SOURCE.
Use the left (
◄
) or right (
►
) arrow button to select the timecode
reference.
Internal:
If Internal is selected, then the time can be set manually like setting
any clock.
Press the
ENTER
button, and then use the left (
◄
) or right (
►
) arrow button
to select a digit in the offset value to change. An underline character appears
under the selected offset digit. The date and time digits take the following
form: YYYY-MM-DD HH:MM:SS.
NOTE.
Selecting Internal applies the start time and date. Typically, this causes a
disruption to the syncs, so care should be taken to verify the date and time are
correct before selecting Internal mode.
VITC Input:
Selects the vertical interval time code as the timecode reference.
VITC is only available when the Reference Source is set to a video Genlock
signal.
NOTE.
VITC input is not available on earlier GPS7 modules that do not have
the REF IN input connector.
GPS Signal:
If GPS Signal is selected, the time from the GPS receiver is used
to derive the time of day. This selection is only available if GPS Signal is the
selected Reference Source.
Mode.
When VITC is the Timecode Source, Use the left (
◄
) or right (
►
) arrow
button to select the synchronization mode.
Follow:
The time of day follows the VITC on the input signal if the signal is
stable for at least 100 consecutive frames.
Synchronize Once:
The VITC on the input signal is continuously monitored
until a stable signal is received (at least 100 consecutive frames). At that time,
the time of day synchronizes (once) to this reference.
Synchronize Now:
The time of day attempts to synchronize with the VITC
on the input signal when the ENTER button is pressed. A total of ten attempts
to synchronize are made. After ten attempts, no further attempts are made to
synchronize regardless if synchronization occurred or failed. A stable signal
of at least 100 consecutive frames is needed.
INTERNAL.
After you select an offset digit, use the up (
▲
) or down (
▼
) arrow
button to change the value of the digit. Repeat for each digit as required for
your date and time. Press the
ENTER
to con
fi
rm the change and set the time.
