4. More Information for User Parameters Setting:
U5 to set serial communication output format:
(1). U5=0: No serial communication function. It will not transmit or receive any data
even if the scale is installed with serial communication hardware. Serial
communication function can be only activated when the scale is in normal
weighing mode.
(2). U5=1: Press PRINT key, the scale will output the current stable weight, weight
unit, and current Status data ; it does not receive any data . The output format is
as below:
<LF>< weight reading, minus, decimal point, weight unit><CR><LF>H1H2H3
<CR><ETX>
(3). U5=2: Press PRINT key, the scale will output the data of stable gross, tare, net
weight, weight unit and current status data. The format is as follows:
<LF><Gross: reading, minus, decimal point, unit><CR>
<LF><Tare: reading, decimal point, unit><CR>
<LF><Net: reading, minus, decimal point, unit><CR>
<LF>H1H2H3<CR><ETX>
The number of bytes used:
Weight reading ----------------------- 8bytes;
Minus ----------------------------------1byte;
Decimal point -------------------------1byte;
Weight unit ----------------------------2 or 5 bytes;
Current status (H1.H2.H3) --------- 3bytes
(4). U5=3: Continuously output of the current displayed reading, weight unit and
current status data, it does not receive any data. The output format is same as
U5=1.
(5). U5=4: Continuously output of the current gross weight, tare weight, net weight
data, weight unit and current status data, it does not receive any data. The output
format is same as U5=2.
(6).
U5=5: When the scale is stable, it will output the current displayed
reading ,weight unit, and current status data automatically one time, it does not
receive any data. The output format is same as U5=1.
(7). U5=6: When the scale is stable, it will output the current gross weight, tare weight,
net weight unit and current status data automatically one time, it does not receive
any data. The output format is same as U5=2.
(8). U5=7: Bio-Serial Communication: after receiving an available command, the
indicator will send out the corresponding messages.
5. More Details About Serial Communication
The following details contain more information for when U5 is set to 7:
a) The baud rate and data format is set by U6 and U7. Responses to serial commands
will be immediate, or within one weight measure cycle of the scale. One second is
adequate for use as a time-out value by remote (controlling) device.
b) The length of the weight field will be 8 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
