Garmin 740s GPS to Standard Horizon GX2200 (with AIS) connectivity

[Nehalennia]

I installed a Standard Horizon GX2200 in a local friend's 260DA, and fellow member here. He has a Garmin 740s and between the instructions Garmin and Standard Horizon have, the NMEA 0183 connections are quite confusing. I'm trying to figure it out, so if anyone has made these connections and know what goes to what, that would be great.

Maybe this will make some sense of it all?

Yes I have that in hand, but the question is the IN(-) and IN(+), OUT(-) and OUT(+) doesn't really translate to Garmin's table.

 

[dpmulvey]

What part is not matching? I was under the impression the color codes were universal.

 

[Pyrojodge]

No... this is the biggest bunch of bs... I spent three calls to standard horizon and three to garmin before my 741xs would see my ais targets.... garmin does not have a dedicated new wire for nmea0183... are you trying to hook up just the ais feature and leave the radio on its own gps? For me it was garmin blue to SH white and Garmin Brown to SH yellow for ais only... this was for the 741xs and not the 740s. The wiring for the 740s matches mine though. Hope that helps.

Todd, read this. NMEA 0183 is supposed to be differential signals but Garmin is one of the manufacturers that saves money by using ground for one of the wires. This should give you what you need to connect the Garmin NMEA 0183 wires.

We all wish.

Todd, I got mine from SH, they seemed to know about this. I have them written on the boat but will not be there until Monday.

Yeah, It would be great if there was a wiring protocol.

Jason
Thank you. I'll try that. We want the AIS and the DSC calling capability to also show shared or "FRIENDS" MMSI #s to be placed on the Garmin.

ZZ
Thanks. I'll have a closer look if Jason's method doesn't work.

MM
If you have them, that would be great to verify. Thanks!


I will be upgrading to this radio soon as well so I want to know and want it to work as above.

Todd,
I ran into the exact same problem last year when installing my Standard Horizon AIS VHF that I purchased from BOE. The Garmin 3206 0183 network wire colors did not match my manual. I spent hours trying to configure it & wasted time with Garmin tech support as the clown on the other end of the phone kept regurgitating the info from my manual. I kept telling him that I did not have those colored wires & he insisted I was wrong. I guess he could see the back of my unit better from his desk in the Midwest. I'll be following this thread & see if it sheds any light on my issue too! Good luck!!

First you need to get that radio out of your friend. i don't think the reception would be all that great. :lol:

Garmin uses (almost) the RS-232 version of the Standard Horizon connection diagram. J

But the colours should be

SH - GARMIN

Blue -> Blue [SH Input <- Garmin Output Port 1]
Gray -> Brown [SH Output -> Garmin Input Port 1]
GreenBrown -> Black [Ground]

Start with the Garmin Output and ground.

With that connected you should get GPS data showing on the radio from the Garmin

Remember to set Garmin Port 1 up to NMEA 0183 - and 38400 bps - default is NOT NMEA0183....

When that is working connect the SH Output to Garmin Input. You can also do it the other way around but I find it easier to debug one thing at the time (Input or Output)

Without my notes from install that seems exactly like what I did.

Just one caution - Garmin changed colours at some point. So I do think VERY old Garmin cables might have other colours. But the black label on the cable is usually right

Cute, thanks for the catch. I editted it.

Thank you. I will try this as well as Jason's config. We ordered a terminal block to make connection experiments easier. Once I figure it out I'll post for all to know.

Todd, my setup was for ais only

Ok. I just want to make sure the setup will allow DSC calling too, so I believe I will need to hook up additional wires?

For DSC you need the Garmin to be the talker and the VHF to be the listener. So wire Garmin NMEA out to VHF NMEA in to have the Garmin send lat/long sentences to the VHF, which it then broadcasts on a DSC call. Kaz explained how to wire that up.

Yes, that is where the SH wiring is a little buggy. I'll use a combo of all of this and figure it out and report back.


Thanks all!

Garmin's tech support got back to me. Here is their recommendation after I sent them a tech support email on Friday.

Garmin's reply
Dear Todd ,

Thank you for contacting Garmin International. Happy to help.

Based on the GX2150 Manual, it appears that your wire connections should be as follows:

Radio -----> GPS
Blue -----> Blue
Grey -----> Brown
Green -----> Black
Brown -----> Black
Yellow (AIS Out +) -----> Violet
White (AIS Out -) -----> Black

Port 1 of the Chartplotter should be set to NMEA Standard and Port 2 of the Chartplotter should be set to NMEA High Speed. Consult page 86 of the following manual on how to do this:

Please let me know if you have other questions and I'll be glad to assist.


With Best Regards,

I confirmed this setup worked perfectly yesterday. Other than the wires provided by Garmin are siamese with the power wire and Standard Horizon are very short, the installation went great. I wish Garmin separated the data wires from the power wires so they can be routed towards the VHF easier. I also wish SH would provide a longer data cable.
