Unhappy Wiring of the Autohelm ST 50 compass

New problem
I am trying to connect the Autohelm ST50 compass display with the raymarine fluxgate compass. Both devices have wiring consisting of red, blue, yellow, green and screen. The ST50 compass also has a black wire and a white wire.
What is the purpose of these two wires?
The ST50 has two Seatalk connectors - a female and a male. Which wire color goes to which pin?
Best regards

Re: Wiring of the Autohelm ST 50 compass

On The st50 compass head, the black and white are NMEA. The ST wires are: Red is 12+: black is 12V neg, and the yellow is ST data.
