RJ45 plugs, etherCON allows a ruggedized
and locking interconnection for harsh or
high-reliability environments. The Model
48D’s operating power can be provided by
a Power-over-Ethernet (PoE)-compliant
Ethernet signal that’s connected to the
Model 48D’s Network A interface. For net-
work management purposes the interface
will report to the power sourcing equipment
(PSE) that it is a class 1 (very low power)
device. If PoE is not available the unit can
also be powered using an external source
of 12 volts DC.
Simple Installation
The Model 48D is housed in a rugged yet
lightweight aluminum enclosure that is de-
signed to be “field tough.” It can be used as
a standalone portable unit, supporting what’s
known in the broadcast world as “throw-
down” applications. Optional rack-mounting
installation kits are available to allow one or
two units to be mounted in one space (1U)
of a standard 19-inch rack enclosure. As
previously mentioned the Model 48D uses
standard connectors to allow fast and conve-
nient interconnections. Two Ethernet signals
are connected using Neutrik etherCON RJ45
receptacles. Operation will commence im-
mediately if Power-over-Ethernet (PoE) is
available on the Ethernet connection associ-
ated with the Network A interface. A 12 volt
DC power source can also be connected by
way of a 4-pin XLR connector.
Future Capabilities and
Firmware Updating
The Model 48D was designed so that its
performance and capabilities can be en-
hanced in the future. A USB connector,
accessible on the unit’s back panel, allows
the main firmware (embedded software)
to be updated using a USB flash drive.
To implement its Dante interfaces the Mod-
el 48D uses two of Audinate’s Ultimo™
integrated circuits. The firmware in these
integrated circuits can be updated via the
unit’s two Ethernet connections, helping to
ensure that the Dante capabilities remain
up to date.
Getting Started
In this section signal interconnections will
be made using the connectors located on
the Model 48D’s back panel. Two Ethernet
data connections will be made using either
standard RJ45 patch cables or etherCON
protected RJ45 plugs. The unit can be
powered using an Ethernet connection
that provides Power-over-Ethernet (PoE).
If that is not available a 4-pin XLR connec-
tor allows the connection of an external
source of 12 volts DC.
System Components
Included in the shipping carton are the
Model 48D Dante Bridge and a printed
copy of this guide. If the specific applica-
tion requires a source of 12 volts DC it
must be provided separately. A compatible
power supply, the Studio Technologies’
PS-DC-02, is available as an option.
If one or two Model 48D units are going
to be mounted in a 19-inch equipment rack
then an optional rack-mount installation kit
is required. Specific kits are available for
rack-mounting one or two Model 48D units.
If one or more rack-mount kits were pur-
chased they would typically have shipped
in separate cartons.
