It is possible to lock this unit to an external time code
generator, or alternatively to lock an external device to
the time code generator in this unit.
• Once the unit is locked to an external time code, color
framing is disabled. To apply the color frame lock,
first switch the F-RUN/R-RUN switch to R-RUN,
then return it to the F-RUN position.
For an explanation of the color frame lock, see the
footnote on page 2-4.
Locking this unit to an external time code
1 Turn the POWER switch off.
2 Connect the time code output from the external
device to the TC IN connector of this unit, and the
video output to the VIDEO IN connector.
See the connections for the first DVW-250/250P in
the figure "Example connections for time code
locking" (page 4-12).
3 Set the F-RUN/R-RUN switch on this unit to F-
RUN.
This locks the time code generator in this unit to
the external time code signal.
Once the time code generator has been locked, the
time code continues in sync even if the signal is
disconnected from the TC IN connector. In this
case the accuracy of time code synchronization is
determined by the accuracy of the generator of the
sync signal for the input video signal. If the signal
is then disconnected from the VIDEO IN
connector, the accuracy is that of the internal time
code generator.
Notes on external locking of the time code
generator
• The effect of carrying out steps 2 and 3 of the above
procedure with the POWER switch on and a cassette
loaded depends on the setting of the MODE switch,
as follows:
SAVE: The external lock applies when the tape
transport is stopped, recording is paused, and
during recording.
PB/EE or PB: The external lock applies only during
recording. To apply the external lock at other
times, either carry out step 1 above, or press the
REC button, putting the unit into E-E mode.
Locking the user bit value to an external
signal
First lock the unit to an external time code source, then
set the EXT-LOCK/U-BIT switch to ON. This locks
the user bit values on this unit to the user bit values
included in the external time code.
When the EXT-LOCK/U-BIT switch is set to OFF, the
user bit values are not affected by the external signal.
Settings for the output from the TC OUT
Connector
The following setup menu items affect the output from
the TC OUT connector.
For details of setup menu operations, see Section 6-3 "Setup
Menu Settings, "
"TC OUT" item
This selects either of the following as the output from
the TC OUT connector:
GEN: the signal output by the time code generator
AUTO: the signal output by the time code generator
during recording or in E-E mode, and the LTC
signal from the tape during playback
"TC DELAY" item
This selects the LTC phase correction for the output
from the TC OUT connector as follows:
OFF: the signal selected by the "TC OUT" item
without correction
AUTO: the LTC signal adjusted to correspond to the
video output
