INTRODUCTION/OVERVIEW
The multi-function Sigma DA5320 8 Channel Mixer/Router module is a member of the
Sigma 5000 series OctaStream™product line. The DA5320 is to be used in facilities utiliz-
ing AES digital audio signals requiring input gain and phase adjustment or where AES digi-
tal audio mixing and single channel routing is needed.
PRODUCT SCOPE
This module has the capability to perform two distinct functions -
1. As a member of the Sigma OctaStream™ product family, it includes the OctaBus™
TDM interconnect. This allows the DA5320 to function as a 64 X 8 channel AES
router utilizing a single input connector. Deformatting AES signals into single
channel streams along with distinct input/output channel assignment facilitates
channel-swapping across AES signals.
2. It has the capability to proportionally mix individual input channels into a single
output. Each output channel has an 8-channel mixer.

14811 • January 2005 • System Components
SYSTEM COMPONENTS
Frame
The DA5320 module is engineered to operate in a Sigma S5000 Signal Management
Frame. This frame provides all the necessary interface components and power for opera-
tion of the DA5320 module.
Interface Components
To accommodate a variety of connector requirements necessary for the signal formats
accepted by the S5000 Signal Management System, a number of backplanes are avail-
able. The DA5320 requires either an RP302 Twisted Pair I/O or RP303 BNC I/O Back-
plane.
Each S5000 Signal Management System frame is supplied with two (2) backplanes. The
required backplane(s) is specified at the time of order. If an existing frame does not have
the required backplane, replacement backplanes are available from Sigma Electronics and
can easily be installed in the field.
Power
The S5000 Signal Management System frame provides the required power to operate the
DA5320 via the backplane adapter. Dual power supplies are available for redundant appli-
cations.
Modules
The DA5320 consists of a single-slot card containing a front panel interface of switches,
indicator LED’s and a four-digit, seven-segment LED display. Via this interface all common
configuration settings and status indications are available to the user.
Optionally, if a CI5705 Communications Interface Adapter is installed in the S5000 Signal
Management System frame, the DA5320 may be configured and controlled from a remote
location via the EIA-485 port. The CI5705 is also necessary if an external video reference
is required.

14811 • January 2005 • Module Installation/Removal
MODULE INSTALLATION/REMOVAL
The DA5320 may be installed in any module slot in a S5000 Signal Management System
frame. Up to ten (10) modules of any type may be installed in the same frame. Modules
may be hot-swapped eliminating the need to power down the entire frame during replace-
ment.
Modules are held in place by a combination of the retention force of the cardedge connec-
tor pins and the motion restriction afforded by the proper installation of the frame front door.
Caution: For proper cooling, the frame door must remain closed. The door may
be opened for a short time, but irregular performance may occur. The
temperature and performance will stabilize again within 5 minutes after the door
is closed.
MODULE INSTALLATION
1. Verify that the appropriate backplane is installed in the frame.
2. Remove front door from frame.
3. Insert module into any slot associated with the appropriate backplane.
4. Holding knurled knob, push until module is completely seated in
cardedge connector on backplane.
5. Reinstall front door (required for proper operation of S5000 Signal
Management System frame - see Caution above).
MODULE REMOVAL
1. Remove frame front panel.
2. Firmly grasp knurled knob on front of module.
3. Pull module out of slot.
Connector Assignment
Because the flexibility of the S5000 Signal Management System frame allows a module to
be inserted into any slot position of an appropriate back plane (see Interface Components
above), the function of the back plane connectors will vary depending upon the module
inserted. The connector assignments for the DA5320 are shown in the following figure.

OPERATION
Front Panel Controls/Displays
The front panel, shown below, has three distinct functional areas - the Indicator LED’s
under the OctaStream logo on the right side; the switch controls, mostly on the left side and
the 7-segment display in the middle.
INDICATOR LED’S
LED’s are visible from the exterior of the frame when the front door is installed to accom-
modate checking the status of the modules without affecting the operating conditions within
the frame. The LED’s provide information about the status of three operating conditions -
error status, OctaBus™ status and power bus status.
1. ERROR - When this red LED is illuminated an invalid operating condition exists
within the DA5320. These errors fall into three categories - power-on self-test
failure, missing inputs or problems with the OctaBus™.
a. Power-On Errors - cycle the power to the unit.
b. Missing Inputs - The Error LED will illuminate when either the selected input
is unavailable or the defined reference signal is not present. To relieve this
condition, change the configuration information to specify a different source
or turn off the missing input.
c. OctaBus™ - If there are problems with the signal on the OctaBus the ERROR
LED will be illuminated and error messages can be accessed via the
Diagnostic menu.
2. OCTABUS - This green LED indicates the presence of a valid signal connected to
the OctaBus™ input BNC.
3. POWER - This green LED indicates the presence of suitable power being supplied
to the module by the power supply in the S5000 frame.

