You can also use the Basler pylon Viewer application to easily set the parameters.

For more information about the pylon API and the pylon Viewer, see Section 3.1 on 

page 37

.

For more information about changing the selection of a camera output signal as the source signal 
for an output line, see Section 5.12.1 on 

page 69

.

For more information about the electrical characteristics of output line Line 2, see Section 5.8.1 on 

page 52

, and of GPIO Line 3 and Line 4, set for output, see Section 5.9.3.1 on 

page 57

Flash Window Signal

Cameras with a rolling shutter imaging sensor (acA1920-25, acA2500-14, acA3800-14, 
acA4600-10 models) can provide a flash window output signal to aid you in the use of flash lighting. 
The flash window signal will go high when the flash window for each image acquisition opens and 
will go low when the flash window closes. Figure 62 illustrates the flash window signal on a camera 
with the shutter operating in the electronic rolling shutter mode.    

For more information about the rolling shutter and the flash window, see Section 6.6.2 on 

page 114

.

The flash window signal is also available on cameras with a global shutter imaging 
sensor. On global shutter cameras, the flash window signal is simply the 
equivalent of the exposure active signal.
