The
following
table
provides
the
settings
possible
for
choices
Live
Clock
Priority
and
provides
some
information
on
each
of
these
settings:
0
(always
slave)
“STL”
Unit
will
never
be
master
and
is
only
used
with
Ethernet
radios.
0
(always
slave)
This
unit
will
never
be
used
as
clock
master.
3
(default)
The
usual
and
default
setting
for
an
8x8
node.
4
(Secondary
Master)
Nodes
with
this
setting
will
be
used
as
clock
masters
before
those
set
to
3.
5
(Primary
Master)
Nodes
set
to
this
setting
will
be
used
as
clock
masters
before
those
set
to
4.
7
(Always
Master)
This
forces
a
particular
node
to
be
clock
master,
even
if
another
node
is
currently
clock
master.
If
this
mode
becomes
available
then
the
usual
prioritization
is
used.
7
(Always
Master)
“STL
Snake”
This
setting
forces
a
particular
node
to
be
clock
master.
Use
only
when
two
nodes
are
connected
back
to
back
without
an
Ethernet
Switch.
w
IMPORTANT!
Only
a
single
node
on
a
Livewire
network
should
ever
be
set
to
7
(Always
Master).
For
this
reason
we
do
not
recommend
using
that
selection.

Receive
Buffer
Size
This
setting
determines
the
amount
of
buffering
in
the
receiver.
Buffering
is
needed
to
compensate
for
jitter
in
network
packet
delivery.
Usually
the
biggest
source
of
jitter
is
a
PC
using
the
IP
driver.
Real
‐
time
performance
varies
a
lot
from
one
system
to
another;
some
computers
can
provide
very
low
timing
irregularities
and
allow
the
receive
buffer
to
be
reduced
to
achieve
lower
audio
delay.
The
default
setting
is
100
ms.
