LINE SYNCHRONIZATION
If cameras are out of phase with each other, they may produce what appears to be vertical roll when switching between cameras.
There are two settings for line synchronization:
ON – Adjust the synchronization of the power line voltage so that it is in phase with other cameras.
OFF – The system synchronizes to an internal clock.
To change the line synchronization settings:
1. Program preset 95 (28). The main menu appears.
2. Position the cursor (>) beside Line Sync.
3. Press the Iris Open button. The Line Sync menu appears.
4. Position the cursor (>) beside one of the choices. Press the Iris Open button.
LINE SYNC – The cursor moves to one of two choices: ON or OFF. Move the joystick up or down to toggle between them. Press the Iris
Open button to select the choice. If you changed to OFF, the camera may reset itself as it adjusts to the new synchronization. If the camera
resets, it will only affect the line synchronization. It will not change any other camera parameters, such as auto focus or auto iris. Press
the Iris Close button if you do not want to change the setting.
LINE SYNC PHASE – The cursor moves to a numeric value. Move the joystick up or down to change the value. The value represents the
phase angle in tenths of a degree between 0 and 359 degrees. For example, 900 is 90 degrees, 1200 is 120 degrees, and 2400 is
240 degrees. Press the Iris Open button on your keyboard to select your choice. The Line Sync setting changes to ON. The camera may
reset or the picture on your monitor may wiggle when you change the phase angle. If the camera resets, it will only affect the line
synchronization. It will not change any other camera parameters, such as auto focus or auto iris. Press the Iris Close button if you do not
want to change the setting.
