6.2Installation

Ensure that the TLV320AIC12KEVMB/14KEVMB 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 Found New Hardware Wizard will show up on the screen. Select the 'No, not this time' radio button and click 'Next >'. Select 'Install the software automatically (Recommended)' and click 'Next >'. If the driver installs correctly the message: 'The wizard has finished installing the software for: AIC12K/14K EVM' should appear. Click 'Finish'. The AIC12K/14K EVM driver should now be installed. The device 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 Figure 2 should appear.
