[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Alvin,

Please be more specific about providing a complete and detailed list of the devices (ex. ST60+ Depth, ST60+ Wind, Raystar 125, etc.) which has been interfaced to the SeaTalkng backbone via the SeaTalk to SeaTalkng Converter's yellow SeaTalk socket. Have you disconnected the SeaTalk device(s) from any power circuits which had previously supplied them with power ... the SeaTalk device(s) will instead be powered via the SeaTalkng backbone. Has the SeaTalkng backbone been properly terminated (i.e. two termination plugs have been installed within the backbone, and these termination plugs have been installed within the backbone's two end sockets.
