1.  Once your USB Driver has been installed, you will need to confirm which COM Port your PC 

has assigned to it in order to properly configure any software that will be utilizing the GPS data 
being received.

6.  Once you have identified the COM port number, any software that you utilize must be 

configured to read GPS data from this COM port. 

We strongly suggest that you first test your USB GPS with the included GPS Info utility program to 
confirm that the GPS receiver if functioning properly on your PC and that you have successfully 
configured the right COM Port setting.  Once this has been done, close the GPS Info program and 
start your application for COM port configuration. 

NOTE: By default, your PC will not allow you to run multiple applications from a single COM port.  It 
is important that you close any previously opened GPS application before switching to another 
GPS application as the GPS receiver and data will not be found by the new program.   

There are special utilities available to split data into multiple COM ports for use by more than one 
application simultaneously.  (see:
