GENERAL DESCRIPTION
The DSC 9000 is an MF/HF DSC
Controller-Receiver which complies with the
GMDSSrequirements specifiedin SOLAS88,
chapter IV, when it is connected to a SKANTI
TRP7000orTRP8000oranothersuitableHF
transceiver.
It is designed in accordance with the
recommendations and specifications of the
IMO, ITU and CEPT for Class-A DSC
equipment in the maritime mobile MF/HF
service.
The Digital Selective Calling (DSC) system is
a world-wide system for ship-to-shore,
shore-to-ship, and ship-to-ship calling. It is an
essential element in the Global Maritime
Distress and Safety System (GMDSS) but is
also used for public correspondence with land
networks through coast stations providing this
service.
Calls may be directed to single stations, to
groups of stations or to all ships, and contain
information about the category of the call
(distress, urgency, safety, ship’s business or
routine), proposed frequency for subsequent
communication, etc. In distress calls the
distress position, nature of distress, etc. may
be included.
Visualandaudiblesignalsadvisethereceiving
party when calls are received. When contact
has been established, frequencies are
changed to the indicated working frequencies
andthecommunicationiscarriedoutasusual.
DSC 9000 MF/HF Controller-Receiver is a
compact equipment in modular design
featuring the latest SMD technology. It
consists of:
DCU 9000, DSC Control Unit, compact and
easy to use, with large 160-character backlit
LCD display with 4 lines. Splash-proof, backlit
keyboard with tactile and audible feed-back.
Up to 5 DCU 9000 sets may be connected to
the DU 9000. The units are chain connected
with a single cable.
DU 9000 DSC Unit, containing single channel
or scanning receiver, power supply module,
and the PCP module (Programmable
Communication Processor) with DSC
modulator, two DSC demodulators, and
processor for control of the DSC unit and the
communication with the DCU 9000, the HF
transceiver and other connected equipment.
The unit is fully remote controlled from the
DCU 9000 and may be installed in any
convenient, suitable place. An additional DU
9006 DSC Unit configured as a DSC watch
receiver may be connected where a second
continuous watch receiver is needed.
The DSC 9000 MF/HF Controller-Receiver
hascompletecontroloftheSKANTITRP7000
orTRP8000HFtransceiver.Thisfeaturegives
automatic transfer of the receiver and
transmitter frequencies from the DSC 9000 to
the HF transceiver. Furthermore, if an
additional DU 9006 watch receiver is not
connected, the receiver in the SKANTI TRP
7000orTRP8000maybeutilizedforscanning
of DSC calling channels while the receiver in
the DSC 9000 simultaneously maintains
distress and safety watch.
Interface(NMEA)tonavigationalequipmentis
included for automatic position updating. An
external distress button may be connected for
remoteactivationofdistresscalls,andexternal
alarmsmaybeconnectedforremoteindication
of received calls.
A serial interface for connection of a printer is
included for selectable print-out of all calls,
distress and safety calls only, transmitted and
receivedcalls,orreceived callsonlyas wellas
the possibility of printing out Short-dial list,
DSC frequency list, MMSI list, Telephone list
and configuration settings.
Received calls are stored until read-out. Up to
20 different distress calls and 20 other calls
can be contained in the store.
TheDSC9000remembersthelasttransmitted
call in each format and category for easy
repetition. Furthermore a short-dial register is
included which may contain up to 99 user
pre-programmed calls for easy recall.
When sending acknowledgements or calls in
response to a received call, relevant
information is automatically transferred from
the received call for fast and easy response.
The DSC 9000 has direct-dial facilities in
accordance with the operational procedures
specifiedforshipstationsinRecommendation
ITU-R M.1080: INTERNATIONAL MARITIME
MF/HF RADIOTELEPHONE SYSTEM WITH
AUTOMATIC FACILITIES BASED ON DSC
SIGNALLING FORMAT.
The DSC 9000 has built-in test facilities for
easy routine testing and as an aid for trouble
shooting and service.

AURAL ALARM SIGNALS
Distress Alarm: User-programmable sound indicating that a distress or urgency call
has been received. Remain activated until a key is pressed
Call alarm: User-programmable sound indicating that a call (other than distress
or urgency) has been received. Remain activated for 1/4 - 4 minutes
(programmable) or until a key is pressed or, for Direct-dial and
Selective telephony calls, the handset of the radiotelephone is lifted
off-hook.
REMOTE ALARMS
External alarm devices may be connected to DSC 9000 and configurated to be active when
- the aural distress alarm sounds, or
- the aural call alarm sounds, or
- either alarm sounds *), or
- the distress lamp is illuminated and when
the aural distress alarm sounds
*)Different on/off patterns so it is possible to distinguish between distress alarm and call alarm.
REMOTE ACTIVATION OF DISTRESS ALERT
An external push button may be connected to the equipment for remote initiation of a distress
alert.
The external push button may be combined with a lamp configurated to follow the distress lamp.
The external push button is operated in the same way as the Distress key on DCU 9000. To
initiate a distress alert press the push-button for 6 sec (until the distress lamp stops
quick-flashing and shows steady light). Then release. If not released within 5 s transmission
does not start.
KEYS AND INDICATORS OPERATION
DSC 9000 TECHNICAL MANUAL 2-5

MULTIPLE CONTROL UNITS
Up to 5 DCU 9000 control units may be connected simultaneously to a DU 9000. One of the
control units may be given priority (by configuration).
Only one control unit can be
active at a time while all others are passive . When switching on, the
control unit on which the SUPPLY ON/OFF button was pressed becomes
active . After an
interruption in external power supply all control units will be
passive .
If the active control unit is in the MAIN-MENU, STATUS or RX-CALL states or if all control units
are passive, the display of a passive control unit shows:
If the active control unit is in any other state the display of a passive control unit shows:
Only a passive control unit with higher priority can interrupt the active control unit in this case.
Only the keys , , , and are functioning on a
passive control unit.
An incoming call activates the visual and audible indicators of all control units. Light and sound
levels are induvidually adjustable.
The RX-CALL is displayed only on the active control unit.
