Chart Plotter installation Question

[Doods]

I have been a lucky boy at Christmas and SWMBO has given me a new Raymarine C series chart plotter / display.
I have an old Raymarine already fitted, 620, with a Raystar 112LP GPS transducer, aerial, its the E32001 seatalk version.
My question is will this be ok for the new C series or will the new version of the aerial give any benifits.

From asking a simmilar question. Apparently any GPS ariel will do.

Any GPS ariel will do but you will probably have to use the NMEA connection form the C series, as the older Seatalk wont work.

Correct me if I'm wrong but I thought that all the Raymarine "Aerials" are'nt in fact aerials. I think you will find that they are actually complete GPS units in themselves and that they feed GPS data to the plotters etc. using NMEA or praps a native interface like Seatalk.
If this is the case and I'm prety sure it is, ANY NMEA feeding "GPS Aerial" should feed the C Series. If you want quicker aquisition and possibly better accuracy, then changing the "Aerial" is all thats necessary.

I think you are right about some, I dont know if that includes the raystar 125 - or the older varients. In essence though, any GPS ariel will talk to the C series through NMEA

The Raystar125 came in either Seatalk of NMEA variants. Anyway, this one is a Seatalk one and the C series support it. The only 'advantage' of the newer Raymarine GPS antennae is that they will support SDGPS if and when the muppets that run EGNOS ever get it operational...

My last two have done both. Connnected to my C70 via NMEA as I needed the Seatalk port for something else

Thanks for the info chaps. I have had a look at the spec of the old raystar and as you all say according to Raymarine it should be ok but as Wiggo says it will not support SDGPS. I can live with that for now.
I have also dug out my old Lorance chart plotter details and have found that the antenna is a NMEA variant, which according to the spec is ok for raymarine so this may also work.
Should be at the boat tommorow so will have a go at fitting it.
Thanks for the help

I thought you could parallel wire lots of seatalk gizmos together and it all self-multiplexes when it reaches the C display. ??

[/ QUOTE ] On the subject of GPS ariels is everyone aware there is a small watch type battery in the Raymarine 125 about the size of a 1p piece. Had a problem with mine so dismantled it to find a battery. Some are hard soldered on others just a slide fit depending when they were made.

Interesting. I presume that is used to hold the last position to reduce the startup time. How did you know it needed changing, out of interest?
