2.3 Quick Start
After unpacking the DAC26EVM and verifying that the board is configured as
shown in Table 2−1, install the software.
Place the CD-ROM into the PC’s CD-ROM drive. Locate the Setup program
on the disk, and run it. The Setup program installs the DAC26EVM software
on the PC. Note that if the PC is running Windows

2000 or XP, administrator
privileges are required to install the software. Follow the instructions that the
installer provides.
When the installation is complete, connect a USB cable from the PC to the
DAC26EVM. A message may appear that a Human Interface /Audio Device
has been connected. Once this connection has been made, launch the
DAC26EVM software on the PC.
The software should automatically find the DAC26EVM. When the board is
found, the screen shown in Figure 2−1 appears.
