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.
3.16.1. Inputting an External Synchronization Signal
When INPUT 1 or 2 is set to SYNC POS/NEG, an external synchronization signal can be input with
the system. See the chart below for external synchronization input settings.

Signal (Input Signal Conditions)
OFF
Sets external synchronization off, operates
independently.
(none)
ON CAM POS
Synchronizes to a positive polarity signal
from the system.
FET Input 0V - +12V (H level
+2.5V to +12V), Positive
Polarity
ON CAM NEG
Synchronizes to a negative polarity signal
from the system.
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
3.16.2. Outputting an External Synchronization Signal
The system can externally output a synchronization signal.

SYNC POS
Outputs a positive polarity
vertical synchronization signal.
CMOS (74LVC2T45 buffer)
output, positive polarity
Approx. 168nsec
SYNC NEG
Outputs a negative polarity
vertical synchronization signal.
CMOS (74LVC2T45 buffer)
output, negative polarity
Approx. 168nsec
3.16.3. 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.
