2.1 Unpacking

Make sure the following items have been shipped with your ADC-1722. If any of the following items are
missing, contact your distributor or Miranda Technologies Inc.

• ADC-1722 Dual analog audio to AES converter

• ADC-1722-DRP-75 or ADC-1722-DRP-110 Dual Rear Panel, or ADC-1722-SRP-75 or ADC-1722-SRP-110

Single Rear Panel (see figure)

2.2 Installation in the Densité frame

The ADC-1722 and its associated rear connector panel must be mounted in a DENSITÉ frame. It is not
necessary to switch off the frame’s power when installing or removing the panel. See the DENSITÉ Frame
manual for detailed instructions for installing cards and their ass oc iate d rear pan el s.

When a double–width rear panel is used, the module must be installed in the right-most of the two slots
associated with the rear panel in order to mate with the rear-panel connectors. If it is placed in the wrong slot,
the front panel LED will flash red. Move the card to other slot for correct operation. No damage will result to
the card should this occur.

If a card is placed in the wrong slot, its front panel LED will flash red. Move the card to other slot for correct
operation. No damage will result to the card should this occur.

Attention:

For cards with an Assy# 0696-1200-2xx only – if a reference card is installed in the DENSITÉ frame, e.g. a
REF-1701 in slot #20 or a REF-1801 in slot #10, you have to set the JP1 jumper accordingly. Please refer to
the silkscreen on the card for the jumper position. This selection is automatic with an Assy# starting at 0696­1200-400.

3 Operation

3.1 Control options

The ADC-1722 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
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 ADC-1722, and is visible through the front
access door of the DENSITÉ frame. This multi-color LED indicates the status of the ADC-1722 by color, and
by flashing/steady illumination.

The chart shows how the various error conditions that can be flagged on the ADC-1722 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 3.4.5 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.

3.3 Local control using the Densité frame control panel

3.3.1 Overview

Push the SELECT button on the ADC-1722 card edge
to assign the local control panel to operate the ADC-

1722. Use the control panel buttons to navigate through

the menu, as described below.
All of the cards installed in a Densité frame are

connected to the frame’s controller card, which handles
all interaction between the cards and the outside wor ld .
There are no operating controls located on the cards
themselves. The controller supports remote operation
via its Ethernet ports, and local operation using its
integrated control panel.

The local control panel is fastened to the front of the
CPU-ETH2 controller card, and when installed can
be accessed by opening the front door of the frame
The panel consists of a display unit capable of
displaying two lines of text, each 16 characters in
length, and five pushbuttons .

The panel is assigned to operate any card in the
frame by pushing the SELECT button on the front
edge of that card.

• Pushing the CONTROLLER button on the
control panel selects the Controller card
itself.

• The STATUS LED on the selected card flashes yellow.

The local control panel displays a menu that can be navigated using the four pushbuttons located beneath
the display. The functionality of the pushbuttons is as follows:

[+] [–] Used for menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button

once enables modification of the value using the [+] and [–] buttons; a second push confirms the
new value

[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC]

causes the parameter to revert to its former value.

Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC]

does not exit the menu system. To exit, re-push the [SELECT] button for the card being
controlled.

If no control is operated for 30 seconds, the controller reverts to its normal standby status, and the selected
card’s STATUS LED reverts to its normal operating mode.

3.3.2 Menu for local control

The ADC-1722 has operating parameters that may be adjusted locally at the controller card interface.
