Using time data (continued)

To externally lock the time code

Follow the steps below.

Turn the POWER/MODE switch to ON.

Set TCG on the setting menu RECORDING

SETUP screen to FREE RUN.

Use the COUNTER button to set TC display.

Supply a phase-relationship reference

time code (that conforms to the time

code requirements) and reference video

signals to the TC IN/OUT and GENLOCK IN

connectors, respectively.

• Now the built-in time code generator is locked to

the reference time code.

• When locked to an external time code generator,

the time code is at all times locked to the external
time code, which is displayed as a highlighted
value on the counter indicator. Do not engage the
recording mode during the few seconds it takes
for the sync generator to stabilize.

• Once a slave relationship is established, the TC

IN/OUT and GENLOCK IN connectors stay in
slave status.*

· When TC PRESET is performed.
· When the REC SIGNAL option in the SYSTEM

SETUP screen is set to 1394.

· The power is turned off.
· The time code mode is switched.
· The TCG switch is set to R-RUN.
· When REC FORMAT and CAMERA MODE

have been switched.
* The slave function is a state whereby the

unit’s internal time code generator is locked
to and progresses with an externally input
time code, and continues to progress after
input of the external time code has stopped.

Setting the user bits when the time code is

externally locked

To externally lock user bits, set the setting menu
UB MODE (RECORDING SETUP screen) to EXT.
Regardless of an FREE RUN or REC RUN setting,
the time code is slaved to user bit values input to
the TC IN/OUT connector.

“Setting user bits” (Page 62)

To unlock the externally locked time code

Discontinue external time code supply, then set the
setting menu TCG (RECORDING SETUP screen)
to REC RUN.

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.

•

To lock other devices externally to the AG-

HPX250P/EN, as the master device, make

sure that the other devices are in the same

camera mode as the AG-HPX250P/EN. Note

that if some of the connected devices use

interlaced scanning while other devices use

progressive scanning, there may be breaks

in the video and time code.

•

When 24P, 24PA or 24PN (native) is selected

and the time code is externally locked, be

sure to select a non-drop frame time code.

The time code cannot be externally locked

when drop frame mode is selected. When

the time code is externally locked, the

video may be distorted, but this is because

of adjustment to 5-frame segments and not

a malfunction.
