The Interface parameters are: 
 
Connection details are: 
 
 
8.1  RS -232 connection  between  the Scale and  the Host : 
         DB9 female  RXD    pin  3         
T XD   pin  2         
GND   pin 5          
Note:  Pins 1,  4,  6,  7,  8 and 9 are not connected.  
 
The RS232 function will only operate if PH has been set to 0 or 2.  
 
  8.2  When Parameter S.F . in section 7 is set to 0 :  
No RS232 function. The scale  will not tr ansmit or receive any data although the 
scale is equipped with RS232.  The RS232 function can be only activated when  the 
scale is in normal weighing mode.

8. 3 When Parameter S.F . in section 7 is set to 1 :  
Continuous  output of the current displayed reading and unit, and  no data is 
received. The output format is as below:  
< reading, minus, decimal point, weight unit>GR  
Or < reading, minus, decimal point, weight unit>NT  
 
  8. 4 When Parameter S.F . in section 7 is set to 2 :  
Manually ou tputs displayed  data when PRINT  is  pressed . The output format is as 
below:  
< reading, minus, decimal point, weight unit>GR  
Or < reading, minus, decimal point, weight unit>NT  
 
 
8. 5 When Parameter S.F . in section 7 is set to 3 :  
 
Th e 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  a remote (controlling) device.  
 
8. 5.1  The length of the weight field will be a  7 digit weight data, one for minus sign,   
one for decimal point, two for measur ing 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, decim al 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 ha s an  error, it will return nine ‘ -’ characters.   
 
The character will be ‘ -’ for negative weight or a space character for positive 
weight.  A minus sign follows after the first digit.  
 
 U nused  leading zero’s  before digits are suppressed.  
 
8. 5.2  Key to symbols used  
 Line Feed character (hex 0AH)   
  Carriage Return character (hex 0DH)  
 End of Text character (hex 03)

If TARE function cannot be activated, it will return to current scale status.  
 
(5) Command: U  (55h 0dh)  
Response: Changes units of measure and returns scale  status with new units, 
the same as  pressing  the  UNIT  button. The new measur ing unit 
should be allowed to  be used  as per P11 setting.
