Camera Synchronization

When using one AC power supply in a multi camera system, a brief vertical roll may occur on the monitor each time a camera view is switched. To eliminate vertical roll adjust the phase control to synchronize (line-lock), the cameras to one another. The synchronization switch (DIP switch 10) for each camera must be set to LL. Use the potentiometer located on the side of the camera to make adjustments

It may be necessary to have two people in communication when synchronizing the cameras: one person at the camera and another person at the monitor to observe the vertical roll and the effect of any adjustments made at the camera.

To synchronize the cameras do the following:

1.Choose a reference camera to which all other cameras will be phased.

2.Select a camera and synchronize it to the reference camera by turning the phase adjustment control clock- wise and/or counterclockwise.

3.Each time an adjustment is made, switch back and forth between the camera you are adjusting and the refer- ence camera. Repeat this process as many times as necessary, until the roll between the cameras is no longer noticeable.

4.Adjust the phase of all other cameras by repeating steps 2 through 3. Always adjust to the reference camera selected in step 1.

NOTE: The preferred method for camera phase adjustment is to use a dual trace oscilloscope to align the vertical sync pulses of the reference camera to the selected camera(s).
