Performing
a
Loopback
Test
on
the
Spectre
Cellular
Router
(v2)
Please
Note
This
procedure
will
explain
how
to
perform
a
RS
‐
232
loopback
test
using
the
DB9
to
RJ45
cable
(Part
Number
KD
‐
2)
that
comes
with
your
Spectre
Cellular
Router
(v2).
If
you
do
not
have
this
cable,
then
you
can
pinout
a
pigtail
using
an
Ethernet
cable.
Link
to
the
cable
pinout
can
be
found
here

This
procedure
was
completed
using
model
RT3G
‐
302.
Please
power
up
your
unit
and
connect
the
KD
‐
2
to
your
router.
For
this
test,
I
will
be
using
PuTTY.
However,
you
can
use
any
Terminal
Emulator
Program.
1.
Connect
to
the
cellular
router’s
webpage.
If
it
is
still
set
at
default,
then
the
IP
address
will
be
192.168.1.1.
Once
the
page
loads,
you
should
be
in
the
General
Status
section.
2.
On
the
left
side
of
the
web
page,
there
is
a
configuration
section.
Please
click
on
the
appropriate
Expansion
port
for
your
router.
More
specifically,
there
should
be
a
label
on
the
back
of
the
router
that
tells
you
what
expansion
module
is
in
what
port.
For
example,
the
label
on
the
router
I
am
using
for
this
test
tells
me
port
2
is
the
RS
‐
232
port.
Thus,
I
will
open
Expansion
port
2.
