Hi Ben,
SmartConversion is a "tie-line" management system that uses external converters and some inputs pair with outputs to manage the conversion needs in the background.
There is no actual conversion hardware in the switcher. So if you don't have any converters setup under smart conversion then they won't be available for you to use. If all your trying to do is convert a single Aux then you would be best to just attach the converter to that output and then onward to the device your making the conversion for.
