Installing a RD418D Digital Radar Dome on a 2012 BW 280 Outrage with an existing 2012 E140W
Do I need a Seatalk Crossover coupler and what cables are needed. A 10M cable A55077 was included with the unit.

Welcome to the Raymarine Forum alxxxx,

As the Digital Radar Cable now packaged with Raymarine MFDs features a RayNet (F) plug on the MFD end of the cable, it is not necessary to install a SeaTalkhs Crossover Coupler as part of the installation. Instead, an A80272 RayNet (M) to SeaTalkhs (M) Adapter will be fitted between the Digital Radar Cable and the MFD's SeaTalkhs socket.
