Line-Lock control
●
Matching the vertical synchronization with the power frequency is called the Line-Lock.
●
This function is activated when the LL switch is set to ON.
LL switch
●
When two or more cameras are switched by video switcher for viewing by a monitor TV,
the vertical sync. phase can be locked with the power frequency, and a stable vertical
sync. is obtained without being disturbed at the time of switching.

CAMERA2
If two or more cameras within a system have
different AC line phases are switched by the video
switcher, the picture on the monitor TV will fluctuate
vertically.
Connect 24V AC input line of all cameras so that
they all share the same phase.
If you still have vertical fluctuation, adjust the
V.PHASE controller.
NOTE
●
The camera is synchronized to the power frequency of 60
±
1 Hz covering a normal
fluctuation of the power frequency. However, the camera may not cover a large
fluctuation caused from the power generated by an engine generator, etc.
●
It takes about 10 seconds or more until a stable synchronization is obtained after the
power is turned on. This is normal, because several seconds are required to stabilize
the camera against power noise.
