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.
See MAC Address.
The space between two adjacent bar code characters in a discrete 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.
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.
(Internet Protocol) The IP part of the TCP/IP communications protocol. IP implements the
network layer (layer 3) of the protocol, which contains a network address and is used to route
a message to a different network or subnetwork. IP accepts "packets" from the layer 4
transport protocol (TCP or UDP), adds its own header to it and delivers a "datagram" to the
layer 2 data link protocol. It may also break the packet into fragments to support the maximum
transmission unit (MTU) of the network.
(Internet Protocol address) The address of a computer attached to an IP network. Every client
and server station must have a unique IP address. A 32-bit address used by a computer on
a IP network. Client workstations have either a permanent address or one that is dynamically
assigned to them each session. IP addresses are written as four sets of numbers separated
by periods; for example, 204.171.64.2.
Kerberos is a network authentication protocol. It is designed to provide strong authentication
for client/server applications by using secret-key cryptography. A free implementation of this
protocol is available from the Massachusetts Institute of Technology. Kerberos is available in
many commercial products as well.
A key is the specific code used by the algorithm to encrypt or decrypt the data. Also see,
Encryption and Decrypting.
The laser is an intense light source. Light from a laser is all the same frequency, unlike the
output of an incandescent bulb. Laser light is typically coherent and has a high energy density.
A gallium-arsenide semiconductor type of laser connected to a power source to generate a
laser beam. This laser type is a compact source of coherent light.
A semiconductor diode (LED - Light Emitting Diode) used as an indicator, often in digital
displays. The semiconductor uses applied voltage to produce light of a certain frequency
determined by the semiconductor's particular chemical composition.

Spectrum24 devices, like other Ethernet devices, have unique, hardware-encoded MAC
(also called IEEE addresses). MAC addresses determine the device sending or receiving
data. The MAC address is a 48-bit number written as six hexadecimal bytes separated by
colons.
1 mil = 1 thousandth of an inch.
