(7) Setting monitor synchronization
(24 VAC adaptor users)
The camera offers V-phase adjustment over 360°. Vertical sync disturbance may occur
when a switcher is used to switch between multiple cameras connected to one monitor.
To prevent vertical sync disturbance, adjust (7) by pushing the button. Before making any
adjustment, confirm that the cameras are connected to the power supply with the same
polarity. To make an adjustment:
While observing the video outputs from the cameras on an oscilloscope, press
the the first camera's V-phase pushbutton. Until vertical sync from all cameras are
in phase. If the first camera's adjustment phase is insufficient, adjust the second
camera's V-phase contol in the oppposite direction until they are in phase.
CAUTION
When using the 12 VDC adaptor, sync setting is set to internal sync.
NOTE: Sync is selected by a switch on the camera board, Int or L/L (Line Lock).
