Raymarine EV-100 Auto Pilot ; SeaTalk NG

Postby ferdinando » Fri Sep 18, 2020 5:46 pm

My nine-year-old Raymarine S-1000 Autopilot looks like it passed away yesterday when I took the boat out for a spin. The autopilot would engage but it just would not follow a straight course. Due to its age I have decided to replace this unit with the new Raymarine EV-100.

While looking over the manual I see that it mentions that the unit must be connected to a SeaTalkNG system that supposedly is compatible with the standard NMEA-2000 but with different connectors.

Are SeaTalkNG and NMEA-2000 compatible other than the connectors?

I have a Garmin 94sv chart plotter. I was told that the Garmin autopilot was not good at slow trolling speeds. That is why I am interested in the Raymarine.

Thanks,

Fred

I believe that SeaTalkNG (for Next Generation) is the same as NMEA-2000, and SeaTalkNG is just the Raymarine branding. The wiring appliances and connectors are different physically but are the same electrically.

If a boat already has a NMEA-2000 network installed using the very common DeviceNET Micro connectors, to connect a device to a DeviceNET network that has a SeaTalkNG connector special drop cable or a standard drop cable and adaptor will be needed. The cable will need a SeaTalkNG connector at the device end and a DeviceNET Micro connector at the network end. Raymarine makes such a cable. Here is a vendor's webpage showing the cable:

The connectors used by Raymarine are smaller in diameter. That can be an advantage if a cable has to pass through a bulkhead. The hole can be smaller.

Does the Raymarine EV-100 auto pilot include its own, dedicated, control head for operating the system?

Does the Raymarine EV-100 auto pilot include its own sensor to detect vessel heading?

Jim: from what I read, yes to both questions.

I saw a complete installation done on You Tube, both wiring and mechanical. The installer even had an up-to-date Garmin chart plotter on his boat; he did not even once mention a connection between the Garmin and EV-100.

From what I saw the SeaTalk was just connected to 12-Volt power, and then all connections went into the (what I would say was) theSeaTalk backbone and then into the EV-100.

But I would rather have [the EV-100] connected to my NNEA-2000 system nx have a direct link between the chart plotter and auto pilot.

I would follow the advice from RAYMARINE regarding installation and interconnection with other devices. RAYMARINE also has their own support forum. You can interact with RAYMARINE support specialists there.

SeaTalk - N2000

Postby ferdinando » Fri Oct 02, 2020 3:58 pm

I have now installed my EV-100 Auto Pilot. Based on Jim's info I purchased the cable where I can hook up the AP SeaTalk to my N-2000 Garmin Chartplotter.

I am not 100% sure but I think I read somewhere that I can't have both backbones SeaTalk & N-2000 hooked up to 12V power at the same time, it's either one or the other. Can someone confirm or debunk this.

Thanks,

Fred

There is no reason to have two networks. You just need one network. That some devices have a different connector does not mean you need two separate networks.
