For use with the TLV320AIC12KEVM/14KEVM, SW-2 positions 1, 3, 4, 5 and 6 should be set to ON, while
SW-2 positions 2, 7 and 8 should be set to OFF.
Ensure that the TLV320AIC12KEVM/14KEVM is installed on the USB-MODEVM Interface board, aligning
J1, J2, J3, J4, 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 start it. The
Setup program will install the TLV320AIC12K/14K Evaluation Tool software on your PC.
The NI-VISA Runtime installer is embedded to the TLV320AIC12K/14K Evaluation Tool installer. This
software allows the program to communicate with the USB-MODEVM.
When the installation completes, click
Finish
on the TLV320AIC12K/14K Evaluation Tool installer window.
You may be prompted to restart your computer.
When installation is complete, attach a USB cable from your 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
and the 'USB ACTIVE' LED on the USB-MODEVM should light.
The

and click '

should now appear on the Device Manager as '
NI-VISA USB Devices>AIC12K/14K EVM
' and as '
Sound,
video and game controllers>USB Audio Device
'.
Once the device drivers are installed launch the TLV320AIC12K/14K Evaluation Tool software on your
PC, located on the computer's desktop or in 'Start>Programs>Texas Instruments'.
The software should automatically find the TLV320AIC12K/14K, and a screen similar to the one in
should appear.
