Full Duplex
Simultaneous, two-way, independent transmission in both directions.
Host
A computer that serves other terminals in a network, providing services such as network
control, database access, special programs, supervisory programs, or programming
languages.
Interface
A shared boundary defined by common physical interconnection characteristics, signal
characteristics and meanings of interchanged signals.
LED (Light Emitting Diode)
A low power electronic device that can serve as a visible or near infrared light source when
voltage is applied continuously or in pulses. It is commonly used as an indicator light and
uses less power than an incandescent light bulb but more than a Liquid Crystal Display
(LCD). LEDs have extremely long lifetimes when properly operated.
Parameter
A value that you specify to a program. Typically parameters are set to configure a device to
have particular operating characteristics.
Picket-Fence Orientation
When the barcode’s bars are positioned vertically on the product, causing them to appear as
a picket fence. The first bar will enter the scan window first. See par. 6.2.2.
Pitch
Rotation of a code pattern about the X-axis. The normal distance between center line or
adjacent characters. See pars. 3.2.1 and 3.4.
Position
The position of a scanner or light source in relation to the target of a receiving element.
Protocol
A formal set of conventions governing the formatting and relative timing of message
exchange between two communicating systems.
Resolution
The narrowest element dimension, which can be distinguished by a particular reading device
or printed with a particular device or method.
RS232
Interface between data terminal equipment and data communication equipment employing
serial binary data interchange.
RS485
Interface that specifies the electrical characteristics of generators and receivers for use in
balanced digital multipoint systems.
Scanner
A device that examines a printed pattern (barcode) and either passes the uninterpreted data
to a decoder or decodes the data and passes it onto the Host system.
