6.2.6 ECI Protocol Output
Lets you determine whether to output data for ECI (Extended Channel Interpretation) protocol.
ECI is an embedded piece of information in a barcode that tells the scan engine details about
the references used to encode the data in the symbol. The scan engine uses this information to
automatically select matching options to decode the symbol. ECI protocol is supported in these
2D barcodes: QR Code, Data Matrix, Aztec Code, and Maxi Code.
The ECI protocol output is indicated with a backslash, a 6-digit number, and two backslashes.
If you do not want to output data for ECI protocol, change the AIM ID from ECI protocol
implemented to ECI protocol not implemented, delete the 6-digit number, and replace the two
backslashes with one backslash.
Output example:
Output data for ECI protocol: ]Q2\000001test\\test
Do not output data for ECI protocol: ]Q1test\test
*Backslash: ’ \ ’

6.2.7 Optical Character Recognition
You can configure the scan engine to use Optical Character Recognition (OCR) to identify a
specific pattern of characters in a barcode.
You can set up to 2 rows of characters containing up to 40 digits. For each digit, you can specify
one of these types of characters:
•
“A”: alphabetic character (letter)
•
“N”: numeric character (number)
•
“AN”: alphanumeric character (letter or number)
•
“SP”: space
•
One of these symbols:
!”#$%&’()*+,-./:;

?@[\]^_`{|}~
Those are ASCII 33 ~ 47, 58 ~ 46, 91 ~ 96 and 123~126
