10.13 User Defined Values
The camera can store five "user defined values". These five values are 32 bit signed integer values
that you can set and read as desired. They simply serve as convenient storage locations for the
camera user and have no impact on the operation of the camera.
The five values are designated as Value 1, Value 2, Value 3, Value 4, and Value 5.
Setting User Defined Values Using Basler Pylon
Setting a user defined value using Basler pylon is a two step process:
 Set the User Defined Value Selector to Value 1, Value 2, Value 3, Value 4, or Value 5.
 Set the User Defined Value parameter to the desired value for the selected value.
You can use the pylon API to set the User Defined Value Selector and the User Defined Value
parameter value from within your application software. The following code snippet illustrates using
the API to set the selector and the parameter value:
// Set user defined value 1
Camera.UserDefinedValueSelector.SetValue( UserDefinedValueSelector_Value1 );
Camera.UserDefinedValue.SetValue( 1000 );
// Set user defined value 2
Camera.UserDefinedValueSelector.SetValue( UserDefinedValueSelector_Value2 );
Camera.UserDefinedValue.SetValue( 2000 );
// Get the value of user defined value 1
Camera.UserDefinedValueSelector.SetValue( UserDefinedValueSelector_Value1 );
int64_t UserValue1 = Camera.UserDefinedValue.GetValue();
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 19.
Setting User Defined Values Using Direct Register Access
To set the user defined values via direct register access:
 Set the value of the User Defined Value 1 register, the User Defined Value 2 register, the User
Defined Value 3 register, the User Defined Value 4 register or the User Defined Value 5 register
as desired.
For more information about direct register access, see Section 3.2 on page 21.
