Raymarine AIS 700 install

[ChristianS.]

I am struggling to install an IAS 700. I have changed my MMSI number on my VHF and has ordered the IAS 700 with the same IAS number. What I have is E120 Chart Plotters. Master up and slave at the nav station. I know that I have to use the NMEA 0183 on the chart plotter, however that is already used to connect to my SIMRAD Autopilot. I have a hard wired connection on the NMEA cable between the cart plotter and the autopilot. The colors are green, white, brown and yellow. The AIS 700 has 8 wires. Hi in-, Hi in +, Hi out -,Hi out +, Lo in-. Lo in+, Lo out -, Lo out+. How do I connect these without damaging the communication between the Chart plotter and the SIMRAD auto pilot? Do I need NMEA Multiplexer. If I do what kind. Do I need to hook up both the low and the high.
Please help me with this.

I'd email Raymarine. They have been VERY responsive for us.

The e120 supports Seatalkng. Why not use that otherwise you need a spare NMEA 0183 input on the E series. Failing that a NMEA 0183 multiplexor


Make sure the E is running the latest software

I don't think the E120 supports ng. It supports Seatalk 2. But you could get a Seatalk2 to Seatalkng cable from RM.

That's the way to go.

SeaTalk2 is an enhanced replacement for SeaTalk and is a proprietary extension to NMEA 2000 and the proven CAN bus technology. It enables other Raymarine SeaTalk2
devices to talk to each other, whilst maintaining near transparent NMEA 2000 compatibility.

SeaTalk2 is in effect nmea2000

you can not connect both the ais and the pilot to the 120 at the same time. they are 2 different speeds. you would need a nmea 183 multiplexer which gets complicated.

actually only one plotter should be connected to the pilot. the 2nd one might be free for ais. I'm not sure if it would share ais to both over the network or both would need the 183 ais feeds

I don't know if the 120 can take ais via the seatalk2 port or not. if it can that will be much easier.

Thank you all for your input. I am pretty sure I need a NMEA 183 Multiplexer to make this work with the different baud speeds.

You are far better to use seatalk2 ( seatalkng) then revert to 0183
