Operating Manual
Rev. 0.2 - Updated September 26, 2005
6. Vertical Reset Operations
In this “Vertical Reset Mode”, when the camera receives one VD pulse,
only one field of video signal (2:1 Interlace mode) or one frame of video
signal (progressive mode) is sent out.
1)
Turn “Sync Mode Switch” (2.b) to “External Sync”
2)
Turn DIP switch No. 2 (2:C:II) to “ON (Internal or External Sync)”. The
camera switches to external mode automatically when external HD is
supplied.
3)
The vertical operates as “Direct Reset Mode”
4)
In the case of 2:1 Interlace, even odd field is determined by the timing
of the falling edge of the vertical reset pulse (see note on next page)
