the state of the associated line is currently low. If a bit is 1, it indicates that the state of the associated
line is currently high.

Checking the State of a Single Output Line
You can determine the current state of an individual output line. To check the state of a line:
Use the Line Selector parameter to select an output line.
Read the value of the Line Status parameter to determine the current state of the selected line.
A value of true means the line’s state is currently high and a value of false means the line’s
state is currently low.
You can set the Line Selector and read the Line Status 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 read the parameter value:
// Select output line 2 and read the state
Camera.LineSelector.SetValue( LineSelector_Out2 );
bool outputLine2State = Camera.LineStatus.GetValue( );
For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide
and API Reference.
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon Viewer, see Section 3.1 on page 23.
7.6.4 Checking the Line Logic
Checking the Line Logic Using Basler pylon
You can determine the type of line logic for each I/O line using Basler pylon:
Use the Line Selector parameter to select a line.
Read the value of the Line Logic parameter to determine the type of line logic used by the line.
The parameter will indicate whether the logic is positive or negative.
You can set the Line Selector and read the Line Logic parameter value from within your application
software by using the Basler pylon API. The following code snippet illustrates using the API to set
the selector and read the parameter value:
Indicates output line 1 state
Indicates output line 2 state
Indicates input line 1 state
Indicates input line 2 state
Indicates input line 3 state
