If the following data is encoded in a 128 symbol
{Start C}{Function 1} ]1710091510123456789012{Function 1}2002
where the first Function 1 after the Start C symbol indicates it’s a GS1 bar code and the second Function 1 is a delimeter after a variable length field. When a scanner reads this symbol it should output:
]C11710091510123456789012<GS>2002
Note the output starts with a [C1 indicating a Code 128 GS1 symbol and the second Function 1 code gets translated to an ASCII Group Separator character <GS>, or Hex 1D
The Xenon does not do this by default, but if you scan these two configuration labels, it will behave per the GS1 spec:
