For use with the TLV320DAC32EVM, SW-2 positions 1 through 7 should be set to ON, while SW-2.8
should be set to OFF.
Ensure that the TLV320DAC32EVM is installed on the USB-MODEVM Interface board, aligning J1, J3, J4,
and J5 with the corresponding connectors on the USB-MODEVM.
Place the CD-ROM into your PC CD-ROM drive. Locate the Setup program on the disk, and run it. The
Setup program will install the TLV320DAC32 Evaluation software on the user's PC. The software for
NI-VISA Runtime will install automatically if it has not been previously installed. This software allows the
program to communicate with USB.
When the installation completes, click Finish on the TLV320DAC32EVM installer window. The user may
be prompted to restart the computer.
When installation is complete, attach a USB cable from the PC to the USB-MODEVM Interface board. As
configured at the factory, the board will be powered from the USB interface, so the power indicator LEDs
on the USB-MODEVM should light. At this time, the PC may go through an initialization of the drivers to
properly operate the USB-MODEVM interface board. Once this connection is established and any driver
configuration has completed, launch the TLV320DAC32EVM Evaluation software on the PC.
