Concatenation - Datalogic GRYPHON D412Plus Product Reference Manual

6. Code ID is attached to the resulting string;
7. Global headers and terminators are attached to the resulting string;
The codes to be sent to the host may also be selected or ordered depending on the following two
conditions:

Concatenation

It is possible to concatenate up to 4 different codes, set their length and enable the intercode
delay between them (the intercode delay is set in the specific interface parameters. When
enabling the delay one or more global headers and terminators are added to the decoded data.
The concatenation procedure may occur in different ways depending on the number of codes to
be decoded per image.

Product Reference Guide
one code per scan: Gryphon D432/D412Plus sends the code being closest to the image
center. If the "Central Code Transmission" command is enabled, only the code containing
the image center will be transmitted (see page 77);
all codes per scan: the codes to be sent to the host may be ordered either by length or by
symbology starting from the code being closest to the image center (see page 77). When
enabling both these criteria, codes belonging to the same symbology are sent to the host
depending on their length.
If the code resulting from the single decoding of an image belongs to one of the code fam-
ilies to be concatenated, it is saved to the Gryphon D432/D412Plus memory waiting for
other codes to complete the concatenation.
If the code belongs to the same family of a code previously saved, it overwrites the old one.
If the code resulting from the decoding does not belong to one of the code families to be
concatenated, it causes the concatenation failure and clears the temporary memory. If the
"Concatenation Failure Transmission" command is set to "Tx codes causing failure" (see
page 56), this code will be sent in the output message.
All codes resulting from the decoding of an image and belonging to one of the families to
be concatenated are saved to the Gryphon D432/D412Plus memory waiting for other
codes to complete the concatenation.
If one or more codes resulting from the decoding belong to the same family of codes pre-
viously saved, they overwrite the old ones.
When the image contains no code to be concatenated, the concatenation fails and the
reader temporary memory is cleared. If the "Concatenation Failure Transmission" com-
mand is set to "Tx codes causing failure" (see page 56), the codes causing the concatena-
tion failure will be sent in the output message.
