On my quest to get the boat ready for the Clyde next year.
I have a new Garmin 276c and Raymarine DSCVHF on its way to me this week, can anyone tell me what i need to get the 2 of them linked together?
Does the lead come with the GPS or do i need to buy it seperately, is so what type of lead do i need, and where can i get it?

Cheers

Al.
 
Don't know, both items are on there way to me, so not sure whats in the boxes.
Its just we are off on hols on Friday, and would like to fit them while at the boat, and will need to get anything i need pronto!!

Ta,

Al.
 
the radio might come with a cable I was looking at buying a DSC set (silva ) and it comes with a NMEA cable, that plugs into the back of the GPS. Of course you could start down the GC1 route and install a full network for all your other toys that you will want in the future /forums/images/graemlins/smile.gif
 
Radio doesn;t come with the necessary cables unless they are extremely close together - both come with an NMEA/Power cable which have multicores - from the GPS you will need to identify (by colour) the NMEA out and then from the Raymarine the NMEA in if the sets are next to each other you might be able to join them, but more often than not they aren't!

All you need is some standard cable single core or 2core and a couple of white "chocolate block" connections or some crimp terminals. Link up and hey presto - you may need to set the GPS to output the NMEA sentance.
 
Al, you asked about this before a little while ago (here) - the 276 comes with a power/nmea lead with clearly marked tails. I interfaced mine to a Navman DSC which had a similar lead - all very easy and no extra leads required.

Cheers

So i did, i forgot about that thread, well i've taken the advice and bought the 276c.
Don't know a thing about connecting electronics together, hence this specific question.
Thanks for letting me know the 276 comes with a power/nmea lead, i hope when i'm fitting it, my neighbour at the boat will be around, as he's an electronic whizz, just need to make sure i have all the cabling he needs.

Cheers

Hi, I 've just done this. The raymarine comes with a power and nmea data lead. The Garmin doesn't. You'll need to buy the garmin power/data lead circa £15 and connect the nmea out from the GPS to NMEA in on the Raymarine. Raymarine supply neat little connectors by 3m that allow you to do this. You will also need to set the Garmin to NMEA format as it is default to Garmin host. You will also need to check that the garmin is set to 4800baud.

The Garmin doesn't.

[/ QUOTE ] how do you connect it to the boats power supply then............ /forums/images/graemlins/confused.gif

Every Garmin unit designed for fixed installation I have owned has had a combined power/data plug into it and the data leads have always been clearly labeled to!

Al - as indicated above the only possible physical issue you may have is if you are mounting them significantly apart then you might need a couple of bits of wire to 'extend' the connections. Software set up wise the key, again as indicated above, is that Garmin defaults to a Garmin message rather than the NMEA sentence you want it to output. Finally don't forget that if either unit doesn't have NMEA-ve connect to the units earth directly rather than reallying on the earth to earth connection being via the boats 'common' circuit.
 
Couple of funnies with Garmins, which may apply with yours.

(1) Check the interface is set to NMEA, not Garmin's proprietory protocol which is the default on both of mine. Set baud rate to 4800

(2) Garmin don't have separate NMEA negative leads. For example my Icom radio expected a NMEA+ and NMEA- from the GPS. The actual connections from Garmin 120 were..

Garmin NMEA Out (Blue) to Icom NMEA In+
Garmin Ground (Black) to Icom NMEA In-

Hope this helps.
 
Thanks to all for the info, I'm sure with a copy of this thread, and my neighbour at marina's experience, we will get it working. /forums/images/graemlins/wink.gif

Duncan, both items going at the helm, only a few inches apart.

Cheers

It's a portable unit so you would use the cigarette lighter option or use it's inbuilt LI battery. If it were a fixed unit it would come with the power and data cable.
 
you have and apologies - I am the one making the assumption that if Al is mounting it permenantly in the boat he will be utilising the standard (but not necessarily included with unit) power/data cable!

Clearly he will now be making sure he has one!!!!!!

Sorry
 
Ok, now you are confusing me to how its powered!!!
It will be fixed mounted in the boat, but i'm told i can remove it to take home to plot courses. Do the 12v power cables fir the boat not come as standard either??
Geez, i thought the difficult part(choosing which plotter to buy) was over!!! /forums/images/graemlins/crazy.gif

Oooops, appologies, you should have everything you need then because the 276c comes with this lot :-

Package includes:
GPSMAP 276C
Basemap below
Europe:
Atlantic Autoroute
USB-PC interface cable
Power/data cable
Marine mount
Rechargeable lithium battery pack
AC adapter
Trip & Waypoint Manager CD
Manual
Quick-start guide
 
how dare you apologise and prove yourself wrong after I went to the trouble of apologising for an incorrect assumption that was, in fact, correct all along!
