When PurePath Console is launched, it queries the user on how many devices are connected to an AC-MB, as shown in Figure 21. In this dialog window, after selecting two PCM6xx0 devices and clicking on next, the main window shown in Figure 22 launches.
Figure 21. PurePath Console Input Number of Devices Dialog 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 22. Clicking on device icon A programs the lower number I2C address, B programs the next I2C address, and so forth.
Figure 22. PurePath Console Main Window The Audio Serial Bus tab assigns each channel of a device to a slot. In Figure 23, the device A input channels 1-4 are assigned to slots 0-3, respectively. In Figure 24, 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.
