5-48 Chapter 5: Programming
The
RS232
Terminator
Byte
programming
mode
controls
the
use
of
terminator
bytes.
If
an
RS232
Terminator
Byte
is
used,
it
goes
at
the
end
of
the
message
sent
to
the
host
terminal.
If
a
BCC
is
included,
it
follows
the
Terminator
Byte
and
includes
the
Terminator
Byte
in
the
calculation.
Refer
to
the
“Parameter
Defaults”
section
earlier
in
this
chapter
for
the
factory
defined
default
value
of
each
programming
parameter.
Terminator Byte
There
are
two
RS232
Terminator
Bytes
available–the
second
Terminator
Byte
being
a
direct
entry
only.
Therefore
after
programming
the
First
Terminator
Byte
Hex
2
,
Hex
3
and
Hex
C
must
be
scanned
to
be
able
to
program
the
Second
Terminator
Byte.
ASCII Code
The
ASCII
Code
parameter
for
RS232
Terminator
Byte
and
Prefix
Byte
has
the
same
function.
Refer
to
the
“RS232
Prefix
Byte”
section
of
this
chapter
for
more
information.

messages.
The
firmware
is
programmed
to
accept
one
parameter
at
a
time
and
then
leave
this
programming
mode.
Therefore,
each
of
the
parameters
must
be
programmed
separately.

in

for
the

defined
default
value
of
each
programming
parameter.
