IEC. International Electrotechnical Commission. This international agency regulates laser safety by specifying various laser

operation classes based on power output during operation.

IEC (825) 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

Input/Output Ports. I/O ports are primarily dedicated to passing information into or out of the device’s memory, such as

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.

I/O Ports. interface The connection between two devices, defined by common physical characteristics, signal

characteristics, and signal meanings. Types of interfaces include RS-232 and PCMCIA.

IOCTL. Input/Output Control.
