3.6.4 Internal Shutter Speed with Slow Mode (TM-1020-15 Only)

FIGURE 13.

Internal Shutter Speed with Slow Mode (TM-1020-15 Only)

The speed control ranges from 1/120 to 1/950 sec. The video signal starts with internal VINIT. Select a
dial switch setting from “1” to “4.” 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.
