Programming
• Code 39 Full ASCII
The ASCII character set assigns a code to letters, punctuation marks, numerals,
and most control keystrokes on the keyboard.
The first 32 codes are non-printable and are assigned to keyboard control
characters such as BACKSPACE and RETURN. The other 96 are called
printable codes because all but SPACE and DELETE produce visible
characters. See the tables beginning on page 2-23
Code 39 Full ASCII interprets the bar code control character ($ + % /)
preceding a Code 39 symbol and assigns an ASCII character value. For
example, when Code 39 Full ASCII is enabled and a +B is scanned, it will
be interpreted as b, %J as ?, and $H emulates the keystroke BACKSPACE.
Scanning ABC$M will output the keystroke equivalent of ABC ENTER.
The LS 3603 will not autodiscriminate between Code 39 and Code 39 Full
ASCII.
• 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 will follow UPC
format and be 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.
Transmit “No Decode” Message
This feature gives you the option to transmit “NR” when a symbol does not
decode. Prefixes and suffixes enabled will be appended around this message.
