Code 49

Code 49

The Code 49 barcode symbology is 2D stacked-linear barcode that can encode 128 character ASCII.

Also known as: USS-49.

Standards: ANSI/AIM BC6 - USS Code 49.

Data and Options

• The input can consist of any ASCII data.
• When the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters.
• When the parsefnc option is specified, non-data function characters can be specified by escape sequences:
  • ^FNC1: FNC1
  • ^FNC2: FNC2
  • ^FNC3: FNC3
• The sam option specifies this symbol is part of multi-part structured data held in up to nine "mode 3" symbols. For example sam=25 specifies this to be the second symbol in a group of five symbols.
• The concat option specifies that this symbol is an alphanumeric continuation symbol ("mode 1").
• The rows option specifies the number of rows in the symbol, between 2 and 8.
• If rows is unspecified the encoder will default to the smallest number of rows that can hold the given data.
• The rowheight option specifies the height of the bars in each row in points. The default is 10.
• The sepheight option specifies the height of the separator bars enclosing the rows in points. The default is 1.
