Connecting SeaTalk1 and NMEA2000 using the SeaTalk Converter

RE: Connecting SeaTalk1 and NMEA2000 using the SeaTalk Converter
Welcome to the Raymarine Forum brewgyver,

As indicated within the FAQ found here, the SeaTalkng to NMEA 0183 data bridging features of the SeaTalk to SeaTalkng Converter are limited to bridging the data items that would typically be necessary to support the GPS data requirements of a DSC VHF radio. Accordingly, when operating in SeaTalkng to NMEA 0183 mode, the SeaTalk to SeaTalkng Converter will not supply an autopilot with navigational data required to support the autopilot's Track mode feature. As such, a SeaTalk to SeaTalkng Converter would need to be used to interface the MFD to the ST4000+, and the autopilot's SeaTalk rather than NMEA 0183 interfaced would be used. To ensure that SeaTalk bus is being powered by the SeaTalkng backbone (which the SeaTalk to SeaTalkng Converter comprises or is part of), the SeaTalk cable which is connected the ST4000+ should be cut. It's yellow and shield leads would then be sliced back together, leaving the cable red leads cut. The red leads of this cable should then be insulated to prevent shorting. This action will prevent the autopilot's SeaTalk port from supplying power to the SeaTalk bus and thereby permit the SeaTalkng backbone to supply power to the SeaTalk bus.
