Receiving Data From the Scale
The print or output format for the scale is user selectable. When a scale is connected
to a computer, it is suggested that "string format" be used. (This is selected through
the Print Format setup function described in Appendix II.) When this format is
selected, the scale will transmit whatever number or message appears on the scale
display upon request. (See the description of "Immediate and Continuous Print
Modes" later in this section.)
The "string format" output is shown below:
+/- 1 2 3 4 5 6 . SP c1 c2 c3 CR LF
The first six digits represent the number field. A sign + or - sign always precedes a
weight reading, and a decimal point are always transmitted, though their exact
location depends on the number transmitted. Numbers with less than six digits are
preceded by spaces and the sign is always adjacent to the leading digit. The
specific location of the decimal point depends on the precision of the number
transmitted.
“c1” is the “mode” character. It describes what the number being transmitted
represents. The following is a list of all possible characters sent in this digit:
CHARACTER MEANING
(space) Number field is a reading or message
I Reading is in the INT mode
G Number field represents GROSS weight
T Number field represents TARE weight
A Number field represents APW
M Number field represents ACCUM contents
For more information on printing the contents of the various registers, see the
“Printing Out Information” and “Print Format” sections of this manual.
“c2” is the “units” character. It describes the units of the number being transmitted.
