Model 5204
Dual Line Input to Dante Interface
signal source connections to line input A
and line input B should have been made
as desired. A device may have been con-
nected to the USB dedicated charging
port. Normal operation of the Model 5204
can now begin.
Initial Operation
The Model 5204 will immediately begin to
function as soon as a Power-over-Ethernet
(PoE) power source is connected. At this
time the USB dedicated charging port will
become functional. However, full operation
may take up to 20 seconds to begin. Upon
initial power up the four status LEDs locat-
ed on the back panel will begin to light. The
meter LEDs on the front panel will light in a
test sequence. After the meter LEDs com-
plete their test sequence one meter LED
associated with channel 1 and one meter
LED associated with channel 2 will briefly
light to indicate the version number of the
unit’s firmware (embedded software). Once
that sequence has completed and the
Dante connection has been established
full operation will begin.
Ethernet, PoE, and Dante
Status LEDs
Four status LEDs are located below the
Ethernet connector on the Model 5204’s
back panel. The PoE LED will light green
to indicate that Power-over-Ethernet (PoE)
associated with the connected Ethernet
signal is providing operating power for the
Model 5204. The LINK/ACT LED will light
green whenever an active connection to
a 100 Mb/s Ethernet network has been
established. It will flash in response to data
packet activity. The SYS and SYNC LEDs
display the operating status of the Dante
interface and associated network. The
SYS LED will light red upon Model 5204
power up to indicate that the Dante inter-
face 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
5204 is not synchronized with a Dante
network. It will light solid green when the
Model 5204 is synchronized with a Dante
network and an external clock source
(timing reference) is being received. It will
slowly flash green when the Model 5204 is
part of a Dante network and is serving as
a clock master.
How to Identify a Specific
Model 5204
The Dante Controller software application
offers an identify command that can be
used to help locate a specific Model 5204.
When identify is selected for a specific unit
the SYS and SYNC LEDs on that unit will
slowly flash green.
Level Meters
Two 7-step LED meters will display the
level of the two Dante transmitter (output)
channels. The meter steps are calibrated
in dBFS which indicates the number of dB
below the maximum possible digital signal
level. The maximum level is 0 dBFS which
occurs when the digital audio data is all
“1”s. In typical applications a signal level
of –20 dBFS would be the desired nomi-
nal (normal average) value. The five meter
steps that have a threshold of –20 dBFS
and less light with the color green. The
step that lights at –15 dBFS and greater
is yellow in color and indicates a “hot” or
above average signal level. The top step
