Thanks for your reply.
I went with the same settings and connections as connecting a FCV-588 to GP-1971 and seems to work good in the garage.Have not tried on the water yet.
When doing wiring I always recommend referring to page S-1 of the manual that shows the wiring and color code. TD=Transmit data RD=Receive Data. View attachment 5689
Hi Johnny. So I have my GP1871f connected to my FCV800 via NMEA0183. And I think I did it correct. Blue wire TD to blue RD white wire TD to white RD. (Or is my wiring wrong ? When I push the Mark key is keeps saying no position data.
