Using Dante Controller these names can
be revised as appropriate for the specific
application.
The Model 216 will support audio sample
rates of 44.1 kHz or 48 kHz with the ability
to select pull-up/pull-down values. These
parameters can be selected using the
Dante Controller application but in most
applications 48 kHz will be appropriate.
The Model 216 can serve as the clock
master for a Dante network but in most
cases that would not be optimal.
Operation
At this point the audio, Ethernet, and
power connections should have been
made. The pushbutton labels may have
been revised. The desired configuration
should have be made using the pushbut-
ton and DIP switches. The Dante receiver
(input) and transmitter (output) channels
should have been routed using the Dante
Controller software application. Normal
operation of the Model 216 can now
begin.
Initial Operation
The Model 216 will begin functioning a
few seconds after its power source is
connected. 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 subsequently no longer be available
uninterrupted operation will continue using
the external source.
Upon Model 216 power up most of the
status and backlight LEDs along with the
2-digit display will activate in a test se-
quence. The PoE, USB, and SIG/PEAK
LEDs, located on the back panel, will light
one after another. On the top surface of
the Model 216 the two status LEDs and
the backlight LED associated with the main
pushbutton switch and the status LED and
the backlight LEDs associated with the talk-
back pushbutton switches will momentarily
light in sequence. Once that sequence has
completed all the LEDs will begin to func-
tion normally.
The 2-digit LED display is visible on the
bottom of the unit when the security panel
is removed. Upon unit power up, all seg-
ments of each display digit will light briefly
as a confirmation that they are function-
ing. The version number of the operating
firmware (embedded software) will briefly
display. For example, the first firmware
version that shipped with the Model 216
displayed 1.0. Next, the setting of the
headphone output level will be displayed
for three seconds, displaying either Lo or
Hi. During this interval the level setting can
be changed by pressing one of the buttons
that are located to the right of the display:
press the up button for high and the down
button for low. After a few seconds the dig-
its will briefly turn off and the gain of the mi-
crophone preamplifier (in dB) and the P48
phantom power on/off status will display
and remain active. Unless either or both
of the pushbutton switches are pressed,
approximately 10 seconds after the unit
begins operation the display will stop light-
ing. This is a power-saving measure. The
display will again light after either or both of
the pushbuttons are pressed.
Note that the way in which the LINK/ACT,
SYS, and SYNC LEDs (all located below
the etherCON connector) will light depends
on characteristics related to the connected
Ethernet signal and the configuration of the
