9. TIME CODE OPERATION

9-3 Recording Time Codes by Slave-Locking the Built-in Time Code Generator with External TCG

The built-in time code generator can be synchronized (slave-locked) with the SMPTE-standard LTC time code signal which is input through the TC IN connector. Once the slave locking has been carried out, the built-in time code generator runs even when the external time code input stops. Even when the power is switched off, it continues to run on the backup lithium battery.

GENLOCK/AUX IN connector

1. Input the reference video signal into the external time code generator and the GENLOCK/AUX IN connector of this unit.

Note :

When the power is switched ON while external sync signal is input, the screen moves in a vertical direction for a few seconds. This is not a malfunction.

2. Input the SMPTE standard LTC time code signal into the TC IN connector.

3. Display time code on the counter display.

4. Set the switches in the TC GENERATOR block as follows.

•Set the TC GENE switch to “FREE”.

*While the TC GENE switch is set to “REC” or “REGEN”, slave-locking will not take place.

Set the related VCR Setup Menus.

• Set the VCR Setup Menu item No. 398 SSF MODE to “OFF”.

*If set to CUE mode or MARK mode, the slave-locking will not take place.

•Set the VCR Setup Menu item No. 403 U-BIT SLAVE. Set to “TC&UB” when the user’s bits should also be slave- locked with the external time code generator.

•The framing mode will be the same mode as the automatically entered time code (drop frame of non-drop frame).

During the non-drop frame mode, the NDF indicator will light on the display.

During the drop frame mode, the DF indicator will light on the display.

5. Set and operate the external time code generator.

➡The built-in time code generator is slave-locked with the input external time code data.

The SLAVE indicator lights on the display.

*If the external time code generator phase is not genlocked with the phase of the camera video signals, the “SLAVE” display will flicker.

•Once slave locking has been made, the built-in time code generator keeps on running even when the external time code generator is stopped.

Note :

Do not connect or disconnect slaves during recording as this may disturb the servo lock.

Multi-Camcorder Master-Slave Connection

When there is only one slave GY-DV550, connect it as indicated in the figure below.

When connecting several GY-DV550s as slaves, input the REF video signal to GENLOCK/AUX IN connectors of all these units from the sync signal generator.
