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.
Multidrop Line
A single communications circuit that interconnects many stations, each of which contains
terminal devices. See RS485.
PACKTRACK™
PackTrack™ is a Datalogic patented parcel tracking system which improves the reading
features in omnidirectional stations. In particular, PackTrack™ manages
6-sided reading systems when it is impossible to detect the real position of the code on the
parcel, thus overcoming the need for external accessories essential in traditional tracking
systems.
Parameter
A value that you specify to a program. Typically parameters are set to configure a device to
have particular operating characteristics.
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 such as on a Multidrop line.
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.
Serial Port
An I/O port used to connect a scanner to your computer.
Signal
An impulse or fluctuating electrical quantity (i.e.: a voltage or current) the variations of which
represent changes in information.
Symbol
A combination of characters including start/stop and checksum characters, as required, that
form a complete scannable barcode.
