Connection to DTE and telephone line/set
The modem is connected to the telephone set and the line through a
standard connector.
1.4.1 Connection to DTE
The computer/terminal is connected to the modem by a standard
modem cable.
Recommendation V.24/V.28
1. Insert the 25-pin plug at the back of your modem. (Marked
DTE V.24/V.25)
2. Tighten the mounting screw on each side of the connector
shell so that it is securely attached to your modem.
3. The other end of the cable is connected to the serial port on
the data terminal or the desired communication port on the
computer.
If your equipment has more than one serial port, you must make
the right selection.
1.4.2. Connecting the modem to telephone line
Lead 1.
Where one end, with the minicontact of the modular phone cable
fits into the jack marked LINE in the modem, while the other end
fits into the wall plug.
1.4.3 Connecting a telephone to your modem
Lead 2
With miniplug at either end is connected the tastaphone and the
jack indicated PHONE on the modem.

1.5 Checking that everything is OK
Check that you have all the required parts. See that cables are
correctly connected and firmly in position.
The modem should NOT be placed near a stove or heater nor in
direct sunlight. The electronic components may be damaged if
exposed to extreme temperatures.
Thundery weather is particularly dangerous. Powerful surges can
occur over the telephone network or through the power supply. The
best protection is obtained by disconnecting the modem under such
circumstances. An alternative is to connect the modem to an
apparatus designed to hinder such surges in the telephone and
modem cables as well as in the mains supply.
1.6 The Front Panel
The figure below shows the front panel of the modem with 2*24
character LCD display for status readout/ menu guide and switches
for operation/configuration
DMM

“Read «Switches at front panel» chapter 5, for further
description.
1.7 Modem configuration
The modem has a wide range of operating modes selectable both by
internat hardware jumpers (see chapter 5) and by commands (see
chapter 3) and S-registers (see chapter 4).

is
powered
by
an
internal

supply.
Connect
the

a

outlet
and
turn
the
unit
on
by
setting
the
power
switch
on
the
rear
of
the

2.2
Selection
of
operating
mode
Setup
and
control
of
the
modem
can
be
carried
out
in
three
different
ways:
By
commands
from
an
asynchronous
DTE
connected
to
the
V.24NV.28 interface
By
V.25
bis
commands
from
a
synchronous
terminal/port
using
a
standard
V.24/V.28
interface.
By
remote
commands
entered
over
modem
connection
from
remote
modem/DTE
«
From
display/switches
on
the
front.
Selection
of
method
will
depend
on
type
of
connected
DTE
and
the
habits
of
the
operator.
Communication
programs
for
mainframes,
minis,
workstations
or
PCs
will
normally
base
their
operation
of
the
modem
on
AT
commands.
If
synchronous
data
transfer
shall
be
used,
it
will
often
be
most
practical
to
use
front
panel
operation
for
configuration
of
the
modem.
Using
an
asynchronous
terminal
or
PC
with
communication
program
the
modem
can
be
configured
from
this
and
setup
can
be
stored
in
|
the
modem
before
connection
to
the
synchronous
equipment.
For
synchronous
operation
it
is
recommended
to
configure
the
modem
for
"DUMB"
mode
(modem
will
not
accept
any
commands).
Synchronous
equipment
will
normally
send
data
continuously
and
in
some
phases
this
may
mislead
the
modem
to
try
interpreting
the
synchronous
data
as
commands.
Chapter
5
and
10
is
describing
manual
use
and
synchronous
connection.
It
is
possible
for
your
modem
to
receive
synchronous
(SDLC)
V.
25
bis
command
in

The modem is intended both for switched and leased line operation.
Chapter 11 is describing leased line operation.
"The modem is powered by power supply (16 V AC).

2.3. Connection to an electronic bulletin board
As the final point in preparation and testing of the modem, we advise
that you cali an established bulletin board. In Norway, users may call
Semaforum in Arendal/Norway. This is an electronic bulletin board
located at the offices of the development team of the product, and is
specially oriented to modem users. Here, you can obtain information
concerning the modem, the latest news regarding modems and an
opportunity to download various data programs. All users have entry
to the data base. If you have any enquiries or comments (for example
in connection with use of this modem), you may enter these into the
database.
2.3.1 Connection can be carried out by three means:
1. Manually. Dial the telephone number in the normal manner and
press the CALL menu selection switch to achieve contact.
2. Semi-automatically. This is done by entering the commands
from the keyboard on your computer or terminal.
3. Fully-automatically. Controlled by your own data
communications program, for example by selecting a
telephone number from a list.
The procedure may appear a little complicated when carrying
this out for the very first time. As soon as you set the modem to
Suit your equipment, the main task is done and the modem will
be found simple to operate.
