Image Acquisition Control
100 Basler pilot
Note that, if the debouncer feature is used, the debouncer setting for the input line must be added
to the exposure start delays shown in Table 11 to determine the total start delay. For example,
assume that you are using an piA640-210 camera and that you have set the cameras for hardware
triggering. Also assume that you have selected input line 1 to accept the hardware trigger signal
and that you have set the Line Debouncer Time Abs parameter for input line 1 to 5 µs. In this case:
Total Start Delay = Start Delay from Table 11+ Debouncer Setting
Total Start Delay = 12.44 µs+ 5 µs
Total Start Delay = 17.44 µs

You can calculate the frame readout time by using this formula:
Frame Readout Time = ( AOI Height x C
1
µs ) + C
2
µs
Where the values for the constants C
1
and C
2
are from the table in Section 8.9 on page 102 and
AOI height is the height of the acquired frames as determined by the AOI settings.
For more information about the AOI height, see Section 11.6 on page 163.
For more information about the averaging feature, see Section 11.9 on page 173.
