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 215’s power with no
interruption in operation.
Pushbutton Labeling
The three pushbutton switches used in
the Model 215 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, the middle pushbutton is
labeled TALKBACK 1, and the right push-
button is labeled TALKBACK 2. 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 pushbutton
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 re-
quired 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 215 to support the needs of
specific applications a number of operat-
ing parameters must be configured. These
include headphone output gain range, mi-
crophone preamplifier gain, P48 phantom
power on/off status, pushbutton operation,
sidetone, headphone operating mode, and
system mode. Two pushbutton switches
and a 12-position DIP switch assembly can
be used to establish the desired configura-
tion. 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 push-
button switches, LED display, and DIP
switches are accessed through an opening
in the bottom of the Model 215’s enclosure.
The enclosure does not have to be disas-
sembled to gain access.
To prevent unauthorized personnel from
changing the configuration settings, a se-
curity panel is attached to the bottom of the
Model 215’s enclosure. For convenience,
