null modem cable
A cable that connects two computers and allows transmission of data between
them without requiring a modem.
number pad
A set of keys on the reader that allows you to move the cursor around the
screen and to type numbers and mathematical symbols. The reader's number
pad is designed to work like the number pad on a regular PC keyboard.
One-Shot mode
See Scanner mode.
optical serial port
The reader's COM1 is an optical serial port. You can communicate through
COM1 using a communications dock, optical link adapter, or another reader if
you align the two readers' receive and transmit signals on their optical serial
ports.
optional back
Optional hardware that extends the features of the basic JANUS 2010 reader.
Two optional backs are available: the PCMCIA Back provides a Type II PC
card drive, and the RF Back provides RF communications.
PAK
Program Acknowledgment character. Sent from the reader when the received
IRL program compiles with no errors.
parameter
See configuration command.
parity
A system for encoding characters with odd or even bar code patterns. Parity
provides a self-checking feature in bar codes and other data transmission
techniques. Even parity characters have an odd number of binary ones in their
structure.
PC card
A PC card is similar to a floppy disk. You can use Type I or II memory PC
cards and Type II expansion PC cards. Memory cards provide additional disk
storage space, not more executable conventional memory. Expansion cards
(also called I/O cards) allow you to connect the reader to I/O devices. PC cards
were previously called PCMCIA cards.
