Model 5402
DANTE LEADER CLOCK WITH GNSS SYNCHRONIZATION
be used for Dante audio and the third for connecting to a
network designated for device management purposes. It’s
also possible to access the Model 5402’s management
webpages using the Dante Ethernet ports. The Model
5402’s Dante ports are labeled PRI and SEC indicating
that they are typically used for the primary and secondary
connections. The third Ethernet port is labeled MGMT, indi-
cating that it is intended for use accessing the management
webpages. How these three Ethernet ports function can
be selected in the Network Config – Switch Configuration
section of Dante Controller. The choices are Switched,
Redundant, SMgmt, and ReMgmt.
If Switched is selected then the Model 5402 can establish
one Dante audio connection with an Ethernet network. It
doesn’t matter which RJ45 jack is utilized, although for clar-
ity this would typically be the primary jack. The secondary
RJ45 jack can be used to interconnect with another piece
of networked equipment. The management Ethernet port
will be used to access the management webpages.
If the Model 5402’s Dante network is configured for
Switched ensure that only one of the two Dante RJ45 jacks
on the back panel is connected to the LAN associated with
the Dante network. If both of the Model 5402’s Dante RJ45
jacks are routed to ports on the same LAN this will typically
“crash” the network! (Although some of the latest/most-
advanced Ethernet switches will automatically detect and
prevent such a “network bridging” issue from occurring.)
If SMgmt is selected the same issues as discussed
in the previous two paragraphs would again apply. The
only difference is that the management webpages would
be accessed using the same Dante Ethernet port that is
being used to access the Dante network. The management
Ethernet port will be disabled.
If Redundant is selected then Dante’s Redundant net-
working capability will be enabled. In this case, separate
Ethernet LAN connections should be made to the Dante
primary and Dante secondary RJ45 jacks. Again, the Model
5402’s separate management Ethernet port will be used to
access the management webpages.
If ReMgmt is selected in Dante Controller then the
network connection made to the Dante primary Ethernet
port will also be used to access the management web-
pages. The Model 5402’s separate management port will
be disabled.
IP Addresses
When a Model 5402 has been configured for either the
Switched or SMgmt network mode a single Dante
IP address will be associated with the network connec-
tion that is made to either the Dante primary or the Dante
secondary RJ45 jack. If the network configuration has been
selected for Redundant or ReMgmt then separate
IP addresses and related network parameters will be as-
signed to the Dante primary and Dante secondary Ethernet
ports. No matter what network mode has been selected
the Model 5402 will always have a separate management
IP address.
Typically, the Model 5402’s Dante IP address or addresses
and related network parameters will be determined auto-
matically using DHCP or, if that’s not available, the link-local
network protocol. If desired, the Dante Controller applica-
tion does allow Dante IP addresses and related network
parameters to be manually set to a fixed (static) configu-
ration. While this is a more-involved process than simply
letting DHCP or link-local “do their thing,” if fixed addressing
is necessary then this capability is available.
Note that if the Model 5402’s network configuration has
been set for Redundant or ReMgmt then the
Dante primary and Dante secondary IP addresses and
related parameters can be independently configured. This
allows both Dante interfaces to be configured automatically,
both interfaces to be configured manually, or one interface
to be configured automatically and the other to be config-
ured manually.
By default, the Model 5402’s management IP address
and related network parameters will be determined auto-
matically using DHCP or link-local. A configuration option,
accessible using the front-panel display and associated
buttons or the management webpages, allows manual
control of the management IP address, subnet mask, and
gateway address values.
AES67 Configuration – AES67 Mode
Dante Controller allows a Model 5402 to be configured for
AES67 operation. This requires the AES67 mode to be set
for Enabled. As previously noted in this guide, if AES67
mode is enabled then PTPv2 will be utilized and the Dante
transmitter (output) channels will use multicast. The sample
rate will be fixed at 48 kHz.
Preferred Clock Source
By the very nature of its intended application, the Model
5402 will normally serve as the Leader Clock for all Dante-
enabled devices. The unit has the ability to communicate
with the Dante network, selecting itself as the Preferred
Leader and causing the Enabled Sync to External func-
tion to be enabled. The status of these two parameters
can be observed using the Clock Status function in Dante
Controller.
Settings accessible using the Model 5402’s management
webpages allow extensive changes to the clock configura-
tion. These are provided for use when troubleshooting or
