Is it possible to use all three NMEA ports
on ACC1 cable of the Standard Horizon CPN700i for input?
In other words I would like to provide DSC
information on port 1, FF525 fish
finder information on port 2, and AIS
information on port 3. The DSC
information are coming from the Standard Horizon GX2200 VHF radio
Pin 8, Port 3 is really the question. As port 3 is only showing output, can I get either AIS or DSC to come in to port 3? This would save running an extra cable to ACC2.
According to the manual.
Pin 1 Black - Ground
Pin 2 Red - Battery
Pin 3 Green - Common (ground for NMEA
Pin 4 Blue - Port 1 input
Pin 5 Brown - Port 1 output
Pin 6 Grey - Port 2 input
Pin 7 White - Port 2 output
Pin 8 Yellow - Port 3 output
