GRYPHON™ D432/D432E

3.6.1Concatenation

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, see page 25, 27 and 32). 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:

One Code Per Scan

If the code resulting from the single decoding of an image belongs to one of the code families to be concatenated, it is saved to the Gryphon™ D432/D432E 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 48), this code will be sent in the output message.

All Codes Per Scan

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/D432E 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 previously 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" command is set to "Tx codes causing failure" (see page 48), the codes causing the concatenation failure will be sent in the output message.
