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.
4.3.1. Inputting External Synchronization Signal
An external synchronization signal can be input with the system. See the chart below for external
synchronization input settings.

Contents
Signal (Input Signal Conditions)
OFF
Sets external synchronization off, operates
independently.
(none)
ON CAM POS
Synchronizes to a positive polarity signal from
Photron products.
FET Input 0V - +12V (H level
+2.5V to +12V), Positive Polarity
ON CAM NEG
Synchronizes to a negative polarity signal from
Photron products.
FET Input 0V - +12V (H level
+2.5V to +12V), Negative
Polarity
ON OTHERS
POS
Synchronizes to a positive polarity signal from
an external device
(including other Photron products).
FET Input 0V - +12V (H level
+2.5V to +12V), Positive Polarity
ON OTHERS
NEG
Synchronizes to a negative polarity signal from
an external device (including other Photron
products).
FET Input 0V - +12V (H level
+2.5V to +12V), Negative
Polarity
4.3.2. Outputting External Synchronization Signal
The system can externally output a synchronization signal. Output of the external synchronization
signal is performed from the GENERAL OUT connector explained in section “2.3.6. I/O PORT
”. See the chart below for external synchronization output settings.

SYNC POS
Outputs a positive polarity
vertical synchronization signal.
CMOS (74ACT541 buffer)
output, positive polarity
Approx. 140nsec
SYNC NEG
Outputs a negative polarity
vertical synchronization signal.
CMOS (74ACT541 buffer)
output, negative polarity
Approx. 145nsec
Signal cable condition: 50cm
4.3.3. Synchronization with a variable frequency
When synchronizing with a varying input frequency signal, the frame rate and resolution specified
before recording will be kept as a maximum value, and the camera frequency can alternate to a
minimum of about 60Hz (50Hz) following to the input signal, even under the recording mode.
