Card Control and Status

Card Status

The card indicates the status of the input signal with the four blue LEDs labled with the different supported formats (1080, 720, 625, 525), these LEDs correspond to AES Inputs 1-4. The four orange LEDs labeled User 1-4 correspond to AES Inputs 5-8 respectively. When the card has locked to an AES signal, a corresponding LED will be illuminated. When the card has not locked to an AES signal, the card will search for a signal and the lights will cycle rapidly.

Menu Navigation

The card can be configured from a menu system built in to the front card edge. This provides an intuitive and easy to use method for exploring and using the features of the card.

The menu is navigated by using the toggle switch and the two push buttons. The lower button is the “Enter” button to enter a submenu, and the upper button is the “Exit” button to exit a submenu. Moving the toggle switch up or down moves up or down in menu choices, and pressing the buttons moves in or out of sub menus.

The menu LEDs will illuminate from top to bottom to indicate increasing depth in the menu.

Output Source

Because the cards audio system functions like a router, each output can be sourced from any input channel. This parameter lets you choose from the many different sources. Here is an explanation of the different source names:

Source Name	Description
AnXX	Analog Audio channel X (1 through 8)
TgX	Test Generator channel X (1 through 4)

Output Gain

The gain of each output is adjustable from -40dB to +40dB in 0.1 dB steps. A setting of 400 is equivalent to +40dB.

Output Polarity

If set to “Norm” output polarity is the same as input polarity, if set to “Inv” the output polarity is inverted. This can be used to correct polarity errors in the input signals fed to the card.
