Decode Options

Transmit UPC-E/UPC-A Check Digit
Select if decoded UPC symbols are transmitted with or without a check digit.

Convert UPC-E to UPC-A

Use this parameter to convert UPC-E (zero suppressed) decoded data to UPC-A format
before transmission. After conversion, data follows UPC-A format and is affected by UPC-
A programming selections (e.g., Preamble, Check Digit).

EAN Zero Extend

This parameter adds five leading zeros to decoded EAN-8 symbols to make them
compatible in format to EAN-13 symbols.
Xmit "No Decode" Message
This feature sets the scanner to transmit "NR" when a symbol does not decode. If Prefixes
and suffixes are enabled, they are appended around this message.
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.
Decode of symbols containing 2 or 5 supplementals is enabled separately. For example, if
"2 supplementals" is enabled, only those symbols with 2 supplementals are decoded. To
decode symbols containing 2 supplementals and 5 supplementals, both must be enabled.
If UPC/EAN without supplemental characters is selected and the scanner is presented with
a UPC/EAN plus supplemental symbol, the UPC/EAN is decoded and the supplemental
characters ignored. If autodiscrimination is chosen, the LS 1220, after additional
processing to ensure a good decode, transmits either.
Note: Select either read, or ignore supplemental characters (as
approprate for your application) to minimize the risk of invalid data
transmission. Autodiscrimination mode requires additional
processing to ensure a good decode.
