Code 128
Purpose: Enables or disables decoding of Code 128 symbology. Code 128 is a very high density
alphanumeric symbology that supports the extended ASCII character set. It is a variable
length, continuous code that uses multiple element widths.
Syntax: CHdata
Acceptable values for data are:
0 Disabled
1 Standard Code 128
2 UCC/EAN Code 128
8 ISBT Code 128
Note: For help configuring ISBT Code 128, see “ISBT Code 128” later in this chapter.
Default: Standard
Scan: One of these bar codes:
Disable Code 128 Enable Standard Code 128
*$+CH0* *$+CH1*
*$+CH0* *$+CH1*
Enable UCC/EAN Code 128 Enable ISBT Code 128
*$+CH2* *$+CH8*
*$+CH2* *$+CH8*
Notes: If you configure Standard Code 128, the terminal will not decode Function Code 1
characters in the first position of a bar code label. Any subsequent Function Code 1
characters are translated to the ASCII GS character as a separator for variable length
fields.
If you configure UCC/EAN Code 128, the terminal will decode a bar code label as
Standard Code 128 unless one of the first two characters are a start character and a
Function Code 1. In this case, the bar code label is processed as described next:
1. The Function Code 1 character is not transmitted.
2. The three symbology ID characters, ]C1, are transmitted.
3. The remaining Code 128 characters are decoded as Standard Code 128.
