Image Acquisition Control
Basler scout light 63
Total Start Delay = 50.33 µs
Fig. 25: Exposure Start Controlled with an ExTrig Signal
You can calculate the frame readout time by using this formula:
Frame Readout Time = T
r
= ( AOI Height x C
1
) + C
2
Where the values for the constants C
1
and C
2
are from the table in Section 6.10 on page 65 for all
camera models except the slA750-60fm or from the table in Section 6.11 on page 70 for
slA750-60fm cameras.
For more information about the frame height, see Section 9.4 on page 111.
You can calculate the time to transmission end (T
e
) using these three steps:
1. Calculate the frame readout time (T
r
) using the formula above.
2. Calculate the base transmission time (T
b
) using these formulas:
(round the result up to the nearest integer)
T
b
= Packets per frame x 125 µs
