CODEC Motherboard Manual Version 1.3 Page 11 of 66 April 12, 2016CODEC Motherboard5.1.2 Power Up IndicatorThe middle status indicator is the Power Up Indicator. This will be Green after the software haspowered up all elements on the motherboard necessary to interoperate with the daughter card. Ifthe indicator is white, then the motherboard and communications between the motherboard anddaughter card have not been set up, and no interaction with the daughter card is possible.5.1.3 Busy IndicatorThe status indicator on the right-hand side indicates when the GUI Application is making changesto the motherboard and/or the daughter card. This will be Green when all changes are completedand the hardware is configured for operation. This indicator will be white when the GUIApplication is busy making changes to the motherboard and/or the daughter card.5.2 Introduction to Main Menu BarThe Main Menu Bar is included on the Demo Panel, the start-up screen, and all other views. Thisenables direct and quick access to some features common to all devices. Many of these featuresare for more experienced users, and this section can be studied as needed at a future time.5.2.1 DeviceThe Device menu allows changing the selected daughter card device without restarting theapplication. This can be useful if the wrong device was accidentally selected, or it can be used toswitch daughter cards without restarting or powering down the hardware. However it is preferredto power-down the hardware and restart the application to change daughter cards This moreconservative procedure will insure the greatest reliability for both the hardware and software.5.2.2 ModeThe Mode selection is normally automatic and the user should NOT change this. This menu itemenables changing the hardware control bus protocol between the motherboard and the audiodevice being tested.The Mode feature is included for instances when the motherboard or daughter card hardware hasbeen custom modified to be hard-wired into a particular control bus configuration. Then, it isimportant to have a top-level menu control to change this selection. The control bus modes areexplained in more detail in the section describing the Device Control menu tab functionality.5.2.3 ConfigThe Config menu enables Exporting or Importing settings from a standard file stored on the PCsystem. This feature saves only the settings for the audio device being tested, and not theconfiguration of the motherboard itself. So, the motherboard must already be initialized and setup in the desired mode before executing the Import function.Export/Import is useful for saving configurations for future use, or for sharing configurations withother users. It is also a convenient way to copy/paste a set of desired register settings from theEVB environment directly into software used to control the device in the actual end product.
