First of all you need to install GPS Generator and virtual null modem software (com0com).

By default 2 virtual COM ports will be installed. They will have CNCA0 and CNCB0 names. You can use default names (example for CNCA0 port name):

However, in order to use these virtual COM ports in other applications we suggest to rename them. It can be done in "Setup command prompt" or "Setup" utility (see "Programs / com0com" in Start menu).

If you prefere to use command prompt:

1. Launch the Setup Command Prompt shortcut.
2. Enter the change commands, for example:

command> change CNCA0 PortName=COM2
command> change CNCB0 PortName=COM3

If you use GUI "Setup" utility simply rename port names:

Please choose names for COM ports that are not currently used in your system.

After that 2 new COM ports will be available. Configure GPS Generator to write NMEA sentences to one of them (for example to COM2) and other application to read from another port (COM3). Launch the software and start Generator. If everything is done correctly client application will read NMEA sentences from COM3 port.
