Note 1: When the code remains within the reading window, if the scanner receives the "Z" and then "R" commands after
the scanned data is transmitted by the receipt of the "R" command, the scanned data is transmitted again. This is
because the "Z" command clears the prevention of double scanning.
For the same reason, if the scanner enters the scanning standby mode by the receipt of the "Z" command before all
the blocks of a Structured Append Code are completely scanned, the Structured Append Code data are cleared.
However, even when "READOFF" or "LOFF" command is received instead of "Z" command, or "READOFF" or
"LOFF" instead of "R" command, operation will be the same.
Note 2: It may take a maximum of 100ms to run the command after receiving B1- B3, BH1-BH3, BM1-BM3, BL1-BL3,
LB, LG, LR, or VO command.
Note 3: The command "B1" (including BH1, BM1 and BL1) beeper beep time is based on the setting for the scan
complete sound and beeper beep time when scanning is complete.
Note 4: Parameter memory storage executed with the PW command can be performed up to one million times due to
restrictions on the number of times data can be written to the FLASH ROM.
Note 5: This can only be used when data verification scanning is not set.
Host
Scan fail
When set to Continuous reading mode 1 or 2, data is transmitted
when scanner enters Ready state without completing scanning in
Active state. Possible to select whether to transmit.
Match
Only if data output is set to "OK" when verified data matches, this
command will be transmitted when data scanned matches the master
code in the verification scanning mode.
Mismatch
Only if data output is set to "NG" when verified data does not match,
this command will be transmitted when data scanned does not match
the master code in the verification scanning mode.
Restores the parameter settings to default.
