Notes: If you configure Standard Code 128, the reader 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 reader 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.
