External Synchronization
When shooting using multiple camcorder units,
the camcorders can be synchronized to a specific
reference signal or timecodes synchronized via
the Genlock connector of the XDCA-FS7 units
(page 8) attached to the camcorders.
[Note]
The camcorder battery pack cannot be used when an XDCA-
FS7 unit is attached to the camcorder. You must attach a
battery pack to the XDCA-FS7 or connect an external power
supply.
Synchronizing the Phase of the Video
Signals (Genlock)
Enable genlock by supplying a reference signal
to the GENLOCK IN connector (page 8) of the
XDCA-FS7 units connected to the camcorders.
The reference signals that can be used vary
depending on the frame rate of the selected
recording format.

[Notes]
ˎ
ˎ
If the selected recording format is 1280×720 60P, you
must supply both a video signal and a time signal.
ˎ
ˎ
If the reference signal is unstable, genlock cannot be
achieved.
ˎ
ˎ
The subcarrier is not synchronized.
Locking the Timecode to Other
Devices
Set the unit that supplies the timecode to a mode
in which the timecode output keeps running (such
as Free Run or Clock).
1
Set Timecode (page 64) in the TC/UB menu
as follows.
Mode: Preset
Run: Free Run
2
Press the assignable button (page 36)
assigned with the DURATION/TC/UBIT function
to display the timecode on the screen.
3
Check that the TC IN/OUT switch (page 8)
on the XDCA-FS7 is set to the IN position, and
supply an HD or SD reference video signal and
a timecode synchronized to the video signal to
the Genlock and TC IN/OUT connectors,
respectively.
The timecode generator of the camcorder acquires
lock with the reference timecode, and “EXT-LK”
appears on the screen.
Once about ten seconds have elapsed after
the timecode locks, the external lock state
is maintained even if the external reference
timecode source is disconnected.
[Notes]
ˎ
ˎ
Check that the supplied reference timecode and the
reference video signal are in a phase relationship that
complies with the SMPTE timecode standard.
ˎ
ˎ
When operating with external lock, the timecode instantly
acquires lock with the external timecode and the external
timecode value appears in the data display area. However,
do not start recording immediately. Wait for a few
seconds until the timecode generator stabilizes before
recording.
ˎ
ˎ
If the frequency of the reference video signal and the
frame frequency on the camcorder are not the same, lock
cannot be acquired and the camcorder will not operate
properly. If this occurs, the timecode will not acquire
successful lock with the external timecode.
ˎ
ˎ
If the external timecode source is disconnected, the
timecode may shift by one frame per hour with respect to
the reference timecode.
To release external lock
Change the Timecode setting in the TC/UB menu,
or turn the camcorder off.
External lock is also released if you start recording
in Slow & Quick Motion mode.
Synchronizing the Timecode of
Another Device with the Timecode of
the Camcorder
Set the unit that supplies the timecode to a mode
in which the timecode output keeps running (such
as Free Run or Clock).
1
Set the timecode of the camcorder using
Timecode (page 64) in the TC/UB menu.
2
Check that the TC IN/OUT switch (page 8)
of the XDCA-FS7 is set to the OUT position,
and connect the TC IN/OUT connector and
GENLOCK IN connector (page 8) to the
timecode input and reference signal input,
respectively, of the device you want to
synchronize.
