5.12.5 Output Line Inverter
You can set output line Line 2 and GPIO lines Line 3 and Line 4 if configured for output, to invert or
not to invert the electrical output signal.
1. Use the Line Selector to select, for example, Line 2.
2. Set the value of the Line Inverter parameter to true to enable inversion on the selected line or
to false to disable inversion.
You can set the Line Selector and the Line Inverter parameter value from within your application
software by using the pylon API. The following code snippet illustrates using the API to set the
selector and the parameter value:
// Enable the line inverter on output line Line 2
camera.LineSelector.SetValue(LineSelector_Line2);
camera.LineInverter.SetValue(true);
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 37.
5.12.6 Working With the Timer Output Signal
As mentioned in Section 5.12.1 on page 69, the source signal for an output line can be set to
Timer 1 Active . The camera has one timer designated as Timer 1. When you set the source signal
for the output line to Timer 1 Active, Timer 1 will be used to supply the signal to the output line.
Timer 1 operates as follows:
A trigger source event occurs that starts the timer.
A delay period begins to expire.
When the delay expires, the timer signal goes high and a duration period begins to expire.
When the duration period expires, the timer signal goes low.
