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.
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
ABCD / TN*E
4.5 UPCE • System Number Selection: The UPCE comes with 2 options:
System Number 0 and System Number 1. These two differ in the
way data are encoded. The system number 1 is the new UPCE
extension to the ordinary UPCE (system number 0). User can have
the choice of enabling both system numbers, or just system number
0.
Warning: Because of the way system number 1 is encoded, if both
system numbers are enabled, user might suffer from short scanning
UPCA or EAN13 into UPCE system number 1 barcodes.
• Convert to UPCA: If this parameter is enabled, the UPCE read will
be expanded into UPCA, and the following processing will follow the
parameters configured for UPCA.
• System Number Transmission: If this parameter is enabled, the
system number will be included in the data being transmitted.
• Checksum Transmission: If this parameter is enabled, the
checksum character will be included in the data being transmitted.
10
4.6 EAN8 • Convert to EAN13: If this parameter is enabled, the EAN8 read will
be expanded into EAN13, and the following processing will follow the
parameters configured for EAN13.
• Checksum Transmission: If this parameter is enabled, the
checksum character will be included in the data being transmitted.
4.7 UPCA • Convert to EAN13: If this parameter is enabled, the UPCA read will
be expanded into EAN13, and the following processing will follow the
parameters configured for EAN13.
• System Number Transmission: If this parameter is enabled, the
system number will be included in the data being transmitted.
• Checksum Transmission: If this parameter is enabled, the
checksum character will be included in the data being transmitted.
4.8 EAN13 • ISBN / ISSN Conversion: If these parameters are enabled, the
scanner will convert the code read into ISBN or ISSN code if the
formats are correct (EAN13 codes start with 978 or 979 for ISBN,
and 977 for ISSN).
• Checksum Transmission: If this parameter is enabled, the
checksum character will be included in the data being transmitted.
4.9 MSI • Checksum Verification: Three kinds of checksum calculations can
be implemented into MSI code: Single Modulo 10, Double Modulo
10, or Modulo 11 & 10 checksum. If the checksum character is
incorrect, the barcode will not be read.
• Checksum Transmission: User can control how the checksum is
transmitted by configuring this parameters.
1) Transmitted
2) Last digit not transmitted
3) Last 2 digits not transmitted
• Code Length Qualification: Because of the weak structure of the
MSI code, a partial scan has a high probability of decoding as a valid
but shorter MSI codes (known as short scan). To prevent this kind of
undesired readings, the Code Length settings can help to ensure
that the correct code is read by qualifying the allowable code length.
Code length limitations can be set in 2 ways: Fixed Code Length
