Chapter 1 INTRODUCTION
The Data Modem you have purchased represents the latest state of the art in data
communication; its comprehensive facilities provide all you will need for profes-
sional data transfer purposes.
In data modem mode, you can achieve active transfer speeds of up to 57 600 bps
and up to 14 400 bps in fax mode.
This handbook, together with the descriptive information provided with your
communications software, gives all the information you need to install and operate
the equipment.
What is a Modem?
The word “Modem” is derived from the terms “MOD-ulator” and “DE-modula-
tor”. Putting it more simply, it is a device which modulates digital information into
an analogue carrier signal (tones) and demodulates the carrier signals which it re-
ceives, changing them back into digital data. This permits the transmission of data
along wires, between data terminal equipment (computers, terminals, etc…).
About this Modem
This modem operates as a full duplex, voice-band modem, where signal transmis-
sions are made in both directions simultaneously and the analogue signals which
are transmitted are in the voice-band of the telephone network - between 300 and
3000 Hz.
Data transmission between modem and terminal unit is in serial form - in other
words, the individual data bits are sent, one after another, along a single transmis-
sion or receiving line. At this stage, a word of explanation regarding synchronous
and asynchronous data transmission. In the synchronous mode, additional syn-
chronisation signals are required, to synchronize the transmission and reception
signals. In the asynchronous mode synchronisation is by means of “start-bits” and
“stop-bits” which mark the beginning and end of each data word. The modem can
dial by itself and also react automatically to incoming calls. The information it
needs in order to dial a telephone number, together with the various configuration
commands, are provided by the respective data terminal equipment via the same
serial interface which is used to send the data. In this mode, the system operates
with the so-called “AT” command set or to V.25bis.

Installation Instructions
1. Use the interface cable supplied to connect the modem to a free COM inter-
face on the computer
2. Use the telephone cable supplied to connect the modem to a Telephone jack
3. Use the mains cable supplied to connect the modem to a power socket
(220-240 VAC)
4. When the “POWER” LED is lit, the modem is ready for operation and will
provide data communication, using the factory settings which have been in-
stalled
5. Configure the modem with the communications software or fax software to
meet your requirements
➮Voice Mode is available only with the appropriate Accessory Pack
INTRODUCTION 1-3
Basic Adjustments
To make it easier for you to use your modem, two basic settings have been made at
the factory, which are suitable for the vast majority of connection systems. These
settings can be activated with the “&F” command. In the fax mode or voice mode,
the relevant software will carry out control of modem settings for you.
•for BTX Operation (Datex-J with 2400 bps), select AT&F1 in the soft-
ware as the initialisation sequence
•For general Remote Data Transmissions select AT&F0. In this condition,
the modem will attempt to create an error-corrected connection with data
compression, depending on the capability of the other party
What the LED Indicators mean:
•POWER Modem is ready for operation
•ONLINE Modem is switched to the transmission line
•DSR Answer tone is present
•DCD Modem has recognized the carrier tone from the
remote modem
•CTS Modem is ready to transmit
•RTS Transmission request is present
•DTR Computer is ready for operation
➮Ensure that the correct COM interface is used for the software employed !
