Garmin Echo 94 SV to NMEA-0183 Autopilot

Postby ferdinando » Thu Apr 26, 2018 5:16 pm

I have the older Raymarine S-1000 Autopilot which is working perfectly and uses the older NMEA-0183 system which is connected to my Standard Horizon C 300 GPS which is also NMEA-0183.

I want to upgrade my chart plotter with a Garmin Echo 94 SV which is NMEA-2000. What do I need to hook up the older autopilot NMEA-0183 to the new NMEA-2000 Garmin?

I have read that there are converters out there, but some have to be programmed to the specific device.

Any help is greatly appreciated!

Thanks

Fred

Are you certain that the Garmin EchoMap 94 does not have NMEA-0183?

I believe the EchoMap 90 series has NMEA-0183. See

Jim, I am not sure about this device having [NMEA-1083], as I have installed a [NMEA-2000 network] on my boat I am purchasing this unit to make the most of my system including the gauge display.

I will investigate a little more to ck out if this Garmin has [NMEA-0183].

Thks,

Fred

Garmin seems to think the EchoMap 90 series has NMEA-0183.

For help in making NMEA-0183 connections, see my article

NMEA-0183 Interface Data Collection
viewtopic.php?f=9&t=816

There is an entry in the data collection for Garmin 90-series. See

GARMIN echoMAP 40/60 70/90, echoMap CHIRP 70/90 Series

Jim

I just rcvd my Garmin EchoMAP Plus 94 SV. You were correct that is has both NMEA 0183 and Nmea 2000. I will have to connect the NMEA 0183 to my Raymarine Autopilot S-1000. The EchoMAP has the N-83 connections bundled together with the power plug which contains the black wire for ground and the red for power. The N-83 connections are Brown for Rx (in) and Blue for Tx (out). Besides the Autopilot I also have an older Standard Horizon VHF which is N-0183 also.

My question is if my current N-2000 cables are connected to power already do I still have to connect my EchoMAP to a power source also? I kind of understand from what I read that only one power source is needed. I just want to be sure so as not to screw up this new GPS.

Thks........

Network power for a node on the network is limited. Most devices that have any sort of display, controls, interfaces, and so on will need to be powered. Generally if a device has power connections, it needs to be powered by those connections.
