3.1.1 (a) Direct Shutter Control Mode
For Direct Shutter Control Mode, set the dial switch to “E”. When the up/down switch on the back plate
is used, the shutter increments or decrements by 1H from the current setting. By controlling through
RS-232C, the exact shutter speed can be programmed by feeding H number from 1H (actual shutter
speed is 0.5H) to 1000H. The back plate control status can be read with RS-232C control and saved into
customer pages (page A is the power up default; whenever power is switched on, page A status is
loaded). This shutter control can be applied to both manual and async shutter modes. As shown in
Table1 (above), the shutter speeds are inversed in manual and async modes.
At async shutter, the internal VINIT is generated at the leading edge (negative going edge) of the
external trigger pulse. Internal timing, including the video sync, is reset. The shutter speed is the same
as in manual shutter mode. One frame of video output will start at the completion of the exposure time
(approx. 243
µ
sec.).
In Memory Output mode, the camera will output the same video from memory when VINIT is kept high
(5V) and update the image upon receiving the next trigger pulse. In Direct mode, with external pulse
input high, the video output is disabled as the camera keeps discharging the CCD image and provides
only black video. Therefore, if the direct digital output mode is chosen, the video output is only one
frame and then black video with sync.
3.1.1 (b) Internal Reset Mode
For Internal Reset Mode, set the 10-position dial switch from “1” to “9”. When this mode is selected,
the camera resets with internal VINIT timing, which is latched to Hd, and video output is also
synchronized with internal VINIT timing without further delay. The shutter speed is controlled by the
dial switch.
