Programming Tip: If a symbology won't be used, we recommend turning it off
to minimize the chance of a misread.
Interleaved 2 of 5 is a continuous, twoĆwidth symbology capable of encoding
an even number of numerics. OddĆlength messages are usually padded with
a leading 0. Each pair of digits is represented by five bars and five spaces. The
bars encode the first digit: two of these five bars are wide, the other three are
narrow. Following each bar is a space; collectively, the spaces encode the
second digit of the pair. Interleaved 2 of 5 characters are spatially efficient for
the set of numerics.
The start/stop characters are short, but not secure. Their patterns can occur
erroneously in partial scans of a symbol. As a result Interleaved 2 of 5 is prone
to misreads when the scanning path does not include both quiet zones.
Default = On.
If the application requires the ability to read variableĆlength messages, or some
other fixedĆlength, then choose the minimum and Maximums accordingly. We
recommend setting the range [Minimum, Maximum]as small as the application
allows. Defaults on default chart (page NO TAG).
Bearer bars having a width comparable to the wide elements can be printed to
further enhance security.
Use of a check digit is optional in Interleaved 2 of 5. For applications requiring
enhanced security, symbols should be printed with a check digit using the
format described in the AIM specification, and the reader should be
programmed to verify its value. Since it is not considered part of the message
the check digit is not ordinarily transmitted, though the reader can be
programmed to transmit it. Default = Don't Verify and Don't Transmit...
To select digits 0 through 9 use the Programming Chart found on the
inside of the back cover of this menu. Scan the programming selection bar code
first, and then scan the bar code(s) representing the digits you wish to set.
