Raymarine C series nmea in port.

[TSB240]

Can the eggspurts on here confirm that the Raymarine C series only allows for one baud rate input on nmea connection?


The original active gps antenna is connected via the seatalk input. Battery has been replaced but getting a fix takes forever.
I also have an AIS transceiver connected and working well on the highest baud rate connected via the nmea in port.

I have a spare nmea active antenna.

Is my only remaining option to connect this via a seatalk adaptor to the seatalk input to replace the lazy original gps antenna?

If you are sending AIS data to the plotter you can take GPS from that, as a rule.

What make/model of AIS ? Which C series ?

Hi Paul
Raymarine C80 classic plotter with last available software upgrade.
Onwa KP27A
The C80 only has the one NMEA port. I am fairly sure this can only be set up at a single baud rate for both input and output.

I have not tried disconnecting the seatalk gps from the C80 to see if it then defaults to using the nmea nav data from the Onwa.
There is no software switch on the C80 classic to select gps source unlike the wide-screen versions.

Is there any "secret"monitor screen on a C80 that shows actual nmea sentences being received?

I am beginning to think the C80 is very nearly redundant other than for very rare radar use.

I have not checked if the C80 is still talking to the ancient B and G autopilot which is still connected to the C80 nmea output! Really wouldn't miss that function as I can't remenber the last time I used it to steer to a waypoint or a route.

Looking at the manual here: file:///C:/Users/paul/Downloads/KP-25%20and%20KP-27%20Series%20ONWA%20Chartplotter%20manual.pdf

You need to enable GPS output on the Onwa, details on page 89.

Picture 13.1.1.2_1 select NMEA0183+ AIS

Picture 13.1.1.2_2 select GGA or GLL

Leave the baudrate at 38,400

Thanks will give it a try tomorrow

I am pretty sure that the C80 defaults to seatalk 1 gps if it sees a seatalk 1 gps on its network. You will have to disconnect the seatalk gps reciever before it will use the ais nmea gps data

I think you're right

Correct. That is what I found. Also, the old raymarine gps receivers suffer the date rollover problem so they cannot be relied on for data such as tides on your plotter.

Thanks to Paul and others for confirming.
Disconnected Seatalk GPS and everything is working perfectly using the Onwa as both AIS and GPS source.

Excellent, thanks for confirming
