Scanning Split Qr Code Symbols - Denso AT10Q-SM User Manual

7.6 Scanning Split QR Code Symbols

QR Code symbology can split data into a maximum of 16 blocks and encode each of them into a split QR Code
symbol (model 1 or 2). Split QR Code scanning is possible only with the same QR Code model.
The scanner can scan split QR 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 split QR Code symbols read and then sends the edited data to the host computer. If
the total data volume of split QR Code symbols exceeds 8 kilobytes, a read error will result and the accumulated data
will be discarded.
Batch edit mode
If all the split QR Code symbols 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 QR Code symbol is read, the scanner sends the data read to the host computer.
When scanning split QR 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 split code scanning mode. When the scanner completes the
sequence of split code scanning, it beeps three times.
Note: If you scan any non-split QR Code symbol or a code other than a QR Code symbol midway through a sequence of
split QR Code scanning, the scanner cancels the split code scanning, discards the split QR Code data already scanned, and
sends the code scanned last.
Note: If the scanner switches to standby in auto-off mode (after approx. 5 seconds of holding down the trigger switch or
by releasing the trigger switch within 5 seconds) or the split 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 split code
scanning sequence.
Note: If you scan a split code symbol of any other QR Code before completion of the current scanning sequence, the
scanner discards the data already scanned and starts a new scanning sequence.
