Direct Commands
Direct command allows the scanner to direct the start/end function operations. The direct command includes the followings:
Command
Start scanning (Software trigger) READON (Note 1)
End scanning (Software trigger) READOFF (Note 1)
Start scanning test
End scanning test
Start image memory output
(Note 1) The transmitted commands for scanning control can be changed. Default values are "READON" and
"READOFF".
(Note 2) This is the test scan count, and should be specified in the range nnn = 001 to 999. (However, continuous
testing is performed if "000" is specified.)
(Note 3) Specifies the image memory from nn = 00 to 99.
Indirect Commands
Indirect command allows the scanner to confirm the system settings or the setting contents. The command can be accepted
when receiving "START" from the host and ends receiving commands when receiving END reflected by the setting with
commands. The indirect commands include control command, scanning setting command, communication setting command,
image memory setting command, scanning test setting command and option setting command.
The commands are followings;
Note) Reply with NG even if the commands other than indirect commands are received until it ends with "END" after
starting the setting with "START".
Note) Indirect commands can not be operated during the scanning test.
Command
Initialize set value
Save set value（FLASH storage）
Reset software
(Note 1)
The system set values shall be returned to default.
(Note 2)
There may be times when commands are not accepted during the period from the receipt of the "DEFAULT
"or "SAVE" commands until a response is returned
(Note 3)
When executing the "RESET", the decoder will execute the same sequence as it resets the set value at power
application.
(Note 4)
No set parameter is stored in the QB30 without executing the "SAVE#n" command. If the "SAVE#n"
command is executed, the last set parameters are maintained even though the decoder is powered off and powered on again.
On the contrary, if the setting mode exits from the setting mode at the "END" command without executing the "SAVE#n"
command, the decoder operates based on the set parameters until the decoder is powered off, but when powered on again, the
last set parameters are canceled.
(Note 5)
The data is written to the flash memory. Writing should be performed up to a maximum of 100,000 times.
