I have a Robertson AP200DL Sail Autopilot connected to a 12 yr old Koden GPS through a datalink plotter and it works ok but recently I decided to upgrade to Maxsea V 10. Am now ready to suicide trying to direct connect Computer USB to Robinson autopilot. I think i have configured maxsea; added NMEA output instrument to the correct USB port and set the correct language for the pilot but no joy. Would someone/anyone out there have some clues or instructions about connecting these two. I have followed the maxsea User guide to no avail. Should i connect the GPS to the USB port through a 9 pin serial adapter or can i wire directly to the USB plug? Should I wire output to the same port as GPS and sounder input or should I use a separate USB port for data out of the laptop. I have tried both with MaxSea but no luck.
