connection
between
two
STAGE8.8’s
(ie
no
Ethernet
switch),
 use
the
two
Data

connections
to
separate
the
DC
supplies.
For
a
typical
stage
box,
the
 two
injectors
would
be
at
the
control
room/mixing
console
and
just
the
long
cable
with
 Data
and
power
to
the
stage.
See

 The
Cobranet
network
port
also
carries
the
24
volt
power
on
the
unused
4
wires
of
the
 100BaseTx
connection.
The
STAGE8.8
ships
with
a
24volt
PSU
and
PoE
injector
(note
 the
Stage8.8
is
a
custom
PoE
and
not
IEEE802.3af).

Configuration
(No
DSP)
 
 The
STAGE8.8
ships
with
the
8
analog
inputs
linked
to
CobraNet®
Transmitter
sub
 channels
1‐8
and
CobraNet®
Receiver
sub
channels
33‐40
are
linked
to
the
8
analog
 outputs.
This
allows
the
STAGE8.8
to
be
used
‘out
of
the
box’
by
merely
setting
up
 Transmitter
and
Receiver
(‘Bundle’)
network
addresses.
 
 However,
the
STAGE8.8
has
the
capability
of
transmitting
16
CobraNet®
channels
and
 receiving
16
CobraNet®
channels,
so
a
more
sophisticated
routing
can
be
configured
 using
the
free
utility
Cobranet
Discovery
(CNDISCO)
from
Cirrus
Logic.
 4.1 CNDISCO
‐
Setup
 
 To
use
CNDISCO,
the
host
PC
or
laptop
must
be
set
to
the
default
IP
subnet
in
order
to
 talk
to
the
STAGE8.8.
Figure 4-1
below
shows
the
method
of
setting
up
a
Windows
 computer.
NOTE:
The
default
IP
address
of
the
STAGE8.8
IS
192.168.192.50.
 
 
 Figure 4-1: Setting
up
the
IP
address
and
subnet
mask.
 • Go
to
Control
Panel
and
then
open
“Network
connections”.
 • Click
on
the
General
tab
and
open
“Properties”.
 • Select
“Internet
Protocol
(TCP/IP)”
and
click
on
properties.
 Page

...

  • Page 13: Advanced Settings

    • Finally,
change
the
selection
from
“Obtain
an
IP
address
automatically”
to
“Use
 the
following
IP
address”
and
set
to
your
desired
IP
domain,
eg:‐
 • IP
address:
192.168.192.50
 • Subnet
mask:
255.255.255.0
 • After
finishing
using
the
CNDISCO
application,
return
to
the
Control
Panel
and
 reset
the
selection
back
to
“Obtain
an
IP
address
automatically”.
 
 If
an
intelligent
or
managed
switch/router
is
in
use,
then
the
switch
address
will
need
to
 be
set
to
the
same
subnet,
usually
192.168.1.1
or
192.168.1.254
are
the
most
common
 default
addresses.
 4.2 Advanced
settings
 
 In
order
to
use
CNDISCO
effectively,
it
will
be
necessary
to
enable
the
configuration
and
 advanced
features.
This
will
also
allows
you
to
put
any
version
of
firmware
on
any
 hardware‐compatible
CobraNet™
module.
CNDISCO
needs
to
have
the
particular
 firmware
version
of
a
device
in
its
firmware
directory
in
order
to
properly
identify
the
 device
for
compatible
firmware
upgrades.
Should
the
situation
arise
where
you
know
 the
device
is
a
specific
model
but
CNDISCO
says
there
are
no
compatible
firmware
 upgrades,
using
the
advanced
feature,
you'll
be
able
to
update
the
firmware
anyway.

 
 How
to
enable
the
advanced
feature:
 
 Open
cndisco.ini
(WinXP)
or
the
config
file
(WinVista/Win7)
the
in
Notepad
 
 Its
usually
in
a
directory
like
this:
C:\Program
Files\Peak
Audio\CobraNet™
Discovery.

 
 Find
the
Configuration
section.
It
usually
looks
something
like
this:
 
 [Configuration]
 Adapter
Index=[10]
[10]
Broadcom
NetXtreme
57xx
Gigabit
Controller
 Firmware
Location=C:\Program
Files\Peak
Audio\CobraNet™
Discovery\firmware
 
 Start
a
new
line
after
one
of
the
lines
in
that
section
and
type
in
Advanced
Feature=1.
 Add
CC_Enable=1
under
Advanced
Feature=1
 
 It
should
look
something
like
this
when
you're
done:
...

