Code 128

The Code 128 parameter contains two selections: Disable and Enable. Disable reading Code 128 bar codes by scanning the Hex 0 tag and enable reading by scanning the Hex 1 tag. However, selecting the disable option does not prevent reading the programming tags that are Code 128. The default is to disable reading Code 128 bar codes.

Minimum Data Characters Allowed

The Minimum Data Characters Allowed refers to the Code 128 characters on a numeric-only Code 128 symbol. For example, given a numeric-only Code 128 symbol of 12 34 56 78, the Minimum Data Characters Allowed would be 4; each Code 128 character is composed of two numeric data characters. Enter your selection by scanning the appropriate hex tag (Hex 1 through Hex 5). The default is three.

UCC 128

The UCC 128 option refers to the Uniform Code Council Code 128 Data Formatter Start Code. Scan the Hex 0 tag to disable this function, or the Hex 1 tag to enable it. The default is disable.
