Seatalkng/NMEA2000 Power

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum ledouxjj,

Q1. I have also installed a Maretron NMEA backbone system to support monitoring all the engines, weather, etc. My first question is this, I believe the Maretron cables are of heavier gauge wire and therefore a lower power loss. So should I be powering the entire NMEA2000/SeatalkNG system from the Maretron or Vice versa?
A1. Raymarine places no restriction on using SeaTalkng components to construct a SeaTalkng/NMEA 2000 backbone. Raymarine offers adapter cables to support adaptation to DeviceNet Micro-C male and female plugs/socket commonly employed in Maretron NMEA 2000 networking componets. The SeaTalkng/NMEA 2000 backbone should be powered from a single power insertion point located at the approximate mid-point of the backbone's LEN load. Raymarine MFDs are neither designed to be powered by, nor to supply power to a SeaTalkng/NMEA 2000 backbone. Raymarine MFDs are designed to be powered via the power cable supplied with the MFD.

Q2. Since Raymarine does not make a 183 to 2000 converter am I safe to assume I can use the 183 interfaces at both MFDs to connect to my ICOM VHF and SSB Radios?
A2. Your statement is not quite correct. Please click here to view a FAQ addressing this subject.
