Metrologic Instruments IS1000 manual Interleaved 2/5

3.3.Interleaved 2/5

This symbology is only numeric and offers a very high density of characters per inch due to its interleaved encoding system. The decoding is very easy even if the symbols are poorly printed. These advantages make it very popular for industrial applications.

But to avoid missing characters when scanning is incomplete, it has to be used with fixed lengths (see pages 28 or 29) or variable lengths with a check digit (see page 30).

3.3.1.Fixed Length(s) Authorized and Set Upon First Reading(s)

The characters are interleaved (always paired), therefore it is necessary to define whether the number of significant characters is odd or even.

EVEN *

ODD

1 LENGTH FIXED AFTER THE FIRST READ *

3 LENGTHS FIXED AFTER

THE FIRST 3 READS

2 LENGTHS FIXED AFTER

THE FIRST 2 READS

4 LENGTHS FIXED AFTER

THE FIRST 4 READS

!Note:

In this mode, the code lengths are not saved after power-off.
