Take a look at the information in this
ART SmartTrack post and try a simple Vizard script to test the connection:
Code:
import viz
viz.go()
# VRPN Tracker connection (to ART Dtrack)
vrpn = viz.add('vrpn7.dle')
headTracker = vrpn.addTracker('DTrack@localhost') #Default sensor is 0
flystickTracker = vrpn.addTracker('DTrack@localhost',1) #Try index 1 or 2 here
flystickButtons = vrpn.addButton('DTrack@localhost') #Flystick buttons
flystickJoystick = vrpn.addAnalog('DTrack@localhost') #Flystick analog thumb joystick
