Datalogic Scanning D8530 User Manual

USING POWERSCAN® D8530 

 

 
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 27, 29 and 34). 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: 
 
 

 

•  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® D8530 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 50), 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 PowerScan® D8530 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 50), the 
codes causing the concatenation failure will be sent in the output message.
