6. External Triggered Shutter
Inputting a trigger from an external device will enable capturing of high-speed moving objects at a correct position.
Set DIP switches 6, 7, and 8 on the rear panel to those specified for mode 1 or 2. (See the figures on the following pages.)
When the trigger pulse width is set to 1/3 s or more, the output is switched to a normal video signal.
There are two modes for the timing of obtaining videos
• Mode 1 (non-reset mode)
A video synchronous with the VD signal is output after a trigger input in this mode.
- When an external VD/HD signal is input: The video synchronizes the external VD signal.*
- When an external VD/HD signal is not input: The video synchronizes the internal VD signal.
• Mode 2 (reset mode)
In this mode, the internal VD signal is reset, and the video is output after a certain period of time has elapsed since a
trigger pulse is input.
● For individual timing charts, see pages 19 to 26.
The shutter speed can be specified by either setting the DIP switches or specifying trigger pulse widths.
● For how to specify trigger pulse widths, see page 13.