CONTROLS
SELECT BUTTON
The Select button is used to progress to a lower menu level. If pressed repeat-
edly, the display will always return to the idle display (see below) without making
any changes to any menu items. Pressing select after a data store (TAKE)
resets the menu to the level where the last option selection was initiated, allow-
ing the operator to perform similar operations on other channels or modify the
data just stored.
UP & DOWN BUTTON
The Up and Down buttons are used to toggle, up or down, through the available
menu options at the present level in the menu structure. Pressing an ARROW
button immediately after a valid data store (TAKE) will change the display to an
adjacent channel/selection for that parameter.
TAKE BUTTON
The Take button is used to store the current eligible data into memory. Display
data is only eligible for storage when the display is blinking. Pressing the TAKE
button immediately after a valid store will return the DA5320 to the idle display
(see below).
7-SEGMENT DISPLAY
The 7-segment display is used to display configurable menus items/parameters, provide
the current status of a configured parameter, display entry data for modification of config-
urable parameters and provide details about error conditions.
Typically, after the menu has been accessed and no more buttons have been pushed, the
display will return to the idle display after a short delay. The display can also be set to mon-
itor a single channel on a continuous basis to show its current delay.
Power-On Self Test (POST)/Idle Display
On power-up, the DA5320 runs a self-diagnostic routine. If the self-diag-
nostic routine is completed successfully, the DA5320 will display the idle
screen (shown on left). If the POST does not complete, verify that all
proper operating conditions exist in the frame, then cycle the power to
run the POST again. If it still does not complete, contact technical sup-
port as listed earlier in this manual.
IDLE DISPLAY
Page 7
14811 • January 2005 • Operation
Display Activation
To access menus when the Idle Display is showing, press any button.
Status Check
To check the current status of any parameter, activate the menu display and navigate
through the menu to the edit screen for the parameter of interest. The initial display will be
static, indicating the current data being held in memory for that parameter. If no additional
keys are pressed at this time the display will revert to its previously configured idle state
(Idle display or channel delay).
Parameter Configuration
Activate the menu display and navigate through the menu to the edit screen for the param-
eter to be configured. Pressing the UP or DOWN arrows will change the display to a new
value and it will begin to blink. Pressing the SELECT button at this point will abort the
change and return the display to the idle screen.
To record the parameter change requires that the TAKE button be pushed when the dis-
play is blinking. If there are multiple fields (characters) to be changed for a particular
parameter, each time the TAKE button is pressed the display will advance to the next field.
The new value for the parameter will be stored in memory only after all necessary fields
have been defined.

