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
extract “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 how many digits you want to designate for output starting from the designa-

tion start digit in (2) (designation effective digits).

* The actual setting order is (1) (3) (2).

3. Set from which digit you want to begin designation (destination start digit).

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 communica-
tion 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.
