Garmin gps cable fitting ?

davis · 08 November 2009, 19:00

Can anybody point me to where I can get a new connector for the coax cable fitting into the gps at the back, the signal keeps disapearing when I hit a wave.
The gps is Garmin

Is it a typical BNC antenna connector? If it is, these are widely available - try Maplin or a search on ebay.

As said, most likely a BNC jobby but if you tell us the model we can be sure.

Got a BNC connector in Maplin last week £2.50

Thanks for the replies, the model is Garmin 152 , probably a little old , but does the job

Hi

Brand new to the forum.
I have a problem in that I cannot get my garmin 152h to talk to my dsc radio. The radio is a M-Tec 500. Can anyone help. Must admit I am not educated on electronics.

welcome to Ribnet

I guess some one will know the answer, but I think it will depend on the age of both as the wether it's just a plug in and it'll work or if it needs hard wiring to sort it. my garmin 4008 needed hard wiring to the icom m505, not a big job, but much easier if you can just plug in

It'll be something like this.........

Assuming that both Garmin & Radio are powered from same battery ( common ground ), the blue cable from the Garmin( Pin 3 ) connects straight to pin1 ( the brown cable ) on your radio .

You must also set the communications on your Garmin to be using ( transmitting ) on Port 1 .

If this is not correct , I am sure someone will be along in a minute to ammend .

The hardest part may be entering your MMSI on the radio , if you haven't already done it..........

Always try the search function for these sort of questions as many of us have had to seek advice ourselves .

Connect the blue wire from the 152 to the brown wire on the M-tec 500.

Make sure the black wire on the 152 is connected to your ground, and that the red wire on the M-tec 500 is also connected to the same ground. Any problems come back

Edit: beaten to it

Also there will likely be a spare wire / pin at the back of the Garmin - Don't worry about it!

Most Plotter / GPS units will take data in as well (e.g External antenna) that's what the other wire is for.

This must be the friendliest forum out on the ether.
Thanks for the info, one question, when you mention ground, do you mean the negative connection or the black lead from the radio? As I mentioned - NO electronics/electric education.

Thanks everyone, one question, when ground is mentioned, does that mean the negative connection to the battery or the black wire from the radio? As mentioned earlier - NO electric/electronic education, educated in the age of gas.

The ground is the negative terminal of the battery. Assuming that the Garmin and the M-Tec are already powered up (ie they work), it should simply be a question of connection the blue wire on the 152 to the brown wire on the radio, then connecting the red wire from the radio to the negative terminal of the battery. This is the Garmin way, not the way all manufacturers do it.

Leave the existing power connections to the radio and the GPS alone

Yes.

Also known as earth, -ve, 0V and occasionally "sink" depending who you talk to! Almost always the black wire, but there are, as always, some exceptions....

As a general rule electricity needs an "out" and a "back". Thinkl of it a bit like a boiler &a radiator, the water has to go back to the boiler, but without the heat it left with.

The reason there is only one wire in cases like this is that the "way back" on boats is usually through the "batterey -ve" wiring, and the plotter / VHF etc uses the _ve power lead to "share" with the data return wire. (same with cars, where the entire car body is connected to the -ve of the batt), which is why you may see a lioght fitting with only one wire - the return path for the electricity is through the screw into the car body.

Hope that made sense?

Thanks all for your help. Have been in Ireland, boat left in Gower. Yes everything is now talking and my dsc radio is getting the co-ordinates for emergencies.
Must adnmit, never thought that a red wire would connect into the ground, but it does.

Boat is pretty safe, at least it has been for the past 20 years. Problem when I came home from Ireland, to find a family of blackbirds under the hood of my tractor. Will not be able to use it to launch for a couple of weeks. Last year I had wagtails, have to charge the RSPB rent.
