3.6.1 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 in pars. 5.1). 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 Lynx™ 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", 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 Lynx™ 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", the codes causing the concatenation

failure will be sent in the output message.
