2.When P4 is set to 7: the protocol of RS232 is compatible to with NCI-SP1,
here is the details:
2.1) The baud rate and data format is fixed as per P5 and P6 setting. Responses to
serial commands will be immediate, or within one weight measure cycle of
the scale. One second should be more than adequate for use as a time-out
value by remote (controlling) device.
2.2) 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”). If the unit is
lb:oz, another two for “lb” and one for a space (<sp>) after lb. Units of
measure abbreviations are always lower case.
a) 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 is error, it will return nine ‘_’ characters.
b) The character will be ‘-’ for negative weight or a space character for positive
