I posted this here rather than in the 898c si forum because I thought some other forum member might be able to help. I am trying to get a (legacy) Raymarine S1000 Autopilot operating, and I am having trouble with the wiring configuration. The S1000 Autopilot must receive position information from a suitable GPS in order to function correctly. NMEA 0183 is suitable. Can somebody confirm that this is the correct way to wire the units using a Humminbird AS HHGPS Accessory Bare Wire GPS Connection Cable?
Hummingbird Raymarine
Red (12v+)
Black (Ground) Brown & Blue, Plus to Ground
Green (NMEA In) Green
White (NMEA Out) Orange
Should I connect the Red and black wires to the battery? To a marine terminal connector? Ground the black wire somewhere on the boat?
Here's info on the Raymarine wiring. Pin's not relevant since it looks like I have to cut off the connector to attach it to the Humminbird cable.
Wire Color "Pin Number" "NMEA Signal at S1000" "Connection at 3rd Party GPS"
Brown 1 -ve out NMEA -ve receive
Green 2 +ve out NMEA +ve receive
Orange 3 +ve in NMEA +ve transmit
Blue 5 -ve in NMEA -ve transmit
Part of the problem is that I don't understand what the "-ve" and "+ve" mean.
Appreciate any assistance.
