Possible to output GPS data from Raymarine AIS700 using NMEA 0183?

no need to buy anything else. just feed gps from the ngw to both radios. nmea 183 is rated to feed 4 things. and only let the vhf feed the ngw.

The AIS700 NMEA connections just don’t seem fit for any purpose - are they only there for troubleshooting the unit? I note that the manual recommends that the NMEA outputs should be deselected.

You don't need a second Actisense or a multiplexer. The NMEA0183 output can simply be split and connected to multiple devices.

I have setup several AIS units to output GPS to VHF radios. It is ussually easy. I wasn't able to get the raymarine to work, and I do recall a note in the manual that GPS data will not output on the 0183 interface.

Is there a way to output GPS data from AIS700 and feed it to the seatalkNK network (to have GPS data source for Axiom 7, etc.)? Or will outputing from AIS700 NMEA0183 through adaptor to network will create signal loops for AIS and GPS data?

Yes, data loops if both NMEA2K and NMEA0183 connections are made. The answer to your initial question is ‘no’.

NMEA 0183 was designed for one to one talk. But we have tired to split a output to two inputs, and havn't seen any issue.

It actually *was* designed as a one-to-multiple signal, that is why you have not seen any issues.
