Setting the time data (continued)

Externally locking the time code

1 Set the POWER switch to ON.

2 Set the TCG switch to F-RUN.

3 Set the DISPLAY switch to TC.

4 Supply the reference time code and reference video signal which are in a phase relationship that satisfies the time code standard to the TC IN connector and GENLOCK IN connector respectively.

Example of connections for external lock

The time code generator of the VTR unit can be locked to an external generator.

When locking to an external signal

<Note>

When the external lock operation is performed, the time code is instantly locked to the external time code, and the same value as the external code value appears on the counter display.

Do not set the unit to the recording mode during the few seconds it takes for the sync generator to stabilize.

User bits setting when the time code is externally locked

When the time code is externally locked, only the time data is locked to the time data of the external time code.

This means that the user bits can be set separately for each unit.

The user bits can also be locked to the user bits of the external time code. For details, consult your dealer.

To release the external lock

First stop supplying the external time code, and set the TCG switch to R-RUN.

When switching the power from the battery to an external power supply while the time code is externally locked

In order to ensure the continuity of the time code generator’s power, connect the external power supply to the DC IN connector, and then remove the battery pack. If the battery pack is removed first, no guarantees can be made for the continuity of the external locking of the time code.

Gen-locking of the camera unit while the time code is externally locked

While the time code is externally locked, the camera unit is gen-locked by the reference video signal which is supplied to the GEN LOCK IN connector.

<Notes>

O When the frame rate is set to 24 fps, this unit will perform the processing in the non-drop frame mode in order to maintain the continuity of the frames

even when the time code has been set to the drop frame mode.

Furthermore, when the frame frequency has been set to 60.00 Hz as well, the unit performs the processing in the non-drop frame mode.

If an external time code generator is used, set it to the non-drop frame mode.

The built-in time code generator is now locked to the reference time code.

About 10 seconds after locking, the external lock status will be retained even if the connection of the externally supplied reference time code is disconnected. However, the servo lock will be subject to disturbances if it is connected or disconnected during recording (REC).

O Use the same frame frequency setting for the reference time code and reference videos signal as the unit’s setting.

When the frame rate is used at 24 fps, the image may be disturbed if the frame frequencies differ.
