Read Modes
8.1.2
Read modes includes “single read”, “multiple read 1”, “multiple read 2” and “continues read” modes.
Single read in a single trigger
Multiple read in a single trigger, the scanner saves
the read data in memory to not read the same data.
Multiple read in a single trigger, the scanner read the
same data.
Reads continuously even with the same code. Limit
to testing etc. to operate.
● Single Read
The scanner starts reading after a trigger until a barcode is successfully decoded or until the read
time expires. (See 6.1.4)
● Multiple Read 1 (Do not read the same data)
The scanner starts reading after a trigger and stays reading even after a barcode is successfully
decoded, until the read time expires. To prevent that a barcode is read twice, the scanner saves the
read barcodes in memory and checks if it has been read before. The list in memory is 20 barcodes
long so after 20 different barcodes, the same barcode can be read again.
If there is more than one code within the read area, as in the following figure, this read mode is
helpful to prevent reading the same code twice.
Example: Read multiple codes continuously with a single trigger.
To prevent that a barcode is read twice, the scanner saves
the read barcodes in memory and checks if it has been read
before.
To set the number of codes to be saved in the memory to prevent that a barcode is read twice, use
the following command.
Multiple Read 1
Number of codes
not read the same
data
Set the number of codes to be
saved in the memory to prevent
that a barcode is read twice.
Set; a:100 digits / b:10 digits /
c:1 digit
Default: 20
Effective range:
1 to 200
