GETTING STARTED

USB DRIVER

Our CORE4 uses the Silicon Labs CP2102 USB-Serial chip for the PC connection.
Windows and other OS’s should automatically download and install the correct drivers for it.
But if you are having problems and not seeing a COM port in TunerStudio download and install the drivers manually from here: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
