3.1.2.1 Basic Setup Before Evaluation

Follow these steps to set up the DEM-PCM2912A EVM for use with a Macintosh computer.

  1. Connect the USB connector of the DEM-PCM2912A EVM to an available USB connector (or hub) port on the lab computer. The DEM-PCM2912A EVM can be connected directly to the PC without an additional USB cable.
    After the EVM is connected to the PC, the standard Mac OS driver installs automatically to the computer system. A custom driver for the DEM-PCM2912A is unnecessary.
  2. Open the System Environment Settings from the Start menu. Open the Sound options from the System Environment settings.
  3. Select the Input tab and confirm the USB audio codec appearance as the default recording device, as shown in Figure 4-7.
