3 Operation
105
The digital output is set to "High" regardless of the exposure.
Constant low
The digital output is set to "Low" regardless of the exposure.
Flash high active
The digital output is set to "High" during the exposure.
Flash low active
The digital output is set to "Low" during the exposure.
Global exposure window
The values for flash delay and duration are calculated to trigger the flash when all sensor rows are exposed
simultaneously for sensors with rolling shutters. If you are using the "Global start" function, the flash delay has to
be set to 0 (see also Shutter methods ).
Flash delay
Sets the delay for the digital output. After an exposure has started, activating the digital output is delayed by the
time set in flash delay.
Duration (0 = Auto)
Sets the switching time of the digital output. The digital output is activated for the time set in "Duration". The
value 0 means that the signal is active over the entire exposure time (default).
Requirement in freerun mode: The "Global exposure window" must be enabled.
Pulse-width modulation (only DC320x Cameras)
The pulse-width modulation (PWM) can be controlled by two parameters (frequency and duty cycle) and can be set
on the flash output and the additional GPIOs respectively (see also is_IO() ).
Frequency (in Hz)
Frequency of the pulse-width modulation (PWM)
Duty cycle (in %)
Duty cycle of the pulse-width modulation (PWM width)
GPIO
The GPIOs (General Purpose I/O) of the DCx Cameras can be used as inputs or outputs. See the Model
comparison list for the camera models which support GPIO.
Status
Polls the signal level applied to the GPIO.
Input
Sets the GPIO as trigger input.
Output low
Sets the GPIO as output. The output signal is statically set to "low".
Output high
Sets the GPIO as output. The output signal is statically set to "high".
Flash
Sets the GPIO as flash output. The settings you made in the "Flash output" box are used.
Note
Detailed information on wiring the DCxCamera inputs and outputs is provided in the "Electrical Specifications"
section of the Specifications chapter.
