You can add a VISA resource name control to the front panel of a PDA or Touch Panel VI, but the control is not visible when you run the application on a PDA or Touch Panel target.
To enter the resource name in a PDA or Touch Panel application, you can use a string control instead of the VISA resource name control. Use the VISA Find Resource function to return a list of available resources to the string control.
To display the value of the VISA resource name control in a PDA or Touch Panel application, wire a string indicator to the VISA resource name control.
