Summit Semiconductor Confidential 1 Introduction The LG Innotek USB Tx implements a complete Summit Wireless audio network transmitter in a small, inexpensive form factor. This guide discusses the required equipment, software and application specific configurations to operate the USB Tx using: Windows OS, Mac OSX, iOS and Android devices.
Summit Semiconductor Confidential 3.1 Installing TUSB Windows Driver It is recommended that you install the device driver prior to plugging in the USB Tx. If you plug in the USB Tx prior to installing the device driver, you will see the following if you open up your computers Device Manager. The LG Innotek USB Tx requires a device driver to operate under Windows OS. As part of the release package for the USB Tx, Summit includes a demonstration USB driver created by Thesycon.
Summit Semiconductor Confidential In this directory, you will find an executable for installing the device driver. As shown below, double click on the following file: Summit_eval_DriverSetup_v2.29.0.exe. This will launch the device driver installer. The following pictures show the various screens as you progress through the installation. LG Innotek USB Transmitter Startup & Demo Guide v1.
Summit Semiconductor Confidential The installation tool provides the ability to set the install location of the driver. We strongly recommend that you install the device driver in the default location as shown below. LG Innotek USB Transmitter Startup & Demo Guide v1.
Summit Semiconductor Confidential The program will install a number of files, and when this is complete, you will see the screen show the installation was successful. Once the installation is complete, you can then plug the module into the system. 3.2 Windows Setting for the LG Innotek USB Tx The Windows operating system provides several different controls for setting the behavior of the USB Tx.
