10.8.2 Cardinal 738 Indicator
Sample string for the Cardinal 738 indicator:
<CR><POL><wwwwww><S><SP><units><SP><G/N><SP><SP><EOL>
880 stream format configuration:
<CR><P><W07..><S><SP><U><SP><M><SP2><03>
Table 10-8. Cardinal Sample String Identifiers
Identifier Description
<CR> Carriage Return
<POL> Cardinal uses + for positive and – for negative, so the stream polarity tokens need to reflect this. The EDP
commands for the 880 are STR.POS=+ and STR.NEG= –.
<wwwwwww> The <W07..> identifier that the 880 recognizes indicates seven digits of weight with a decimal and leading
zeroes, with the decimal being sent at the end of the weight. Valid characters are W, w, G, g, T, t, N, or n
(lower case indicates left justified). W indicates current weight, G gross weight, N net weight, T tare weight.
/P and /S can be used to specify primary or secondary.
Minus indicates sign inclusion, while (0) indicates leading zeros. First digit indicates field width in
characters. Decimal indicates floating decimal point. Decimal with subsequent digit indicates fixed decimal
with n digits to the right of the decimal. Two consecutive decimals (for example, <W06..>)
send the decimal point even if it falls at the end of the transmitted weight field.
<S> There are four possible tokens for status bits that can be used: motion, out-of-range, valid, and invalid. In
the Cardinal, m indicates motion, o indicates out-of-range, and a space is used for valid or invalid weights.
The commands to set these tokens in the 880 are STR.MOTION=m, STR.RANGE=o, STR.OK= ,
STR.INVALID= .
NOTE: Although it appears that there are no commands for OK and INVALID, there is a space entered with
the keyboard before pressing the ENTER key.
<SP> Space
<units> The Cardinal uses two-character, lower-case units identifiers. The commands to set these tokens in the
880 include: STR.PRI=lb (options: kg, g, tn, t , gr, oz, or sp), STR.SEC=kg (options: lb, g, tn, t , gr, oz, or
sp).
<SP> Space
<G/N> The mode used for Cardinal is g for gross and n for net. These tokens are set using the STR.GROSS=g
and STR.NET=n tokens.
<SP> Space
<SP> Space
<EOL> The end of line character is an ETX in this case so the hex value of <03> is entered in the string.
