if AES67 mode is enabled then PTPv2 will
be utilized and the Dante transmitter (out-
put) channels will use multicast. The sam-
ple rate will be fixed at 48 kHz.
Preferred Clock Source
By the very nature of its intended applica-
tion, the Model 5401A will normally serve
as the Leader Clock for all Dante-enabled
devices. The unit has the ability to com-
municate with the Dante network, selecting
itself as the Preferred Leader and causing
the Enabled Sync to External function to
be enabled. The status of these two pa-
rameters can be observed using the Clock
Status function in Dante Controller.
Settings accessible using the Model
5401A’s management webpages allow ex-
tensive changes to the clock configuration.
These are provided for use when trouble-
shooting or addressing special applications.
In most cases, the Model 5401A’s default
settings would be appropriate and should
be utilized.
Model 5401A
Configuration
Many Model 5401A Dante Leader Clock
operating parameters can be configured
using the management system’s webpages
that are provided by way of one of the unit’s
Ethernet ports. The specific port utilized for
management will depend on the network
configuration that is selected using the
Dante Controller application. A standard
web browser is all that is required to utilize
the menu webpages.
Several key network configuration param-
eters can also be viewed and revised using
the Model 5401A’s front-panel graphics dis-
play and associated pushbutton switches.
Refer to Appendix D for details on which
parameters can be revised in this manner.
Management IP Address
It’s easy to identify the Model 5401A’s man-
agement IP address by way of the front-
panel display. If the screen saver function
is active, as it will be in most situations,
one of the five pages that will automatically
display will show the current management
IP address. As such, a user can simply
observe the sequencing menu pages and
watch for the one that displays the cur-
rent management IP address. If it’s desired
that the current management IP address
be continuously displayed then the Enter
pushbutton switch on the front panel should
be pressed. This will stop the screen saver
function and cause the current manage-
ment IP address to display. It will also allow
the various menu pages to be accessed
using the up, down, left, and right pushbut-
ton switches. Simultaneously pressing the
left and right arrow buttons will cause the
screen saver mode to begin again. The
screen saver mode will also automatically
start two minutes after the last press of any
of the front-panel pushbutton switches.
How the management Ethernet port obtains
its IP address will depend on the manage-
ment interface configuration setting. The
default method is automatic so the Model
5401A’s management port will first try to
obtain an IP address using DHCP. If that
is not successful an IP address will be
assigned using the link-local protocol. An
address of 169.254.x.x will indicate that an
IPv4 address was established using link-lo-
cal. The Model 5401A may also have been
configured to use a manual (fixed or static)
IP address. The front-panel display and as-
sociated pushbuttons, or the Model 5401A’s
management webpages, can be used to re-
view and/or make changes to the manage-
ment IP address and related parameters.
