Manual No. 25-ULGPMU01-01
2of5 Settings (continued)
Code 2of5 is a variable length symbology with an optional check digit and non printable start and stop character. Supported
characters include numeric digits 0 to 9.
The checksum is calculated as the sum modulo 10 of the numerical values of all the data characters. The following 2of5 codes are
supported.
Industrial 2of5 (D 2of5) - This symbology encodes a pair of digits in each symbol, the number of digits are therefore always an
even number. Information is carried in the bars and spaces. The start and stop pattern in not unique inside the code. It is therefore
essential to use the fixed length option to prevent partial reads.
Matrix 2of5 - This symbology encodes 1 digit in each character, the number of digits can therefore be an odd or an even number.
Information is carried in the bars and spaces.
String format - Industrial, Interleaved or Matrix 2of5:
Options for Code 2of5:
* Disable transmission of the check digit
* Enable check digit check
* Selection of the minimum number of data characters
* Disable space check for industrial 2of5
* Transmit S Code as Interleaved 2of5
*
Minimum data characters - Code 2of5 are checked for a minimum of 1, 3 or 5 characters as set by the user. If the number of
characters in the label is less than the number set, the label will be rejected. If the fixed length option is used for a Code 2of5 type
label, then such label will also be checked for fixed length.
Intercharacter gap check - This option enables the reading of Industrial 2of5 labels with a large or irregular spacing.
