Chapter 1. Introducing the IBM 5531 Industrial Computer
This chapter describes the hardware for the IBM 5531 Industrial Computer. Illustrations
identify power controls and power connectors as well as other parts
of the hardware. Familiarize
yourself with the parts identified in each illustration. Throughout the book,
we refer to these
parts.
The basic IBM
5531 Industrial Computer consists of a system unit and a keyboard. The system
unit contains a dual-sided diskette drive, a Diskette Drive Adapter, a Combination Adapter,
128KB
or 256KB of memory, and additional expansion slots. Your system may include a fixed
disk drive, a Color/Graphics Monitor Adapter, or other options
and adapters.
When reading this book, disregard any reference to options
or adapters that are not a part of
your system.
The keyboard, which
is used to send data to the system, attaches to the system unit with a 2-meter
(6-foot) coiled cable. The keyboard consists
of three sections: the typewriter keys, the numeric
keypad,
and the function keys.

A typical IBM Industrial Computer system consists of a system unit, a keyboard, and a
display. The display may be an IBM Industrial Display, or it may be a non-IBM display. The
examples used in this book show an IBM Industrial Display.

System Unit
The most important part of the IBM 5531 Industrial Computer is the system unit. The system
unit controls the operation
of your system. It accomplishes this through sets of instructions
called programs.
Many
of the programs for the 5531 are written in IBM BASIC, a programming language that is
already installed in your system. You can also use several other IBM-supported programming
languages
to write your own programs. You should have an understanding of fundamental
programming concepts
if you intend to write programs. Various program packages available
from your industrial dealer will also help you meet a variety
of business and personal needs.
The system unit stores
data on either a fixed disk drive or on the diskettes that are used in the
diskette drive. The system unit allows you to retrieve
data stored on a fixed disk or on a
diskette. The set
of programs that controls such operations is known as an operatingsystem, an
example of which is the IBM Disk Operating System (DOS). The reference manuals IBM Disk
Operating System (DOS)
and IBM BASIC describe the commands that allow you to store or
retrieve information.
If you choose to write your own operating system, refer to the IBM 5531
Industrial Computer Technical Reference.
The system unit contains at least one diskette drive (referred to as drive A), a Diskette Drive
Adapter,
and a CombinationAdapter.
The Diskette Drive Adapter allows you to use the dual-sided diskette drive
that is installed in the
system unit.
The Combination Adapter allows you to use asynchronous communications
and/or attach a
printer to the system unit. This adapter comes configured for primary communications
operation
and RS-232C asynchronous communications. If you use any other type of
communications, you must have the appropriate communications adapter installed. For
information on available communications options, see your place of purchase.
For a listing of options or adapters, refer to "Options or Adapters for the IBM 5531 Industrial
Computer" near the end
of this chapter.

The typewriter keys function as those on a standard typewriter. However, some keys perform
special functions. The functions
of these keys are described in the following table.
Kev
DescriQtion
Caps Lock Caps Lock,
when pressed once, locks the characters A through Z in
the uppercase position. To shift to lowercase characters while
Caps Lock is on, press the Shift key. To return to lowercase, press
the Caps Lock key again.
Enter The
function of the Enter key is defined by the programming
J language
or application you are using. Refer to the appropriate
manual for information on the function of the Enter key.
PrtSc*
This key works only if you have a printer. Pressing the PrtSc (Print
Screen) key together with the Shift key prints a copy of whatever is
displayed on the screen. If the information on the screen consists
of alphanumeric characters, as in a program listing, that
information is printed. If the information on the screen consists of
graphics characters, it can be reproduced only by a printer that
supports graphics printing.

Key Description
Backspace Backspace moves the cursor one space to the left, erasing the
+-
existing character.
Space bar The Space bar moves the cursor to the right.
Any character the
cursor moves over is replaced with a blank.
Alt Alt (Alternate) makes it easy for you to type BASIC statement
keywords. When you press Alt together with any alphabetic key (A
through Zl. the BASIC keyword is entered. You can use Alt with
Ctrl (Control) and Del (delete); see "Special Key Combination" at
the end of the keyboard section. You can also use Alt together
with any of the keys on the numeric keypad to enter ASCII codes.
Refer
to IBM Personal Computer BASIC for more information on
the Alt key.
Ctrl Ctrl (Control) performs a variety of functions. These functions are
described
in the manual that came with your operating system or
application program. You can use Ctrl together with Alt (Alternate)
and Del (Delete); see
"Special Key Combination" at the end of the
keyboard section.
Esc Refer
to the manual that came with your operating system or
application program for information on the function of the Esc
(Escape) key.
Tab Tab moves
the cursor to the next tab stop. Refer to the manual
~
that came with your operating system or application" program for
-.j
information on how tab stops are defined.
Shift
The keyboard has two shift keys. Pressing either of these keys
1S
changes the alphabetic keys to the uppercase state. Then, when
you press the alphabetic keys, the characters appear as capital
letters.

Function Keys
The function keys (Fl through FlO) are always under program control. Refer to the manual that
came with your operating system or application program for information on the use of the
function keys.
Special Key Combination
The Alt (Alternate), Ctrl (Control), and Del (Delete) keys can be pressed simultaneously to
perform a system reset. All three keys must be pressed at the same time. Doing a system reset
with these keys
is faster than setting the system unit's Power switch to Off and then to On again
when
you wish to start over (insert a new program and so on).
