Getting Started
Most CardModules are installed into the rack frames and system tested in the factory. If
this is an upgrade part or service exchange item then the module is supplied in a padded
cardboard carton which includes the CardModule, rear connection plate and mounting
screws.
Packaging
The shipping carton and packaging materials provide protection for the module during
transit. Please retain the shipping cartons in case subsequent shipping of the product
becomes necessary. Do not remove the module from its protective static bag unless
observing adequate ESD precautions. Please see below.
ESD Warning
This product is static sensitive. Please use caution and use preventative measures to
prevent static discharge or damage could result to module.
Preventing ESD Damage
Electrostatic discharge (ESD) damage occurs when electronic assemblies or the
components are improperly handled and can result in complete or intermittent failure.
Do not handle the module unless using an ESD-preventative wrist strap and ensure that it
makes good skin contact. Connect the strap to any solid grounding source such as any
exposed metal on the rack chassis or any other unpainted metal surface.
Caution
Periodically check the resistance value of the antistatic strap. The measurement should
be between 1 and 10 MOhms.

Note. Please check connected peripheral equipment before using the P DM 5280 to
make sure the audio ports of the P DM 5280 are configured correctly, e.g. an output
is not connected to an output of another device, this might damage the equipment.
Product Description
The P DM 5280 Module is a high performance SD/HD/3GBit/s audio embedder and
deembedder for AES digital audio streams.
Eight external AES ports are provided which can be switched by the user individually as
AES inputs or outputs. These AES ports are provided as balanced AES3 audio inputs or
outputs on a 25 pin SubD connector (P DM 5240 D) and as unbalanced AES3id audio
inputs or outputs on 75Ohm MiniDIN connectors (P DM 5280 U).
All deembedded and external AES input streams can be processed in an audio
processing stage incl. mono gain, stereo downmix, mute, overload and silence detection
as well as a 1kHz test tone generator.
DolbyE processing is included in the audio processing stage, i.e. one encoded DolbyE
stream can be synchronized to the SDI clock domain and the Guard Band is
automatically aligned.
The P DM 5280 DO / UO variants provide an optional optical SDI interface (RX/TX).
NOTE: The P DM 5280 is delivered from the factory preconfigured with 4 external AES
Inputs and 4 external AES outputs. See page 27 for information on re-
configuration of the signal direction of each AES port.
Key Features
•Support for SDTV, HDTV and 3GBit/s standards
•Automatic video standard and format detection
•Audio ports can be individually configured as inputs or outputs
•Existing embedded audio can be deembedded

Video Output Formats
Same as the input format, or the pre-selected format if no input is connected (see above).
Video and Audio Delay
The SDI output signal can be delayed up to 62 frames in steps of frames, lines and
pixels. This user delay effectively modifies the total processing time of the device (input to
output).
Audio content can also be adjusted independently from the video content. The audio
delay is always in reference to the video delay and can be negative to video, depending
on the video delay. Max. audio delay is 10 sec. in steps of single audio samples.

P DM 5280 Reference Manual. Rev 2.1
Page 9 of 34
Audio Processing
The module will de-embed the complete audio payload from the incoming SDI stream (4
AES groups = 8 AES streams = 16 mono channels), and passed to the AES audio
processing infrastructure, along with up to 8 external AES inputs.
The type of audio (PCM, DolbyE or Audio Data) is detected by the module automatically.
PCM Audio using the sample rate converters will be free from any audio interference
(“pops and clicks”) when frames are dropped or repeated by the frame synchronizer.
NOTE: If an encoded DolbyE audio signal is detected by the module the associated SRC
and the following audio processing will be switched off automatically. For
asynchronous DolbyE streams, the DolbyE functionality should be enabled on the
respective path. See page 24 for details.
Audio Embedding with No Video Input
With no SDI signal connected the module will switch to the last connected video standard
(default) and will produce a test pattern video output with the audio embedded.
The test pattern can be selected using the APPolo Controlsystem.
NOTE: It is possible to disable this automatic generation of an output SDI signal. When
this function is disabled, and no SDI input is connected, the SDI output will not
generate any signal at all.
If used in standalone mode with no SDI input connected, the output standard can be
changed from the default, so that it generates a free-running SDI stream in any standard.
See page 19for details. If the SDI video input is removed during operation, then the
embedder will continue to embed audio into a test pattern video frame in the selected
format until the video input is restored.
NOTE: The factory default setting is “default to the last connected video standard”. This
will be 1080i/50 for new modules when delivered from the factory. This can be
cleared by connecting a different video input, or by selecting the required video
format (using the selections provided). See page 32 for details on making
permanent changes to the device.

Connections
Video
The P DM 5280 uses standard 75 Ohm BNC connectors for SDI connectivity. We
recommend the use of high quality video cable for digital video connections to reduce the
risk of errors due to excessive cable attenuation. Max cable lengths the module will
support are shown below.
SDTV = 250m Belden 8281 (270Mbits/s)
HDTV = 140m Belden 1694A (1.4Gbits/s)
3GBit/s = 80m Belden 1694A (2.97Gbits/s)
NOTE: Due to the compact design of the connection plate it will be necessary to use a
connection tool to secure the BNC video connectors.
Audio
The module provides for both Unbalanced (AES3id on MINI DIN connectors) and
Balanced (AES3) external audio connections.
The P DM 5280 U/UO versions provide MiniDIN (DIN1.0/2.3) connections
for unbalanced AES3id
The P DM 5280 D/DO versions provide a SubD25 connector for balanced AES3
(pin layout see table below and Figure 8)

