I have one and as former longterm Raymarine electronics
owner I am VERY disappointed.
Missed the GPS-Receiver topic: the AIS500 comes with its own GPS-Receiver, without, no transmition
Lokk for another version of PRO-AIS on the Internet
, the software
to control/program the AIS500, Raymarines version has many restrictions, the other versions allow you much more and there is even the programming code how to erase a MMSI if you need so.
With the free versio you can switch transmit on and off, with the Raymarine
version you can only do so with an E80/E120 MFD.
I have an E120 and the Seatalk
NG is the AIS500 is useless, you MUST use the fast NMEA
connection, but I guess you know this.
The AIS500 transmits NMEA
at 4800bd too, but my unit only RMC, contrary to the manual, hence useless again as my VHF
The programmers at Raymarine obviously are not sailors any more, seems they even hate sailors, 20 years ago they had good systems nowadays it is a pain. To many buses and they do not really work together nicely, they only do somehow.
