Model 5422A
DANTE INTERCOM AUDIO ENGINE
1 no longer is routed to the output. When the high-
frequency control tone is no longer present the switch -
ing action reverses.
Channel Level Adjustment and
Labeling
The nominal level of each Dante receiver (input)
channel and Dante transmitter (output) channel can
be individually adjusted. This would apply to the 32
channels associated with the Model 5422A-01 and the
64 channels with the Model 5422A-02. The adjustment
range is ±20 dB in 1-dB steps. This capability can be
useful when using a Model 5422A to interface various
pieces of equipment that may have different internal
operating levels.
The Model 5422A includes extensive capabilities to
allow the labeling (naming) of Dante audio channels.
This can help ensure that the specific configuration
selected for a Model 5422A can be understood by other
technical personnel. In this way, changes to channel
labels won’t require the use of the Dante Controller
application although the labeling conventions are, of
course, fully compatible.
Flexible Networking Capability
Using the Dante Controller application program, the
Model 5422A’s three Gigabit Ethernet ports can be
selected to operate in one of four modes: Switched,
Redundant, SMgmt, and ReMgmt.
This should allow virtually any desired networking
implementation to be easily achieved.
In the Switched mode a single Ethernet connection to
either of the Model 5422A’s two Dante Ethernet ports
will provide connectivity to the associated Dante net-
work. The remaining Dante Ethernet port will provide
Dante network “loop-through” capability and can be
used to interface with another piece of Ethernet-con -
nected equipment. The management Ethernet port will
be used to access the Model 5422A’s monitoring and
configuration webpages.
In the Redundant mode two independent Ethernet
connections are made to the Model 5422A’s two Dante
Ethernet ports, enabling Dante’s redundant network -
ing capability. Again, the management Ethernet port
will be used to access the Model 5422A’s monitoring
and configuration webpages. Using either of these
network modes allows separate network connections
to be maintained for Dante audio and management
purposes.
In the SMgmt mode a single Ethernet connec -
tion is used for both Dante audio functionality as well
as providing access to the Model 5422A’s manage-
ment webpages. The remaining Dante Ethernet port
will provide network “loop-through” capability and can
be used to interface with another piece of Ethernet-
connected equipment.
In the ReMgmt mode two Ethernet connec
-
tions can be made to the Model 5422A’s two Dante
Ethernet ports. This will allow independent audio net -
working capability for redundant Dante applications.
Access to the Model 5422A’s management webpages
will be made by way of the Ethernet connection made
to the primary Dante Ethernet port.
Operating Power
The Model 5422A allows an AC mains source of 100-
240 V, 50/60 Hz to be directly connected. It can also
be powered using a 10-18 volts DC source that is con-
nected via a broadcast-standard 4-pin XLR connector.
If both AC and DC power sources are connected to a
Model 5422A, the unit will be powered by the AC mains
supply. Only if the AC mains source fails will a load be
placed on the DC source. This allows a source of DC,
typically a battery pack, to serve in a backup capacity.
With this arrangement normal operation can continue
even if AC mains power is lost.
Updating and Future Capabilities
The Model 5422A was designed so that its capabilities
can be enhanced in the future. A USB connector, locat-
ed on the unit’s back panel, allows the Main and FPGA
firmware (embedded software) to be updated using a
USB flash drive. The Model 5422A uses Audinate’s
Brooklyn module to implement Dante. The firmware
in this module can easily be updated using the Dante
Updater application that is included with the Dante
Controller application. All software files and configu -
ration parameters are stored in non-volatile memory.
Installation
In this section, the Model 5422A will be mounted in
one space (1U) of an equipment rack. Up to three
Ethernet data connections will be made using standard
RJ45 patch cables. AC mains and/or DC power will
be connected to the Model 5422A. AC mains power
