External Trigger Shutter - Sony XC-HR90 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 1/4 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
– The video signal is synchronized with an internal VD signal when no external HD
External or internal synchronization is selected automatically depending on the presence or absence of external

HD 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.
