3.1 Control options
The IRD-3811 can be controlled in two 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 3.3).
•
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 3.4)
3.2 Card-Edge Status LED
The status monitor LED is located on the front card-edge of the IRD-3811, and is visible through the front access door
of the DENSITÉ frame. The chart shows how the various error conditions that can be flagged on the IRD-3811 affect
the LED status.
