Daisy Chaining

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum mlpayne,

Up to three devices were permitted to be daisy chained together within a SeaTalkng spur. The total length of spur cable used to create the SeaTalkng spur was not exceed 6m. Such daisy chains required that devices within the middle of a daisy chain each have two SeaTalkng spur sockets. Raymarine's i50, i60, i70, p70, and p70R devices each had two SeaTalkng spur sockets to support such daisy chains. However, the NMEA 2000 standard does not permit such daisy chains. With the understanding that Raymarine is seeking NMEA 2000 Certification for its latest generation of products, the i70s, p70s, and p70Rs which have been designed to replace the i70, p70s, and p70Rs respectively feature only one SeaTalkng spur socket. Similarly, Raymarine MFDs, EV-1/2 Sensor Cores, and Evolution ACUs feature only one SeaTalkng spur socket.
