port on your PC.
·Check to make sure the COM port is not configured for another application. Personal Digital Assistant (PDA) soft-
ware or other device applications may be occupying the port at start up. You may
have to exit the occupying software to release the COM port for the Link software.
·Make sure the Link serial cable is securely connected to both the COM port on your PC and the PowerTap comput-
er. Notice that the PowerTap computer should be awake (LCD segments
illuminated) before you attach the PowerTap computer to the Link serial cable. Notice that the screen goes blank
