Electrical compatibility does not confirm suitability for the hull. Check material, deadrise and mounting position in the transducer guide.

This connection applies to the exact Raymarine code with its factory cable.

The module needs a separate power supply and a compatible display through RayNet; this path describes the transducer-to-module connection.

The RV transducer retains its RealVision capabilities; it does not become RealVision Max.

All displays on the same network need the same compatible LightHouse version. LightHouse 4 and 5 must not be mixed; first-generation Axiom/Axiom+/Pro/XL remain on LightHouse 4.

The transducer connects to RVM1600, not to the display. The module requires independent power.

RVM1600 firmware now uses independent numbering from LightHouse. Check the compatible version in the peripheral update package.
