Externally Locking The Time Code - Panasonic AJ-HPX2000 Operating Instructions Manual

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.

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 either the
HDY output signals of the MON OUT connector or VBS
output signals of the VIDEO OUT and 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.
