Trigger Signal Input
Trigger signals can be input via pins 2, 3, and 4 of the DC power supply input connector, or by software command.
Switchover of the trigger signal can be changed using TriggerSource. For details, see “Trigger Control” (page 17).
Trigger signal polarity
Positive polarity refers to a trigger signal activated by a Low to High rising edge, or High-level interval. Negative
polarity refers to a trigger signal activated by a High to Low falling edge, or Low-level interval. The default value of the
camera is negative polarity.
DC power supply input connector specifications
Notes
• When inputting a trigger signal to the camera using the DC-700/700CE, use 5 V DC or lower as the logical high level.
• Make sure to supply power to the unit and confirm that the unit is operating before inputting a trigger signal. If you
input a trigger signal to the unit without the power supplied, this may cause a malfunction of the camera.
