Bar Codes - 3
The Bar Codes - 3 Programming mode contains
programming parameters for Interleaved 2 of 5. Refer to
the Bar Codes - 3 worksheet in Appendix A.
The Interleaved 2 of 5 parameter controls reading
Interleaved 2 of 5 bar codes. You disable reading
Interleaved 2 of 5 bar codes by scanning the Hex 0 tag
and enable reading by scanning the Hex 1 tag. The
default is to enable reading.
If you choose to disable reading Interleaved 2 of 5 bar
codes, there are no other entries allowed for this
parameter. However, if you enable reading Interleaved
2 of 5 bar codes, you can program the following
parameters.
Bar Code Length
The Bar Code Length parameter option selects the
method for determining if an Interleaved 2 of 5 bar code
is a valid length. The Range Check method identifies a
length range by specifying the minimum and maximum
number of characters. The Specific Check method
identifies two specific bar code lengths by specifying the
number of characters in each. With this option, the
number of characters in all Interleaved 2 of 5 bar codes
must be one of the two numbers. Scan the Hex 0 tag to
use the Range Check method, scan the Hex 1 tag to use
the Specific Check method. The default is the Range
Check method.
