Chapter 5: Digital Selective Calling (DSC)

The Ray218/Ray55 includes equipment for Class "D" Digital Selective Calling
(DSC). 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.
An MMSI number is required to operate the DSC equipment in this radio. You can
Note:
obtain an MMSI from BoatUS (www.boatus.com). Once obtained, you can program the
MMSI number yourself one time only using the operation described in "My MMSI ID" on
page 94. Otherwise, your Raymarine dealer can program or change the number for you.
The Ray218/Ray55 includes a separate dedicated receiver just for DSC
communications on channel 70. When a DSC call is received, the radio
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.
