4.1 General cabling guidance

Cable types and length

It is important to use cables of the appropriate type and length.
• Unless otherwise stated only use cables supplied by Raymarine.
• Where it is necessary to use non-Raymarine cables, ensure that they are of correct quality and
gauge for their intended purpose. (e.g.: longer power cable runs may require larger wire gauges to
minimize voltage drop along the run).

Strain relief

Use adequate strain relief for cabling to ensure that connectors are protected from strain and will not
pull out under extreme sea conditions.

Cable shielding

Ensure that cable shielding is not damaged during installation and that all cables are properly
shielded.
Caution: Transducer cable
• Do NOT use the transducer cable to lift or suspend the transducer; always
support the transducer body directly during installation.
• Do NOT cut, shorten, or splice the transducer cable.
• Do NOT remove the connector.
If the cable is cut, it cannot be repaired. Cutting the cable will also void the
warranty.

4.2 Cable routing

Cable routing requirements for the transducer cable.
Important: To avoid interference, the cable must be routed as far away from VHF radio antenna
cables as possible.
Important: The transducer cable's connector is supplied with a separate locking collar assembly,
used to secure the cable firmly to a RealVision™ 3D sonar-capable device (e.g. Axiom RV
multifunction display). Ensure that you route the cable all the way to the 3D sonar-capable device
before attaching the locking collar.
• Check that the cable is long enough to reach the equipment it will be connected to. If you
are installing split-pair transducers, you must use a Y-cable (A80478) along with an extension
cable to connect the transducers to your RealVision™ 3D sonar-capable device (e.g. Axiom RV
multifunction display).
• Use grommets in any pass-through holes to prevent damage to the transducer cable.
• Secure the cable at regular intervals using cable clips (not supplied).
• Take care not to apply excessive strain to the cable where it leaves the transducer. Where possible,
allow the cable to lay naturally as it leaves the transducer, before securing it with cable clips.
• Do not bend the transducer cable beyond its minimum bend radius. This is particularly important at
the point where the cable leaves the transducer.
• Any excess cable should be coiled up at a convenient location.
RealVision™ 3D transducer extension cable
For best performance, cable runs should be kept to a minimum. However, for some installations
(including all split-pair transducer installations) it may be necessary to extend the transducer cable.
The following optional extension cables are available:
• RealVision™ transducer extension cable 3 m (9.8 ft) (part number A80475)
