23. Details about Serial Communication
23.1 COM1 is RS232, communication wires come from RS232 connector, and TXD0, RXD0 and GND are
used. Please refer to section 24.5 connector details
23.2 COM2 is USB used as a virtual RS232, communication wires come from USB connector, and TXD1,
RXD1 and GND are used, Please refer to section 24.6 for connector details.
23.3 The baud rate and byte format is set by USER-COM1/2-BAUD.RT and USER-COM1/2-BYT.FMT.
Responses to serial commands will be immediate, or within one weight measure cycle of the scale. One
second should be adequate for use as a time-out value by remote (controlling) device.
23.4 The length of each item in a transition string:
23.4.1 Reading data --- 6bytes
Data polarity ----1byte: “-” for negative, and followed the first digit; “ ” for positive.
Decimal point ---1byte: “.”
Measure unit ----1-5bytes:“ lb”,“ kg”, “lb:oz”, “pcs”,“%”, Units are always lower case, left aligned
Current status-- 4bytes
23.4.2 If the weight is overcapacity, the scale will return eight “^” characters (the field of polarity, decimal
point, weight data is filled by “^”).
23.4.3 If the weight is under capacity, it will return eight “_” characters (the field of polarity, decimal point,
and weight data is filled by “_”).
23.4.4 If the zero point is error, it will return eight “-“ characters (the field of polarity, decimal point, and
weight data is filled by “-”).
23.4.5 Useless leading 0 before digits is suppressed. Reading weight is right aligned.
