DESCRIPTION

1

ICD

–

Test pin 1

A test pin. Set open or to L level in the normal mode.

2

EEST

ICU

–

Electronic exposure

control input 1

An input pin to control electronic exposure using EEUD

(pin 35) and EENR (pin 36).

L level

: Electronic exposure is stopped.

H level or open

: Electronic exposure is operated.

3

WIND

ON

N-ch

Open

Drain

Window pulse output

An output pin for window pulse.

WIND1 : When connected to EEST (pin 2), the

operation of electronic exposure can be

stopped at the upper side of monitor.

WIND2 : A pulse that picks out the center of CCD output.

At this time, set H level or open at EEST (pin 2).

As the output circuit of WIND is N-ch open

4

VRI

ICSU

–

Vertical reset input
