[CA] [CA11] Replace i70 with i70s?

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Srah1953,

Should the system feature a powered and properly terminated SeaTalkng / NMEA 2000 backbone to which the i70 MFID and C90W MFD are presently interfaced, then the i70S MFID may simply be connected to an unused spur socket within the backbone via an appropriate length of SeaTalkng Spur Cable. However, should an unused spur socket not be available within the backbone, then an additional spur socket may be added to the backbone to accommodate the new device.
