remembers
things
like
this
so
you
don’t
have
to!
If
you
decide
to
undo
any
of
these
selections,
simply
press
the
left
arrow
to
return
to
the
Data
Protocol
screen
and
select
a
different
protocol.
Although
the
ADL
Vantage
radio
modem
supports
both
GMSK
and
4FSK
modulation,
you
cannot
select
modulation
type
with
the
user
interface.
The
radio
automatically
selects
the
appropriate
modulation
based
on
the
channel
bandwidth
of
the
radio’s
channel
table
(displayed
on
the
Device
Status
screen
as
“BW:
12.5
or
25
kHz”),
the
data
protocol
and
the
radio
link
rate.
If
you
want
to
select
a
modulation
type
first
and
then
an
appropriate
channel
bandwidth,
protocol
and
link
rate,
please
use
ADLCONF
to
configure
the
radio.
Indicator
LEDs
The
TX
LED
indicates
that
the
ADL
Vantage
is
broadcasting.
In
most
GPS
RTK
applications,
the
TX
LED
will
flash
approximately
once
per
second.
The
PWR
LED
indicates
the
power
status
and
also
provides
a
low
external
voltage
supply
indicator.
When
lit,
power
is
turned
on.
The
PWR
LED
will
blink
to
indicate
if
the
external
voltage
supply
is
approaching
the
minimum
value.
If
the
PWR
LED
does
not
respond
to
the
On/Off
button,
then
the
level
of
the
external
voltage
supply
should
be
inspected.
The
RX
LED
flashes
to
indicate
that
the
ADL
Vantage
is
receiving
signals
from
another
radio
or
from
a
source
of
interference.
The
default
is
Signal
received
,
but
you
can
reset
the
radio
so
that
when
its
RX
LED
flashes
it
means
Data
packets
received
.
You
can
reset
the
meaning
either
through
the
user
interface
or
with
ADLCONF
configuration
software.
During
normal
operation,
the
RX
LED
will
flash
at
a
once
‐
per
‐
second
rate
indicating
the
reception
of
transmissions
from
the
transmitting
radio.
If
the
RX
LED
is
on
continuously,
then
a
source
of
interference
may
be
impacting
the
ability
of
the
ADL
Vantage
to
receive
data.
Try
repositioning
the
antenna,
or
changing
to
another
channel
at
both
the
transmitter
and
receiver
to
reduce
or
eliminate
the
interference.
Enclosure
The
ADL
Sentry
enclosure
is
a
tough,
impact
‐
resistant,
aluminum.
It
is
further
protected
with
a
chemical
‐
and
scratch
‐
resistant
polyurethane
coating.
Elastomer
end
caps
provide
the
first
level
of
shock
protection
for
the
internal
components.
An
internal
isolation
system
reduces
the
effects
of
vibration
on
the
radio
receiver
board.
Antenna
Mount
The
integrated
antenna
mount
provides
an
industry
standard
TNC
‐
female
RF
connector
that
is
compatible
with
a
wide
range
of
mobile
whip
antennas.

ADL
Vantage
Battery/Charger

(PN
K01115)
includes
a
12
‐
Volt,
8
‐
AHr,
deep
‐
discharge,
lead
‐
acid
battery.
This
battery
provides
all

day
operation
for
the
radio
and
may
be
recharged
approximately
