Hi,
Vizard has a separate plugin for the Sensable Phantom. You can download example files for it here:

The plugin requires that you already have the OpenHaptics toolkit installed on your computer. The OpenHaptics toolkit is made by Sensable and probably came with your Phantom device. Once you have the toolkit installed the example files should work out of the box.
