Detector
Configuration
The
RS
‐
485
connection
from
the
flame
detector
to
the
host
PC
allows
the
Communicator
software
to
be
used
to
adjust
the
detector’s
operational
settings.
Install
the
Communicator
software
on
the
host
PC;
then
open
the
software
and
follow
the
steps
below
to
configure
the
flame
detector.
1.
Before
attaching
the
USB
to
RS
‐
485
converter
to
the
host
PC,
click
the
Com
Port
drop
‐
down
to
display
the
list
of
available
com
ports.

2.
Attach
the
USB
to
RS
‐
485
converter
to
the
host
PC’s
USB
port;
then
select
the
newly
available
port
from
the
drop
‐
down
list
and
click
the
chain
link
icon
to
attempt
to
connect
to
the
flame
detector.
3.
The
485
Port
indicator
should
change
from
red
to
green
to
indicate
a
successful
connection
to
the
detector.
As
long
as
the
485
port
indicator
is
green,
the
connection
to
the
detector
is
active.
If
red,
communication
with
the
detector
has
been
lost.
Once
communication
is
established,
the
software
will
retrieve
the
diagnostic
data
about
the
state
of
the
detector
and
will
display
the
configuration
parameters
on
the
Configure
tab
(Figure
5).
