5.11.3 Input Line Inverter

You can set input line Line 1 and GPIO lines Line 3 and Line 4, if configured for input, to invert or
not to invert the incoming electrical signal. Therefore, the inverter setting is one of the factors
defining whether a given electrical signal level will be considered to correspond to a "high" or "low"
logical line status.
If you enable or disable the inverter one frame acquisition will automatically occur.
To set the invert function for an input line:
1. Use the Line Selector to select, for example, Line 1.
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:
// Select the input line
camera.LineSelector.SetValue(LineSelector_Line1);
// Enable the line inverter on the selected line
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
