Changing from AIS receive only to transceiver

Intending to fit an AIS transceiver this winter. Existing setup is NMEA2000 B&G Vulcan 7 plotter at helm, with this fed with AIS receive only data from a B&G V50 AIS-receive VHF. Several older NMEA0183 and Seatalk I instruments and a second older plotter happily connected via a Raymarine ST/NG converter.

Will fitting a new AIS transponder (preferably one with a built-in aerial splitter) cause a conflict with the AIS receive of the B&G V50 ?? Is this a stupid question? Can AIS receive and transmit devices co-exist on the same NMEA200 network? Tried to speak to suppliers and got conflicting answers......
 
You might struggle with the baud rate which is in my experience higher on AIS transceivers.

What make of AIS transceiver are you considering ?

The Matsutec works well with NMEA 0183, but at high baud rate.
 
Shouldn't be a problem. V50 will ignore own boat as it will have same MMSI as transceiver.

The Vulcan will only use one source for AIS receive - you should be able to select which.

For NMEA0183, baud rate is same for transmit and receive devices at 38400bps but presume you'll be using NMEA2000 anyway?
 
Thanks for the confirmation that this will work. Yes the new transceiver willl use NMEA2000, and I will probably buy one with a built in aerial splitter, unless a separate one is better for any reason.
 
I fitted a separate aerial for the AIS mounted on the pushpit for several reasons, simplicity of installation, cheap wee stubby aerial and if the mast comes down, a back up aerial for the main VHF. Also one less connection in the main VHF which is a critical system in my mind.
 
the 108s has a built in splitter, I fitted it for several reasons, simplicity of installation, cheap as chips as I didn't need to buy or install anything else, if the mast comes down I will simply attach my emergency aerial and still have AIS and VHF coms.

?

I think you might have the "simplicity" backwards Chris :)

Fitting an antenna on the pushpit and running the cable through the boat doesn't seem simpler than fitting an AIS with built in splitter. One "box" to fit, connect the VHF antenna to it and a patch cable to the VHF, job done.

Look at the Emtrak range John. They make a couple of models with built in splitters and both also have built in GPS, so no external antennas or wiring. 2 x NMEA 0183, N2K, USB, and the various NMEA ports all get multiplexed.
 
I was looking at Emtraks. I know that fitting anything like a stubby aerial on the pushpit involves hours of running wires through places better accessed by a trained gibbon than an elderly human. Been there got the torn T-shirt from replacing a GPS mushroom.

I originally looked at new VHFs with built in transceivers, but the price is ridiculous and I already have an excellent 2 years old VHF.

The price is outrageous when you realise that you may also need to buy a splitter if you don't want to use independent ariels!!
