Figure 12. Initiating Connect from the Target Menu
After the Target-Connect operation, the GUI window background changes from white (with grid) to a solid
light-green. All the blocks seen in the GUI window are now active and any updates made on these blocks
updates the corresponding register space. Also, note that the configuration menu options on the right-
hand side (highlighted with blue-box in fig-13 below) are now grayed out and can’t be updated. The
Target-Connect operation automatically updates the trim register (0x1B) to factory-trim mode, now the
device can be set to stream audio output with only two additional operations: exit-shutdown and un-mute
The device shut-down mode can be toggled through the Shutdown-Checkbox (highlighted with a red-box
in
Figure 13 ). Uncheck this box to bring the device out of shut-down. Similarly, the mute state of master-
volume can be toggled using the Mute-Checkbox (highlighted with a red-box in Figure 13 ). After un-muting
the master-volume, the volume slider should be used to set the volume to the desired level. The current
volume level will be displayed in the menu-area on the right-hand side of the GUI window. After
completing these basic operations, the device should now be streaming audio.