  • Page 14: Configuration

    
 <add
key
"Advanced
Feature"
value="1"
/>
 
 Save
the
changed
.ini/config
file
and
exit
Notepad.
The
advanced
features
are
now
 enabled.
 
 Now
when
you
update
the
firmware
you'll
see
a
check
box
in
the
"Select
Firmware
 Version"
dialog
box
marked
"Show
All
Firmware
Versions".
Check
the
box
and
you'll
be
 able
to
choose
from
all
the
firmware
versions
stored
in
the
firmware
directory.
 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

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

settings:
This
section
covers
the 
more
advanced
variables
not
 usually
associated
with
bundle
management
and
which
apply
to
the
CobraNet™
 device
globally
(see
 Figure 4-4 ).
These
are
explained
in
detail
in
the
CNDISCO
 
 manual,
but
2
are
of
particular
importance
to
the
ION
series
interfaces,
ie… Persistance:
The
STAGE8.8
is
a
very
simple
interface
product
and
does
not
 have
a
preset
memory,
so
“persistence”
is
used
to
store
the
last
settings
in
 
 case
of
power
down.
Please
note… ll
CobraNet™
settings
need
up
to
1
minute
to
establish
  persistence,
as
they
are
stored
in
the
CobraNet™
flash.
If
the
ION
 power
is
cycled
before
the
settings
are
stored
to
flash,
then
the
 settings
will
be
lost.

  If
the
persistence
tick
box
is
off,
then
no
settings
will
be
saved.
 o Mode
Rate
Control:
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),
particularly
in
terms
of
the
number
of
switch
 hops
that
can
be
used.

    5 Firmware
 The
Cobranet
firmware
is
updated
using
the
free
utility
(Cobranet
Discovery)
from
 Cirrus
Logic
–
see
Figure 5-1
below.
 Figure 5-1: Cobranet Discovery showing 2.11.9 firmware After
loading
the
CNDISCO
application,
Advanced
features
will
need
to
be
enabled.
 Enabling
advanced
features
in
CNDISCO
allows
you
to
put
any
version
of
firmware
on
 any
hardware‐compatible
Cobranet
module
you
wish.
CNDISCO
needs
to
have
the
 particular
firmware
version
of
a
device
in
its
firmware
directory
in
order
to
properly
 identify
the
device
for
compatible
firmware
upgrades.
Should
the
situation
arise
where
 you
know
the
device
is
a
specific
model
but
CNDISCO
says
there
are
no
compatible
 firmware
upgrades,
using
the
advanced
feature,
you'll
be
able
to
update
the
firmware
 anyway.

 
 How
to
enable
the
advanced
feature:
Firstly,
open
cndisco.ini
in
Notepad.

Its
usually
in
 a
directory
like
this:
C:\Program
Files\Peak
Audio\CobraNet
Discovery.
Then
find
the
 Configuration
section.
It
usually
looks
something
like
this:
 
 [Configuration]
 Adapter
Index=[10]
[10]
Broadcom
NetXtreme
57xx
Gigabit
Controller
 Firmware
Location=C:\Program
Files\Peak
Audio\CobraNet
Discovery\firmware
 
 Start
a
new
line
after
one
of
the
lines
in
that
section
and
type
in
Advanced
Feature=1.
It
 should
look
something
like
this
when
you're
done:
 
 [Configuration]
 Adapter
Index=[10]
[10]
Broadcom
NetXtreme
57xx
Gigabit
Controller
 Firmware
Location=C:\Program
Files\Peak
Audio\CobraNet
Discovery\firmware
 Advanced
Feature=1
 
 Save
the
file
and
exit
Notepad.
The
advanced
feature
is
now
enabled.
 
 Now
save
the
MTS
cobranet
binary
file
“MTS_2_11_xx.bin”
to
the
Firmware
folder
and
 use
CNDISCO
to
upload
the
firmware.
Please
ensure
that
you
ONLY
use
the
MTS
binary,

update
the
firmware
you'll

dialog
box
marked
"Show

Firmware
Versions".
Check
the
box
and
you'll

all
the

all
“Unconditionally”
and
select
the
“MTS_2_11_xx.bin”…
