HS5 + NMEA2K +

[Chuck - Raymarine - Moderator]

Randall,

Q1. OK...I think I have it all straight. So, any issue with the AIS GPS Sensor on the NMEA 2K net interfering with data from my RS150 for my A70D? I have an older GPS receiver I can route directly to the A70D if necessary...However, is it possible to "Specify" which data is to be used?
A1. AIS receiver/transceivers will not typically transmit GPS data unless configured to do so. Accordingly, the following would be recommended should the A70D be interfaced to the system and the RS150 will be used as the system's GPS sensor:
- the internal GPS sensor within each MFD should be configured OFF
- the AIS receiver / transceiver should be configured to not transmit GPS data via its 38400 BAUD NMEA 0183 port.

Q2. Only system I have that is NMEA0183 is my VHF and I see no benefit from connecting it to the net, do you? It is an older ICOM, but should have GPS data, since it has DSC.
A2. Should
- the third party VHF radio transmit DSC position reports via its NMEA 0183 output port, and
- it be desired that the MFD automatically plot waypoints associated with such reports, and
- should you be able to procure a NMEA 0183 to NMEA 2000 data bridging device supporting NMEA 0183 DSC and DSE sentences,
then it would be recommended that the VHF radio's NMEA 0183 output port be interfaced to the system via a NMEA 0183 to NMEA 2000 data bridging device.

Q3. This would be the final configuration:

> HS5 connects the RS150 GPS Receiver, Quantum Radar, Axiom 9's x 2

> NMEA 2K has Yamaha Engine Data, EM-Track AIS Transceiver, Fuel Flow and Fuel Levels
- Bring the NMEA data into the RayTalkNG Net via the Master MFD
A3. Corrections:
- Ethernet: HS5 RayNet Network Switch will be connected to each MFD and the Quantum radome
- SeaTalkng/NMEA 2000: A powered and properly terminated SeaTalkng backbone will be installed onboard and it will be interfaced to the Data Master MFD. The engine system gateway or fuel flow monitors (but not both), AIS receiver/transceiver, Raystar 150 GPS, and tank level sensors will each be interfaced to spur sockets within the SeaTalkng / NMEA 2000 backbone.
