Chapter 5: Digital Select Calling (DSC)
The Digital Selective Calling (DSC) protocol is a globally applied system
used to send and receive digital calls. DSC uses a unique Maritime Mobile
Service Identity (MMSI) number to direct DSC calls directly to your radio,
much like a telephone number.When the DSC signal is received, the radio
quickly switches over to Channel 70 and performs the corresponding
operation.
Note: An MMSI number is required to operate the DSC equipment in this ra-
dio. You can program the MMSI number yourself one time only using the
Menu Operation described in this handbook. Otherwise, your Raymarine
dealer can program or change the number for you.
When a DSC call is received, the Ray54 Base Station automatically responds
based on the type of call. When receiving a DSC call from another vessel or a
coast station, an alert sounds and DSC data appears in the LCD such as time
of a call, the caller and the type and priority of a call.
DSC calls fall into four categories:
INDIVIDUAL calls are made to a specific station identified by its MMSI
number. See page 39.
GROUP calls send transmissions that are only received by radios that
share a common Group MMSI number. See page 46.
ALL SHIPS calls send out a message to all vessels within range that you
wish to send a Safety or Urgency message but the situation is not serious
enough for a Distress Call. See page 50.
DISTRESS calls send your vessels position and time information to
other ships and shore stations, along with (optionally) the nature of your
Distress situation. See page 55.
POSITION REQUEST calls enable you to request GPS position infor-
mation from any vessel for which an MMSI number is known.
DSC calls (except Distress) are designated as:
ROUTINE for normal calls
SAFETY for advisory alerts
URGENCY for assistance when life is not in immediate danger

5.2 Individual Calls
The Ray54 can make Individual Routine calls and receive Individual Safety,
Urgency and Routine calls.
Making Calls to Coast Stations
The examples in this handbook illustrate making calls to Ship Stations.
However, the procedures for making Individual Calls to a Coast Station are
different. Calls to a Ship Station require that you enter a subsequent working
channel chosen from a pre-programmed list offered to you by the Ray54.
Call Type Description
INDIVIDUAL Makes a ROUTINE DSC call to a specific station identified by its MMSI
number.
GROUP Sends transmissions that are only received by radios that share a common
Group MMSI number. Up to 3 Group MMSI numbers can be stored and
called.
ALL SHIPS Sends out a message to all ships within range that you need assistance but
the situation is not serious enough for a Distress Call. This call should only
be used if hailing for assistance on channel 16 fails. There are two types of
All Ships Calls: SAFETY for advisory alerts and URGENCY for assistance
when life is not in immediate danger.
DISTRESS Sends out the position and time information from the input NMEA data
along with your MMSI number. This digital information lets other ships
and shore stations equipped with appropriate DSC equipment know
where you are and that you are in a Distress situation.
POSITION
REQUEST
This option enables you to request GPS position information from any ves-
sel for which an MMSI number is known. You can specify the target vessel
either by selecting it from your MMSI phonebook or by manually entering
its MMSI number.
RX CALL LOG A list of all received call types (except Distress calls) by number and time of
call. The log maintains up to 20 calls; the earliest call is stored at the end of
the list. After more than 20 calls have been received, the call at the end of
the list is automatically overwritten.
An Individual Call can be placed to the selected MMSI/NAME in the log.
DISTRESS LOG Lists all stored Distress calls by number and time of call.The log maintains
up to 20 calls; the earliest call is stored at the end of the list. After more
than 20 calls have been received, the call at the end of the list is automat-
ically overwritten. An Individual call can be placed to the selected MMSI/
NAME in the log.
NOTE: Received Distress Relay calls are also stored in the Distress Log.

Calls to a Coast Station remove this step from the operating procedures: the
Coast Station controls and indicates the subsequent working channel within
its acknowledgement.
The Ray54E automatically detects the correct procedures for you based on
the type of MMSI number you enter manually or with or the phonebook. If
00 is detected as the first two characters of the MMSI, Coast Station
procedures are implemented automatically.
Transmitting an Individual Call Using the Phonebook
To call another ship or coast station, you must select the specific MMSI
number to contact and the working channel to be used for the call. The MMSI
number can be entered manually or selected from a Phonebook list of
preprogrammed numbers specified using the MENU function.

5.5 Distress Calls
For a Distress call transmission, the Ray54 takes the position and time
information from the input NMEA data along with your MMSI and converts
it into a digital packet. When transmitted, this digital information lets other
ships and shore stations equipped with appropriate DSC equipment know
where you are and that you are in a Distress situation.
Your call can specify the nature of the Distress (designated call) or not
(undesignated call). When you make a Designated Distress Call, you can
select from the following types:
UNDESIG (Undesignated)
FIRE
FLOODING
COLLISION
GROUNDING
LISTING
SINKING
