signal based on the current exposure time parameter setting, the current size of the area of interest,
and the time it will take to readout the captured pixel values from the sensor.
The trigger ready signal is especially useful if you want to run the camera at the maximum
acquisition frame capture rate for the current conditions. If you monitor the trigger ready signal and
you begin acquisition of each new image immediately after the signal goes high, you will be sure
that the camera is operating at the maximum acquisition frame rate for the current conditions.
Fig. 65: Trigger Ready Signal
You should be aware that if the Acquisition Frame Rate Abs parameter is enabled, the operation of
the trigger ready signal will be influenced by the value of the parameter:

If the value of the parameter is greater than zero but less than the maximum allowed, the
trigger ready will go high at the rate specified by the parameter value. For example, if the
parameter is set to 10, the trigger ready signal will go high 10 times per second.

If the value of the parameter is greater than the maximum allowed acquisition frame rate with
the current camera settings, the trigger ready signal will work as described above and will go
high at a point that represents the maximum acquisition frame rate allowed.
By default, the trigger ready signal is assigned to physical output line 2 on the camera. However,
the assignment of the trigger signal to a physical output line can be changed.
For more information about changing the assignment of camera output signals to physical output
lines, see Section 8.2.1 on
page 93 .
For more information about the electrical characteristics of the camera’s output lines, see
Section 7.7.2 on
page 87 .
If you attempt to start an image acquisition when the trigger ready signal is low,
the camera will simply ignore the attempt.
The trigger ready signal will only be available when hardware triggering is
enabled.
