SERIAL DATA FORMAT
The serial data formats are defined during the setup and review functions. At these times, the
number of start, data and stop bits along with the baud rate is selected for the serial interface. Baud
rates of 1200, 2400, 4800, 9600 and 19.2K baud are supported. Refer to CALIBRATION section,
Configure Serial Port.
RECORD FORMAT
The information transmitted from the printer output port depends on the operation mode of the 748P
at the time the PRINT key is pressed as well as the print format entered. Refer to the
CALIBRATION, PRINT and FUNCTION key section of this manual for additional information on the
programming of the printer output format. Two general formats transmitted are shown below.
GROSS WEIGHT MODE: NET WEIGHT MODE:
*^CR ID^nnnnnn *^CR ID^nnnnnn
*^CR hh:mm *^CR hh:mm
*^CR mm/dd/yyyy** *^CR mm/dd/yyyy**
*^CR xxxxxx^LB^G
*^CR xxxxxx^LB^T ^(Man Wt)
*^CR xxxxxx^LB^N
*Determined by tab settings
**Domestic - dd/mm/yyyy = international
where:
nnnnnn = six (6) digits of numeric identification with leading zeros suppressed
hh = hours (refer to Setup for information on 12 or 24 hour time format selection)
mm = minutes (two (2) digits)
ss = seconds (two (2) digits)
MM = month (two (2) digits) (refer to Setup for information on date format
selection)
dd = day (two (2) digits)
yyyy = year four (4) digits)
ID = ASCII letters “I” and “D” to identify data as identification
LB = ASCII letters “L” and “B” to identify weighing units as pounds. May also be
KG for kilograms, OZ for ounces
xxxxxx = six (6) numeric digits of weight with decimal point if required and leading
zeros suppressed
G = ASCII letter “G” for gross weight
T = ASCII letter “T” for tare weight
N = ASCII letter “N” for net weight
CR = carriage return (followed by LF if Automatic Line Feeds was set to YES
during setup)
^ = space (hex 20)
LF = line feed
CONTINUOUS DATA OUTPUT
If, during setup and calibration, the answer to the prompt Sb400? is NO, the weight data will be
transmitted in the following format:
CRPzzzzzzDs^uu^m^^ETX
If the prompt Sb400? is answered YES, the weight data will be transmitted in the following formats:
Pxxxxxx^UU^M^SS^CR (no decimal point in weight display)
PxxxxxxD^UU^M^SS^CR (decimal point in weight display)
