External Trigger Shutter; To Set The External Trigger Shutter - Sony XC-ST51 Technical Manual

External Trigger Shutter

Inputting an external trigger pulse enables the camera
to capture fast-moving objects clearly with precise
timing.
Set DIP switches 6, 7, and 8 on the rear panel to Mode
1 or Mode 2.
When you set the trigger pulse width to 1/3 of a second
or more, the output signal changes to the normal
VIDEO signal.
There are two modes for the timing in which video
signals are obtained.
• Mode 1 (Non-reset mode)
In this mode, a video signal synchronized with a VD
signal is output after a trigger pulse is input.
– The video signal is synchronized with the external
VD signal when an external HD/VD signal is input.
– The video signal is synchronized with an internal
VD signal when no external HD/VD signal is input.
• Mode 2 (Reset mode)
In this mode, an internal VD is reset, then a video
signal is output a certain period of time after trigger
pulse input.
For details on the timing charts, see " Timing Chart" on
page 14 to 21.
