PW
(Note 4) (Note 5)
None OK/NG
(Note 2)
Save parameter values.
This command saves settings made with control
commands into the flash ROM. Without a PW command,
the scanner loses settings made with control commands
when it is turned OFF.
IS
See Parameter Details,
[8] given later.
OK/NG
(Note 2)
Play back an audio data file specified by index, with the
specified playback volume.
If the scanner receives two or more IS commands in
succession, it plays back the audio data file specified by
the last command.
VOLSND
See Parameter Details,
[9] given later.
OK/NG
(Note 2)
Specify the playback volume for an audio data file
specified by index.
Note
1)
When the power is ON, the scanner is ready to scan.
If the scanner receives an R command, sends the code data read, and receives Z and R commands with a code being
applied to the scanning window of the scanner, then it sends even the same code data twice. This is because the Z
command cancels the double-read prevention processing.
(Note
2)
If the scanner receives a control command successfully, it returns an "OK" response to the host. If the format or
parameter of the received control command is invalid, the scanner returns an "NG" response.
(Note
3)
The scanner can read codes even displayed on a mobile's LCD under some conditions.
(Note
4)
To make the scanner save settings made with control commands into the flash ROM, do not turn the scanner power
OFF until the host returns an "OK" or "NO" response. Doing so may cause the scanner to malfunction.
(Note
5)
The PW can save settings into the flash ROM a maximum of 1,000,000 times due to the restrictions on the flash
ROM.
