Model 5204
Dual Line Input to Dante Interface
Ethernet Data and PoE
The Model 5204 connects to a data net-
work using a standard 100 Mb/s twisted-
pair Ethernet interface. The physical
interconnection is made by way of a
Neutrik® etherCON RJ45 connector.
While compatible with standard RJ45
plugs, etherCON allows a ruggedized and
locking interconnection for harsh or high-
reliability environments. An LED displays
the status of the network connection.
The Model 5204’s operating power is
provided by way of the Ethernet interface
using the Power-over-Ethernet (PoE) stan-
dard. This allows fast and efficient intercon-
nection with the associated data network.
To support PoE power management, the
Model 5204’s PoE interface reports to the
power sourcing equipment (PSE) that it’s
a class 3 (mid power) device. An LED is
provided to indicate when power is being
supplied to the Model 5204. Note that no
provision has been made to allow an exter-
nal power source to be connected. Howev-
er, if the associated Ethernet switch does
not provide PoE capability a commonly-
available mid-span PoE power injector
can be utilized.
Dedicated Charging Port
(DCP)
A unique resource is the Model 5204’s
dedicated charging port. Using a standard
USB type A receptacle, the port has a
5 volt output with a maximum current of
approximately 1 amp. This nominally
5 watt output should be sufficient to rapidly
charge a personal audio player, smart-
phone, or tablet device. An auto-detect fea-
ture supports divider mode, short mode,
and 1.2 V/1.2 V charging modes. Besides
charging, the port can allow a connected
device to continuously send audio to the
associated Dante network without requiring
an external power source. Note that in this
situation interfacing a device with the Model
5204 requires separate cables, one for the
analog audio source and one for powering/
charging.
One note of interest: the dedicated charg-
ing port derives its power from the Ethernet
with Power-over-Ethernet (PoE) connec-
tion. While the Model 5204’s audio and
data circuitry takes very little energy, the
dedicated charging port can source up to
approximately 5 watts. As such, the Model
5204’s Ethernet interface will identify itself
to upstream power-sourcing-equipment
(PSE), typically an Ethernet switch with
integrated PoE, as a PoE class 3 powered
device (PD).
Dante Audio-over-Ethernet
Audio data is sent from the Model 5204
using the Dante Audio-over-Ethernet media
networking technology. As a Dante-com-
pliant device, the Model 5204’s two audio
channels can be assigned to other devices
using the Dante Controller software appli-
cation. Bit depths of up to 24 and sample
rates of 44.1, 48, 88.2, and 96 kHz are
supported. Two bi-color LEDs provide an
indication of the Dante connection status.
The Model 5204 uses Audinate’s Ultimo™
integrated circuit for implementing Dante.
The integrated circuit’s firmware can be
updated via the Ethernet connection, help-
ing to ensure that its capabilities remain up
to date.
