Length Based Bar Code Stripping
Use this procedure to create symbology rules for two bar codes with the same symbol-
ogy but with different discrete lengths. This procedure is not applicable for bar codes
with variable lengths (falling between a maximum value and a minimum value).
Example
For the purposes of this example, the following sample bar code parameters will be
used – EAN 128 and Code 128 bar codes. Some of the bar codes start with ‘00’ and
some start with ‘01’. The bar codes are different lengths.
• 34 character length with first two characters = “01” (strip first 2 and last 18)
• 26 character length with first two characters = “01” (strip first 2 and last 10)
• 24 character length with first two characters = “01” (strip first 2 and last 8). This 24
character bar code is Code 128.
• 20 character length with first two characters = “00” (strip first 0 (no characters) and
last 4)
On the Data Options tab, set Enable Code ID to Custom.
Create four custom IDs, using 1 for EAN 128 bar code and 0 for Code 128 bar code.
• c1 = Code = ‘]C1’
• c2 = Code = ‘]C1’
• c3 = Code = ‘]C0’ (24 character bar code is Code 128)
• c4 = Code = ‘]C1’
