3.19.5. Synchronizing the System with Other External Devices
(Frame Rate Synchronized Recording)
With the system, in addition to the frame rate preset in the system, a function has been provided
where you can receive a synchronization signal externally, set the frame rate with that frequency,
and record.
In this way, for example, the system can be synchronized with a dynamic body that spins at 1,350
revolutions a second to conduct high-speed recording at 1,350 fps. This can open up broad
applications that were unavailable until now.

Conceptual Diagram of External Synchronized Recording
This function using an external synchronization signal to synchronize the camera to the desired
frame rate is explained here.
When conducting frame rate synchronization recording with the system, the input signal must meet
the following conditions.
■ FET Input 0V - +12V (H level +2.5V to +12V), positive polarity or negative polarity
■type 2100K : 60Hz
(50Hz for PAL) to 2,100,000Hz
■type 480K : 60Hz
(50Hz for PAL) to 480,000Hz
■type 200K : 60Hz
