compatible with standard RJ45 plugs,
etherCON allows a ruggedized and lock-
ing interconnection for harsh or high-reli-
ability environments. The Model 216’s
operating power can be provided by way
of the Ethernet interface using the Power-
over-Ethernet (PoE) standard. This allows
fast and efficient interconnection with the
associated data network. To support PoE
power management, the Model 216’s PoE
interface reports to the power sourcing
equipment (PSE) that it’s a class 2 (low
power) device. The unit can also be pow-
ered using an external source of 12 volts
DC. For redundancy, both power sources
can be connected simultaneously. If both
sources are connected PoE will power the
unit. Four LEDs display the status of the
network connection, PoE power source,
and Dante interface.
Configuration and Flexibility
Model 216 configurations are made using
twelve DIP switches and two pushbutton
switches. The 12-position switch array
configures parameters such as the push-
button operating modes, sidetone func-
tion, headphone control assignment, and
the system mode. The pushbuttons are
used to set the gain of the microphone
preamplifier and control the on/off status
of the microphone phantom power func-
tion. The switches and pushbuttons are
accessible via the bottom of the Model
216’s enclosure; the unit does not have to
be disassembled. Changes made to any
of the configuration parameters become
active immediately. To prevent unwanted
access to the configuration switches and
pushbuttons a security panel, included
with each unit, is attached to the bottom
of the enclosure.
In the world of broadcast and production
audio it’s fair to say that applications vary
widely. To this end, one or two additional
XLR connectors can easily be mounted
into the Model 216’s back panel. Multiple
3-position “headers” located on the Model
216’s circuit board provide technician
access to many of the input and output
connections. Using a variety of optional
factory-supplied modules and interface
cable kits allows a Model 216 to be opti-
mized to meet the needs of specific ap-
plications. For example, some applications
may prefer to use a multi-pin XLR connec-
tor to interface with a headset. This can
easily be accomplished by installing the
appropriate 6- or 7-pin XLR connector kit
and making a few simple connections.
Other applications may benefit from hav-
ing “mult” or “loop-through” connections,
something easily incorporated into a Model
216. And access to the relay contacts can
be made adding a 4-pin XLR connector kit.
Two general-purpose relay contacts are
provided on the Model 216’s circuit board.
Accessible using 3-pin “header” connec-
tors they allow specialized configurations
to be created. Under software control, the
form-A (normally open) solid-state relay
contacts follow the state of the main and
talkback 1 pushbuttons. Taking advantage
of the two locations provided for additional
XLR connectors, a technician may easily
implement a variety of functions such as
a tally indication or audio muting during
talkback.
Future Capabilities &
Firmware Updating
The Model 216 was designed so that its
capabilities can be enhanced in the future.
The primary additions will be in the area of
Dante remote control functionality. Once an
