Miranda ENC-1103 Installation Manual
ENC-1103
DESCRIPTION
The ENC-1103 is a high-quality encoder with 12-bit
conversion allowing operators to convert a SDI signal to
Composite, CAV or RGB. The composite outputs can be
NTSC, PAL or PAL-M and the component outputs can be
SMPTE, BETACAM or GBR formats. With its on-board
Genlock and Video Proc-Amp, the card provides flexible
system integration. An optional Frame Sync provides infinite
timing adjustment relative to an external reference. When
embedded audio is required to be separated into discrete
channels, the built-in audio demux (24-bit) allows up to 8
channels (2 groups) to be passed to an audio card. New
technology includes thumbnail generation and an optional
Waveform/Vectorscope over IP of the output signal which
allows operators to control and see the changes made to
the signal.
This card operates with the MSB-1121 Monitoring Switching
Bridge which allows the output of any module in the Densité
frame to be monitored.

INSTALLATION
Make sure you have ordered and received the ENC-1103
and its associated rear panel. If any of the following items
are missing, contact your distributor or Miranda
Technologies Inc.
* ENC-1103 SDI to Composite/CAV/RGB Encoder
* ENC-1103-SRP or ENC-1103-DRP Rear Panel (see
figure)
The ENC-1103 must be mounted in a DENSITÉ frame.
The installation includes both the ENC-1103 module, and
the rear panel module. It is not necessary to switch off
the power from these frames when installing or removing
the ENC-1103.
When used in conjunction with an audio module such as
the UAP-1781, the ABUS flat cable needs to be installed
between the ABUS connector of the ENC-1103 and the
connector of the audio module. The ABUS flat cable is
supplied with the audio module.
Detailed instructions for installing cards and their
associated rear panels in the Densité frame are given in
the Densité Frame manual.
Rear Panel Options
The ENC-1103 has different output types: composite,
CAV and RGB. Three composite outputs or one
CAV/RBG output is available on the single-width rear
panel; six composite outputs or two CAV/RGB outputs
are available with the double-width rear panel.
When a double-width rear panel has been installed, the
module must be installed in the right-most of the two slots
covered by the panel in order to mate with the rear panel
connectors. Should it be installed in the wrong slot, the
front panel LED will flash red. Move the card to the other
slot for correct operation. No damage will result to the
card should this occur.

OPERATION
Overview
The DENSITÉ frame incorporates a central controller
card, located in the center of the frame, it is equipped
with an LCD display and a control panel. The controller
handles error reporting and local and remote control for
all cards installed in the frame. The display and control
panel are assigned to the card in the frame whose
SELECT button has been pushed.
User Interface
Pushing the SELECT button will cause the on-card
STATUS LED to flash yellow, and the card identification
and the current status will be shown on the controller
card’s display. The STATUS LED will revert to it’s normal
state upon a second push of the button, or after a short
delay. The messages which may appear are shown in
the top line of the menu chart on page 3
Status Monitor LED
The status monitor LED is located on the front card-edge
of the ENC-1103 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 (which also
indicates fault reporting for this card on the DENSITÉ
frame’s serial and GPI interfaces).
A “Flashing Yellow” Status LED indicates that the
SELECT button on the front panel has been pushed, and
the controller display and control panel are now assigned
to this card.
The LED color assignments for some error conditions
can be reconfigured by the user (see the chart and menu
for details).

iControl Interface
The operation of the ENC-1103 may be controlled using
Miranda’s iControl system. This manual describes the
control panels associated with the ENC-1103 and their use.
Please consult the iControl User’s Guide for information
about setting up and operating iControl.
In iControl Navigator or iControl Websites, double-click on
the ENC-1103 icon to open the control panel.
Use the local control panel to access the detailed
status report shown in the STATUS menu below.
Green Yellow Red
Status Icons - At the top, to the left of the Miranda logo, are
five status icons that report various aspects of the card’s
operation:
(a) (b) (c) (d) (e)
(a) this icon shows whether manual card configuration of
this ENC-1103 is on [LOC] or off [REM]
(b) this icon reports the input format (525 or 625 lines)
(c) reference status – green if OK, red if an error has been
detected, white if the reference is absent, yellow if the
input is used as a reference
(d) Audio/video test – green during normal oper ation,
yellow (as shown) when Test Mode is activated
(e) ABUS multiple card configuration – green if
configuration and card setup are OK; red if there is a
mismatch between the ENC-1103 configuration and the
actual card setup
Move the cursor over an icon to see its current status in the
message area below the icons. If there is an error status,
the message will appear automatically. If there are multiple
error messages, the display will cycle through them

Thumbnail tab
Thumbnails are used to monitor the video output signal of the
ENC-1103. Streaming parameters are set using these controls.
ENABLE: OFF, VIDEO: enables thumbnail streaming or turn
streaming OFF
SIZE: SMALL, MEDIUM, LARGE: select the size of the Thumbnail
image.
PLAYER: OFF,THUMBNAIL: Click on the Thumbnail box to
enable the thumbnail Player. A window opens in the top section
and shows a thumbnail associated with the SDI video stream that
is being encoded by the ENC-1103.
• Note: you must check the VIDEO box in the ENABLE
section to see the video image.
Quality and Refresh Rate:
• Use the left-hand pulldown to select the video quality to
be sent by the streaming encoder. The choices are Poor,
Normal and HiQ (e.g. high quality).
• Use the right-hand pulldown to select the refresh rate for
the transmitted thumbnails. The choices are Fast, 1 sec,
2 sec, … 10 sec.
Streaming Priority Control: Click the Take control from Slot [##]
checkbox to force the Densité Controller for this frame to assign
more bandwidth for this card’s streaming output. Only one card in
the frame can use this feature. It has no effect unless you have
selected Fast for the refresh rate. The actual slot number of this
card, as shown in the window title bar, will appear when the
checkbox is ticked.
Blanking tab
Control over VBI data is achieved using this tab.
VBI: PROCESS, PASS, BLANK, LINE BY LINE: select whether
the overall VBI data field will be processed, will pass or be
blanked. If Line By Line is selected, use the right-side panel to set
each line individually.
LINE BY LINE: Available when Line by Line is checked in the
