The new i70s have only one SeaTalkng socket

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum LogoFreak,

Most currently and recently manufactured Raymarine products having SeaTalkng communications interfaces are NMEA 2000 compatible. Unlike products designed to support SeaTalkng communications protocol, which permitted up to three devices to be daisy-chained within a single spur, those designed to meet NMEA 2000 Certification requirements must installed as individual spurs to the NMEA 2000 backbone. Consequently, NMEA 2000 Certified devices feature a single NMEA 2000 spur socket. As Raymarine will be seeking NMEA 2000 Certification for the i70s and future Raymarine products supporting SeaTalkng / NMEA 2000 communications, the i70s and future Raymarine products supporting SeaTalkng / NMEA 2000 communications will feature a single SeaTalkng / NMEA 2000 spur socket. When creating a system featuring products from more than one manufacturer, the greatest level of system integration should be achieved by ensuring that each of the products to be included within the system are NMEA 2000 Certified.