Configurable Parameters/Menu Items
Note: What follows is a discussion of the configurable parameters in the DA5320. To
view a diagram of the flow of the menu structure with simple operating instructions,
see the section of the manual entitled MENU STRUCTURE that follows this
discussion.
There are a number of items that are configurable on the DA5320. These fall into two basic
categories - Input Parameters and Output Parameters. Additionally, there are some diag-
nostic, reset and memory storage functions that can be accessed from the front panel
through the menu commands.
Input Parameters
Each DA5320 is an 8X8 AES Digital Audio router that can route the signals that are physi-
cally connected to it or any of the other 56 channels available on the OctaBus™. Which of
the available signals it should consider to be Inputs is defined under the
menu item.
With this menu item the operator defines, by selecting the OctaBus™ ID and the channel
number, exactly which signal on the OctaBus™ should be defined as each of the num-
bered inputs (1-8) to the module being configured, without regard to the physically con-
nected inputs to the module.
NOTE: If OctaBus™ is not enabled, requests for inputs defined as being from other
modules (OctaBus™ ID’s other than 1), will generate an ERROR condition.
Each of the defined inputs may also have a gain value assigned to them to adjust their
incoming level to the mixer or router stages. This gain adjust is adjusted via the
menu item that appears under the
main menu selection by specifying the gain factor
for each channel. The gain can be adjusted in 1 dB increments.
Output Parameters
Due to the nature of some of the parameters able to be modified, for example enabling out-
puts, it may be desired to change all or selected groups of outputs simultaneously. To
accommodate this, grouping of outputs is provided. Output grouping does not apply to rout-
ing functions in the DA5320 . Output grouping is the first parameter detailed in this section.
If the module being configured is to be a part of a system that utilizes the OctaBus™, this
feature must be activated. This feature is detailed in the OctaBus™ ID Assignment section
below.
To operate as a 64 X 8 channel router, the definiton of which of the defined inputs should
be routed to specific outputs must be detailed. As a mixer, which inputs will be mixed as
they are directed to the outputs must also be defined. Finally, the level of the signal to be
Page 9
14811 • January 2005 • Operation
sent to the ouput may be adjusted immediately prior to being sent to the output connector.
These features are detailed in the Output Channel Assignment/Mixing/Gain Control section
below.
The DA5320 has two additional features that are available to the user to assist in providing
quality I/O routing. It can be configured to provide V-fades in the event of data errors or
abrupt level changes caused by wiring or routing changes. It can also be configured to syn-
chronize the output timing to match an internal reference that is available to all modules in
the S5000 frame.
Output Grouping
To allow flexibility and convenience, the DA5320 can be configured to group output signals
with multiple channels having their configuration parameters modified simultaneously.
There are three different signal groupings available in the DA5320 that are set under the
output grouping menu
.
a. Independent
- Each channel’s parameters are set individually.
- Output pairs (as defined by the output settings) have their
b. Pair -
parameters set together. When the PAIR mode is active, only the odd
channels will appear as available menu selections when toggling through the
menu.
c. All -
- All outputs are simultaneously set for the same parameter. When
the ALL mode is active, toggling through channels on the menu is disabled.
OctaBus™ ID Assignment
To accurately identify the signals being put onto the OctaBus™ from multiple modules hav-
ing eight outputs, each module must have a unique module ID. This module ID is defined
via the
menu selection which is available as a submenu from the
main menu
item. The default ID for unconfigured modules is (1). If Octabus is not enabled or is not
being utilized, multiple modules in a system having identical Octabus ID’s is acceptable.
Anytime the channel designation requires an OctaBus™ ID, the display will show a decimal
between the last two characters - the next to last character being the OctaBus™ ID and the
last character being the channel number on the module specified by that OctaBus™ ID.
Page 10
14811 • January 2005 • Operation
Output Channel Assignment/Mixing/Gain Control
The
sub-menu item is used to configure the routing matrix of defined inputs to spe-
cific physical output connectors and the mixing operation of the DA5320. It is located under
the main menu item. When the menu item is initially selected, it displays the
current mix selection for the selected output.
This menu item also allows selection of which channels are to be mixed to create the spec-
ified ouput. When the screen that follows the menu item has data entered into
it, the actual channels to be mixed will be defined. If the data entered is 1:5.6, then Output
1 will consist of equal parts of input channels 5 and 6 (50% gain on each channel). If the
data entered into
were 1:5.-, then Output 1 would consist of only input channel 5 (“-”
is the selection for redundant input) with unity gain on channel 5.
The DA5320 is capable of much greater flexibility in its mixing operations when controlled
via the serial port on the rear of the S5000 frame. If a mix has been defined in this manner
that is not able to be displayed through the front panel selection, the display will show
indicating that the setting was made via the remote feature.
Each mixed signal may have a gain value applied to adjust the signal level sent to the
ouput connector. The gain is adjusted via the
menu item under
main menu
selection by specifying the gain factor for each output channel. The gain can be adjusted in
1 dB increments.
V-fades
The V-fade parameter enables the DA5320 to conceal AES framing errors that occur
upstream due to asynchronous switching or signal interruptions. With V-fade enabled, fast
error transitions (clicks and pops) are eliminated.
V-fades can be enabled through the
Output Synchronization
menu item in Set-up.
The internal reference signal used for output synchronization is introduced into the frame
through a connector on the rear panel of the S5000 Signal Management System frame
labeled Video Reference. This reference is distributed throughout the frame by the CI5705
Communications Interface located above the power supplies. The reference signal can be
Page 11
14811 • January 2005 • Operation
any valid NTSC or PAL video signal or AES Digital Audio. The DA5320 will match its ouptut
signal timing to be synchronized to this reference.
To have the DA5320 match its output signal timing to the internal reference the
menu setting must be set to ON.
Reset Type/Initiation
Occasionally it may be necessary, or convenient, to clear the data stored in memory by
resetting the DA5320. Because it may be desirable to erase only some of the data, there
are six different Reset levels available in the DA5320. They are labeled Input, Output, ALL
and Board. All reset options are accessed under the
menu item.
a. Input -
- resets the source of all inputs. Inputs will be set to the physical
inputs of the module, 1=1, 2=2, 3=3, etc.
b. Output -
- This type of reset clears all values stored defining the source
of the signal connected to each output. All values will be set correlating the
actual inputs of the module to its equivalent output, In 1 to Out 1, In 2 to Out
2, In 3 to Out 3, etc.
c. ALL -
- This type of reset clears all stored values defining every
parameter. on the module. This is a combination of all the previously defined
Reset functions.
d. BOARD -
- This type of reset includes all the capabilities of the ALL
reset but also toggles power to the board initiating the Power-On Self Test.
Diagnostic Data Display
If, at any time, the DA5320 encounters any anomalies with the data on the OctaBus, the
red, ERROR LED will be illuminated in the front panel and an error message will be stored
for display when the
reported under the
menu item is accessed. The OctaBus error categories to be
menu item are
A. OctaBus receive error 0
B. OctaBus state error
C. OctaBus receive error 1
To assist the technicians in the unlikely event of a service call, the
menu item will
display the version number of the software used to program the DA5320.
