Hi Fred,
Yes, the blue and brown wire currently coming out of the Garmin unit provide 
NMEA GPS position data to the the VHF (GX 2100).  That appears to be working 
adequately, it is only getting the AIS data to the Garmin that is currently the 
issue.

 Bruce — are you also feeding GPS position data from the Garmin to the GX2100?

Hi Fred,
The Garmin unit is the Echomap Plus 94 SV.  Here is the manual:

Here is the manual for the Standard Horizon GX2100:

I talked to Garmin tech support on the issue, and they indicated that if the 
blue and gray wire coming out of the Standard Horizon radio (as noted on Page 
21 of the SH manual) is connected to the Garmin unit, the DSC information would 
work (it does).  The gray and brown SH wire cannot be connected to the brown 
input wire on the Garmin simultaneously (makes sense).  If the brown SH wire is 
connected to the Garmin brown wire, the Garmin unit has to be adjusted for the 
NMEA 0183 34.8K baud rate, and will display the AIS information, but the radio 
will not get the DSC information.  

Any guidance you can provide would be greatly appreciated!

 Bruce — can you confirm the Garmin model number?  I’m not seeing anything for 
that model.
I’m not sure why you can’t have both AIS and DSC on the same feed to the 
Garmin; if I can take a look at the manual, we may be able to figure something 
out.

Hello all,
I have been exploring how to connect a Standard Horizon GX2100 to our Garmin 
Echomap Plus 84 SV to get AIS data to show up on the Garmin unit.  In short, I 
have the NMEA input and output wires connected, and in that manner, appears to 
be working well in that the VHF radio is showing GPS coordinates & such, and 
the DSC is working correctly.  

The AIS data (other commercial ships) shows up on the radio, they can be 
identified, but they don't show up on the Garmin unit.  The AIS data wire 
(brown) coming out of the Standard Horizon is for high-speed NMEA data at a 
34.8K baud rate, and per Garmin cannot be connected to the Garmin single wire 
without disabling the DSC, which is far more important.
However, if the Standard Horizon is connected to the NMEA 2000 (via Seatalk 
NG), then evidently the Garmin will show the AIS data.  

Does anyone know how to connect the Standard Horizon to the Seatalk NG system? 

I asked the question quite specifically of Standard Horizon and got the rather 
cryptic response shown below.
It's not the end of the world, but I'd like to connect it if workable.

Thanks in advance, 

Bruce Whitmore

Hello Bruce:
  
 
Thank you for contacting us with your email. The GX2100 can send out AIS data 
at 38400 on it brown output wire. So long as you have an input source on your 
SeaTalk network capable of receiving NMEA 0183 at 38400 baud rate, this should 
work without issue.
  

Best regards,

Subject: Connecting GX2100 to Seatalk NG or via NMEA 0813 to Garmin Echomap 
Plus 94SV
   
 
Hello,
   
 
I have a GX2100 that was recently sent to you to have the MMSI removed and 
re-entered.  I have also recently replaced an old Raymarine chart plotter with 
a new Garmin Echomap Plus 94SV.  It is hooked to my marine gauges via Raymarine 
Seatalk NG.  I have connected the GX2100 to the Garmin unit using the green, 
blue and gray wires, and the VHF appears to properly display the coordinates.  
However, the GPS does not have another wire connection so that it can show the 
AIS information.  Is there a way to connect the GX2100 to the Seatalk NG 
backbone in such a way that the AIS information will show up on the Garmin 
unit?  
 

Thank you for your insights, 
 
Bruce Whitmore
