When the system mode is set for produc-
tion, the main output channel is never
muted in response to the talkback output
channel being active. In this way the main
and talkback output channels can be used
independently, with neither impacting the
other. An example of where this would be
useful is allowing the Model 212 to provide
two independent talkback functions; the
main and talkback buttons can be used
independently or simultaneously. The pro-
duction mode can prove very useful when
selected for the correct application, but it’s
not appropriate for on-air use!
Conclusion
Once the multitude of DIP switches have
been set to their desired configuration,
the security plate should be reattached.
The four rubber bumpers should be hand-
tightened only. No tools should be used.
Operation
At this point the desired input, output,
and power connections should have been
made. The button labels may have been
revised. Finally, the configuration switches
should have been set. Normal operation of
the Model 212 can now begin. The unit will
begin functioning as soon as the source of
nominal 24 volts DC is connected.
Upon Model 212 power up, the three
status LEDs will light in succession as a
firmware “boot up” indication. The unit will
then begin normal operation. Depending
on the selected configuration, one LED
associated with the status of the main out-
put may be lit. The user is now presented
with two buttons, three LEDs, and two
rotary controls. These are simple to oper-
ate and understand, as will be described
in the following paragraphs.
Pushbutton Switches and
Status LEDs
Two pushbutton switches are used to
control the main and talkback output
channels. The way each operates de-
pends on the selected configuration.
Three LED indicators are located adjacent
to the buttons. They reflect the status of
the main and talkback output functions.
Main Output Button and LED Indicators
The button on the left, factory labeled
as COUGH, functions according to the se-
lected configuration. Two LED indicators,
located directly above the button, are as-
sociated with the status of the main output
channel. The green LED, located on the
right, is lit whenever the main output chan-
nel is active. This could be considered as
an “on-air” or mic active indicator. At the
least it should serve as a “careful what you
say” warning! If the Model 212’s system
mode is configured to on-air, the red LED,
located on the left, will be lit when the
main output channel is muted. This indi-
cates that it’s safe to speak as one sees fit.
If the Model 212’s system mode is config-
ured to production, the red LED will never
light. This is to reflect the fact that the main
output button has now taken on a function
similar to that of the talkback output but-
ton. To clarify, when the Model 212 is set
to the production mode, the red LED will
never light; the green LED will light when-
ever the main output channel is active.
Main Output Button Modes
• Push to mute: If this mode is selected
the main output channel is normally
active. The main output channel will
mute whenever the button is pressed
and held.
