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>
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-SPX800P in recording mode before the sync
generator stabilises.
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.
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.
<Notes>
To externally lock the AJ-SPX800P, 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.
When using the MON OUT connector to output reference
signals, position the OUTPUT SEL switch on the side panel at
[CAM].
