This unit supports the following 3 types of synchronization methods, and one of the following is selected.
(1) Multiplexed ver tical drive signal (VD2)
(2) Synchronization is perfor med on the basis of the power supply frequency.
(3) Inter nal synchronization (INT) (default)
Input of a multiplexed vertical drive signal (VD2) automatically switches to the VD2 synchronization even if the camera is set to
other than the VD2 synchronization method.
When other than the VD2 synchronization is selected, either the power supply synchronization or internal synchronization can be
selected.
