Externally Locking the Time Code

The unit’s internal time code generator can be locked to an external generator. In addition, the external time code generator can be locked to the unit’s internal generator.

Example of connections for external locking

As the figure shows, connect both the reference video signal and reference time code.

Example 1: When locking onto an external signal

a

TC IN

Note

The system can be configured with multiple units by opening the <GENLOCK> screen from the SYSTEM SETTING page and setting the GL PHASE item to the connector using menu operations.

The phase of the time code can correspond to the VBS output signals of the MON OUT connector.

However, the same value should commonly be set to the GL PHASE for all cameras. If different values coexist in the system, the shooting timing may not correspond to each other.

Note that when the unit is in the 1080-23.98PsF or 1080- 24PsF modes, it is not possible to lock the time code using the VBS connection with one unit as a reference unit in the manner shown in Example 2. When using these modes, connect the unit in the manner shown in Example 4 and Example 6.

Note

In place of the HD Y reference signal, composite video signals can be input as the reference video signal.
