advice needed - GPS linking to VHF

[Andre]

I seem to recall that this subject has already been discussed and believe it was Daniel who provided an answer. Can't find the post so here is my so called problem

I am having the IC601 linked up to the Raymarine GPS Plotter 435i. My guys tell me this afternoon that both units have been fitted and are in good working order. When linked however it seems that the power signal from the GPS is too weak to activate the radio (I believe this is what they meant).

Neither of the instruction manuals say anything on this subject so tomorrow will challenge both suppliers. However I am convinced that practical knowledge of some of you bright guys out there will provide a solution as I am sure many of you may have experienced the same problem.

Am I missing any vital components which link both units?

I think you are right, I seem to remember it was Daniel. I vaguely recollect an error in the manual regarding the cable colours..but I may be wrong. I get brain fade these days...what was it you were asking?

Are you Talking about the NMEA output from your plotter? I wired my Ic601 up last night to the NMEA output from the Raymarine C80 using the cable supplied by Raymarine, I think I used the Brown and Yellow from the plotter output and soldered it onto a red jack plug an the radio....only problem is I cant remember which wire went where on the jack plug, but it worked anyway.
I will check today and post it later.

Right, The Brown Wire from the Plotter went to the Outer of the Jack Plug
Yellow goes to the Inner.

yes that is what I had in mind the NMEA. I am told this is quite low the reading shows only 0.3 volt as max peak and should be 2.3 volt

I will pass on the info as to the wires and see what can be done. My next port of call is technical chap at raymarine

will advise of final results


Andre


Just spoken to tech support and it looks like the unit is faulty and will have to be returned to Raymarine

The Icom units, whilst excellent, are a little fussy about the individual data sentences within the NMEA data string.

Specifically they need a NMEA 0183 GGA data sentence for positional data. I tried to hook one up to a Lowrance unit that was only providing a NMEA 0183 GLL data sentence, and the two would not talk. (GGA and GGL are two different formats for the positional data).

Most modern GPS should output GGA data strings, though my slightly older unit would not.

Thanks for the input. Will have to sort it out when the ribs gets over here.
Will see for myself on Sunday what the problem is

and I had enough trouble trying to work out if Input really ment to the plotter or if it ment the input to the VHF

You cover the Air fair and accom cost and I will be happy to come and sort yours for you.

Just that I suppose the VHFs come free then. Shouldn't have bother sending any money

[Daniel]

Andre it was me that offered some advise previously although it seams you may have now found the problem. If i can be of an help when the boat arrives give me a shout.

I also think this is the thread Andre was thinking of, although it only applies to Garmin GPS's and Icom VHF's.

yes we have sorted it out as the problem was the GPS, I took a third GPS over with me and that was worked very well with the IC601. Of the first two units , one just had a blank screen and with the other the NMEA signal to the VHF was just too weak . Just as well I could get a hold of a third unit in such a short time(the same model). As for the radio well the IC601 is very very good

The faulty ones will just be replaced

Jon pls give my regards to Matt

Andre

This is how the console looked during the tests. A depth sounder/fishfinder DS400X digital from Raymarine has been fitted today

the red battery isolator switch which you can just see at knee level has been replaced on both ribs cos that particular one is for single battery installation. Our ribs have twin batteries

Hi Andre,

It is looking very good. I especially like the tube colour. Console layout looks very ergonomic. Will catch up with you when you get back home.

Best wishes
Kevin.
