Digital Selective Calling (DSC)
The Ray54E 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.Wh en 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 radio. You can request an MMSI number from the same agency that issues radio or Ship Radio licences in your area. Once obtained, you can progra m the
MMSI number yourself one time only using the menu operation described in
My MMSI ID on page 72.
The Ray54E includes the following DSC features:
•Separate receiver dedicated to handling DSC Calls on channel 70
•Position Request function sends GPS position data to or receives position
data from other stations
•Phonebook for automatically making DSC calls
•Quick Save feature saves incoming DSC Calls and the caller’s associated
MMSI number directly into the phonebook
•Quick Call feature sends Individual Calls or Group Calls direct ly from
the phonebook, just like the redial function on a telephone
•Three (3) Group IDs for making DSC Calls only to st ations in your group,
such as a flotilla or fishing fleet

2.2Planning the Installation
When planning the installation of your Ray54E, consider the following
conditions to ensure dependable and trouble-free operation.
Mount the main unit to allow easy access from the location where the boat is
normally navigated.
The main unit is designed to be mounted horizontally or vertically on a flat
bulkhead. Select a location that is non-metallic, dry , protected, wellventilated, and free from high operating temperatures and excessive
vibration. Provide sufficient space behind the main unit to allow for proper
cable connections to the rear panel connectors. Locate the main unit as near
as possible to the power source yet as far apart as possible from any devices
that may cause interference such as motors, generators, and other on board
electronics. The radio should be protected from prolonged direct exposure to
rain and salt spray.
The Ray54E is not designed to be mounted in engine compartments. Do not
install the radio in a location where there may be flammable vapours (such as
in an engine room or compartment, or in a fuel tank bay), water splash or
spray from bilges or hatches, where it is at risk from physical damage from
heavy items (such as hatch covers, tool boxes, etc.), or where it might be
covered by other equipment. Locate the radio at least 1.5 met ers from the
antenna.
Safe Compass Distance is 1 meter for a common mechanical compass; other
compass types may require greater distances. T o be sure, you shoul d locate
the radio as far as possible from the compass. Test your compass to verify
proper operation while the r adio is also operating.
T ypical Mounting Methods
The Ray54E can be conveniently mounted on a chart table, bulkhead,
overhead, or any other desired location. Refer to the foll owing figure for
typical mounting methods.
Flush Mounting
In addition to the typical Mounting Methods, the Ray54E may also be flush
mounted using the optional E46034 Flush Mount Kit. Instruct ions for
installing the radio using the Flush Mount Kit are included with the kit. These
kits are available from your Raymarine dealer.
Chapter 2: Installation5
Figure 2-1: T ypical Mounting Methods
CAUTION: Make sure there are no hidden electrical wir es or other items
behind the desired location before proceeding. Check that free access
for mounting and cabling is available.
Figure 2-2: Mounting Dimensio ns
6Ray54E VHF Radio
2.3Power Connections
The red and black Power Cord provides connection to DC power . The red (+)
wire contains a 7 amp in-line fuse. It should be connected to the po sitive
terminal of the power source. The black (-) wire should be connected to the
negative (ground) of the power source. Check the polarity with a VOM
(V olt age/Ohm Meter) and reconnect observing correct polarity . If the fuse
ever needs to be replaced, be sure to use the same type and rating.
Connect the stripped wires on the Power Cord to the nearest primary source
of the boat's DC power . A typical source would be a circuit breaker on the
power panel or a fuse block near the unit. The circuit breaker or ot her in-line
fuse should be rated at 10 amps. The power cord should be long enough to
reach the DC power source. If additional wire length is required, the cable
can be extended by adding more cable as necessary . However , for power
cable runs longer than 15 feet, larger wire diameter size should be used to
prevent voltage line loss. To ensure adequate current draw to the equipment,
Raymarine recommends that you use lugs to connect the power cable to the
DC supply and that the lug connections be both cri mped and soldered. The
connection terminal should be clean, with no sign of corrosion.
