NMEA 2000 TO 0183 cables

[aliddell]

I am trying to connect a Garmin 541S GPS to my Raymarine ST4000 Plus autopilot. The GPS has a NMEA 2000 out and the A/P has NMEA 0183 in terminals. Checking the internet I found cables that look like they will convert one to another. One I am considering is the Actisense NGW-1-ISO 2000. Do you think that the connectors will match and would this be all I have to do?

Thanks, Andy

The 541S has a NMEA0183 port why not use it.

My manual says it is a NMEA 2000 port and it has a five prong connector whereas the autopilot had two terminals labeled NMEA 0183. Doesn't look like it will work without some sort of adapter.

Garmin black to RM NMEA IN -
Garmin blue to RM NMEA IN +

Do you have to take the Garmin case apart to find black and blue? All I see on the back are the five prongs; no colors.

No, I looked up the manual on the Garmin website.

Look at page 9 of the installation manual (http://static.garmincdn.com/pumac/GP...es_INST_EN.pdf) and the back of your unit. There should be three connectors. The largest one is the wiring harness (aka power and NMEA 0183).
In fact, GPSMAP 541 has two NMEA 0183 ports.

Be aware that with the Actisense converter you would need to setup a proper powered NMEA 2000 backbone with two Ts, two terminators and a cable for the Garmin to the backbone T. You also need to make sure the NMEA0183 sequences from the ST4000 are supported by the converter.

A much simpler route is using the NMEA 0183 connection as others have suggested.

On the back of the 541. There is the big multi pole power connector with a lead that has many wires. Some of these are feeding power to the 541 so you must have it

The NMEA 0183 wires are on that big " power lead "
