network
configuration.
This
will
have
to
be
loaded
manually
by
the
users
application
software.
Note:
RS485
settings
as
follows…
•
Local
=
Local
RS485
control
and
monitoring
of
all
ION
parameters
via
the
CobraNet™
RS485
port
(ie
serial
bridging
is
off).
The
Master/Slave
toggle
then
determines
whether
the
ION
is
slaved
to
a
separate
PC/Processor
or
acting
as
the
master
to
communicate
with
wall
plates
(TBA).
•
Bridge = Serial bridging, where the CobraNet™ RS485 port is simply a multidrop
bidirectional
serial
communications
channel.
The
data
at
the
CobraNet™
RS485
port
is
not
used
by
the
local
ION,
but
communicated
to
a
remote
device(s)
on
the
network.
This
is
the
standard
Cirrus
setup.
Master/Slave
also
has
no
effect
in
this
situation.
•
Remote = Remote control via serial bridging, ie a serial port on a remote
CobraNet™ interface can control and monitor the local ION (TBA).
Figure 4-3:
System settings page.
Notes:
•
All
RS485
settings
need
up
to
1
minute
to
establish
persistence,
as
they
are
stored
in
the
CobraNet™
flash.
If
the
ION
power
is
cycled
before
the
settings
are
stored
to
flash,
then
the
settings
will
be
lost.
•
The
RS485/CobraNet™
DIP
switch
on
the
rear
of
the
ION
should
be
set
to
CobraNet™.
If
it
is
set
to
RS485,
then
the
RS485
address
on
the
DIP
switches
