Scanning Structured Appended Qr (Iqr) Code Symbols - Denso AT27Q-SB User Manual

6.6 Scanning Structured Appended QR (iQR) Code Symbols

QR Code symbology can split data into a maximum of 16 blocks and encode each of them into a Structured Appended
QR Code symbol (model 1 or 2) or Structured Appended iQR Code symbol. Structured Appended Code scanning is
possible only with the same Code model.
The scanner can scan Structured Appended Code symbols and restore them to the original data string in edit mode,
batch edit mode, and non-edit mode, which you can select using the QR-coded parameter menu or configuration
software (ScannerSetting_2D).
Edit mode
The scanner accumulates and edits Structured Appended Code symbols read and then sends the edited data to the host
computer. If the total data volume of Structured Appended Code symbols exceeds 8 kilobytes, a read error will result
and the accumulated data will be discarded.
Batch edit mode (for QR Code Model 1 and Model 2 only)
If all the Structured Appended Code symbol which is split in less than four to be scanned lie within the readable area,
the scanner reads them all once and then edits and sends them to the host computer.
Non-edit mode
Each time a single split Code symbol is read, the scanner sends the data read to the host computer.
When scanning Structured Appended Code symbols, the scanner beeps in a different way from usual. That is, when
the scanner reads the first split code, it beeps twice and enters the Structured Appended Code scanning mode. When
the scanner completes the sequence of scanning, it beeps three times.
Note: If you scan any non-split QR(iQR) Code symbol or a code other than a QR(iQR) Code symbol midway through a
sequence of Structured Appended Code scanning, the scanner cancels the Structured Appended Code scanning, discards
the Structured Appended Code data already scanned, and sends the code scanned last.
Note: If the scanner switches to standby in the Auto-off mode (after approx. 5 seconds of holding down the trigger switch
or by releasing the trigger switch within 5 seconds) or the Structured Appended Code scanning interval exceeds approx. 3
seconds in any trigger switch operating mode except Auto-off mode, then the scanner discards the data scanned and
cancels the Structured Appended Code scanning sequence.
Note: If you scan a Structured Appended Code symbol of any other Code before completion of the current scanning
sequence, the scanner discards the data already scanned and starts a new scanning sequence.
