Configuring Your Decoder
4–34
Note: The layout of the label must be such that the distance d is less than or
equal to D for the scanner to scan all of Field #2. In addition, the line speed
must be constant.
MATCH COMPLETE (t) - This field sets the specific number of entries in
the match code table that must be matched to a package before a Match
Complete condition occurs. Match Complete is one of the six conditions that
can turn on an output (refer to the match code table information which
follows). You must enter a numeric value from 1 through 8.
Note: The Match Complete entry does not have to be the same as the Fields
Per Package entry. However, if the Match Complete entry is greater than the
Fields Per Package entry, a match complete condition will never occur.
Match Code Table
BAR CODE SYMBOLOGY (u) - When using the match code operation,
you must specify the type of symbology used. You can select from one of
the following symbologies: Code 39, Interleaved 2-of-5, Code 128, Codabar,
UPC-A, UPC-E, EAN-8, EAN-13.
MATCH CODE ENABLE (v) - Each of the match codes may be
individually enabled by selecting Y(Yes) in the enable field. Selecting
N(No) will disable the match code operation.
MATCH CODE (w) - In these fields, you may enter the code that you want
to match. You must enter the code as it will be transmitted to the host (e.g.
do not include check digits if you have selected to suppress the transmission
of the check digit in the decoder’s configuration). The decoder will compare
the match code with any decoded bar code data. If the decoded bar code data
matches the match code, a Match condition occurs. You can enter up to 32
ASCII characters in each of the eight fields.
Note: The ? character is a ”wild card” character that will result in a match
with any other ASCII character. You can enter a non-printable control
character as shown in Table 4.B.
Outputs
OUTPUT CONTROL (x)- These fields specify the conditions that must be
met to turn an output on. You can operate up to eight output modules based
upon a variety of conditions. You can select one of eight options for each
condition (Module position # 8 has nine options).
1) None: Selecting none will disable the output module.
2) Match Entry: Selecting this option will turn on the module whenever a bar
code matches the match code entry to the left of this field.
