Any Raymarine products featuring a 1st generation SeaTalk interface which do not additionally feature a SeaTalkng interface (ex. ST40/60+ Instrument Displays, ST6002, S3G, C70, etc.) should be interfaced to one another, in any order, using standard SeaTalk cable. SeaTalk cables can be joined using D244 SeaTalk Junction Blocks, splices, marine grade terminal strips, or R55006 SeaTalk Auxiliary Junction Boxes. SeaTalk cable is available in 15", 1m, 3m, 5m, and 9m lengths (D230, D284, D285, D286, and D287 respectively). This method of interfacing is referred to as a SeaTalk bus.

The SeaTalk bus will need to be branched or extended and connected to a D244 SeaTalk Junction Block. The SeaTalk Junction Block will in turn be connected to the yellow (SeaTalk) port of a SeaTalk to E22158 SeaTalkng Converter (updated with w/v1.21 or later SeaTalk to SeaTalkng Converter software) using the cable supplied with the SeaTalk to SeaTalkng Converter Kit. The Raystar 130/150 GPS Sensor will in turn be interfaced to one of the white SeaTalkng spur ports using the cable supplied with the GPS sensor. The SeaTalk bus will be disconnected from its present power source (note that the SeaTalk port of a C-Series Classic MFD is powered), as it will now be powered via the SeaTalkng Converter. The SeaTalkng power cable supplied with the SeaTalk to SeaTalkng Converter Kit will be interfaced to the other white SeaTalkng spur ports of the SeaTalk to SeaTalkng Converter and to a 12VDC power source. Finally, the 2 SeaTalkng Termination Plugs will need to be installed in the two blue SeaTalkng backbone ports of the SeaTalk to SeaTalkng Converter.

See diagrams below addressing how one would typically interface a Raystar 130/150 GPS Sensor to a C-Series Classic MFD. Please pay notice to ensure that the red lead of the first generation SeaTalk cable connecting the C-Series Classic MFD to the SeaTalk bus is not to be used, any exposed conductor clipped, and the lead should be insulated to prevent shorting.

NOTE: At the time that this FAQ was posted, the SeaTalk to SeaTalkng Converter's software did not support bridging of the following non-critical GPS sensor data to SeaTalk:
- Satellite Status
- Sky View
- FIX rather than SD FIX will be reported within the FIX Status field when a WAAS GPS FIX has been acquired

All other GPS data items (lat, lon, UTC Date, UTC Time, HDOP, and Mode) will be correctly reported. When determining the accuracy of the GPS position FIX, HDOP will be used. When a Raystar 130/150 GPS Sensor is installed in a location affording it an unobstructed view of the skies overhead, the Raystar 130/150 GPS Sensor will typically provide the system with a HDOP less than or equal to 1.0 (lower HDOP equates to higher accuracy).
