The TAS5622-TAS5624DDVEVM is controlled by the Input-USB Board 3 with the TAS5538 GUI. The
TAS5538 GUI provides control of all registers in TAS5538. Download the current version of the GUI zip
file "TAS5538_xxxx.zip" from the TAS5622DDVEVM folder or the TAS5624DDVEVM folder on
http://www.ti.com to a convenient location on the host PC. Create a new folder at a convenient location
and extract the files from the zip file to the new folder. Be sure to check the box labeled “Use folder
names” during extraction. Then connect the USB cable between the host PC and jack USB-IN on the
Input-USB Board 3. Then turn on the 12V power supply and the PVDD power supply in that order.
Start the GUI by opening "TAS55XX_GUI.exe" in the new folder. Startup will take a few seconds and the
following window will open.
