Glossary - 3
Code 3 of 9 (Code 39). A versatile and widely used alphanumeric bar code symbology with a set of 43 character types, 
including all uppercase letters, numerals from 0 to 9 and 7 special characters (“-”, “.”, “/”, “+”, “%”, “$” and space). The 
code name is derived from the fact that 3 of 9 elements representing a character are wide, while the remaining 6 are 
narrow.
Code 93. An industrial symbology compatible with Code 39 but offering a full character ASCII set and a higher coding 
density...

Glossary - 4 MC9500-K Mobile Computer User Guide
Discrete 2 of 5. A binary bar code symbology representing each character by a group of five bars, two of which are wide. 
The location of wide bars in the group determines which character is encoded; spaces are insignificant. Only numeric 
characters (0 to 9) and START/STOP characters may be encoded.
DRAM. Dynamic random access memory.
DTE. See Data Terminal Equipment.

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.
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...

K
Key. A key is the specific code used by the algorithm to encrypt or decrypt the data. Also see, Encryption and Decrypting.
L
LASER.  Light Amplification by Stimulated Emission of Radiation.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.
Laser Diode. A semiconductor type of laser connected to a power source to...

N
Nominal. The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and negative 
deviations from this value.
Nominal Size. Standard size for a bar code symbol. Most UPC/EAN codes are used over a range of magnifications (e.g., 
from 0.80 to 2.00 of nominal).
NVM. Non-Volatile Memory.
O
ODI. See Open Data-Link Interface.
Open Data-Link Interface (ODI). Novell’s driver specification for an interface between network hardware and higher-level...

Glossary - 8 MC9500-K Mobile Computer User Guide
Print Contrast Signal (PCS). Measurement of the contrast (brightness difference) between the bars and spaces of a 
symbol. A minimum PCS value is needed for a bar code symbol to be scannable. PCS = (RL - RD) / RL, where RL is 
the reflectance factor of the background and RD the reflectance factor of the dark bars.
Programming Mode. The state in which a scanner is configured for parameter values. See Scanning Mode.
Q
Quiet Zone. A clear space, containing no...

SDK. Software Development Kit
Self-Checking Code. A symbology that uses a checking algorithm to detect encoding errors within the characters of a bar 
code symbol.
Shared Key. Shared Key authentication is an algorithm where both the AP and the MU share an authentication key.
SHIP. Symbol Host Interface Program.
SID. System Identification code. An identifier issued by the FCC for each market. It is also broadcast by the cellular carriers 
to allow cellular devices to distinguish between the...

T
TCP/IP. (Transmission Control Protocol/Internet Protocol) A communications protocol used to internetwork dissimilar 
systems. This standard is the protocol of the Internet and has become the global standard for communications. TCP 
provides transport functions, which ensures that the total amount of bytes sent is received correctly at the other end. 
UDP is an alternate transport that does not guarantee delivery. It is widely used for real-time voice...

V
Visible Laser Diode (VLD). A solid state device which produces visible laser light.
W
Warm Boot. A warm boot restarts the mobile computer by closing all running programs. All data that is not saved to flash 
memory is lost.
