ST70 to SeaTalk HS Network

[Chuck - Raymarine - Moderator]

Paul,

Raymarine produced a ST70 Instrument Display and a ST70 Autopilot Control ... these items are commonly confused with one another. Within your initial question, you stated that you had a ST70 Instrument display. Per the prior response, it is not possible to interface a ST70 Multifunction Instrument Display to SeaTalkhs and it is similarly not possible to use a ST70 Multifunction Instrument Display as an autopilot control head for any type of autopilot. On the other hand a ST70 Autopilot Control Head is designed to exclusively be used with a SPX-5/10/30/SOL Autopilot Course Computer. When a SPX autopilot is installed onboard a vessel, a powered and properly terminated SeaTalkng backbone having sufficient spur sockets to accommodate the SeaTalkng devices will be installed onboard. The backbone will additionally include a SeaTalk to SeaTalkng Converter if the system features any products having a SeaTalk communications interface, but lacking a SeaTalkng communications interface. The Data Master MFD's SeaTalk2/NMEA 2000 port will be interfaced to the this backbone via an A66061 E-Series Classic MFD to SeaTalkng Spur Adapter Cable. The Data Master MFD's SeaTalk/Alarm Cable will be disconnected from the SeaTalk bus, as all communications with the SeaTalk bus will now be via the SeaTalk to SeaTalkng Converter which will be included within SeaTalkng backbone. Finally, the software within the MFDs, SeaTalk to SeaTalkng Converter, ST70 Autopilot Control Head, and SPX Autopilot Course Computer will need to be updated with the final respective software update for these products.
