Hi Mr SSL,
As you are using TestStand 3.0.
Make sure your output string from virtual keyboard VI is connected to the VI's connector pane.
When you specify your module in your teststand step you will see the output of your VI made available to allow you to specify a TestStand property. If you have placed this VI in the PreUUT sequence, then set the output string to pass the value to Locals.SerialNumber.
I have attached an example.
