NMEA.. Does it work ?

[Badger]

If I want the new Simrad CE 33 Colour plotter and GPS, will it work with Raymarine ST60's and ST2000 Autopilot

generic answer to the generic question you pose is 'normally yes'.
providing one unit has NWEA out, and the other NMEA in, and preferably both ports configurable they should talk happily ever after.
I was surprised how easily Lowrance mapping unit was connected to my Garmin GPS, even knowing it is getting a DGPS signal as well! Simply twisted one wire from one unit with one from the other and told one to transmit and the other receive.
Your units should prove just as easy if their specification include the capability.

I am not familiar with the quoted units but Raymarine units usually their their own proprietary bus known as Seatalk. Some will accept NMEA but will need setting up to allow NMEA.

I have the larger Simrads CA42 connected with ST60's and and a big Raymarine AP. Works fine, but there are many options. The Simrad side usually is easy as it has very flexible setup of what you want to send out on NMEA and what you want to receive. My Simrad actually has two NMEA ports, not sure about the 33.

On the Raymarine side, it depends on what instruments you have. Many don't have NMEA, but the MULTI for example has, and most AP's have it. And then those that have it have a limited list of sentences they interpret, and it's differnt from instrument to instrument.

If no instrument has NMEA or has an insufficient one, you can get a NMEA/PC interface box from Raymarine. These bridge most NMEA signals to and from the Seatalk bus. The bridge has the advantage that you can also connect the PC to the Setalk stuff as it has an additional RS232 port.

Yes.

I used to have an ST2000 tiller pilot but that was a few years ago while the producers name was Autohelm. At that time the ST2000 only understood Seatalk and needed a converter to be able to listen to NMEA.

raytheon are a law unto themselves...

i have a problem interfacing my raytheon autopilot to a garmin gps: they use different messages and the result gets garbled.

most nmea in use today are nmea 0183 but it comes in several versions. my problem is one set which puts out version 2.0 and one that listens for version 1.5 (the latest kit may use nmea 2000 which is something else)

suggest you check that the version numbers agree before spending the cash.

Best advice is to stick to Raymarine kit if you can. The Raymarine Multi does produce some NMEA sentences, but by no means all, and it does use NMEA 2. It also only accepts some sentences, not all so if you are trying to steer to a chart plotter course it may not work. There are also some differences in the way manufacturers interpret the NMEA standards.

The difference between NMEA 1.5 and 2 is that 2 has an extra digit so that the two standards are not interchangeable.
