Adjustments and Settings for Recording : Setting Time Data
Adjustments and Settings for Recording
Follow the steps below.
1 Turn on the POWER switch.
2 Position the TCG switch at [F-RUN].
3 Position the DISPLAY switch at [TC].
4 Set the menu option GENLOCK to “EXT”.
This option can be found in the <GENLOCK> screen,
which is accessible from the SYSTEM SETTING
page.
5 Supply a phase-relationship reference time code (that
conforms to the time code requirements) and
reference video signals to the TC IN and GENLOCK
IN connectors, respectively.
Now the built-in time code generator is locked with the
reference time code.
From about 10 seconds after locking the time code
generator stays locked even if the supply of external
reference time code is discontinued.
Notes
z When the time code generator is externally locked, the
time code instantly becomes locked with the external
time code, and the counter displays the external time
code value. Do not put the unit in recording mode before
the sync generator stabilises.
z Be sure to enter the non-drop-frame time code to
externally lock the time code in the 24P or 24PA mode.
Externally locking the drop-frame time code is not
permitted.
Video quality may be degraded momentarily while
externally locking to adjust the 5-frame cycle. This is not
abnormal.
z When the IEEE1394 interface board (AJ-YAD800G,
optional) is attached, it is not possible to synchronize
with the time code entered via the TC IN connector if
“1394” is selected for the menu option REC SIGNAL.
The menu option REC SIGNAL is found in the SYSTEM
MODE screen on the SYSTEM SETTING page.
When the TCG switch is positioned to F-RUN, only the
time code is locked to an external time code. To lock the
user bits to an externally input value, the UB MODE and
VITC UB MODE menu options must be set to EXT and
USER EXIT, respectively.
The menu option UB MODE and VITC UB MODE can be
found in the <TC/UB> screen, which is accessible from the
MAIN OPERATION page.
Discontinue external time code supply, then position the
TCG switch at [R-RUN].
Connect the DC IN socket with the external power supply
before removing the battery pack, in order to keep the time
code generator energised. If the battery pack is removed
first, there is no guarantee that the time code will stay
externally locked.
When the time code is externally locked, the reference
video signals input through the GENLOCK IN connector
gen-lock the camera.
Notes
z To externally lock the unit, as the master device, with
more than one unit, the mode must be the same as that
of the camera. Note that in a system using both
interlaced and progressive scanning, there may be
breaks in the video and time code.
z When using the MON OUT or VIDEO OUT connector to
output reference signals, position the OUTPUT SEL
switch on the side panel at [CAM].
