I live in the UK and keep Tigerlily in Portugal which makes it difficult to stay on top of what mechanics and electricians are trying to say to me so can any of you help me out here.
When I bought her she was fitted with a Ramarine C70 GPS / plotter and a Standard Horizon DSC radio. I asked the electrician to make the two talk to each other so that I could use the DSC facility. He says that he doesn't know how because there are 4 ports into the C70. One NMEA, one Seatalk, one power and one DSM.
I know that DSM is Raymarine's Digital Sounder Module so it isn't that, there are no other Raymarine electronics so it can't be Seatalk, so it must be the NMEA port. However when he connects these the radio still receives no signal from the GPS.
What's also thrown me is that apparently there is no input for the GPS antenna so where does that signal enter the C70?
DSM is Raymarine's Digital Sounder Module
Any ideas?
