Looking for an AIS Receiver to Hookup to a Raymarine C120W

Our Merdian 490 PH has a 2007 Raymarine 120W Chartplotter and was wondering if anyone can recommend a make/model of AIS Receiver that might be the most compatible with the C120W? Also, would I hook up the AIS to a wire on the chartplotter display harness, or do I need to look for a black box somewhere under the flybridge helm or the pilothouse helm? My only VHF is located on the flybridge.
Thanks for any help!!

As the C120W appears to be a nmea 0183 network device, you will need an AIS with a 0183 output such as the Garmin AIS 600. What is not clear to me is if you can program preferences through a non garmin plotter. The AIS 600 is essentially a black box.

The other option is to add a full function AIS transponder with a nmea 0183 output to go into your C120W. It appears the Icom MA-500TR will do that. My only minor dislike of Icom in general is there instruction material can be confusing. The online manual indicates a nmea output without specifically listing it as a nmea 0183. So, if your interested, you should call Icom to confirm that it's compatible with the C120W.

Brain Fart. I have the Simrad AI50 on my charter boat. It's a stand alone transponder with nmea 0183 & 2000 outputs. Mine isn't networked with my plotters as they're too old. Forgot it has nmea outputs. This unit works very well.


I'm tired of fast moves, I've got a slow groove, on my mind.....

The C120W should have a SeaTalkNG connection on the back which is essentially NMEA 2000 with a proprietary Raymarine connector From a networking standpoint, that is the easiest way to go. That opens up other choices. Milltech Marine (Welcome to Milltech Marine - your AIS experts) has a good selection of AIS receivers and transponders with different network interfaces.

Em-trak B will give you both transmit and receive capability for a great price (around $400 + dedicated antenna).

Standard Horizon's GX series radios offer NMEA 0183 AIS output for about the same price as above.
