The ND-100 Satellite is a compact
computer intended for use in
office environment. It is small,
quiet and easy to operate. It has
a built-in floppy drive, as well
as an internal storage device (a
fixed disk). It will also normally
be equipped with a cartridge tape
drive (streamer).
Telefix, a system which permits
analysis of errors in the computer
directly from Norsk Data's Service
Center, is available.
In addition to the ND-100
Satellite, your computer system
consists of the following:
a CONSOLE TERMINAL, which is the
main terminal'of the system,
normally used by the system
supervisor
one or more USER TERMINALS, each
consisting of a KEYBOARD and a
VDU (Visual Display Unit)
a PRINTER
NOTE
The technical expressions used
in this manual are explained

You will need this manual if you
are a REGULAR USER or a SYSTEM
SUPERVISOR.
As an REGULAR USER, you are
responsible for:
copying your data files onto
floppy diskettes for safe
keeping (this is called taking
PERSONAL backup )
correcting simple errors
calling the system supervisor if
a fault occurs which you are
unable to correct
You will find all the information
needed to carry out these duties
in the chapters marked "FOR
ALL
READERS" (see table of contents)
No prior knowledge of computers is
needed to understand these
chapters.
As a SYSTEM SUPERVISOR, you have
the same duties as the regular
user, but in addition your tasks
include
:
installing the system and
getting it operational
0 creating users and allotting
them user areas on the fixed
disk
regularly copying all data files
onto a streamer tape or floppy
diskettes for safe keeping (this
is called taking SYSTEM backup)
0 carrying out preventive
maintenance on the streamer and
floppy drives
handling error situations
installing programs
Most of these points are covered
in the chapters marked "FOR THE
SYSTEM SUPERVISOR". For additional
information, consult the following
manuals

To reduce the risk of unwanted
power breaks, which might lead to
loss of data, the
ND-100 Satellite
should be given a separate power
circuit which bypasses the switch
Fl
for the office power.
HOW TO CONNECT TERMINALS AND PRINTERS
There are two types of ccnnecting
cables. CURRENT LOOP is the most
common in this system, but some
printers may require a
V24 cable.
If your system includes a printer,
find out you which type of cable
fits the socket mounted on the
printer. You will then know if it
is a
V24 or current loop printer.
The equipment is connected to the
ND-100 Satellite by the fcllowing
procedure:
Select each socket to be either
current loop or
V24 by setting
the selector switches on the
terminal interface card.

INSTALLING Starting Logging Pers.backup Sys.backup Error
Connect the console terminal to
the socket marked CONSOLE, using
a current loop cable.
In addition to the console
terminal, a total
of eight units
(terminals and printers) can be
connected.

2. STARTING THE SYSTEM (SYSTEM SUPERVI SOR)
SWITCHING ON
1) Locate the mains switch at the
back of the computer and switch
it on.
STOP START RUNNING
1000jl
LOCKED
STANDBY
Go to the front of the computer
and turn the key switch to
position ON.
CAUTION
Do not move the computer after
the key switch has been turned
ON, as this may damage the
disk.
3) Press the START button to start
the computer.
4) Wait until the word 'running'
appears on the operator panel.
Then turn the key switch to the
LOCKED position. This blocks
the operator panel, so that
nobody can use it while the
computer is running.
Norsk Data ND-30.041.1 EN

Standby batteries
CAUTION
The computer has a standby
battery which will keep the
system alive for approximately
12 minutes in case of power
failure. To prevent undesirable
discharge of this battery,
observe the following:
While the key switch is in ON
or LOCKED position, never
switch off the main switch at
the back or in any other way
disconnect the computer's
power. This would discharge
the standby battery within
12
minutes.
Always set the key switch to
position STANDBY before
switching the mains switch
off, or otherwise cutting off
the power to the computer.
NOTE
In this manual, everything
that YOU are expected to type
in from your terminal is
shown underlined. In user
names and passwords, hyphens
(-) must be used instead of
spaces between the words.
To get in touch with the
computer's operating system, you
must LOG IN.
To log in, you need a USER NAME.
The user name is the name by which
the computer knows you. Your user
name as a system supervisor is
SYSTEM.
Norsk Data ND-30.041.1 EN

