3. COM PORT VERIFICATION (Windows)
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.
2.Your USB GPS MUST be plugged into your USB port at this time.
3.Using Window’s Control Panel, select System > Hardware > Device Manager
4.Then look under the heading of: PORTS (Com & LPT)
5.There should be a listing for: Prolific
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 MiniCDU utility program to confirm that the GPS receiver is functioning properly on your PC and that you have successfully configured the right COM Port setting. Once this has been done, close the MiniCDU 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: http://franson.com/gpsgate/
