Light Emitting Diode. See LED .
Liquid Crystal Display (LCD). A display that uses liquid crystal sealed between two glass plates. The crystals
are excited by precise electrical charges, causing them to reflect light outside according to their bias. They
use little electricity and react relatively quickly. They require external light to reflect their information to the
user.
M
MAC Address (also called IEEE Address). 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.
MC. Mobile Computer.
MDN. Mobile Directory Number. The directory listing telephone number that is dialed (generally using POTS) to
reach a mobile unit. The MDN is usually associated with a MIN in a cellular telephone -- in the US and
Canada, the MDN and MIN are the same value for voice cellular users. International roaming considerations
often result in the MDN being different from the MIN.
MIL. 1 mil = 1 thousandth of an inch.
MIN. Mobile Identification Number. The unique account number associated with a cellular device. It is broadcast
by the cellular device when accessing the cellular system.
Misread (Misdecode). A condition which occurs when the data output of a reader or interface controller does
not agree with the data encoded within a bar code symbol.
Mobile Computer. In this text, mobile computer refers to the Symbol Series 9000 wireless
portable computer.
It
can be set up to run as a stand-alone device, or it can be set up to communicate with a network, using
wireless radio technology.
N
NetBeui. A non-routable LAN protocol that is an extension to NetBIOS. Used for IBM’s OS/2-based LAN
Manager and Microsoft’s LAN Manager and Windows for Workgroups.
NetID. For mobile computers using Spectrum24 radios with the Spring protocol, a NetID allows facilities to limit
which Access Points a mobile computer can communicate with. It is set on the Network tab of the Control
Panel. The mobile computer can only communicate with Spectrum24 Access Points that have matching
NetIDs. Also see
ESS_ID .
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).
