are somewhat subtle, the two modes al-
low distinct applications to be supported.
In the momentary mode the button can
provide a combination talkback function.
This would be applicable for on-air sports
applications where the microphone signal
typically remains active. In the latching
mode the button could be considered
as serving as a microphone-on/off con-
trol. This would be useful in applications
where talent requires local control of their
microphone on and off status. The inte-
grated sidetone function can be enabled
or disabled as required. This is important
as different applications may, or may not,
provide “mix-minus” talent cue signals.
In the case where no mix-minus signal is
present, providing a Model 380 user with
sidetone is an important means of con-
firming their local microphone audio.
Ethernet Data and PoE
The Model 380 connects to an Ethernet
data network using a standard 100 Mb/s
twisted-pair Ethernet interface. The physi-
cal interconnection is made by way of a
Neutrik® etherCON RJ45 connector. While
compatible with standard RJ45 plugs,
etherCON allows a ruggedized and lock-
ing interconnection for harsh or high-
reliability environments. An LED displays
the status of the network connection.
The Model 380’s operating power is
provided by way of the Ethernet interface
using the 802.3af Power-over-Ethernet
(PoE) standard. This allows fast and ef-
ficient interconnection with the associated
data network. To support PoE power man-
agement, the Model 380’s PoE interface
reports to the power sourcing equipment
(PSE) that it’s a class 1 (very low power)
device. If a PoE-enabled Ethernet port
can’t be provided by the associated Ether-
net switch a low-cost PoE midspan power
injector can be utilized.
Future Capabilities and
Firmware Updating
The Model 380 was designed so that its
capabilities and performance can be en-
hanced in the future. A USB connector,
located on the unit’s main circuit board
(underneath the unit’s cover), allows the
application firmware (embedded software)
to be updated using a USB flash drive.
The Model 380 uses Audinate’s Ultimo™
integrated circuit to implement the Dante
interface. The firmware in this integrated
circuit can be updated via the Ethernet
connection, helping to ensure that its
capabilities remain up to date.
Getting Started
What’s Included
Included in the shipping carton are a
Model 380 On-Air Beltpack and a printed
copy of this guide. As a device that is
Power-over-Ethernet (PoE) powered,
no external power source is provided.
Should a PoE midspan power injector be
required it must be purchased separately.
Connections
In this section signal interconnections
will be made using the four connectors
located on the bottom of the Model 380’s
enclosure. An Ethernet data connection
with Power-over-Ethernet (PoE) capability
will be made using either a standard RJ45
patch cable or an etherCON protected
RJ45 plug. A microphone will be connected
