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)
= 6 msec + 30.768 msec - 6 msec
= 30.768 msec
= 30768000 ticks
t
TransmissionDelay(Camera 3)
= 6 msec + 30.768 msec - 6 msec + 73.27 msec
= 104.038 msec
=
10403800 ticks
Notice
In Baumer GAPI the delay is specified 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
