Figure 1. Windows 10 with a connected Device
You will see one or more USB serial devices. You can eject the USB cable to detect which one
is NMEA 2000 USB Gateway.
Please remember the port number which was assigned automatically to the Device. If the port number
is above COM9, you must change the port number to COM1 — COM9. Open the device’s properties, switch
to the “Port Settings” tab, and click the “Advanced…” button. Select another port number in the bottom left
corner (see Figure 2). Usually you can ignore the “in use” mark near the port number, it means that this port
was assigned to some other device previously; some computers have dozens of ports “in use” when actually
there are no devices connected.
