Chapter 4 Adjustments and Settings for Recording
(continued)
To externally lock the time code
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 AJ-SPC700P in recording mode
before the sync generator stabilises.
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.
Setting the user bits when the time code is
externally locked
When the time code is externally locked only time data is
locked with the time data of the external time code.
This means that the user bits may be set separately for each
camera-recorder.
When “EXT” is specified for the menu option UB MODE, the
user bits is also locked with the user bits of the external time
code.
The menu option UB MODE can be found in the <TC/UB>
screen, which is accessible from the MAIN OPERATION
page.
To unlock the externally locked time code
Discontinue external time code supply, then position the
TCG switch at [R-RUN].
Cautions in switching the power source from
battery to external power supply
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.
External synchronisation of the camera when the
time code is externally locked
When the time code is externally locked, the reference video
signals input through the GENLOCK IN connector gen-lock
the camera.
<Note>
To externally lock the AJ-SPC700P, 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.
