1 byte output data was reserved for future applications. Currently, no function is assigned

Sequence
(comparison
function 2)
The parameter defines the sequence in which the
decoded barcodes are to be compared with the
RBC for comparison function 2.

(comparison
function 2)
The parameter defines under which conditions a
positive result for an ASCII character comparison
between decoded bare code and RBC occurs.

pattern length
The parameter defines the reserved storage
place per RBC. The RBCs themselves are depos-
ited in the following parameter (addr. 10).
If 0 is entered here, the individual RBCs are
stored one after another according to their stor-
age requirement.
If, for example, 16 is entered, a fixed amount of
16 bytes per RBC is set and only a total of 4 RBCs
can be defined.

pattern
In this parameter, the individual RBCs are depos-
ited one after another as hex values. For exam-
ple, if the comparison pattern length is defined as
8, RBC 1 is in bytes 0-7, RBC 2 in bytes 8-15 and
so on. In case RBC 1 uses only bytes 0 through 5,
bytes 6 and 7 have to be set to 0.
For each individual RBC, the code length is spec-
ified in the first byte and the code type in the sec-
ond byte (see
Modules 1-4 ) and the reference
code itself in the following bytes.
