Specifications
EEPROM 
Electrically Erasable Programmable Read-Only Memory. An on-board non-volatile memory 
chip. 
Element 
The basic unit of data encoding in a 1D or 2D symbol. A single bar, space, cell, dot. 
Flash 
Non-volatile memory for storing application and configuration files. 
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. 
Image Processing 
Any form of information processing for which the input is an image and the output is for 
instance a set of features of the image. 
Image Resolution 
The number of rows and columns of pixels in an image. The total number of pixels of an 
image sensor. 
Image Sensor 
Device converting a visual image to an electric signal. It is usually an array of Charge 
Coupled Devices (CCD) or CMOS pixel sensors. 
IEC 
(International Electrotechnical Commission): Global organization that publishes international 
standards for electrical, electronic, and other technologies. 
IP Address 
The terminal’s network address. Networks use IP addresses to determine where to send 
data that is being transmitted over a network. An IP address is a 32-bit number referred to as 
a series of 8-bit numbers in decimal dot notation (e.g., 130.24.34.03). The highest 8-bit 
number you can use is 254. 
ISO 
(International Organization for Standardization): A network of the national standards 
institutes of several countries producing world-wide industrial and commercial standards. 
LED (Light Emitting Diode) 
A low power electronic light source commonly used as an indicator light. It uses less power 
than an incandescent light bulb but more than a Liquid Crystal Display (LCD). 
LED Illuminator 
LED technology used as an extended lighting source in which extra optics added to the chip 
allow it to emit a complex radiated light pattern. 
Matrix Symbologies (2D Codes) 
An arrangement of regular polygon shaped cells where the center-to-center distance of 
adjacent elements is uniform. Matrix symbols may include recognition patterns which do not 
follow the same rules as the other elements within the symbol.
