User's Manual

6. Symbology Parameters
This section describes user configurable parameters that are pertaining to barcode
symbologies.
6.1 Code39
• Standard / Full ASCII Code 39 : User can choose to read either Standard
Code 39 or Full ASCII Code 39 by configuring this parameter.
• Start/Stop Transmission : This parameter specifies whether the start/stop
characters of Code 39 are included in the data being transmitted.
• 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.
6.2 Italy / French Pharmacode
For Italy /French Pharmacode, there is always a checksum character included in the
barcode. So the checksum verification is always performed when decoding these
symbologies. User though can choose whether the checksum character is to be
transmitted or not. The start / stop transmission of this code shares the same setting
of Code 39.
• Checksum Transmission: This parameter specifies whether the checksum
character is included in the data being transmitted.
6.3 Industrial / Interleave / Matrix 25
• Start / Stop Selection: This parameter provides the readability of all 2 of 5
symbology variants. For example, flight tickets actually use an Industrial 25
barcode but with Interleave 25 start / stop. In order to read this barcode, the
start / stop selection parameter of Industrial 25 should set to ‘Interleave
25.
• 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 is 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.
6.4 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
6.5 UPCE
• System Number Selection: The UPCE comes with 2 flavors : 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.
6.6 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.
