Software Installation
2.1 Graphical User Interface (GUI)
To use the ADC128S102EVM, install the ADC12xS10x software:
1. If the ADC128S102EVM came from an FAE, the software GUI is in a .zip file. Otherwise, click
http://www.ti.com/product/adc128s102, scroll down to the Software section, and download the latest
evaluation software.
2. Unzip the downloaded file into a known directory, and run the setup.exe file located in [Unzip
location]\ADC12xS10x\EVM_GUI\ADC12xS10x_Installer_v11.zip\ADC12xS10x_Installer
\Installer\Volume. Follow the pop-screen instructions by clicking the Next button to install the software.
