I am trying to connect a Navman 7100 dsc vhf to a Garmin 128. The Garmin manual talks about:- Blue wire (nmea out) and Brown wire(nmea in)
The Navman manual talks about:- Yellow wire (nmea in (+)) from gps, and Green wire (nmea in (-)) from gps.
Is it me? What planet are these people on?
Could someone please advise which wire to connect to which. I know it isn't rocket science, but I'm just a simple sailor. Thanks in advance
 
Chris,
GPS OUT to Radio In
There should be a Signsl Ground Black to GREEN Wire on Radio

The other NMEA OUT on Radio is to feed another listener needing NMEA feed.

Hello Chris

You can't help being dumb /forums/images/graemlins/grin.gif

It's because the Navman is talking Navman colours and Garmin use different colours. The blue from Garmin is the NMEA out so connects to the NMEA in on Navman. Similarly with the out from Nav to the in of Garmin. They presume that you will have all their kit and have a common colour scheme.

What do you expect - an industry standard /forums/images/graemlins/shocked.gif

Re: What do you expect - an industry standard

I connected the Garmin plotter to the Garmin GPS that came in the same box (!) and stupidly connected matching coloured wires. That was wrong! After I read the instructions and connected non-matching wire colours it worked fine.
 
there are at leat two dummos here then, me being the second one.

I had the same problem and was helped very effectively by Paul David at Navimo UK. Give him a call on 01489-778850. Sorry I don't have the wiring diagrams he sent me to hand.
 
OMG....

Right, here's what you actually need to do. The Garmin blue wire (NMEA+ out) connects to the Navman yellow wire. The Garmin black wire (NMEA-) connects to the Navman green wire. You'll also need to set the Garmin to output NMEA (in the Interface Setup menu, select "None/NMEA"). It's all in the manuals, which are on the manufacturers' websites.
 
Re: OMG....

Many thanks for all the replies. Just proves I'm not a
s daft as you think I am. Not one respondee actually came up with the colours I mentioned, or the names of the wires, or their polarity. It must surely be time for an industry standard here.
My Garmin manual says I have a Blue NMEA OUT cable (no mention of polarity) and a Brown NMEA IN cable (again, no polarity)
My Navman manual clearly says I have a Yellow NMEA IN(+) and a Green NMEA(-) IN Both IN, note.
Confused? I should think so.
 
Re: OMG....

The Garmin brown wire (NMEA+ in) is irrelevant, because you're not sending NMEA data in to the Garmin. All you're doing is getting NMEA position data out of the Garmin, and sending it in to the Navman radio. Follow the instructions I gave you, and it will work.
 
Re: OMG....

Another vote for pvb. Out from GPS becomes In on the radio. And you are only really interested in the +ve. The -ve are ground - some do these seperately - some just use the -ve of the power feed.

The only good news is that RS232 is supposed to be "fault tolerant" - i.e. if you get it wrong nothing should go bang - it just won't work !
 
Re: OMG....

remember too that the standard output on garmin is garmin you'll have to get into the menu to make it nmea (from memory)

Re: OMG....

Hi i had a similar situation connecting standard horizon to mtech vhf one unit said to connect 3 wires the other only 2 and then the language correlation ! just had to work through it but perseverance paid off in the end.

Why cant the industry get its act together and produce some kind of universal connection, but then that would mean lots of lost work for the technicians wouldn't it !.
