Checksum Verification
: This parameter
specifies whether the scanner will perform
checksum verification when decoding
barcodes. If the checksum is incorrect, the
barcode will not be read.
•
Checksum Transmission
: This parameter
specifies whether the checksum character are
included in the data being transmitted.
•
Code Length Qualification
: Because of the
weak structure of the 2 of 5 codes, a partial
scan has a high probability of decoding as a
valid but shorter 2 of 5 codes (known as short
scan). To prevent this kind of undesired
reading, the
Code Length
settings can help to
insure that the correct code is read by
qualifying the allowable code length. Code
length parameters can be configured in two
ways :
Fixed Code Length
or
Max / Min
code length
. If the fixed code length is
selected, up to 2 fixed lengths can be specified.
And if max / min code length is selected, the
max length and the min length must be
specified, and the scanner will only accept
those codes with lengths fall between max /
min length specified.
•
Read Odd Number of Digits
: This parameter
is available only to the Interleave 25. This
parameter must be enabled in order to read
Interleave 25 labels which contain odd number
of digits.
4.4 Codabar
•
Start/Stop Transmission
: This parameter
specifies whether the start/stop characters of
Codabar are included in the data being
transmitted.
•
Start / Stop Selection
: Four different start /
stop pairs can be selected as start / stop
characters as listed below.
abcd / abcd
abcd / tn*e
ABCD / ABCD
