Features
The M2004-I418 differs from the standard in the
following ways:
• Plural Stage bar code decoding is support-
ed.
• Custom default parameter settings are im-
plemented.
• Supplemental Recognition Characters are
supported.
Plural Stage Bar Codes
A Plural Stage bar code is defined as multiple
barcodes that are printed in close proximity to
each other. They are usually arranged in a
vertical fashion (i.e. one above the other),
although this is not a requirement.
Two modes of plural stage decoding are
supported in this product:
• RC Mode requires the use of recognition
codes in order to decode plural stage bar
codes. Row recognition codes can be pro-
grammed by the user for use when the
scanner is in RC Mode. In this mode the
scanner supports 2-stage, 3-stage, and 4-
stage bar code reading, where the number
of the stage indicates the number of sepa-
rate bar codes that make up the plural
stage bar code set. See
Plural Stage Row
Recognition Codes on page 23 for details
regarding the format of the recognition
codes.
• NRC Mode does not require the use of rec-
ognition codes. In this mode, the number of
bar codes the scanner must decode prior to
transmitting is set through the
NRC Mode
Plural Stage Select parameter. This param-
eter can be set from 2 - 5 barcodes.
When the data is transmitted, formatted row 1
data is sent first, formatted row 2 is sent second,
etc. See
Plural Stage ADF Rule on page 21 for
