When PurePath Console is launched, it queries the user on how many devices are connected to an AC-MB, as shown in Figure 4-3. In this dialog window, after selecting two TLV320ADC5140 devices and clicking on Next, the main window shown in Figure 4-4 launches.

PurePath Console configures only one device at a time. The devices are labeled by a device icon with a letter at the top of the screen, as shown in Figure 4-4. Clicking on device icon A programs the lower number I²C address, B programs the next I²C address, and so forth.

The Audio Serial Bus tab assigns each channel of a device to a slot. In Figure 4-5, the device A input channels 1-4 are assigned to slots 0-3, respectively. In Figure 4-6, the device B input channels 1-4 are assigned to slots 4-7. Note that the previous slots in the TDM bus are not shown, but an ellipsis at the beginning of the audio interface signal line plot in BCLK, FSYNC, and SDOUT signifies that other slots precede these slots.
