7.6.2.6 Setting the State of User Settable Output Lines

As mentioned in the previous section, you can select "user output" as the signal source for an output

line. For an output line that has "user output" as the signal source, you can use camera parameters

to set the state of the line.

Setting the State of a Single User Output Line

To set the state of a single user output line:

 Use the User Output Selector to select the output line you want to set. For example, if you

have designated output line 2 as a user output, you would select output line 2.

 Set the value of the User Output Value parameter to true (high) or false (low). This will set the

state of the selected line.

You can set the Output Selector and the User Output Value parameter from within your application

software by using the pylon API. The following code snippet illustrates using the API to select "user

settable" as the source signal for output line 2 and how to set the state of the output line:

// Select "user output" as output line 2 signal source

Camera.LineSelector.SetValue( LineSelector_Out2 );

Camera.LineSource.SetValue( LineSource_UserOutput );

//Set the state of output line 2 and then read the state

Camera.UserOutputSelector.SetValue( UserOutputSelector_UserOutput2 );

Camera.UserOutputValue.SetValue( true );

bool currentUserOutput2State = Camera.UserOutputValue.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.

Setting the State of Multiple User Output Lines

If you have designated both of the cameras output lines as user outputs, you can use the User

Output Value All parameter to set the state of both outputs.

The User Output Value All parameter is a 32 bit value. As shown in Fig. 23, the lowest two bits of

the parameter value will set the state of the user outputs. If a bit is 0, it will set the state of the

associated output to low. If a bit is high, it will set the state of the associated port to high.
