Remark1 : T is the time required for reset. Time required for each model is as below.
Start reset from trailing edge of trigger terminal.
ARTCAM-130MI ---> 70msec approx.
ARTCAM-200MI ---> 100msec approx.
ARTCAM-300MI ---> 170msec approx.

Remark2 : The actual time for capturing is at least twice as long as the time
indicated in Remark1 (@ 8 bits).
T2 is the transfer time. IsCaptureFinish() is returned when T2 is completed.
Remark3 : Serial NO0963 has been altered to photo-isolation type as below.
The following is the internal equivalent circuit.
