EMC installation guidelines
All Raymarine equipment and accessories are designed to the best industry
standards for use in the recreational marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to
ensure that performance is not compromised. Although every effort has
been taken to ensure that they will perform under all conditions, it is
important to understand what facts could affect the operation of the
product.
The guidelines here describe the conditions for optimum EMC performance,
but it is recognized that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC
performance within the constraints imposed by any location, always ensure
the maximum separation possible between different items of electrical
equipment.
For optimum EMC performance, it is recommended wherever possible:
•
•
Raymarine equipment and cables connected to it are:
• At least 3 ft. (1m) from any other equipment transmitting or
carrying radio signals. In the case of Single Side Band (SSB) radio,
the distance should be increased to 7 ft. (2m).
• More than 7 ft. (2m) from the path of a radar beam. A radar beam
can normally be assumed to spread 20 degrees above and below
the radiating element.
The equipment is supplied from a separate battery to that used for
engine start. Voltage drops below 10.8 V, and starter motor transients,
can cause the equipment to reset. This will not damage the equipment,
but may cause the loss of some information and may change the operating mode.
•
Only Raymarine-specified cables must be used. Cutting and rejoining
these cables can compromise EMC performance.

Planing hull and some displacement hull boats adopt a higher bow angle
when the boat is at cruising speed, giving poor target detection. It may be
necessary to lower the radar beam back towards the parallel, by shimming
the rear of the radar, so that the beam points slightly down when the boat
is at rest. Refer to the diagram on page 14 for more information.
Installation
Cable requirements
You must consider the following points before installing the system cables:
•
•
•
•
•
You need to connect the scanner to the multi-function display unit and
power (and, if appropriate, via a SeaTalkhs switch).
All cables should be adequately clamped and protected from physical
damage and exposure to heat - avoid running cables through bilges or
doorways, or close to moving or hot objects.
Acute bends must be avoided. The digital cable for connecting the
Digital Radome scanner to a multi-function display and power source
has a minimum bend radius of 45mm (or diameter of 90mm).
Where a cable passes through an exposed bulkhead or deckhead, a
watertight gland or swan neck tube should be used.
Avoid cutting and rejoining cables.
Scanner cables
Running the cable to the scanner
DO NOT pull the cable through bulkheads using a cord
attached to the connector. This could damage connections.
The cable connector is at the rear of the scanner unit. If the unit is mounted
on a hollow mast, the cable may be run inside the mast and connected to
the unit. Make sure that the cable does not chafe where it enters and exits
the mast. To minimize electrical interference try to avoid running radar
cables near other onboard electrical equipment. It is also good practice to
avoid running radar cables in parallel with other antenna or power cables.
Digital cable
The digital cable, illustrated below, provides both power and SeaTalkhs
signals to the Digital Radome scanner. It is fitted with a SeaTalkhs plug and
power cores for connecting to the scanner.

To display and power
D11371_1
For Digital Radome scanners that are purchased with a cable, the length
should be sufficient to complete the cable run on most small boats. For
longer runs, and for Digital Radome scanners that are purchased without a
cable, optional cables and extension cables are available.
Optional cable lengths available are:
• Part No. A55076 - 5 m cable.
• Part No. A55077 - 10 m cable.
• Part No. A55078 - 15 m cable.
• Part No. A55079 - 25 m cable.
The following extension cables are also available:
• Part No. A92141 - 2.5 m extension cable.
• Part No. A55080 - 5 m extension cable.
• Part No. A55081 - 10 m extension cable.
For boats with 12 V DC power systems, the maximum cable length is 25 m
(including any extension). If you need to run a longer cable length with a
12v supply, please contact Raymarine technical support for further advice.
Note: Do not make your own cables for use with the Digital Radome
scanner. Only use official Raymarine cables.

Grounding the radar system
It is important that an effective radio frequency (RF) ground is connected to
the radar system.
You must ground the radar by connecting the drain wire (screen) of the
power cable to the nearest ground point of your boat’s RF ground system.
Full details can be found in the Owner’s Handbook for your multi-function
display unit.
If you need to extend the wire, the extension wire should be an 8 mm braid
or 6 mm2 (AWG 10) multi-strand cable.
If your vessel does not have an RF system, connect the drain wire to the
negative battery terminal.
Note: Use only this ground connection.
Installation
Connecting the power and digital cables
