In general, the transmission delay is calculated as:

Therewith for the example, the transmission delays of camera 2 and 3 are calculated as
follows:
t
TransmissionDelay(Camera 2)
= t
exposure(Camera 1)
+ t
readout(Camera 1)
- t
exposure(Camera 2)
t
TransmissionDelay(Camera 3)
= t
exposure(Camera 1)
+ t
readout(Camera 1)
- t
exposure(Camera 3)
+ t
transferGige(Camera 2)
Solving this equations leads to:
t
TransmissionDelay(Camera 2)
= 20 msec + 35.3 msec - 20 msec
= 35.3 msec
= 35300000 ticks
t
TransmissionDelay(Camera 3)
= 20 msec + 35.3 msec - 20 msec + 10.48 msec
= 45.78 msec
= 45780000 ticks
Notice
In Baumer GAPI the delay is specied in ticks. How do convert microseconds into ticks?
1 tick = 1 ns
1 msec = 1000000 ns
1 tick = 0,000001 msec
ticks= t
TransmissionDelay
[msec] / 0.000001 = t
