Codabar (NW-7 Format)
• Codabar (NW-7) has four different start/stop character schemes as shown above. The check digit is
optional and, if present, would be the last character.
• If the scanner is programmed to calculate the check digit and the bar code is not printed with a check digit,
the bar code will not be read.
8. Options for 2 of 5
2 of 5 Format (Standard and Interleaved)
Omron strongly recommends that the “Fixing the Number of Digits” featured on page 35 be employed
whenever 2 of 5 bar codes are used.
