4.3 Configuration
The
CNDISCO
manual
(found
in
the
C:\Program
Files\Cirrus
Logic\CobraNet™
Discovery
folder)
will
explain
in
detail
most
of
the
configuration
processes,
so
these
have
not
been
repeated
here.
However,
there
are
some
useful
features
of
the
CobraNet™
protocol
that
are
not
covered
explicitly,
ie…
One
of
the
key
features
of
the
STAGE8.8
product
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 (see Figure
4-2
). The CS496112 chipset allows for up to 4 transmitters, each of up to 8
channels,
subject
to
an
overall
channel
count
of
2
analog
input
channels
and
8
network
audio
streaming
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 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 Transmitter1…Transmiter4: This lists the four transmitters associated
with
the
bundle
address
and
allows
the
user
to
set
the
audio
subchannels
associated
with
that
bundle.
The
subchannel
mapping
allows
the
user
to
decide
which
of
the
8
audio
channels
are
mapped
to
each
bundle
and
in
which
order
they
are
transmitted.
o Subformat 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
UnicastMode:
This
value
can
be
used
to
override
or
modify
the
normal
unicast
vs.
multicast
implications
of
the
assigned
bundle
number.
The
normal
default
value
is
‘Never
Multicast’.
The
available
options
are:
Always
Multicast
–
All
bundles
are
sent
multicast
regardless
of
Bundle
number.
