Use the COUNTER button to set TC display.
Turn the POWER/MODE switch to ON.

To externally lock the time code

Follow the steps below.

1

2 Set TCG on the setting menu RECORDING SETUP screen to FREE RUN.

3

4 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.

“Time data overview” (Page 61) · “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.
