To enter an ID# from a computer, send the following string to the scale:
/ [string identifier] $S
The ID START (or introducer), “/”, instructs the scale to ignore subsequent charac-
ters as commands. The ID FINISH (or terminator), “$”, instructs the scale to interpret
subsequent characters as commands. The ID# entry command, “S”, instructs the
scale to enter the string identifier into the ID# register.
The string identifier may consist of any uppercase ASCII character (A-Z), any
number (0-9), a space, or a hyphen (-). It may be up to 25 characters in length.
Lowercase ASCII characters (a-z) are translated into uppercase by the scale. All
other characters are ignored by the scale.
DO NOT SEND A CARRIAGE RETURN, CR, OR A LINE FEED, LF, DURING OR
AFTER THE STRING IDENTIFIER.
After receiving the ID START character, the scale accepts the ASCII DEL (hex 7F) as
a rubout/backspace. It deletes the last entered character from the ID# entry.
When interfacing with the Setra Auto Count 200 system, a space SP must be
included after the ID START character and after the ID FINISH character for Code 39
bar codes.
In addition to ID, other registers are available for storing information such as descrip-
tion and lot #, etc. For additional information, please refer to the Auto Count 200
manual.
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.
