Bar code types
During installation, the type of bar code used is defined for each mode. The Bar Code Reader is capable of reading and decoding three different types of bar codes.
∙Code 3 of 9 — also known as Code 39, is a widely used code in which 9 bars or spaces comprise the characters, 3 of which are wide.
∙Interleaved 2 of 5 — or I 2 of 5, is a compact, interleaved code for numeric characters only. Each digit is represented by 5 bars or spaces, 2 of which are wide.
∙Codabar — similar to Code 3 or 9, but not as widely used. Codabar includes only numeric and special characters.
