8.5 When Parameter S.F. in section 7 is set to 3 :
The baud rate and data format are fixed with responses to serial commands being within 300
milliseconds. One second should be adequate for use as a time-out value by remote (controlling)
device.
8.5.1
The length of the weight field will be 7 digit weight data, one for minus sign, one for decimal point,
two for measure unit (e.g. “lb”, “kg”). Units of measure abbreviations are always lower case.
If the weight is overcapacity, the scale will return nine ‘^’ characters (the field of minus sign, decimal
point, weight data is filled by ‘^’).
If the weight is under capacity, it will return nine ‘-’ characters (the field of minus sign, decimal point,
and weight data is filled by ‘_’).
If the zero point has an error, it will return nine ‘-’ characters.
The character will be ‘-’ for negative weight or a space character for positive weight. Minus sign follows
after the first digit.
Useless leading zero before digits are suppressed.
8.5.2
Key to symbols used
<LF> Line Feed character (hex 0AH)
<CR> Carriage Return character (hex 0DH)
<ETX> End of Text character (hex 03)
<SP> Space (hex 20H)
H1H2H3 Three status bytes. Refer to Table1 for definition.
<p> Polarity character including minus sign for negative weight and a space character for positive
weight
W1-W7 weight data
<dp> decimal point
U1U2: measure units, kg, lb
