northstar 6000i to AP 35 interphase

[32hollandstick]

Can anyone tell me which wires I need to connect from my 6000i to my Robertson AP 35 to get the intherphase working? Do you need to include the ground wire too? Thanks Carl

I believe it's the purple and grey.
I will verify in the next day or so.

Yes I believe it the purple and gray too but do you also need the blue with white strip ground wire? Which port on the ap did you connect to> ive been messing with this for years and havent got it right. When you go thru the user set up it ask you to select gps1, gps2 loran: i cant figure out how to know which one to select or connect the wires to.
