4.2.3 CobraNet™ settings
The
CobraNet™
settings
page
is
shown
below
in
Figure 4-4.
One
of
the
key
features
of
the
MTS
ION
is
the
ability
to
set
up
to
4
CobraNet™
audio
transmitters
and
8
CobraNet™
receivers.
In
addition,
MTS
has
provided
the
ability
to
set
each
bundle
subchannel
configuration.
The
settings
are:‐
•
Transmitter setup: This section covers the CobraNet™ transmitters. The
CS496xxx
chipset
allows
for
up
to
4
transmitters,
each
of
up
to
8
channels,
subject
to
an
overall
channel
count
of
16
channels.
The
settings
are:‐
o
Bundle
number:
This
sets
the
bundle
address
of
each
transmitter.
The
bundle
numbers
are
0
(off,
ie
no
transmission),
1‐255
are
multicast,
256‐
65279
are
unicast
and
65280‐65535
are
private.
o
Priority:
This
sets
the
priority
of
the
transmitter.
If
bandwidth
resources
are
limited,
then
audio
will
be
transmitted
in
order
of
priority.
o
Unicast
mode:
If
the
transmitter
bundle
address
is
normally
unicast
(>255),
but
more
than
one
receiver
is
available
for
that
bundle
address,
then
the
bundle
can
be
transmitted
either
multicast
or
multi‐unicast.
o
Max
Unicast:
Depending
on
unicast
mode,
the
maximum
number
of
multi‐
unicast
bundles
can
be
set
between
1
and
4.
o
TX1…TX4: This lists the four transmitters associated with the bundle
address
and
allows
the
user
to
set
the
audio
subchannels
associated
with
that
bundle.
A
CobraNet™
CM2
type
interface
can
have
up
to
16
audio
channels,
numbered
1‐16.
The
subchannel
mapping
allows
the
user
to
decide
which
of
the
16
audio
channels
are
mapped
to
each
bundle
and
in
which
order
they
are
transmitted.
o
Resolution:
This
sets
the
word
length
of
the
transmitted
audio
to
16,
20,
or
24
bit.
Note:
if
the
word
depth
is
set
to
24bit,
then
only
7
audio
channels can fit in one bundle.
o
Transmitter
format
settings:
The
options
are
1.33mS,
2.66mS
or
5.33mS
latency.
Note:
there
are
significant
trade‐offs
if
changes
are
made
to
the
5.33mS
default
settings
(see
PM25).
Also
note
that
the
MTS
IONs
uses
all
16
CobraNet™
channels
of
the
CS496xxx
chipset,
so
only
a
sample
rate
of
48kHz
is
enabled
(96kHz
operation
is
not
possible).
