Studio Technologies, Inc. Model 5401A Dante Leader Clock, Issue 4, Page 4
In the Redundant+Mgmt mode two independent Ethernet
connections can be made to the Model 5401A’s two Dante
Ethernet ports. This will enable Leader clock capability for
applications that utilize Dante redundancy. Access to the
Model 5401A’s management webpages will be made by
way of the Ethernet connection made to the Dante primary
Ethernet port.
Operating Power
The Model 5401A allows an AC mains source of 100-240
V, 50/60 Hz to be directly connected. It can also be DC
powered using a 10-18 volt source that is connected via a
broadcast-standard 4-pin XLR connector. If both AC and DC
power sources are connected the unit will be powered by
the AC mains supply. Only if the AC mains source fails will
appreciable power be drawn from the DC source. This allows
a source of DC, typically an external power supply, to serve
in a backup capacity. With this arrangement normal operation
can continue even if AC mains power is lost.
Future Capabilities
The Model 5401A was designed so that its capabilities can
be enhanced in the future. A USB receptacle located on the
unit’s back panel, allows the three firmware files (embedded
software) to be updated using a USB flash drive. The Model
5401A’s Dante firmware can be updated using one of the unit’s
Ethernet connections, helping to ensure that the Dante capa
-
bilities remain up to date. All software files and configuration
parameters are stored in non-volatile memory.
