Using External Synchronization Signals
An external synchronization mode to synchronize to an external signal is provided on the
system. By using an external synchronization signal, recording can be conducted using
multiple cameras to synchronize the timing of the shots or to also synchronize the shots
with external measuring devices and lighting. The procedure and precautions for using the
external synchronization signal are explained below.
◼
Inputting an External Synchronization Signal
An external synchronization signal can be input with the system. See the chart below for
external synchronization input settings.
メニュー表示 内容
OFF Sets external synchronization off, operates independently.
ON CAM
The camera synchronizes with external signals below the currently set fps.
The fps set at the beginning is displayed on the display.
ON OTHER
The camera synchronizes with the signal input when changing the setting
to ON OTHER.
On the display, it becomes the fps at the time of setting change, and it
synchronizes with the signal below this frequency.
After synchronization setting, shutter speed and resolution can be
changed but fps can not be changed.
◼
Outputting an External Synchronization Signal
The system can externally output a synchronization signal. See the chart below for
external synchronization output settings.

•
When changing to the "ON OTHER" setting without inputting the synchronization signal,
the state will be "50Hz(E - Sync)".
After that, even if you input the synchronization signal, it will operate at 50 Hz so please
execute "ON OTHER" setting again after inputting the synchronization signal.
