TELNET
Typically,
in
Windows
OS
you
use
the
free
WinDiscovery
app
to
establish

configuration.
However,
in
Windows,
Linux,
UNIX,
Macintosh
and
other
operating
systems
you
may
use
Telnet
to
configure
the
GMR,
as
a
standard
feature.
Telnet
is
a
communication
protocol
in
the
TCP/IP
suite
that
uses

Let’s
say

entering
“telnet
123.123.123.123”
or
by
entering
“cmd”
and
then
entering
“telnet
123.123.123.123”
in
the
window
that
appears,
called
a
command
window.
A
banner
of
information
appears,
listing
the
GMR’s
name
and
essential
network
attributes.
You
are
prompted
to
enter
the
password.
It
is
“
public”
by
default.
The
same
password
is
used
by
telnet
and
WinDiscovery.
After
logging
in
one
controls
the
GMR
by
issuing
commands.
A
list
of
them
is
displayed
by
entering
“
?
”.
The
commands
available
depend
on
what
is
installed
in
the
device.
Each
command
has
options,
which
are
described
by
entering
the
command
followed
by
“
?
”.
