Operation
This feature is especially important in capturing moving objects at the precise location of the field of view, such as belt conveyer, fast event observation and still picture capturing.
3.3.3 (b) Internal Fast Reset Mode
The video signal has no delay from the reset timing. Shutter speed range is 1/8,000 to 1/31,000 sec. Select a dial switch setting from “1” to “4.” When the fast reset 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.

3.3.3 (c) Internal Slow Reset Mode
The speed control ranges from 1/120 to 1/4,000 sec. With the internal slow reset mode selected, the camera operates the reset and shutter in the same way as the external pulse width control mode. When the external VINIT pulse is applied, internal VINIT is latched to HD and the second internal VINIT signal is delayed to set up the shutter speed period. The shutter speed is controlled by the dial switch from “5” to “8.” Video output timing starts right after the internal VINIT. For the timing of the delayed internal reset, LPULSE output of the
