Parity
Sets the parity for communications. You can set Parity to none, even,
or odd.
PDF417
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.
Planet
SR61TA (area imager) and SR61TE (near-far range area imager) only.
Enables or disables decoding of Planet symbology. The United States
Postal Service (USPS) uses a combination of two tracking numbers
(the Postnet code and Planet code) to track a customer’s piece of mail.
A Planet symbol has 12 or 14 digits.
Plessey
Enables or disables decoding of Plessey symbology. Plessey code is
pulse-width modulated like most other bar codes and includes a start
character, data characters, an eight-bit cyclic check digit, a
termination bar, and usually a reverse start character. The code is
continuous and not self-checking. You need to configure two
parameters for Plessey code: Start Code and Check Digit.
Postamble
Sets the postamble that is appended to any data you scan. Common
postambles include cursor controls such as a tab or a carriage return
line feed. You can set up to 20 ASCII characters for Postamble.
