MODEL 348
INTERCOM STATION
Ethernet Status LEDs
A total of four Ethernet status LEDs are locat-
ed below the two etherCON RJ45 connectors
on the Model 348’s back panel. A
LINK ACT
LED will light green whenever an active con-
nection to an Ethernet network has been es-
tablished. It will flash in response to Ethernet
data packet activity on that interface. A GbE
LED will light orange when a gigabit Ethernet
connection is present on that interface.
Dante Status LEDs
The SYS and SYNC LEDs, also located on
the back panel, display the operating status
of the Dante interface and its associated
network activity. After lighting red and green
as part of the power-up sequence the SYS
LED will light red to indicate that the Dante
interface is not ready. After a short interval it
will light green to indicate that it is ready to
pass data with another Dante device. The
SYNC LED will also be part of the power-up
sequence and will light red when the Model
348 is not synchronized with a Dante network.
It will light solid green when the Model 348 is
synchronized with a Dante network and an
external clock source (timing reference) is
being received. It will slowly flash green when
this specific Model 348 is part of a Dante net-
work and is serving as the clock master. It’s
possible that up to 30 or 40 seconds may be
required for the SYNC LED to reach its final
state.
How to Identify a Specific
Model 348
Functions within the Dante Controller and
STcontroller software applications allow spe-
cific Model 348 units to be identified. Each
application provides an “eyeball” icon that
when clicked will activate the Identify function.
When Identify is selected it will send a com-
mand to a specific Model 348 unit. On that
unit the red LEDs associated with the eight
Eight of the Dante audio output channels are
associated with the functioning of the eight
pushbutton switches. Two additional Dante
audio output channels are specified as moni
-
tor outputs. And the final Dante output chan-
nel provides a Hot Mic output function. Eight
of the Dante audio input channels are as-
signed to the monitor section. Each of these
inputs has an associated rotary encoder to
adjust its signal level. Eight more of the Dante
audio input channels serve as IFB program
inputs. These are used in conjunction with
the eight pushbutton switches when they are
configured for IFB operation.
Initial Operation
The Model 348 will start to function as soon
as a Power-over-Ethernet (PoE) or a 12 volts
DC power source is connected. However, it
may take up to 30 or 40 seconds for full op-
eration to commence. Upon initial power
up the various status LEDs, located on the
back panel, and the mic source, rotary en-
coder, and pushbutton LEDs on front panel
will light as the internal processors, Ethernet
network, and Dante connections begin to
function. The various LEDs will then become
operational, displaying the status of their as-
sociated functions.
Power Status LEDs
An LED labeled PoE is located below the pri-
mary Ethernet connector on the Model 348’s
back panel. It will light green if an Ethernet
signal that is providing PoE power is con-
nected. An LED labeled DC is located below
the 4-pin XLR connector that is provided for
connection to a DC power source. It will light
green if a source of 10 to 18 volts DC is con-
nected. If both the PoE and DC LEDs are
lit then the PoE Ethernet connection will be
providing power to operate the Model 348.
The DC power supply will be ready as a “hot
standby” should the PoE source fail.
