Upon Model 43D power up 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, DC status,
and audio level meter LEDs will light in a
sequence. Once the test sequence has
completed the two columns of level meter
LEDs associated with output 2 will momen-
tarily display the version number of the
unit’s application firmware (embedded soft-
ware). Details on how to “read” the version
number is provided in the Technical Notes
section of this guide.
The Model 43D will now begin normal op-
eration. The way in which the back panel
LINK/ACT, SYS, SYNC, and PoE LEDs light
will depend on the characteristics of the
connected Ethernet signal and the configu-
ration of the unit’s Dante interface. Details
will be covered in the next paragraph. The
user is presented on the front panel with
two input power status LEDs, two DC output
status LEDs, and four 5-segment LED audio
level meters. These resources are simple
to understand and should prove to be use-
ful as will be highlighted in the following
paragraphs.
Ethernet, PoE, and Dante
Status LEDs
Four status LEDs are located below the
etherCON connector on the Model 43D’s
back panel. The LINK/ACT LED will light
green whenever an active data 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 43D. The
SYS and SYNC LEDs display the operating
status of the Dante interface and associ-
ated Audio-over-Ethernet network. The SYS
LED will light red upon Model 43D 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 audio data
with another Dante device. The SYNC LED
will light red when the Model 43D is not
synchronized with a Dante network. It will
light solid green when the Model 43D is fully
synchronized with a Dante network and an
external clock source (timing reference) is
being received. It will slowly light on and off
green if this specific Model 43D is serving
as the clock master for the Dante network.
How to Identify a Specific
Model 43D
The Dante Controller software application
offers an identify command that can be
used to help locate a specific Model 43D.
When identify is selected for a specific unit
its meter LEDs will light in a unique pattern.
In addition, the SYS and SYNC LEDs, locat-
ed directly below the etherCON connector
on the back panel, will slowly flash green.
After a few seconds the LED identification
patterns will cease and normal Model 43D
level meter and Dante status LED operation
will again take place. Audio performance
will not be impacted by the use of the iden-
tify command. As such it’s perfectly accept-
able to use the identify command any time
it would be useful.
Level Meters
The Model 43D contains four 5-segment
LED level meters, two associated with each
IFB output. The meters are provided as a
support aid during installation, configura-
tion, operation, and troubleshooting. The
