Model 5422A
DANTE INTERCOM AUDIO ENGINE
can be connected by means of a detachable cord that
is compatible with the unit’s 3-pin IEC 320 C14 inlet
connector. Some applications may warrant connection
to a source of nominal 12 volts DC which can be made
by way of a 4-pin XLR connector. A DC source can be
used to power the Model 5422A as well as serving as a
backup power source should AC mains not be present.
What’s Included
The shipping carton contains a Model 5422A Dante
Leader Clock and instructions on how to obtain an elec-
tronic copy of this guide. Also included in the shipping
carton is a North-American-standard AC mains cord.
For destinations outside of North America the local
reseller or distributor should provide an appropriate
AC mains cord.
Mounting the Model 5422A
The Model 5422A Dante Leader Clock requires one
space (1U) in a standard 19-inch (48.3 cm) equipment
rack. Secure the unit into the designated equipment
rack using two mounting screws per side. As the Model
5422A does not contain a fan or other noise-producing
source it can be located within a room or other structure
where audio monitoring is going to take place.
Twisted-pair (UTC) Ethernet has a 100-meter (325-
foot) interconnection cable limitation. But that can
be overcome by using fiber-optic interconnections
between the Model 5422A and the Ethernet switch
or switches in the one or more associated local-
area-networks (LANs).
Ethernet Connections
The Model 5422A provides three Gigabit Ethernet
(GigE) ports for flexibility and compatibility with many
networking implementations. Two ports are provided
for interconnections with one or two local area networks
(LANs) associated with Dante audio-over-IP networking
schemes. They are labeled as PRI (primary) and SEC
(secondary). The third Ethernet port, labeled MGMT,
can be used to access the Model 5422A management
resources. An internal web server function supports the
Model 5422A’s management port’s webpages. These
webpages are used for configuration, monitoring,
and maintenance of Model 5422A operation. Refer to
Figure 2 for an overview of the Model 5422A’s three
Ethernet ports and how they can operate.
Using the Dante Controller application, the three
Ethernet ports can be configured to operate in one of
four modes: Switched, Redundant, SMgmt, or
ReMgmt. If configured for either the Switched
or Redundant modes the management webpages are
accessed by way of the management Ethernet port.
When configured for the SMgmt mode the
management webpages are accessed by way of either
the primary or secondary Ethernet port. When config
-
ured for the ReMgmt mode the management
webpages are accessed using an Ethernet connection
made to the primary Ethernet port.
By providing three Ethernet ports and four configuration
modes, the Model 5422A allows support for virtually
all facilities, including those that utilize separate
networks for Dante audio transport and equipment
management. In this way, “production” networks that
support transport of audio signals by way of a single
LAN (Switched mode) or two LANs (Redundant mode)
can be separate from an engineering network that is
used by technical personnel for configuring and main
-
taining a facility or “plant.”
Connections to the three Ethernet interfaces are made
by way of standard RJ45 jacks that are located on the
back of the Model 5422A’s enclosure. The Ethernet
interfaces support auto MDI/MDI-X so that cross
-
over cables are not required. Refer to Appendix A for
examples of how the Model 5422A’s three Ethernet
interfaces might be utilized. This topic is also covered
in detail in the Dante Configuration section. It’s difficult
