Welcome to the Raymarine Forum Kenneth,

The GyroPlus (also known as the Pathfinder Smart Heading System), cannot be installed in the manner which you have suggested. Most legacy SeaTalk devices, excluding the GyroPlus, may be interfaced to a SeaTalkng/NMEA 2000 backbone via a SeaTalk to SeaTalkng Converter. In this case it is recommended that the Gyroplus and C-Series Classic MFD be interfaced to one another via an unpowered SeaTalk bus (i.e. the red leads of the SeaTalk cables connecting the C-Series Classic MFD and GyroPlus to the SeaTalk bus should not be interfaced to the red (SeaTalk Power) terminals of the products' SeaTalk port). The GyroPlus will need to be powered via its power terminals. The SeaTalk bus will in turn be interfaced to a SeaTalk to SeaTalkng Converter which has in turn been installed as a part of the powered and properly terminated SeaTalkng/NMEA 2000 backbone. The SeaTalk bus will be powered by the SeaTalkng/NMEA 2000 backbone via the SeaTalk to SeaTalkng Converter. The NMEA 0183 10Hz heading port the GyroPlus may then be interfaced to both the NMEA 0183 input port of both the C-Series Classic MFD and E-Series Classic MFD. Linearization and alignment of the GyroPlus would continue to be performed via the C-Series Classic MFD.
