HDMI Daisy-Chained, Duplex, with RS232 serial
This
configuration
example
shows
a
daisy
‐
chained
DUPLEX
mode
extension
application
for
HDMI
video.
If
the
source
content
is
protected
(with
HDCP),
then
it
will
remain
protected
to
the
local
port,
and
all
the
way
to
each
receiver’s
output.
Note
that
the
“HDCP
‐
key
‐
limit”
may
apply
in
this
case.
See
the
Application
Notes
section.
If
the
source
provides
embedded
HDMI
‐
audio,
that
will
be
passed
to
each
remote
HDMI
display
unmodified.
The
digital
audio
can
also
be
driven
out
the
analog
audio
jacks
as
a
configurable
option
(see
MAGui).
There
is
also
full
‐
duplex
serial
‐
control
of
all
displays.
Since
a
duplex
(twin)
fiber
is
being
used
between
the
TX
and
RX
units,
the
displays
CAN
send
responses
back
to
the
control
system.
If
a
simplex
(single)
fiber
were
used,
then
only
video
and
serial
can
flow
TO
the
display,
and
no
responses
can
be
returned
to
the
control
system.
If
the
displays
are
serial
‐
port
addressable,
then
the
default
serial
mode
(broadcast
to
all
receivers)
can
be
utilized.
All
return
data
will
be
merged
together
–
so
it’s
important
that
only
one
display
respond
at
a
time.
If
the
displays
are
not
addressable,
then
it’s
possible
to
make
distinct
“virtual
connections”
with
individual
receivers’
serial
ports.
