In this case:
Total Start Delay = Start Delay from Table 9 + Debouncer Setting
Total Start Delay = 17.62 µs+ 5 µs
Total Start Delay = 22.62 µs
You can determine the readout time by reading the value of the Readout Time Abs parameter. The
parameter indicates what the readout time will be in microseconds given the camera’s current
settings. You can read the Readout Time Abs parameter value from within your application software
by using the Basler pylon API. The following code snippet illustrates using the API to get the
parameter value:
double ReadoutTime = Camera.ReadoutTimeAbs.GetValue( );
You can also use the Basler pylon Viewer application to easily get the parameter value.
For more information about the pylon API and the pylon Viewer, see Section 3 on page 27.
You can calculate an approximate frame transmission time by using this formula:
Note that this is an approximate frame transmission time. Due to the nature of the Ethernet network,
the transmission time could vary. Also note that the frame transmission cannot be less than the
