NMEA 0183 to 2000 Conversion & Axiom

[jkspain]

RESPONSE:
My Q1 was ambiguous, my apologies. My intent is to take the NMEA 0183 muxed output and port it to the NMEA 2000 bus via the NGW-1. This is in preparation for some future upgrades (AXIOM sonar is one such upgrade). I will disconnect the NMEA 0183 input to the E120 so there is only one source of data and it is the NMEA 2000 bus.

Regarding the heading sensor, I have configured the MUX to block the heading input from the autopilot so there is only one heading message on the NMEA 0183 bus. The weather station is from Maretron and does not have a GPS.

Also, I just noticed the AIS-650 has a SeaTalk NG connection so I am planning to get the correct cable to connect it to the NMEA 2000 bus and disconnect the NMEA 0183 interface to Display #2.

In addition, I was wrong about the GPS data. the GPS receiver is the Raystar and interfaces directly to the E120 master via a separate connection. I have also made a parallel connection to the AIS-650 but not sure that is necessary.

Overall, the system has been running as described for several years.
