Set Lengths for Discrete 2 of 5

The length of a code refers to the number of characters (i.e., human readable characters), including check digit(s) the code contains. Set lengths for D 2 of 5 to any length, one or two discrete lengths, or lengths within a specific range.

•One Discrete Length - Select this option to decode only D 2 of 5 bar codes containing a selected length. Select the length using the numeric bar codes in Appendix E, Keypad. For example, to decode only D 2 of 5 bar codes with 14 characters, scan D 2 of 5 - One Discrete Length, then scan 1 followed by 4. To correct an error or to change the selec- tion, scan the CANCEL bar code located in Appendix E, Keypad.

•Two Discrete Lengths - Select this option to decode only D 2 of 5 bar codes contain- ing either of two selected lengths. Select lengths using the numeric bar codes in Appen- dix E, Keypad. For example, to decode only those D 2 of 5 bar codes containing either 2 or 14 characters, select D 2 of 5 - Two Discrete Lengths, then scan 0, 2, 1, and then 4. To correct an error or to change the selection, scan the CANCEL bar code located in

Appendix E, Keypad.

•Length Within Range - Select this option to decode a D 2 of 5 bar code with a spe- cific length range. Select lengths using numeric bar codes in Appendix E, Keypad. For example, to decode D 2 of 5 bar codes containing between 4 and 12 characters, first scan D 2 of 5 - Length Within Range. Then scan 0, 4, 1, and 2 (single digit numbers must always be preceded by a leading zero). To correct an error or change the selection, scan the CANCEL bar code located in Appendix E, Keypad.

•Any Length - Scan this option to decode D 2 of 5 bar codes containing any number of characters within the scanner capability.

	Due to the construction of the D 2 of 5 symbology, it is possible for a scan
	line covering only a portion of the code to be interpreted as a complete scan,
	yielding less data than is encoded in the bar code. To prevent this, select
	specific lengths (D 2 of 5 - One Discrete Length - Two Discrete Lengths) for D
