Interleaved 2 of 5

Enable/Disable Interleaved 2 of 5

To enable or disable Interleaved 2 of 5, scan the appropriate barcode below, and

select an Interleaved 2 of 5 length.

Set Lengths for Interleaved 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 I 2 of 5 to

any length, one or two discrete lengths, or lengths within a specific range. The

range for Interleaved 2 of 5 lengths is 0 - 55.



One Discrete Length - Select this option to decode only I 2 of 5 symbols

containing a selected length. Select the length using the numeric bar codes in

the Appendix of Numeric Bar Codes. For example, to decode only I 2 of 5

symbols with 14 characters, scan I 2 of 5 – One Discrete Length, then scan 1

followed by 4. To correct an error or to change the selection, scan the Cancel

barcode in Appendix B.



Two Discrete Lengths - Select this option to decode only I 2 of 5 symbols

containing either of two selected lengths. Select lengths using the numeric bar

codes in the Appendix of Numeric Bar Codes. For example, to decode only I 2

of 5 symbols containing either 2 or 14 characters, select I 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 barcode in Appendix B.



Length Within Range - Select this option to decode an I 2 of 5 symbol with a

specific length range. Select lengths using numeric bar codes in the Appendix

of Numeric Bar Codes. For example, to decode I 2 of 5 symbols containing

between 4 and 12 characters, first scan I 2 of 5 - Length Within Range. Then

scan 0, 4, 1, and 2 (enter a leading zero for single digit numbers). To correct an

error or change the selection, scan the Cancel barcode in Appendix B.



Any Length - Scan this option to decode I 2 of 5 symbols containing any

number of characters within the decoder’s capability.

NOTE

Due to the construction of the I 2 of 5 symbology, it is possible for a scan line

covering only a portion of the code to transmit as a complete scan, yielding less

data than is encoded in the bar code. To prevent this, select specific lengths (I 2 of 5

- One Discrete Length, Two Discrete Lengths) for I 2 of 5 applications.
