(Note 1) If the scanner receives the R command twice with the reading window being applied to a code (for example,
it receives the R command, sends the code data read, and receives the Z and R commands), it will send even the same
code data twice. This is because the Z command cancels the duplication prevention processing.
In split QR Code scanning operation, if the scanner receives the Z command and switches to standby before scanning
a set of split QR Code symbols, the duplication prevention processing will be canceled. The code data that has been
read halfway will be discarded.
The READOFF and LOFF commands produce the same result as the Z command, the READON and LON commands,
the same result as the R command.
(Note 2) When the scanner is on standby, pressing the trigger switch may light the LEDs momentarily, but the scanner
cannot scan codes.
(Note 3) After receipt of one of the B1 through B3, LB, LG, LR and VO command, the scanner may need a maximum
of 100 ms to execute the command.

Request for software version
<Response from the scanner> Ver.n.nn
where n.nn is version number (Ex. Ver.1.00)
Request for the parameter setting version
This command checks the version of the parameter settings made
in the scanner when the scanner is linked with the configuration
software (ScannerSetting_2D).
<Response from the scanner> Ver.n.nn.mm
where n.nn.mm is version number (Ex. Ver.1.00.00)
and mm is parameter setting version.
Scanning failure
When the scanner (which is ready to scan) cannot complete
scanning and switches to standby, it sends the ERROR command
as long as the trigger switch control is set to continuous reading
mode 1 or 2. Whether or not to send this command can be
selected.
Verification match
If code data scanned matches master data in data verification
mode, the scanner sends this command as long as the OK
transmission is enabled for a match.
Verification mismatch
If code data scanned does not match master data in data
verification mode, the scanner sends this command as long as the
NG transmission is enabled for a mismatch.
