EMC Conformance
All Raymarine equipment and accessories are designed to the best
industry standards for use in the leisure marine environment.
The design and manufacture of Raymarine equipment and
accessories conform to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required
to ensure that performance is not compromised.

Chapter 1: Introduction
SeaTalk is the language used by Raymarine products to share
information. This is unique to Raymarine. The PC/SeaTalk/NMEA
Interface, by providing conversion between SeaTalk, RayTech PC
and NMEA 0183 data formats, allows operation with other
manufacturer's equipment and with PCs.
The PC/SeaTalk/NMEA Interface provides:
• Connection of SeaTalk to a PC running RayTech
• Conversion of NMEA 0183 data format to SeaTalk
• Conversion of SeaTalk to NMEA 0183 format
• Operation of the Raymarine Main Alarm when an alarm
condition exists on the SeaTalk bus

Chapter 2: Mounting
Select a suitable location that is:
• away from direct contact with water
• clean and grease-free
• accessible for cabling
• reasonably well protected from physical damage.
1. Once a suitable location has been found, thoroughly clea n the
surface with an alcohol based cleaner.
2. Remove the protective backing from the PC/SeaTalk/NMEA
Interface box and firmly press onto the mounting surface.

3. Alternatively, the PC/SeaTalk/NMEA Interface box may be
attached using the 2 self tapping screws provided.
4. Remove the top of the Interface box by squeezing the lid at each
end and pull away from the base.
5. Route all the necessary cables into the Interface box.
6. Connect the wires as described in Chapter 3. Also, secure cables
close to the unit.

EMC Installation Guidelines
All Raymarine equipment and accessories are designed to the best industry
standards for use in the leisure 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 factors could affect the operation of the product.
The guidelines given here describe the conditions for optimum EMC
performance, but it is recognised 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 that wherever possible:
• Raymarine equipment and cables connected to it are:
•
At least 1 m (3 ft) from any equipment transmitting or cables carrying
radio signals e.g. VHF radios, cables and antennas. In the case of SSB
radios, the distance should be increased to 2 m (7 ft).
•
More than 2 m (7 ft) 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 from that used for engine
start. Voltage drops below 10 V in the power supply to our products, 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.
• Raymarine specified cables are used at all times. Cutting and rejoining these
cables can compromise EMC performance and so must be avoided unless
doing so is detailed in the installation manual.
• If a suppression ferrite is attached to a cable, this ferrite should not be
removed. If the ferrite needs to be removed during installation it must be
reassembled in the same position.
The following illustration shows typical cable suppression ferrites fitted to
Raymarine equipment. Always use the ferrites supplied by Raymarine.
D3548-2
Connections to Other Equipment
If your Raymarine equipment is to be connected to other equipment using a
cable not supplied by Raymarine, a suppression ferrite MUST always be fitted
to the cable close to the Raymarine unit.
EMC Conformance
Always check the installation before going to sea to make sure that it is not
affected by radio transmissions, engine starting etc.

3.2 NMEA Input
The PC/SeaTalk/NMEA Interface can also be used to convert NMEA
0183 data to SeaTalk. NMEA 0183 data is also re-transmitted on
NMEA "OUT" in response to NMEA "IN". This allows non-SeaTalk
equipment to be connected directly to the SeaTalk bus.
Note: Data will not be transmitted to SeaTalk if it is already on
present on the SeaTalk bus.

3.3 Main Alarm
The PC/SeaTalk/NMEA Interface can be used to drive the
Raymarine Main Alarm (Cat No Z035). This alarm will sound as
soon as one of the following alarms is present on the SeaTalk bus:
• Deep Depth
• Shallow Depth
• Autopilot off course
• Watch alarm*
• Wind shift*
• Low battery*
• Large Cross Track Error*
• No NMEA data*
• NMEA Data error*
• No autopilot Main power
• No autopilot actuator (Drive stopped)*
• Radar Guard Zone Alarm
• Stern drive auto release
• Waypoint advance*
• Wind alarm
*The Main Alarm will sound 30 seconds after the instrument alarm.
This allows the alarm condition to be cancelled and, therefore,
avoiding sounding of the main alarm.

Servicing and Safety
• Raymarine equipment should be serviced only by authorised Raymarine
service technicians. They will ensure that service procedures and
replacement parts used will not affect performance. There are no user
serviceable parts in any Raymarine product.
• Some products generate high voltages, so never handle the cables/
connectors when power is being supplied to the equipment.
• When powered up, all electrical equipment produces electromagnetic fields.
These can cause adjacent pieces of electrical equipment to interact with one
another, with a consequent adverse effect on operation. In order to minimise
these effects and enable you to get the best possible performance from your
Raymarine equipment, guidelines are given in the installation instructions, to
enable you to ensure minimum interaction between different items of
equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC).
• Always report any EMC-related problem to your nearest Raymarine dealer.
We use such information to improve our quality standards.
• In some installations, it may not be possible to prevent the equipment from
being affected by external influences. In general this will not damage the
equipment but it can lead to spurious resetting action, or momentarily may
result in faulty operation.
