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.
