Application Creation
Bar code properties (cont.)
Double Modulo 10
Enables the Optimus to scan and decode bar code that contain two Modulo 10
check digits.
Modulo 11 & 10
Enables the Optimus to scan and decode bar code that contain the Modulo 10 and
11 check digit. Note: If the checksum is incorrect, the bar code won’t be read.
Checksum Transmission
The developer can control how the checksum is transmitted by configuring these
parameters.
1. Last digit not transmitted
2. Transmitted
3. Last 2 digits not transmitted
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 code. 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
If the fixed code length is selected, up to 2 fixed lengths can be specified
Max / Min code length
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 that fall
between the max / min length specified in the Length setting.
Length
The min and max length the length qualification setting references to qualify a bar
code as a valid bar code.
Italian / French Pharma-code
For Italian French Pharmacode, there is always a
checksum character included in the bar code. So the
checksum verification is always performed when decoding
these bar codes. The 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
Setting specifies whether the checksum characters are included in the transmitted
data.
