214’s power source. Alternately, an external
12 volt DC source can be 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 214’s power with no
interruption in operation.
Pushbutton Labeling
The two pushbutton switches used in
the Model 214 were selected for several
reasons. Foremost was the fact that they
are highly reliable, using gold-plated con-
tacts for long life in less-than-ideal environ-
ments. A second reason was that applying
customized labels to the pushbutton caps
would be very simple. The labels, text print-
ed on clear material, are placed under the
clear caps on the top of the pushbuttons.
From the factory the left pushbutton is
labeled COUGH and the right pushbutton
is labeled TALKBACK. These were selected
to be appropriate for many on-air applica-
tions 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 214 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
214’s enclosure. The enclosure does not
have to be disassembled to gain access.
