Chapter 5: Digital Select Calling (DSC) 37Chapter 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 vessel’s 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 danger81231_1.book Page 37 Thursday, April 22, 2004 5:21 PM
38 Ray54 VHF Radio 5.1 DSC Call FunctionCall Mode is used to initiate DSC Individual, Group, All Ships and Distress calls, to request GPS position information for another vessel and to access the Call Logs and Phonebook.The channel remains unchanged and you can perform normal TX operation. DSC mode is exited when transmitting. Press and release the CALL/MENU key while in normal operation mode to enter DSC Call Mode. The Ray54’s call type and structure are as follows:Calls the Ray54 can make: Calls the Ray54 can receive:Individual Routine Individual Safety, Urgency and RoutineGroup Routine Group RoutineAll Ships Safety and Urgency All Ships Safety, Urgency and RoutineDistress Distress, including Distress ACK and Distress RelayPosition Request81231_1.book Page 38 Thursday, April 22, 2004 5:21 PM
Chapter 5: Digital Select Calling (DSC) 39 5.2 Individual CallsThe Ray54 can make Individual Routine calls and receive Individual Safety, Urgency and Routine calls.Making Calls to Coast StationsThe 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 DescriptionINDIVIDUAL 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 REQUESTThis 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.81231_1.book Page 39 Thursday, April 22, 2004 5:21 PM
40 Ray54 VHF RadioCalls 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 PhonebookTo 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.

Chapter 5: Digital Select Calling (DSC) 555.5 Distress CallsFor 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•ADRIFT•ABANDONING (Abandoning Ship)•PIRACY•MANOVERBD (Man Overboard)81231_1.book Page 55 Thursday, April 22, 2004 5:21 PM
