DST
switching or a leap second to a user defined moment.
During REAL
–
TIME mode these time jumps occur automatically. There may be other devices in
the system depending on a continuous time code. With just one press to a button you can
avoid this time jump and allow it later at a suitable moment:
•
Switch from REAL
–
TIME to FREE before the time jump event
–
the time code counts
continuously without any frame discontinuity.
•
Switch from FREE to REAL
–
TIME after the time jump event at a suitable moment. This
forces the time code to update with the real
–
time reference, now the time code
transports the precise local time again.

Switching between REAL
–
TIME and FREE becomes
very easy if you program two of the function keys
appropriately.
The lamps of the keys give a feedback about the
currently selected operating mode.
