GP1971f to FCV-800

I have these 2 units installed on my boat.
What NMEA1083 connections and settings do I need for them to talk to each other ?

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.

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.
