How
to
Use
ASI-Receive
Mode
The
Adtec
EN-Series
with
optional
integrated
modulator
has
been
designed
with
different
applications
in
mind.
The
encoder
/
modulator
combo
supports
three
different
modes
of
operation.
1)
They
can
be
used
together.
2)
The
modulator
only
can
be
used
as
a
stand
alone
device
3)
The
encoder
only
can
be
used
as
a
stand
alone
device.
The
default
mode
of
operation
has
the
‘ASI
Receive
Mode’
configuration
turned
OFF.
In
this
mode,
the
SDI
input
serves
as
the
primary
SD/HD-SDI
video
input
into
the
encoder.
The
encoder
processes
the
video/audio/ancillary
data
and
places
the
compressed
data
into
a
transport
stream.
The
transport
stream
is
fed
concurrently
to
the
ASI
output
module,
IP
output
module,
and
internal
modulator
input.
The
ASI
output
will
always
be
enabled,
while
IP
and
RF
outputs
have
individual
controls.
The
second
mode
of
operation
has
the
‘ASI
Receive
Mode’
configuration
turned
ON.
In
this
mode,
the
SDI
input
is
changed
to
an
ASI
input.
This
can
be
useful
in
situations
where
the
encoder
may
not
meet
specific
requirements
for
a
job
without
losing
up
to
32APSK
optional
modulation
capabilities.
The
ASI
input
is
routed
directly
to
the
ASI
output
module
and
to
the
internal
modulator
input.
All
internal
paths
to
and
from
the
encoder
module
are
terminated
in
this
mode
with
encode
functionality
disabled.
The
modulator
will
be
acting
as
a
stand
alone
device
with
3
ASI
outputs
available
for
pre-modulation
monitoring
capability.
In
this
mode,
the
modulator
interface
rate
must
also
match
the
ASI
rate
coming
into
the
encoder
for
proper
RF
modulation.
There
is
no
reporting
of
the
ASI
input
data
rate
or
rate
adaptation
supported
at
this
time.
There
is
no
null
packet
insertion
or
null
packet
dropping
support
at
this
time.
The
ASI
input
rate
must
be
configured
/
viewed
from
the
device
feeding
the
EN
unit.
The
third
mode
can
be
used
by
DISABLING
modulator
transmit.
To
enable
your
Adtec
EN-series
device
for
ASI
Receive
Mode,
follow
the
following
steps:
Step Action
1
On
the
rear
panel
of
the
device,
connect
your
ASI
cable
to
the
"ASI-IN"
BNC
connector.
This
is
a
shared
connector;
it
also
functions
as
the
SDI-In
connector.
2
Access
the
Web
UI
for
your
unit.
3
On
the
"Video"
tab,
select
<On>
as
the
option
for
"ASI
Receive
Mode".
This
routes
the
ASI
signal
to
the
unit's
internal
modulator.
4
On
the
Status
Display
on
the
LCD
Panel
(unit
front
panel),
"ASI
Receive/Passthru"
should
be
shown.