After the cord is connected to power, slide the bullet conn ectors on the Power
Cord into their mates (with the same coloured wire) on the rear of the radio.
(See Fi gure 2-3 .)
The Ray54E is designed to be operated on a 12 volt (nominal) system. If
battery voltage drops below 10.5 VDC (approximately), the icon
appears on the LCD (see page 15). Di scontinue using the radio if a low
voltage condition occurs as performance would be un reliable. If voltage
exceeds 16 VDC, the message EXCESSIVE VOL TAGE appear s on the dot matrix
display and an alarm is sounded. Immediately disconnect the rad io if a high
voltage condition occurs as the unit could become damag ed.
Figure 2-3: Wiring Connections
Chapter 2: Installation7
2.4External Speaker Connections
Located just below the power cord is a cable for connection to an optional
external speaker. Connect the white(+) wire and black (–) wire to the speaker
observing polarity as it is marked on the speaker . Mate the connector with its
counterpart on the rear of the radio. (See Figure 2-3 .) If not connecting an
external speaker, please leave the dust cover on the cable connector.
2.5Grounding
While special grounding is not generally required for VHF radiotelephone
installations, it is good marine practice to properly ground all electronic
equipment to the boat’s earth ground system. The Ray54E can be connected to
ground by installing the supplied screw and lock washer in the threaded hole
labelled GND on the main unit’ s rear panel just below the antenna jack. Then
attach a wire from this screw to the nearest ship’s earth ground connection
point. The recommended wire to be used for such grounding is #10 A WG.
2.6GPS/NMEA Data
The Ray54E accepts NMEA 0183 (V1.5) data from a position determining
device (GPS) to provide the Latitude and Longitude positi on information
that is transmitted during a DSC Distress Call. When a valid NMEA signal is
detected, the GPS indicator appears on the LCD. When no valid NMEA
signal is detected, the NO GPS indicator appears.
Connect the NMEA OUT + and NMEA OUT– signals from the positioning
device to the GPS + (yellow) and GPS – (green) wires, respectively , of the
GPS cable. Mate the connector wit h its counterpart on the rear of th e radio,
aligning the arrows on the two connectors. (See Figur e 2-3 .) If not
connecting a GPS, please leave the dust cover on the cable connector.
An example of how to make the connections using a suitable connector block
is shown in the following drawing. For specific instructi ons how to connect
your particular GPS, please refer to the handbook that came with that device.
Figure 2-4: GPS Wiring
8Ray54E VHF Radio
2.7Antenna Connections
The coaxial VHF antenna cable connects to the Ray54E antenna jack on the
rear panel using a PL259 VHF type connector . The antenna cable length can
be critical to performance. If you are uncertain, contact a prof essional
installer or call Raymarine Product Support. If a longer cable length is
required, RG-8x (50 ohm) marine coaxial cable or equivalent cable can be
used for runs up to a maximum of 50 feet. If the distance required is even
greater, Raymarine recommends using low loss RG-213 or equivalent cable
for the entire run to avoid excessive losses in power output.
If the antenna RF connector is likely to be exposed to the marine
environment, a protective coating of grease (Dow Corning DC-4 or similar)
can be applied to the connector before connecti ng it to the radio. Any other
extensions or adapters in the cable run should also be pr otected by silicon
grease and then wrapped with a waterproofing tape.
Antenna Mounting Suggestions
Mounting the VHF antenna properly is very important because it will
directly affect the performance of your VHF radio. Use a VHF antenna
designed for marine vessels.
Since VHF transmission is essentially line-of-sight, mount the antenna at a
location on the vessel that is free of obstruction t o obtain maximum range.
If you must extend the length of the coaxial cable between the antenna and
the radio, use a coaxial cable designed for the least amount of power loss over
the entire cable length.
Antenna Mounting and EME Exposure
For optimal radio performance and minimal human exposure to radio
frequency electromagnetic ener gy , make sure the antenn a is:
•connected to the radio before transmitting
•properly mounted
•located where it will be away from people
•located at least 1.5 metres (5 feet) from the radio
