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 “GL IN” or
“SDI IN”.
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 GENLOCK IN or SDI 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. Additionally, time codes lock on TC IN connector
signals. Time codes of HD SDI signals input from the SDI IN
connector are not locked.
z
Be sure to enter the non-drop-frame time code to externally
lock the time code in the 24P, 24PA or 24PN (Native) 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
While recording data in the 24P, 24PA, or Native modes, it is
impossible to lock the time code externally. Lock it before
recording.
When the unit PRE REC MODE is set to [ON] in these modes,
corrupt images or stopped time codes may be recorded if the
time code is switched from REC RUN to FREE RUN
immediately before recording or when using slave lock.
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.
These menu items are found in the <TC/UB> screen on 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 or SDI 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 this unit’s MON OUT connector and SDI OUT
connector are used as reference video signals, set the
MONITOR OUT MODE menu option or the SDI OUT MODE
menu option to “CAM”. These menu items are found in the
<OUTPUT SEL> screen on the SYSTEM SETTING page.
To display the time code in the viewfinder or the LCD monitor
when recording or during playback, set TC in <VF
INDICATOR3/3> to “TCG”, “TCR”, or “TCG/TCR”.
To display these time code displays in MONITOR OUT and
SDI OUT output, set the MON OUT CHARACTER switch on
the side panel to [ON], set the MONI OUT CHARA menu
option to “ON”, and set the SDI OUT CHARACTER switch to
[ON]. You can select the MONI OUT CHARA menu option
from the <OUTPUT SEL> screen of the SYSTEM SETTING
page.
Additionally, to display time codes while displaying the color
bar, set the TC ON COLOR BAR menu option to “ON”. You
can select the TC ON COLOR BAR menu option from the
<VF INDICATOR> screen of the VF page.
