3 User Interface
3.1 Control options
The AMX-3981 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
parameter values (see section 4).
• Miranda’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).
• Miranda’s RCP-200 panel (check for availability).
3.2 Card-Edge Status LED
The status monitor LED is located on the front card-edge of the AMX-3981, and is visible through the front access
door of the DENSITÉ frame. This multi-color LED indicates the status of the AMX-3981 by color, and by
flashing/steady illumination.
The chart shows how the various error conditions that can be flagged on the AMX-3981 affect the LED status.
• If a cell is gray, the error condition cannot cause the LED to assume that status
• If more than one LED status is possible for a particular error condition, the status is configurable.
See Section 5.16 for details.
• The factory default status is shown by a 
The LED will always show the most
severe detected error status that it is
configured to display, and in the chart
error severity increases from left to
right, with green representing no
error/disabled, and flashing red the
most severe error.
If the LED is Flashing Yellow, it
means that the card is selected for
local control using the Densité frame’s
control panel. See Section 4 for
details.
