Suppression Ferrites; Connections To Other Equipment; Wireless Product Location Requirements; Wireless Location Requirements - Raymarine RAY63 Installation And Operation Instruction Manual

• 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 product is supplied power from a separate battery from that used for engine start. This is
important to prevent erratic behavior and data loss which can occur if the engine start does not
have a separate battery.
• Only Raymarine® specified cables are used.
• Cables are not cut or extended, unless doing so is detailed in the installation instructions.
Note:
Where constraints on the installation prevent any of the above recommendations, always ensure
the maximum possible separation between different items of electrical equipment, to provide the
best conditions for EMC performance throughout the installation.

Suppression ferrites

• Raymarine cables may be pre-fitted or supplied with suppression ferrites. These are important for
correct EMC performance. If ferrites are supplied separately to the cables (i.e. not pre-fitted), you
must fit the supplied ferrites, using the supplied instructions.
• If a ferrite has to be removed for any purpose (e.g. installation or maintenance), it must be replaced
in the original position before the product is used.
• Use only ferrites of the correct type, supplied by Raymarine or its authorized dealers.
• Where an installation requires multiple ferrites to be added to a cable, additional cable clips should
be used to prevent stress on the connectors due to the extra weight of the cable.

Connections to other equipment

Requirement for ferrites on non-Raymarine cables.
If your product is to be connected to other equipment using a cable not supplied by Raymarine, a
suppression ferrite MUST always be attached to the end of the cable nearest to the Raymarine
product.

6.3 Wireless product location requirements

The optional wireless hub, handset and active speakers require further considerations when
selecting a mounting location

Wireless location requirements

A number of factors can influence wireless performance. It is important to ensure you test the
connection performance at the desired location before installing wireless-enabled products.
Distance
The distance between wireless products should always be kept to a minimum. Do not exceed the
maximum stated range of your wireless product (maximum range will vary for each device).
Wireless performance degrades over distance, so products farther away will receive less network
bandwidth. Products installed close to their maximum wireless range may experience slow
connection speeds, signal dropouts, or not being able to connect at all.
Line of sight
For best results the wireless product should have a clear, direct line of sight to the product it will be
connected to. Any physical obstructions can degrade or even block the wireless signal.
The construction of your vessel can also have an impact on wireless performance. For example, metal
structural bulkheads and roofing will reduce — and in certain situations — block the wireless signal.
If the wireless signal passes through a bulkhead containing power cables this can also degrade
wireless performance.
