Download the GS-911 downloader, from the Downloads page. This is a Windows PC based application that ONLY runs on a Windows PC.
Once downloaded, run the GS-911 downloader. The downloader will instruct you when to connect your GS-911 interface to the PC, after which it will connect to the server to determine which versions are available for download. A browser window will be opened and list the GS-911 interface details and appropriate download links.
If your GS-911 interface has not yet been registered – typical for a new interface – the server will initiate the registration page as a first step, prior to listing your downloadable links.
From the browser window that the GS-911 downloader opened, download and install any of the PC versions available to you.
Once installed, run the GS-911 Application, by default the Setup window will open, or you can find it under Tools in the menu bar. Make sure you have USB selected and then click Test interface. This will test the interface, and report the serial number, firmware version, battery voltage of the motorcycle (if connected to a motorcycle) etc. A firmware update may be required.
Congratulations! Your GS-911 interface is now ready to use.
