FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The HDA-1832 is a reclocked high definition serial
digital video distribution amplifier. The HDA-1832
has one input, and 9 outputs, with automatic
equalization for up to 110 meters of cable (Belden
1694a) at 1.48 Gbps. The amplifier offers signal
presence detection and remote reporting, and
includes reclocking, providing an additional level of
signal integrity in long cable length applications.
While primarily designed for distribution of HD
serial digital signals (SMPTE 292M), the HDA-1832
automatically detects and re-clocks non-HD signals.
This multi-rate feature makes the HDA-1832 ideal
for applications where HD and SD signals may
coexist. The HDA-1832 is designed for use in the
DENSITÉ frame.

UNPACKING
Make sure the following items have been shipped
with your HDA-1832. If any of the following items are
missing, contact your distributor or Miranda
Technologies Inc.
* HDA-1832 HD/SD Reclocked Digital Video DA
* HDA-18NN-DRP or -SRP rear panel
INSTALLATION
The HDA-1832 must be mounted in a DENSITÉ
frame. The installation includes both the HDA-1832
module, and the rear panel module. It is not
necessary to switch off the frame’s power when
installing or removing the HDA-1832.
Detailed instructions for installing cards and their
associated rear panels in the Densité frame are given
in the Densité Frame manual.
Rear panel installation
Note that the HDA-1832 has nine outputs, and
making these available on BNC connectors at the
rear of the frame requires a double-width rear panel.
When a double–width rear panel is used, the module
must be installed in the right-most slot 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.
Should you require four or fewer outputs, you can
free up a slot in the frame for another card by using
the optional single-width rear panel HDA-18NN-SRP.
This panel brings outputs 1 to 4 to the four BNC
output connectors.
OPERATION
Overview
The HDA-1832 is equipped with an on-board LED
status indicator, mounted on the front edge of the
card so as to be visible from the front of the card
frame, even when the frame door is closed. The
functionality of this status monitor is described
below.The DENSITÉ frame incorporates a central
controller card, located in the center of the frame,
which is equipped with an LCD display. The card
handles error reporting and remote control for all
cards installed in the frame. The display shows the
error status of any card in the frame whose SELECT
button has been pushed.

The HDA-1832 is also equipped with the remote
reporting and control capabilities of the DENSITÉ
series. Fault reporting is carried out on a frame-wide
basis. There is no individual rear-panel access to the
fault and status reporting port of the HDA-1832.
Interfacing to the outside world is handled by the
frame’s contoller card. The fault reporting protocol is
standardized across the DENSITÉ series of modules.
Status Monitor LED
The status monitor LED is located on the front card-
edge of the HDA-1832 module, and is visible through
the front access door of the DENSITÉ frame.
This multi-color LED indicates module status by
color, and by flashing/steady illumination, according
to the following chart. The chart also indicates fault
reporting for this card on the DENSITÉ frame’s serial
and GPI interfaces.

NOTE: A “Flashing Yellow” Status LED indicates that
the SELECT button on the front panel has been
pushed, and the card is being accessed by the
controller. The LED color assignments for the various
error conditions can be reconfigured by the user.
User Interface
Push the SELECT button on the front edge of the
HDA-1832 to see a report of the current error status
on the DENSITÉ frame’s controller card display. The
HDA-1832 has three possible status messages:
STATUS
SIGNAL UNKNOWN – NO LOCK - NO SIGNAL - 143
Mb/s – 270 Mb/s – 360 Mb/s – 540 Mb/s – 1.48 Gb/s
NO REAR - SINGLE REAR - DOUBLE REAR
VERSION XXX
The STATUS LED will revert to it’s normal state upon
a second push of the button, or after a short delay
otherwise.
Example :
SELECT button pushed when the status LED is
green:
SELECT button pushed when there is no input
signal connected to the rear panel and the LED
is steady red:
The HDA-1832 has operating parameters which may
be adjusted using menus operated at the controller
card interface. After pressing the SELECT button on
the HDA-1832 card, use the keys on the local control
panel to step through the menu and adjust these
parameters. The menus, including the parameters
which can be adjusted, and the options which are
available, are shown on page 4.
CONFIG ALARM menu:
Allows the user to set the Status LED display for the
NO SIGNAL and NO LOCK conditions, and to
determine whether GPI alarms will be triggered.
FACTORY DEFAULT restores the HDA-1832 to the
factory set-up conditions, shown underlined in the
menu.
The use of the local control panel is described in
more detail in the controller card manual.
