any one can explain how do i connect a ais rc10 to a c70 raymarine?
we need more information.
I'm not familiar with the rc10, but looking at the web page it says it does NMEA.
so the connection should be a straightfoward NMEA wiring with the out on the AIS going to the IN on the c70.
HOWEVER, many AIS recievers use a different baud rate (speed) and if that's the case you may need a multiplexor.
