Basler scout light GigE 137
Fig. 43: 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.
The trigger ready signal can be assigned to physical output line 1 on the camera.
Selecting the Trigger Ready Signal as the Source Signal for the Output Line
The trigger ready signal can be selected to act as the source signal for output line 1. Selecting a
source signal for the output line is a two step process:
 Use the Line Selector to select output line 1.
 Set the value of the Line Source Parameter to the trigger ready output signal.
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.
