[CA] NEMA 2000 with ST60 and ST4000+

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Greg,

Unfortunately, we don't have a diagram specifically addressing this application. With regard to interfacing an Axiom MFD to the ST60 (speed/depth) and ST4000+, Raymarine offers the SeaTalk to SeaTalkng Converter Kit to address doing so. The SeaTalk to SeaTalkng Converter will form part of a powered and properly terminated SeaTalkng / NMEA 2000 backbone. The MFD will be interfaced to one of the spur sockets of the ST-STng Converter. The unpowered SeaTalk bus to which the ST60 (speed/depth) and ST4000+ have been interfaced will in turn be interfaced to the SeaTalk (yellow) socket of the SeaTalk to SeaTalkng Converter. As the ST4000+ features powered SeaTalk sockets, the SeaTalk cable which is interfacing it to the SeaTalk bus will need to be cut and then only its yellow and shield leads will be spliced back together. Its red leads will not be spliced back together and will be insulated to prevent shorting. The power cable supplied with the ST-STng Converter will be interfaced to a switched 12VDC power circuit. Finally, you will need to add an additional spur socket to accommodate interfacing the remaining NMEA 2000 device. Please click here to view a FAQ addressing this subject. Should your NMEA 2000 device feature a DeviceNet (M) plug, then please click here to view a FAQ addressing how it may be interfaced to a spur socket within the backbone.
