RJ11
(all
other
models)
An
RJ11
6
‐
way
connector,
as
shown
and
described
below,
serves
as
a
means
of
supplying
and
controlling
DC
power
to
the
modem.
The
power
supply
voltage
(VCC)
required
by
the
modem
is
in
the
range
of
6.5
to
40VDC.
We
recommend
a
12V
DC
power
supply.
The
power
supply
has
to
be
a
single
voltage
source
capable
of
providing
a
current
peak
during
an
active
transmission.
The
uplink
burst
causes
strong
ripples
(drop)
on
the
power
lines.
By
default,
MTX
‐
3G
‐
JAVA
devices
are
shipped
to
automatically
switch
on
only
with
supply
at
PIN
1
and
PIN
6.
If
you
disable
the
“Automatic
power
up”
feature
you
will
need
to
use
the
additional
active
‐
low
control
signal
TURN_ON,
which
must
be
applied
for
a
time
of
0.2
seconds
or
greater.
