[DG] [DG11] Gps problems

[Local lad]

Hi everyone hopefully someone can help!! I have a pathfinder RL70C plotter /radar and can't get any gps signal from the rs130 GPS ariel or by nmea connections from my eclipse gps vhf which is getting a GPS signal. I have tried a seatalk converter between the rs130 and the plotter and no idea what I'm doing wrong?. Do I need to have a st70 or something connected for the gps to show on the plotter?. I also have a raymarine junction box but can't find the wiring diagram if I was to cut the white plug off so I can connect with it
Any help gratefully received I have been trying to get my head round this issue for days
