Up to

Ho

maximum
number
of components that can be daisy-chained in a single route
is
17 (i.e.,
a
maximum
of
16 i.LINK

route is called a
“hop.

Notes
•
Some i.LINK
components
(such
as
personal
computers)
do not
transfer
signals
when

to
the
operation manual
of
each
component
to
be

befor
e
you hook
them
up.

The maximum
transmission
rate
of
an
i.LINK
component
is
printed near
its
i.LINK
connector
.
The
indications
S100,
S200,
and
S400
refer
to
maximum
transmission
rates
of
100, 200, or
400 Mbps*,
respecti
v
ely
. The
actual
transmission
rate
may
be
faster or
slo
wer
,
depending
on
the
dif
fer
ences
in
transmission
rates and
specif
ications
among
the
connected
components.
z
W
hat is Mbps?
“Mbps
” is
an
abbr
eviation
for
me
gabits
per
second.
It
indicates
the amount
of
data
transmitted
per
second.
F
or
example,
a
rate
of 200
Mbps
means
200
me
gabits
of data
ar
e
transmitted
in
one
second.
LINC (Logical
INterface Connection)
Befor
e an
audio
signal
can
be
transmitted
between
i.LINK
components, a
“LINC
” must
first
be
established
between
the r
ecei
ving
component
(of
the audio
signal)
and
the
sending component.
Establishing
a
“LINC
” means
establishing a
logical
path
for
the
transmission
of
digital
audio signals
between
the
tw
o
components.
Each
logical
path
has
an
ID
number
. Since
the
component
that
sends
an audio
signal
must
output
the
signal
to
a
path,
and
the
component that r
ecei
v
es the signal must input it fr
om the
same
path, the
path must be
mutually
kno
wn
by
both
components. During the establishment of a LINC, the follo
wing communication occurs between the tw
o i.LINK
components. Example A component

a LINC

a CD
player

signal

The component that will r

CD
player
sends
a
request
and
path
information
to the
CD player
to establish
a
transmission path for the audio signal.

becomes
possible
only after the
communication
described

has
occurr
ed and
a
LINC
has
been
established.

i.LINK functions
i.LINK is
a
serial
digital
interf
ace
that
supports
the
bidir
ectional transmission
of
audio
and
video
signals,
commands, and
ev
en
component
status
information.
All
that is needed to hook up i.LINK components ar
e i.LINK
connecting cables.
Audio
and
video
components
connected within
an
i.LINK
conf
iguration
can
be
used
to
perform a
wide
range
of
operations
and
data
exchanges
that is sure to e
xpand as the number and v
ariety of i.LINK
components gr

Since i.LINK
allo
ws
data

transmitted
fr

one
component to other components to which it is not dir
ectly
connected,
ther
e
is
no
need
to pay
attention
to connection
or
