Configuration

The way a system is set up, or the assortment of com-
ponents that make up the system. Configuration can
refer to either hardware or software, or the combina-
tion of both.

Contrast

display to the dark state of the display.

Controller

The micro-controller or PC used to control the Matrix
Orbital display unit

DB-9

The designation of a connector used in the RS-232 in-
terface: 9 pin connector

Firmware

Software (programs or data) that has been written onto
read-only memory (ROM). Firmware is a combina-
tion of software and hardware. ROMs, PROMs and
EPROMs and flash EEPROMs that have data or pro-

tion of typeface and other qualities, such as size, pitch,
and spacing.

Font Metric

gins and spacing between characters and lines.

Hexadecimal

Refers to the base-16 number system, which consists
of 16 unique symbols: the numbers 0 to 9 and the let-
ters A to F. For example, the decimal number 15 is
represented as F in the hexadecimal numbering sys-
tem. The hexadecimal system is useful because it can
represent every byte (8 bits) as two consecutive hex-
adecimal digits. It is easier for humans to read hex-
adecimal numbers than binary numbers.

Short for Inter-IC, a type of bus designed by Phillip’s
Semiconductors in the early 1980s, which is used to
connect integrated circuits (I

Cs). I

C is a multi-

master bus, which means that multiple chips can be
connected to the same bus and each one can act as a
master by initiating a data transfer.
