Model 5202
Dante to Phones and Line Output Interface
Initial Operation
The Model 5202 will immediately begin to
function after a Power-over-Ethernet (PoE)
power source is connected. However, full
operation may take up to 20 seconds to
begin. Upon initial power up the four status
LEDs located 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 complete 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 com-
pleted and the Dante connection has been
established audio signals can be available.
Ethernet, PoE, and Dante
Status LEDs
Four status LEDs are located below the
Ethernet connector on the Model 5202’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 5202. 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 5202 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 5202 is
not synchronized with a Dante network. It
will light solid green when the Model 5202
is synchronized with a Dante network and
an external clock source (timing reference)
is being received. It will slowly flash green
when the Model 5202 is part of a Dante
network and is serving as a clock master.
How to Identify a Specific
Model 5202
The Dante Controller software application
offers an identify command that can be
used to help locate a specific Model 5202.
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 lev-
el of the two Dante audio receiver (input)
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 nominal (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 lights
red in color when a signal level is –5 dBFS
or greater, indicating that a potentially
“clipped” (distorted due to excessive level)
signal is present.
Headphone Output
Dante input channel 1 is routed to the left
headphone output channel. This signal is
connected to the tip connection on both
the 3.5 mm and ¼-inch headphone output
