GUIDE TO INSTALLATION AND OPERATION
FRS-1801 | 7
3 Operation
3.1 Control options
The FRS-1801 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 FRS-1801, and is visible through the front
access door of the DENSITÉ frame. This multi-color LED indicates the status of the FRS-1801 by color, and
by flashing/steady illumination.
The chart shows how the various error conditions that can be flagged on the FRS-1801 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 3.4.16 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.
