Operation
5.1
Switching on the modem. New
“Automatic
restart
after
shutdown”
feature
There
is
no
special
way
to
turn
the
modem
on:
just
apply
power
to
the
VIN
terminal
via
a
power
connector
(see
Section
4.1
).
The
modem
will
be
fully
operational
after
4
to
9
seconds.
Logging
onto
a
network
may
take
longer
than
this
and
is
out
of
the
modem’s
control.
The
Automatic
Restart
after
Shutdown
feature
is
enabled
as
part
of
the
default
factory
settings.
This
means
that
if/when
the
modem
has
to
be
switched
off,
due
to
a
critical
power
supply,
the
modem
will
restart
itself
within
a
few
seconds.
This
feature
allows
an
application
to
be
switched
on
all
the
time
and
also
allows
it
to
restart
itself.
The
Automatic
Restart
after
Shutdown
feature
cannot
be
disabled
in
the
base
MTX
‐
3G
‐
JAVA
and
ULP
models.
In
RS485
models
there
is
an
AUTO_ON
terminal
in
the
Power
Connector
(see
Section
4.1
)
which
allows
for
the
enabling
or
disabling
of
this
function.
In
all
other
models
this
feature
can
be
disabled
by
software
using
GPIO3
and
then
you
can
switch
on
the
modem
with
the
TURN_ON
pin
at
the
power
connector.
5.2
Switching off the modem
There
are
several
ways
to
switch
off
(power
down)
the
modem:
Using
the
TURN_OFF
pin
(see
section
4.1
to
see
the
terminals
that
use
it).
Continuously
pressing
the
TURN_OFF
pin
(for
at
least
1
second)
causes
the
modem
to
enter
power
down
mode.
Its
use
is
not
recommended
except
in
an
emergency.
A
delay
of
up
to
10
seconds
is
experienced
until
the
modem
logs
out
of
the
network.
The
RTC
stays
active.
AT^SMSO
command:
this
allows
the
modem
to
log
out
of
from
the
network
and
allows
the
software
to
enter
into
a
secure
state
and
save
data
before
disconnecting
the
power
supply.
A
delay
of
up
to
10
seconds
is
experienced
until
the
modem
logs
out
of
the
network.
The
RTC
stays
active.
In
ULP
models,
the
only
way
to
switch
off
the
modem
and
enter
into
the
Ultra
Low
Power
mode
is
to
clean
the
input
latches
and
execute
the
AT^SMSO
command.
