PDF417

PDF417 is only supported on the SF51 with PDF version.

Enables or disables decoding of PDF417 symbology. The

PDF417 symbology is a stacked 2D symbology that allows you to scan across rows of code. Each row consists of start/stop characters, row identifiers, and symbol characters, which consist of four bars and four spaces each and contain the actual data.

This symbology uses error correction symbol characters appended at the end to recover loss of data.

Macro PDF417, a feature of PDF417, extends the capability of

PDF417 by allowing up to 99,999 PDF417 symbols to be used to store data. The symbols are concatenated as they are scanned and can be scanned in any order.

You need to configure two parameters for Plessey code: Start Code and Check Digit.
