Cable Shielding; Suppression Ferrites; Connections Overview; Typical Cable Routing Scenarios - Raymarine Quantum Radome Installation Instructions Manual

• Always use an RS232/NMEA converter with
optical isolation on the signal lines.
• Always make sure that PC's or other sensitive
electronic devices have a dedicated power circuit.

Cable shielding

Ensure that all data cables are properly shielded
that the cable shielding is intact (e.g. hasn't been
scraped off by being squeezed through a tight area).

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.
Cables and connections (Quantum variant with RayNet)

4.3 Connections overview

Use the following information to help you identify the
connections on your product.
Connector Connects to:
RayNet network
or device. Not
required if
connecting using
Wi-Fi.
12V / 24V power
supply.
The power and data connections are located on
the underside of the scanner unit, as shown in the
following illustration.

Typical cable routing scenarios

There are 4 typical cable routing scenarios.
Note: The routing options described and illustrated
in this section assume that a physical data
connection is used between your Radar scanner
and multifunction display (MFD). However, if the
scanner is connected to your MFD via Wi-Fi, a
physical RayNet connection is not required.
1. Cable routing for a scanner mounted on a
platform, using separate cables for the power
and data connection.
2. Cable routing for a scanner mounted on a
platform, using the combined power and data
cable from an existing Raymarine Digital Radar
scanner installation. For this, the A80308
Y-adapter accessory is required (not supplied
with the scanner).
