Im new to all this guys but basically i want to hook my mac into my NMEA network and use it to run OPEN CPN. I have a lowrence HDS 9 GEN 2 sounder / plotter that i want to obtain the data from my and populate through Open CPN. I am told my sounder / plotter outputs NMEA0183 which is confusing as i have a NMEA backbone that the VHF connects into the lowrance unit with ????. So i thought it was a lll NMEA 2000. I am not technologically gifted and all this is very new to me guys. So if there is anyone out there that can tell me what i need to do to get all this information on my Mac to use Open CPN id greatly appreciate the help.
