Operation
At this point the Model 45DC should have
its party-line and Ethernet connections
made. Depending on the application an
external 12 volt DC power connection may
have also been made. The Dante receiver
(input) and transmitter (output) channels
should have been routed using the Dante
Controller software application. Normal op-
eration of the Model 45DC can now begin.
Initial Operation
The Model 45DC will begin functioning a
few seconds after its power source is con-
nected. As previously discussed, the power
source can be provided by Power-over-
Ethernet (PoE) or an external source of
12 volts DC. If both are connected the PoE
source will power the unit. Should PoE sub-
sequently no longer be available, operation
will continue using the external source.
Upon Model 45DC power up many of
the status and meter LEDs will activate in
test sequences. The PoE and USB LEDs,
located on the back panel, will light one
after another. On the front panel the input
power, channel status and level meters
LEDs will light in a sequence. Once the test
sequences have completed two columns
of front-panel level meter LEDs will mo-
mentarily display the version number of the
unit’s application firmware. Details on how
to “read” the version number is provided in
the Technical Notes section of this guide.
The Model 45DC will now begin normal
operation. The way in which the LINK/ACT,
SYS, SYNC, and PoE LEDs (all located on
the back panel below the etherCON con-
nector) light will depend on characteristics
related to the connected Ethernet signal
and the configuration of the unit’s Dante
interface. Details will be covered in the next
paragraph. The user is presented on the
front panel with two pushbutton switch, two
input power status LEDs, six channel status
LEDs, and four 5-segment LED level me-
ters. These resources are simple to operate
and understand, as will be described in
later paragraphs.
Ethernet, PoE, and Dante
Status LEDs
Four status LEDs are located below the
etherCON connector on the Model 45DC’s
back panel. The LINK/ACT LED will light
green whenever an active connection to
a 100 Mb/s Ethernet network has been
established. It will flash on and off in re-
sponse to data packet activity. The PoE
LED will light green whenever Power-
over-Ethernet (PoE) associated with the
connected Ethernet signal is providing
operating power for the Model 45DC. The
SYS and SYNC LEDs display the operating
status of the Dante interface and associ-
ated network. The SYS LED will light red
upon Model 45DC power up 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 light red
when the Model 45DC is not synchronized
with a Dante network. It will light solid
green when the Model 45DC is synchro-
nized with a Dante network and an external
clock source (timing reference) is being re-
ceived. It will slowly light on and off green
when the Model 45DC is part of a Dante
network and is serving as a clock master.
