PL3307 Decoder Integration Guide
F
Flash Disk. An additional megabyte of non-volatile memory for storing application and configuration files.
Flash Memory. Flash memory is responsible for storing the system firmware and is non-volatile. If the system power is
interrupted the data is not be lost.
FTP. See File Transfer Protocol .
H
Hard Reset. See Cold Boot .
Host Computer. A computer that serves other terminals in a network, providing such services as computation,
database access, supervisory programs and network control.
Hz. Hertz; A unit of frequency equal to one cycle per second.
I
IDE. Intelligent drive electronics. Refers to the solid-state hard drive type.
IEC. International Electrotechnical Commission. This international agency regulates laser safety by specifying various
laser operation classes based on power output during operation.
IEC60825-1 Class 1. This is the lowest power IEC laser classification. Conformity is ensured through a software
restriction of 120 seconds of laser operation within any 1000 second window and an automatic laser shutdown if the
scanner's oscillating mirror fails.
IEEE Address. See MAC Address .
Input/Output Ports. I/O ports are primarily dedicated to passing information into or out of the terminal's memory. Series
9000 mobile computers include Serial and USB ports.
Intercharacter Gap. The space between two adjacent bar code characters in a discrete code.
Interleaved 2 of 5. A binary bar code symbology representing character pairs in groups of five bars and five
interleaved spaces. Interleaving provides for greater information density. The location of wide elements
(bar/spaces) within each group determines which characters are encoded. This continuous code type uses no
intercharacter spaces. Only numeric (0 to 9) and START/STOP characters may be encoded.
Interleaved Bar Code. A bar code in which characters are paired together, using bars to represent the first character
and the intervening spaces to represent the second.
Interleaved 2 of 5. A binary bar code symbology representing character pairs in groups of five bars and five interleaved
spaces. Interleaving provides for greater information density. The location of wide elements (bar/spaces) within
each group determines which characters are encoded. This continuous code type uses no intercharacter spaces.
Only numeric (0 to 9) and START/STOP characters may be encoded.
