ADVANCED USE MANUAL DD700
1st character
<STX> (02H)
2nd character
<SP> (20H)
or <->
Space if the weight is positive
Minus sign if the weight is negative
3rd-9th
character
weight
10th character
<SP> (20H)
space
11th-12th
character
<um>
unit of measurement (kg, oz or lb)
As explained above, if the weight is
expressed in g or in t, the unit
of measure of the string only
occupies one
character (10th), subsequently the
numbering of the following
characters decreases by one unit.
13th-14th
character
<GR> or
<NT>
GR = gross weight
NT = net weight
15th-18th
character
<OVER> or
<ACPT> or
<UNDR>
OVER = OVER ACPT = WITHIN
UNDR = UNDER
19th character
<M> or
<R> or
<SP> (20H)
M = unstable weight
R = overload
SP = valid and stable weight. This
character is only there if the
protocol is cyclical, in all other
cases the numbering of the
following characters drops by
one unit.
20th character
<CR> (0DH)
21th character
<LF> (0AH)
2.2.9
CW String (**)
The CW string can only be selected in Verifica Peso/(checkweight) mode, and can have a length
varying between 15 and 17 characters.
This variation depends on:
the unit of measurement used to express the weight: if it is expressed with g or t, the unit of
measurement in the string only occupies one character, if it is expressed in kg, oz or lb the unit
of measurement occupies two characters;
type of protocol: if it is cyclical, there is a weight qualification character (unstable, overload, valid
and stable).
For simplicity, only the example of the CW string comprised of 17 characters is provided below,
where the weight is expressed in kg, oz
or lb and the protocol
is cyclical.
