Ethernet, PoE, and Dante
Status LEDs
Four status LEDs are located below the
Ethernet connector on the Model 216’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
response to data packet activity. The PoE
LED will light green whenever Power-
over-Ethernet (PoE) associated with the
connected Ethernet signal is providing op-
erating power for the Model 216. The SYS
and SYNC LEDs display the operating sta-
tus of the Dante interface and associated
network. The SYS LED will light red upon
Model 216 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 216 is not synchronized with
a Dante network. It will light solid green
when the Model 216 is synchronized 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 216 is part of a Dante
network and is serving as a clock master.
How to Identify a Specific
Model 216
The Dante Controller software application
offers an identify command that can be
used to help locate a specific Model 216.
When identify is selected for a specific
unit the SYS and SYNC LEDs on that unit
will together light slowly on and off. This
makes it a very simple task to observe the
selected Model 216 unit.
Signal Present/Peak LED
A dual-color LED is located on the Model
216’s back panel, directly below the mi-
crophone input connector. It monitors the
output of the microphone preamplifier,
providing a 3-step signal level indication.
The LED will light green when the signal
level is –40 dBFS or greater, both green
and red at the same time when the signal
level is –14 dBFS or greater, and red when
the signal level is –4 dBFS or greater. Dur-
ing normal operation the LED should light
green and, with peak signals, occasion-
ally both green and red at the same time.
If the LED is lit constantly green and red at
the same time the gain of the microphone
preamplifier most likely should be reduced.
The LED should never light red only as this
would indicate a signal that’s in danger of
reaching 0 dBFS (digital “clipping”). This
would indicate that the gain of the micro-
phone preamplifier should be significantly
reduced.
Pushbutton Switches and
Status LEDs
Four pushbutton switches are used to
control the audio signals on the main and
talkback output channels. The way each
operates depends on the selected con-
figuration. Five LED indicators are located
adjacent to the pushbuttons and reflect
the status of the audio signals associated
with the main and talkback output chan-
nels. The pushbuttons’ clear lenses are
backlit using white LEDs. The intensity
(brightness) of the LEDs is configured from
a choice of two values, low or high. The
backlighting does not provide an indication
of the associated pushbutton’s status nor
do they serve as a tally function, but rather
allow the pushbutton’s labeling and loca-
tion to be visible in low-light conditions.
