[Function] 
This is a control function to specify data to be sequentially incremented or decremented. 
In the data stream this command should be placed before EPC write command.  
 
 
[Format] 
 
    <F> a a a a b c c c c (, dd, e e, f) 
 
[Parameters] 
 
 
aaaa  Number of times to repeat the same data : 0001-9999 
 
b       Plus or minus symbol (+ for increments; - for decrements) 
 
cccc  Value of step for sequence (0001-9999) 
 
,dd  Number of digits for sequential numbering (01-99), if these digits are left out, the default is 8. 
 
,ee  Number of digits free from sequential numbering (00-99) starting with the rightmost position. 
If these digits are left out, the default is 0.   
 f  Decimal or Hexadecimal : 0 = decimal  
        1= Hexadecimal  
         When this digit is left out, the default is 0.
