TM-6710/6710CL High-Speed Progressive Scanning CCD Camera

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 H

D

, and video output is also synchronized with internal

VINIT timing without further delay. The shutter speed is controlled by the dial switch.

Internal Fast Reset Mode

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 H

D

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 51-pin connector can be used.
