2.8 Max. Code Length (Designated Digit )
Output Function
This function allows you to output the designated digit(s) as desired from the
readout bar code data. For example, from bar code data “49123456”, you can ex-
tract “1234” for output.
Setting digits to be output
Set the digits to be output as shown below. Individually set the digits for codes 1
to 4.
1. Set the direction to designate.
Set from which direction you want to start counting.
2. Set from which digit you want to begin designation (destination start digit).
3. Set how many digits you want to designate for output starting from the desig-
nation start digit in (2) (designation effective digits).
Example Designating and outputting “34” from bar codes “158423421” and “58423421”
Designate 2 digits starting from 3rd digit by counting reversely.
• Regardless of the designated direction, the data is output forward in the com-
munication application.
• When the bar code group includes those having different digits, take special
care on the designated direction when setting the digits to be output.
• When comparing to the preset data, all the digits of the bar code are used.
