7.6 Multi-line Barcode Scanning
The scanner can scan up to 3 lines of bar codes in the readable area at any one time. You can specify the number of
lines to be scanned, the data output order and output format using the configuration software (ScannerSetting_2D).*
7.6.1 Number of lines
The number of lines allowed for multi-line barcode scanning is 2 or 3. This setting is essential.
7.6.2 Data output order
You can specify the data output order by designating code types*
1
, heading characters*
2
, or the number of digits to be
scanned*
3
.
*
1
Code types should be selected from readable bar codes you enable. This setting is essential.
*
2
Up to two heading characters can be specified. If a question mark (?) is specified, it acts as a wild card. This setting can be omitted.
*
3
The number of digits to be scanned varies depending upon the code type. This setting is essential.
Note:
The number of characters for Code 39 symbols should be specified including start and stop codes.
7.6.3 Output format
You can select either the header/terminator- or comma-delimited output format.
(1) Header/terminator-delimited output format
Specifying this format allows the scanner to output multiple lines of barcode data in succession in the data
transmission format selected (see Section 9.4) so that the headers and terminators act as delimiters. For UPC and EAN
codes, the number of digits will be omitted.
(2) Comma-delimited output format
Specifying this format allows the scanner to output multiple lines of barcode data delimited with commas in the data
transmission format selected (see Section 9.4). Note that the scanner outputs the code ID mark specified for the first
line barcode and the number of digits including the delimiter commas. The number of digits will not be omitted even
for UPC and EAN codes.
Note 1:
Bar code types specified for multi-line barcode scanning cannot be read individually.
Note 2:
The scanner cannot read multi-line barcodes of UPC/EAN with add-on.
Note 3:
If linear components in a UPC/EAN Composite symbol are specified for multi-line barcode scanning,
EAN.UCC Composite symbols including the specified linear components cannot be read.
7.7 Scanning an SQRC (Security QR Code) Symbol
An SQRC symbol refers to a security QR Code symbol that consists of public and nonpublic data. The nonpublic data
can be read only when the encryption key configured in the scanner matches the one in the SQRC symbol.
To read an SQRC symbol with the scanner, it is necessary to enable SQRC scanning ("SQRC symbols only" or "both
SQRC symbols and QR Code symbols") using the configuration software (ScannerSetting_2D). The following SQRC
related parameters can be also specified--"Data transmission after mismatch of encryption key," "Management of
encryption key," and "Data transmission of nonpublic data."
Note:
SQRC scanning requires configuring an encryption key beforehand with the SQRC configuration software
(SQRC Setting) separately prepared.
