Digital radar cable extension
For longer cable runs a radar power and data digital cable extension is required.

1. Radar extension cable.
2. Radar power and data digital cable.
3. Raymarine network switch (or crossover coupler if connecting radar directly to display).
4. RayNet cable (or RayNet to SeaTalk hs cable if connecting via crossover coupler).
Note: The extension cable connects to the radar scanner.
Note: The power connection is NOT shown in the diagram. If using an Open Array scanner a VCM (Voltage Converter Module)
must be connected between the scanner and the power supply.
Digital radar cables
You will need a dedicated radar power and data digital cable and
SeaTalk
hs network cables to connect your scanner to your system.
Connection Required cable
Digital radar scanner to power supply
and Raymarine network switch. Power and data digital cable. For
longer cable runs, extensions are
available in a variety of lengths.
Raymarine network switch to
multifunction display. SeaTalk hs network cables, available in
a variety of cable lengths.
Radar power and data digital cables
These cables contain the wires for a scanner’s power and data
connections.

Sonar connection
A sonar connection is required for fishfinder applications.
There are 2 types of connection required for fishfinder applications:
• Digital Sounder Module (DSM) connection — converts the
sonar signals provided by the sonar transducer into data suitable
for a marine electronics system. The sonar variant multifunction
displays feature a built-in Digital Sounder, enabling you to connect
the display directly to a compatible sonar transducer. Non-sonar
variants require a connection to an external Raymarine DSM unit.
Internal and external Digital sounders require a connection to a
compatible sonar transducer.
• Sonar transducer connection — provides sonar signals to the
Digital Sounder Module (DSM).
