16 PowerScan™ M8500

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, see

"Configuration Using Code Symbols" starting on page 47 ). When enabling the delay one or

more global headers and terminators are add

ed 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 PowerScan™ M8500 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 fail-

ure" (see page 94), 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 PowerScan™ M8500 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

eviously 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 94), the codes causing the con-

catenation failure will be sent in the output message.
