5. CARD EDGE CONTROLS
The 7721AE4-HD is equipped with an 8 position DIP switch to allow the user to select various functions.
All positions are assigned sequentially such that the first position is located at the left side of the DIP
switch (farthest from to the card ejector). When the switches are set to Off the LED status indicators near
the DIP switch indicate the presence of the AES audio. When other DIP switch combinations are
selected, various operation modes of the module can be set using the toggle switch. The LED Mode
indicators near the DIP switch indicate the settings of each of these modes as shown in Table 4-1. The On
position is down, or closest to the printed circuit board. Sections 5.1 to 5.8 show the assigned DIP switch
functions.

5.1. SELECTING THE AUDIO GROUPS THAT WILL BE EMBEDDED
The SMPTE 299M standard permits up to 4 groups of 4 audio channels to be embedded into the 270 Mb/s
video bitstream. Model 7721AE4-HD has two separate embedders that will embed up to four audio
channels (two AES pairs) into one of the groups. The Embedders can be treated as two independent
embedders for unrelated audio content or can be locked together where the audio in both groups is related
and hence its phase must be maintained (for example, 5.1 surround sound audio).
" Some legacy equipment may not be compatible with two embedded audio groups
present in the video stream.

7700 MultiFrame Manual
7721AE4-(B)-HD HDTV 4 Channel AES Audio Embedder
Page-10 Revision 1.5
The source for Embedder A is the audio coming in on the AES IN 1 and 2 connectors. The source for
Embedder B is the audio coming in on the AES IN 3 and 4 connectors. There are separate DIP switch
settings that are used to enable or disable each embedder as well as to set the audio groups where the
embedders will place the audio on the SDI output.
When the DIP switches are set as shown in Table 5-2, the toggle switch is used to enable or disable
Embedder 1. Each time the toggle switch is pressed up or down the Embedder 1 Enable mode will
change as indicated by the LEDs in Table 5-2.
When set to Disable, embedder 1 will be disabled. When set to Enable, the embedder destination can be
set when the DIP switches are set as shown in Table 5-3. Channels 1 and 2 from AES input 1 will be
embedded into channels 1 and 2 of the selected group. Channels 1 and 2 from AES input 2 will be
embedded into channels 3 and 4 of the selected group. If audio is not present on one or both of the AES
inputs, the respective channels of the selected audio group will be mute.

When Clean and embed is selected, all incoming HANC packets and embedded audio data will be
removed; and new audio data will be embedded after EAV. The remaining H blanking period is filled with
default blanking value.
When Reformat and embed is selected, pre-existing embedded audio contents will be extracted. All
packets with "Marked Packet for Deletion" or containing the same selected audio groups that are selected
for embedding will be removed. The remaining packets are left justified and new audio will be embedded
after these packets.
5.4. SELECTING AES LOCKED GROUP MODE
For audio that is synchronous to video there is exactly 8008 audio samples (48kHz sampling rate) in 5
frames of NTSC, 525 line video. Most audio embedders will spread these samples as evenly as possible
throughout the 5 frames of video. Because the 8008 samples do not divide evenly into 5 frames of video,
there is a sequence that only repeats every 5 frames. In all video standards it is possible for the phase of
the audio being embedded by two separate embedders to be out of phase with respect to each other. In
order to transport 8 channels of audio (4 AES pairs) through an embedded link with exactly the same
delay on each channel, both the embedder and the de-embedder must lock the FIFOs of both groups of
audio together. Failing to do so will cause a phase difference between the audio from the two groups.
When the DIP switches are set as shown in Table 5-8, the toggle switch is used to select whether the
embedders will be operated separately or locked together for embedding related audio (such as 5.1
surround sound).

Table 5-8: Lock Group Mode Switch Settings
When Independent group mode is selected, Embedder 1 and Embedder 2 are operated independently of
each other as if two separate embedder devices are being used. The FIFOs are not locked together and
the output phases of the two groups of embedded audio do not have any specific relationship to each
other.
When Locked group mode is selected, the Embedder FIFOs are locked together maintaining the phase
relationship between all 4 AES channel pairs in the embedded audio.
"
To maintain a guaranteed audio phase relationship through a complete SDI link, the
audio de-embedder MUST also provide the same locked FIFO management
functionality.
"
For firmware releases 2.3 build 3 and newer, Locked Group mode is ALWAYS active
regardless of the DIP switch setting. Changing the settings will have NO effect on
the mode.

When the Sample Rate converters are Enabled, the AES inputs are sample rate converted at 48 kHz
which is synchronous to the input video. AES inputs can be either synchronous or asynchronous to the
video source.
When the Sample Rate converters are Disabled, the content of AES inputs is preserved without any loss,
and directly embedded into the input video. AES inputs must be synchronous to the video source. This
setting is required when embedding Dolby E.
5.6. SELECTING FUNCTION OF THE MODULE OK STATUS LED

6.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
FRAME STATUS: The FRAME STATUS jumper located at the front of the module determines whether
local faults (as shown by the Local Fault indicator) will be connected to the 7700FR
frame's global status bus.
To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this
jumper in the On position. (Default)
When this jumper is installed in the Off position, local faults on this module will not be monitored.
6.2. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
UPGRADE: The UPGRADE jumper J16 located at the front of the module is used when firmware
upgrades are being done to the module. For normal operation it should be installed in
the RUN position. See the Upgrading Firmware chapter in the front of the binder for
more information.
To upgrade the firmware in the module unit pull it out of the frame. Move Jumper J16
into the UPGRADE position. Install the Upgrade cable provided (located in the vinyl
pouch in the front of this manual) onto header J24 at the card edge. Re-install the
module into the frame. Run the upgrade as described in Upgrading Firmware chapter
in the front of the binder. Once the upgrade is complete, remove the module from the
frame, move J16 into the RUN position, remove the upgrade cable and re-install the
module. The module is now ready for normal operation.

REMOTE MONITORING/CONTROL
7.1. WHAT IS VISTALINK
®
?
VistaLINK
®
is Evertz’s remote monitoring and configuration platform which operates over an Ethernet
network using Simple Network Management Protocol (SNMP). SNMP is a standard computer network
protocol that enables different devices sharing the same network to communicate with each other.
VistaLINK
®
provides centralized alarm management, which monitors, reports, and logs all incoming alarm
events and dispatches alerts to all the VLPro Clients connected to the server. Card configuration through
VistaLINK
®
PRO can be performed on an individual or multi-card basis using simple copy and paste
routines, which reduces the time to configure each module separately. Finally, VistaLINK
®
enables the
user to configure devices in the network from a central station and receive feedback that the configuration
has been carried out.
There are 3 components of SNMP:
1. An SNMP manager, also known as a Network Management System (NMS), is a computer running
special software that communicates with the devices in the network. Evertz VL-Fiber demo Manager
graphical user interface (GUI), third party or custom manager software may be used to monitor and
control Evertz VistaLINK
®
enabled fiber optic products.
2. Managed devices, (such as 7721AE4-HD), each with a unique address (OID), communicate with the
NMS through an SNMP Agent. Evertz VistaLINK
®
enabled 7700 series modules reside in the 3RU
7700FR-C MultiFrame and communicate with the manager via the 7700FC VistaLINK
®
frame controller
module, which serves as the Agent.
3. A virtual database, known as the Management information Base (MIB), lists all the variables being
monitored, which both the Manager and Agent understand. Please contact Evertz for further
information about obtaining a copy of the MIB for interfacing to a third party Manager/NMS.
For more information on connecting and configuring the VistaLINK
®
network, see the 7700FC Frame
Controller chapter.
