Figure 3-1: Block diagram showing the internal routing of the ION4.4/ION8.8
Both
ION4.4
and
ION8.8
have
simple
front
panel
adjustable
phantom
power
and
gain
on
the
mic/line
inputs.
The
rear
panel
serial
(RS485)
port
is
primarily
intended
for
Serial
Bridging
in
Cirrus
firmware
2.11.10
and
earlier
(Contact
Cirrus
logic
for
more
information).
There
are
2
network
ports
on
the
rear
panel
and
these
function
as
follows
(Note:
the
second
network
port
is
an
Ethernet
control
port
and
NOT
a
redundant
CobraNet™
port)…
•
CobraNet™
Port:
The
CobraNet™
port
uses
the
Cirrus
Logic
CS181xxx/CS496xxx
chipset
(similar
to
the
commonly
used
CM2
card).
This
allows
for
up
to
16
audio
input
channels
from
the
network,
up
to
16
audio
output
channels
to
the
network,
8
local
analog
mic/line
input
channels
and
8
local
analog
line
level
output
channels
from
the
network.
In
addition
to
audio
transport,
the
CobraNet™
port
provides
control
and
monitoring
capability
via
SNMP.
MTS
provides
an
OEM
version
of
Stardraw
control
with
embedded
MTS
SNMP
drivers
for
custom
GUI
rendering.
This
is
downloadable
from
the
MTS
website.
The
SNMP
controls
include
all
the
standard
CobraNet™
OID’s
and
the
Cirrus
DSP
extensions.

Logic’s