Optical Fiber
The P DM 5280 UO and DO versions provide LC/PC connectors for single mode fiber
cables (option). The fiber interfaces can be selected from a variety of different SFP style
modules. Also from all of the 18 CWDM wavelengths a SFP module can be selected.
Multimode fiber cables can be used also, but this will limit the max. fiber length to approx.
1km.
NOTE: Please take care that surfaces of fiber cables and LC connectors are always
protected against scratching and dust if not fiber cables are connected. Dust and/or
scratches will lead to high attenuation of the optical power transmitted.
Installation
If this module was supplied as part of a system it is already installed in the rack
enclosure. If the module was supplied as a field upgrade please follow the installation
procedure below.
NOTE Observe static precautions when handling card.
Please see ESD warnings on Page 7.
Each Card Module is supplied with a rear connection panel and mounting screws. Please
follow the procedure below for the installation of the card module into the Series 5000
Card Frame.
NOTE. This module should be installed in the R FR 5012 RackFrame with a Fan Front
Cover, to ensure sufficient airflow into the RackFrame.
We recommend you power the RackFrame down before installing any additional modules
into an existing RackFrame.
1. Select a free two slot space in the card frame where the CardModule will be
located.
2. Remove the blank connection panels from the rear of the rack (if fitted)
3. Install the rear connection panel using the screws supplied. Do not tighten the
screws fully
4. Slide the card module into the card frame and carefully check the CardModule
connects to the rear connection plate. The card should fit easily and should not
require excessive force to insert - if you feel any resistance, there could be
something wrong with the rear connection panel location. Do not try and force
the connection this may damage the connectors. Remove the rear connection
panel and check alignment with the CardModule.
5. Insert and remove the CardModule a few times to ensure correct alignment and
then tighten the two screws to secure the rear connection plate.
6. Power up the rack and check the module LED’s and matrix display illuminate.
Check the module is automatically logged into the control system device tree.
(It may take a few seconds for the control system to “discover” the new module)

Control System GUI
All LYNX CardModules support a computer interface which allows setting the modules
parameters using a simple GUI interface. Access to all standard features and in some
cases extended features is possible using this interface. The complex nature and
extensive user settings provided on the P DM 5280 requires the use of the control
system.
NOTE Any settings made using the control system overrides any local settings made on
the module. All settings are stored in internal flash ram and will survive power
cycles and long term storage.
Figure 11 shows the complete module GUI. The “Device Info” area across the top
contains information about the module including name and firmware revision. The
“Position” area displays the modules position and physical location. This is useful if the
device is installed as part of a larger installation.
NOTE: The Locate button (in the “Position” area) is a useful tool to quickly identify a
module in larger systems. Activating “Locate” will flash the module’s alarm LED in
yellow color. (this does not affect the module’s operation in any way).
This function will be stopped automatically (timeout).
The “Error Log” at the bottom of the screen displays an individual timestamp’ed message
for any error or warning condition in the system. The same information can always be
found in the APPolo Control System’s textual logfiles.
The primary GUI screens and functions are described in the following sections.

Overview
The MAIN Tab (Figure 12) visualizes the module’s functionality. The audio and video
signals are presented flowing from left to right. Selections are made using onscreen
sliders, radio buttons, drop down selections and checkboxes. The screen can be zoomed
in/out using the mouse-wheel or the navigation tool in the top left corner of the screen.
When zooming closer, the contents of the individual boxes will become visible.
Video Path
The SDI video input on the left can be selected
from the electrical (SDI) or from the optical (SFP)
input (Optical Versions only). Only one of these
two inputs can be used at any one time. See
Figure 13.
The chosen SDI input delivers its signal first to an
Audio Deembedder (for extraction of all contained
audio channels).
Blanking of the H- and V- interval (HANC / VANC)
can be enabled to completely remove all contents
form the respective ANC area.
The Auto-Test pattern section defines if a generated test-image shall be generated on the
output when no SDI input can be detected. If enabled, this test pattern will be generated
in the same standard that was last detected on the SDI input. The generated standard
can, however, be modified here.
NOTE: The standard of the generated SDI output can only be modified while there is NO
current SDI input detected. Furthermore: as soon as a valid SDI input is detected,
this setting will automatically fall back to the default setting “follow (last) input”.
The Embedder will embed the specified groups into the SDI output stream, replacing an
existing Audio Group, if already present. The resulting output SDI stream is available on
both an electrical (BNC) as well as an optical (SFP) connector, if available.

Audio Routing
All 8 AES channels are deembedded from the SDI input. In addition, up to 8 external AES
inputs can be used. This makes a total of up to 16 AES inputs that can be processed and
then assigned to any one of the outputs (SDI embedder and up to 8 external AES
outputs). Further details can be found in the following sections.
NOTE: there are a total of 8 external AES ports. Each of the port can be configured to be
an input or an output port. See page 27.
flexGUI path highlighting and signal patching
The flexGUI shows all current signal connections as lines (i.e. it does not show any signal
lines that are actually unused dead ends). Hovering the mouse pointer over any such
signal line will highlight the complete signal path that leads to this point. This illustrates
clearly where the particular signal is coming from. Similarly, the downstream path is
highlighted to show where this signal is going to.
To re-connect a signal (change the routing) you can think of a signal line as a patch-cable
that has to be connected to the desired source. Hovering the mouse-pointer over a
flexible signal will show a handle. Grab the handle (click-and-hold) with the left mouse
button and drag-and-drop it to the new desired source. More details are shown below.
Timing and Delays
Different internal processing paths for audio and video signals require different internal
processing times. Independently from these internal processing delays, a sophisticated
algorithm will make sure that all signals that are received on the input will be delivered
from the outputs in the exact same relative timing.
As an example, embedded audio streams, which are separated from the video by the
audio-deembedder near the input, and which are then routed on internal channels that
are independent and separate from the video infrastructure, will be embedded back into
