The ADX-1901 can be controlled in three different ways:
• The local control panel and its push-buttons can be used to move through a menu of parameters and to adjust

• Grass Valley’s iControl system can be used to access the card’s operating parameters from a remote computer,
using a convenient graphical user interface (GUI) (see section 5 ).

3.2 Card-Edge Status LED
The status monitor LED is located on the front card-edge of the ADX-1901, and is visible through the front access door

means that the card is selected for
local control using the Densité frame’s
