LS 1220 Product Reference Guide
Code Types
The scanner can be programmed to decode any or all of the following symbologies:
•
UPC Versions A and E (EAN 8 and 13)
•
Codabar
•
Code 39
•
Code 39 Full ASCII
•
Discrete 2 of 5
•
Interleaved 2 of 5
•
Code 128
•
MSI Plessey
•
EAN 128
•
Code 93
The scanner autodiscriminates between all of the above symbologies, except for Code 39
and Code 39 Full ASCII.
Code Lengths
Code lengths for Interleaved 2 of 5 and Discrete 2 of 5 only may be set for one or two
discrete lengths. The length of a code refers to the number of characters (i.e., human
readable characters) the code contains.
One Discrete Length - This option sets the scaner to decode only those codes containing
a selected length. For example, if D 2 of 5 is selected One Discrete Length, then scan 1, 4,
the only D 2 of 5 codes decoded are those containing 14 characters.
Two Discrete Lengths - This option sets the scanner to decode only those codes
containing two selected lengths. For example, if D 2 of 5 is selected Two Discrete Lengths,
then scan 0, 2, 1, 4, the only D 2 of 5 codes decoded are those containing 2 or 14
characters.
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 Table 8-5 on page 8-32.
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 is interpreted as b, %J as ?, and $H emulates the keystroke
BACKSPACE. Scanning ABC$M outputs the keystroke equivalent of ABC ENTER.
The LS 1220 does not autodiscriminate between Code 39 and Code 39 Full ASCII.
