• Decode Options (Continued)
Decode UPC/EAN Supplemental
Select whether UPC/EAN is decoded with or without supplemental
characters. Supplementals are additionally appended characters (2 or 5)
according to specific code format conventions (e.g., UPC A+2, UPC E+2, EAN
8+2). If UPC/EAN with supplemental characters is selected, UPC/EAN
symbols without supplemental characters won't be decoded. If UPC/EAN
without supplemental characters is selected and the scanner is presented with
a UPC/EAN plus supplemental symbol, the UPC/EAN will be decoded and
the supplemental characters ignored. If autodiscrimination is chosen, the
LS 3603 will, after additional processing to ensure a good decode, transmit
either. (NOTE: In order to minimize the risk of invalid data transmission, it
is recommended that you select whether to read or ignore supplemental
characters.)
Code 39 Check Digit
When enabled, this parameter checks the integrity of a Code 39 symbol to
ensure it complies with the modulo 43 check digit algorithm.
ITF-14/EAN-13 Conversion
If your terminal supports EAN-13, this feature converts a 14 character I 2 of 5
code into EAN-13, and transmits to the host as EAN-13. In order to accomplish
this, the I 2 of 5 code must be enabled, one length (either LENGTH 1 or
LENGTH 2) must be set to 14, the code must have a leading zero and a valid
EAN-13 check digit.
MSI Plessey Check Digit
One or two digits at the end of the bar code that check the integrity of the data.
At least one check digit (default) is always required. Check digits are not
transmitted with the data.
MSI/Plessey 2 Check Digit Algorithm
When the two MSI/Plessey check digits option is selected, an additional
verification is required to ensure integrity. Either of two algorithms may be
selected; Mod10 - Mod10 (default), or Mod11 - Mod10.
