connected. For redundancy, both PoE and
the external source can be connected at
the same time. If both PoE and an external
12 volt DC source are connected, power
will be drawn only from the PoE supply.
If the PoE source becomes inoperative
the 12 volt DC source will provide the
Model 216’s power with no interruption
in operation.
Pushbutton Labeling
The four pushbutton switches used in
the Model 216 were selected for several
reasons. Foremost was the fact that they
are highly reliable, using gold-plated
contacts for long life in less-than-ideal
environments. A second reason was that
applying customized labels to the push-
button caps would be very simple. The
labels, text printed on clear material, are
placed under the clear caps on the top of
the pushbuttons.
From the factory the pushbuttons are
labeled, from left to right, COUGH,
TALKBACK 1, TALKBACK 2, and
TALKBACK 3. These were selected to be
appropriate for many on-air applications
in English-speaking locations. But it’s
expected that these may need to be
changed to meet the needs of specific
applications.
As a “head start” for some applications,
a clear sheet with a number of commonly
used pushbutton designations printed on
it is included in the shipping carton. These
were created at the factory using a stan-
dard personal computer graphics program
and laser printed onto sheets of transpar-
ency film. The desired pushbutton labels
can be cut out with a pair of scissors or an
X-ACTO® knife following the printed guide
lines that indicate the required size.
The clear lens on top of each pushbut-
ton cap can be removed with a fingernail
or small screwdriver. Be certain not to
scratch the pushbutton if a screwdriver or
other small tool is used. The clear label
can be removed and replaced. The cap
is then snapped back into the top of the
housing using finger-pressure only. No
tool is required to replace the cap.
If you need to make your own labels the
process is quite simple. Use a personal
computer to create the desired text. The
finished label size should be 0.625-inches
(15.8 mm) square. The completed artwork
can then be printed on transparency film
sheets using a laser or inkjet printer. These
sheets are readily available from most of-
fice supply stores. A pair of scissors or an
X-ACTO® (razor) knife will complete the
task.
Configuration
For the Model 216 to support the needs
of specific applications a number of op-
erating parameters must be configured.
These include headphone output gain
range, microphone preamplifier gain, P48
phantom power on/off status, pushbutton
operation, sidetone, headphone operating
mode, and system mode. Two pushbut-
ton switches and a 12-position DIP switch
assembly can be used to establish the de-
sired configuration. A 2-digit LED display
will indicate the selected headphone gain
range, gain of the microphone preamplifier
and the P48 phantom power on/off status.
The pushbutton switches, LED display,
and DIP switches are accessed through
an opening in the bottom of the Model
216’s enclosure. The enclosure does not
have to be disassembled to gain access.