Installing STARTING Logging Pers.backup Sys.backup Error
1) You may have to wait about one
minute after switching on the
computer before the consoler
terminal is ready.
2) Press the ESC key in the upper
left corner of the keyboard.
3) The word ENTER appears on the
screen. Type
SYSTEM and then
press
+J (carriage return) .
4) The word PASSWORD appears. If
HOW TO USE SINTRAN
you do not have a password yet,
simply press
A. If you know
that a password has been
programmed in.,type it, and
then press
+J.
OK is displayed on your screen.
On the next line, the sign '@I
appears. The '@' is called the
SINTRAN sign. It means that you
are in contact with SINTRAN,
which is the computer's
operating system. You can think
of SINTRAN as a 'traffic
control' system in the computer
(remember that several people
may be using the computer at
the same time, so some sort of
traffic control is needed).
You communicate with the computer
by using SINTRAN commands. There
are three important things to
remember about these commands:
They can only be typed in when
the SINTRAN SIGN
I@' or the
words 'SINTRAN command' are
displayed. This indicates that
the computer is ready to receive
a command.
As in a user name, hyphens must
be used instead of spaces
between words.
Norsk Data ND-30.041.1 EN

Installing STARTING Logging Pers.backup Sys.backup Error
The command is not carried out
until the key is pressed.
Here is
a. useful SINTRAN command
which you can try straight away.
Type WHO-IS-ON followed by
A .
This tells you who is using the
computer, and their terminal
numbers. At present, you are the
only user.
CREATING USERS
As a system supervisar, one of
your tasks is to CREATE USERS.
This simply means to 'introduce'a
person to the ND-100 Satellite, so
that the computer will 'recognize'
this person when he or she tries
to log in.
When creating a user, you must
also reserve some space for
him/her on the computer's storage
device (the fixed disk). Depending
Creating a user
on its size, the fixed disk in the
ND-100 Satellite contains
16, 22,
45 or 74Mb which must be shared
between the different users.
In this example, we assume that
you create a user with the user
name
ANNE, who needs 250 pages.
Type in the instructions as shown
to the left:
DELETING A USER
NOTE
A user cannot be deleted as
long as he or she still has
files on the disk. All files
must first be erased.

INCREASING OR REDUCING THE NUMBER OF PAGES
You can increase the number of
pages allotted to a user
by means
of the SINTRAN command GIVE-USER-
SPACE.
If there are no more pages
available, you can take unused
pages from another user with the
SINTRAN command TAKE-USER-SPACE.
STARTING THE USER ENVIRONMENT PROGRAM
USER ENVIRONMENT is a program
which makes
it very easy for
inexperienced users to start using
the
ND-100 Satellite. When logging
in, you will get a menu which
looks like this:
Norsk Data ND-30.041.1 EN

8
Installing STARTING Logging Pers.backup Sys.backup Error
You choose one item on the menu by
typing the number of the item or
moving the "inverse video cursor"
to the desired item, with the up-
arrow and down-arrow keys
( 4 and
f) and pressing the carriage
return key
( +J ) . A submenu appears
on the screen, from which further
choices can be made.
NOTE
Further on-screen information
about the menu and how to use
it can be obtained by pressing
the HELP key. Press EXIT to
get the menu back.
In some installations, the USER
ENVIRONMENT program must be
started manually when the computer
is switched on. If you want
automatic loading of USER
ENVIRONMENT, contact your
ND
representative, who will arrange
it. USER ENVIRONMENT will then be
automatically switched on when the
ND-100 Satellite is started.
Information on how to start USER
ENVIRONMENT manually can be found
on the Program Description sheet.
Although USER ENVIRONMENT is now
operating, it is still 'empty',
i.e. it does not have any users
except yourself. What you must do
now is to 'move' the users you
created earlier (page
6) into the
USER ENVIRONMENT program, so that
they can use it.
1) Log out by giving the S1NTRA.N
command LOG. Then press the ESC
-
key. You get the screen picture
shown below.
